Speech ROM and Other Components
Speech ROM and Other Components
From the photos of Colday's new BBC micro board, there were two TI chips in the speech upgrade. IC99 is the speech processor and is generic while IC98 is, if I remember correctly, speech samples from Kenneth Kendal, the BBC newsreader. Do we have that archived anywhere?
What else was in the speech upgrade? Is there a service ROM to drive it?

Re: Speech ROM and Other Components
I did come across the user guide whilst trying to hunt one down. There are references to the components and planned future cartridges early on. Unsure if these sockets mentioned to the left of the keyboard were used for further speech expansion?

Re: Speech ROM and Other Components
The US BBC Model B has its own phrase ROM different to the Kenneth Kendall one. I think the speech upgrade, including the serial ROM socket on the keyboard, was fitted as standard. Apart from that, nothing was ever released, and having software in ROM cartridges rather than speech data, never came about. Sprow has more info here:

Re: Speech ROM and Other Components
Re: Speech ROM and Other Components
Thanks Ken looks like good clearance there. In the absence of me having a spare socket do you think it will fit without? Looks like it might from the picture but hard to tell!
Thanks in advance.

Re: Speech ROM and Other Components
It just about fits. The thru hole pins from the IC on the underside of Retroclinic board will marginally clash with the top of speech IC, and will cause the Retroclinic board to sit at a slight angle. However, the Retroclinic board does appear to almost fully plug into the 40 pin socket, so I think it would work. That said, I would just buy a 40 pin socket to avoid the clash altogether.

Re: Speech ROM and Other Components
As you might probably have guessed from my question, I was following up on the request to add speech to B-Em. Thanks everyone here for some very useful information and especially also to Frank Palazzolo who wrote the MAME module I have adapted. It is worth noting that the MAME version was informed by discussions with one of the original designers, a US patent and de-cap of the chip as well as the data sheet.
Here is a quick video of B-Em speaking from the vocabulary in the Phrase ROM A - thanks for Simon Inns for archiving that ROM as part of his project to make a replacement.
https://youtu.be/QIEv25rAJo0
This version is on GitHub at https://github.com/stardot/b-em/tree/sf/speech
I think the next step would be to test the "Speak External" command, i.e. where the data is provided by the CPU rather than read from the serial ROM. Does anyone have a suitable test case, i.e. something that will speak something without too many keystrokes from initial loading?

BTW, if you have the latest BeebEm installed then you'll already have a folder full of alternative PHROMs, including the US version, in UserData.
Did you change anything from the original MAME code?

Re: Speech ROM and Other Components
As a further note on the speech upgrade I wonder if a mistake was made in constructing the Phrase ROM. There is a command, Read and Branch which, as far as I can tell, reads an address from the ROM and then updates the read pointer to the address just read. That would seem to be an ideal thing to use when wanting to speak a word by index number. What the OS actually does is:
- Calculate the offset into the index of words stored early in the chip. The header is just the right length that the lowest index that speaks something, 32, goes to this without any subtraction.
- Load the address of the index entry into the ROM (via the speech processor)
- Read two bytes from this address, reversing the order of the bits in each.
- Send those same bytes back as the new address.
- Tell the speech processor to speak the word.
- Calculate the offset into the index of words stored early in the chip (as before).
- Load the address of the index entry into the ROM (as before).
- Issue a "read and branch" command.
- Issue the speak command.
Re: Speech ROM and Other Components
The B-Em version is C, rather than C++, doesn't have MAME's save and re-load logic, and doesn't yet have the equivalent for B-Em, and is simplified in that it doesn't need to be able to emulate the other chips in the family. But the core of it is mostly a copy and paste. It uses the same lattice filter, the same function to parse the frames, the same function to produce a block of samples to hand off to the sound system.
Re: Speech ROM and Other Components
Hi Ken,
Just a quick note to say thanks for the advice. All nicely fitted after a nervous moment inserting the TMS5220 into IC99,it was very stiff to get in.

Re: Speech ROM and Other Components
Another question on the Speech upgrade: was it available for the Master?
Re: Speech ROM and Other Components
Nope. I believe the speech I/O addresses were assigned to the RTC chip on the Master.

Re: Speech ROM and Other Components
I find it surprising that OS 1.20 had explicit support for the Speech system built into it, when the same was not true for arguably more important optional components like the 8271 disk system.
Re: Speech ROM and Other Components
I'm guessing that there was investment in the UK with Kenneth Kendall while the DFS was being done in Oz iirc.

Re: Speech ROM and Other Components
OK, I now have a version of B-Em that both speaks words from the PHROM and runs Tricky's Starwar speech demo which uses the "Speak External" command.
This is in GitHub at: https://github.com/stardot/b-em/tree/sf/speech
For Windows there is a pre-build pre-release at https://github.com/stardot/b-em/releases/tag/sf/speech
The PHROM test case I have used, and the demo in the YouTube screen capture is:
The Tricky demo is linked up-thread.
The speak external was much more tricky to get working. Speaking from the PHROM required no synchronisation with the emulation of the 6502 as, once the speak command was received, everything else could be driven by requests for sound samples using reasonably large buffers. For speak external the processing this is not the case and underrun happens quite easily if the sound stream demands more samples than there is data in the FIFO to produce and the 6502 emulation won't run until feeding the sound stream has finished so this required a change to synchronous working with more but smaller buffers.
Then we have the way the Model B was more popular than initially predicted and the same may be true of discs. I am also not sure it would have fit.

Thanks. It was actually having a Master lock-up when trying to write to the CMOS RAM that made me start to question it. It certainly seems that the CMOS/RTC has taken the Speech upgrade's spot on the slow data bus but I know sometimes things just got moved on the Master. So I have just made the integration of Speech with the SDB dependent on the machine not being a Master.
It may seem surprising looking back, as we now know the speech upgrade sold poorly and the concept of ROMs in cartridges to work with it never really took off, but it presumably made sense at the time. The cassette filing system was the one that initially received the effort. The ROM filing system seems related and is certainly tied up with the speech system as serial ROMs that would be plugged into the "ash tray" to the left of the keyboard could work with it. Arguably, those ROMs were the whole point of having the ROM filing system - it's a pretty slow way to access a normal sideways ROM.Rich Talbot-Watkins wrote: ↑Sun Nov 28, 2021 11:39 am I find it surprising that OS 1.20 had explicit support for the Speech system built into it, when the same was not true for arguably more important optional components like the 8271 disk system.

Re: Speech ROM and Other Components
I think the falling price of EPROMs was a significant factor, combined with the single-source nature of the serial ROMs and nobody at TI promoting it. I remember seeing an emulator so you could try out your content in EPROM on the emulator before sending it off to TI to make a ROM, but they weren't readily available or promoted, and were too big/expensive to use other than as a prototyping tool. With a sideways ROM product, you could start off in EPROM with a view to making a mask ROM if sales took off, whereas with the serial ROMs you had to make the immediate commitment to the big volume - which would have been a huge ask for the first few such product given that few if any users actually had the 'ashtray' fitted.Coeus wrote: ↑Mon Nov 29, 2021 1:09 am It may seem surprising looking back, as we now know the speech upgrade sold poorly and the concept of ROMs in cartridges to work with it never really took off, but it presumably made sense at the time.

Arguably, those ROMs were the whole point of having the ROM filing system - it's a pretty slow way to access a normal sideways ROM.
Effectively, the prospects for serial ROM cartridges as a means of software distribution were killed off by the decision not to fit the 'ashtray' as standard (maybe it would have been OK with the actual speech chips left out as they were an easy DIY upgrade, but the complex, soldering-required, upgrade for the socket wasn't something that could reasonably be required as a pre-requisite for a high volume piece of software). There was no practical way to make cartridges an optional alternative for packages primarily being distributed on cassette or floppy.
It was originally intended that DFS would be in the OS, but it became clear at an early stage that it had no chance of fitting; it was then pushed out into a 4K sideways ROM (on the assumption that it would fit since it was a port of System 3 DOS which fitted in 4K), then when it came to actual implementation it was found that with the extra things a BBC version needed to do 4K was an extremely tight fit and there was a sigh of relief when the price of 8K EPROMs came down enough that it could expand to 8K. The disc system was an expensive upgrade overall and could afford a sideways ROM as part of it.Rich Talbot-Watkins wrote: ↑Sun Nov 28, 2021 11:39 am I find it surprising that OS 1.20 had explicit support for the Speech system built into it, when the same was not true for arguably more important optional components like the 8271 disk system.
The speech filesystem on the other hand shared most of its code with the cassette, and the speech upgrade was in principle fairly cheap such that adding a sideways ROM to support it would have been a big percentage increase. Also there was almost certainly politics involved; I don't know the exact sequence of events, but the "Kenneth Kendal" part of the project will have made these otherwise minor technical decisions visible at a much higher political level. In fact, speech in the OS (using the TI standard ROM) was done fairly early, I think before much progress had been made on DFS, but the KK ROM took much longer, well after DFS had been finished.
DFS was _not_ done in Australia (nor Econet), despite persistent misinformation to that effect apparently stemming from some misleading Wikipedia entries.
DFS was a port of the Acorn System 3 DOS, done in the timeframe January-March 1982 by John Cox, working at Acorn Fulbourn Road. There were subsequently some independent DFS implementations (though none that I'm aware of from Australia), but it is not possible for any of them to have pre-dated the official DFS since there was no support for add-on filesystems in OS 0.1 - the first releases of OS with that support (0.9x) were issued to enable early DFS sales.
Barsons in Australia were however pushing very hard to get early access to the official DFS, and the efforts they had to make given the limited support from Acorn are probably the source of these rumours. The true story is documented in Brian Cockburn's ABug video:

Re: Speech ROM and Other Components
Ah, that's an interesting bit of history. I guess I always imagined that the disk system would need the filing system as a service ROM, but it might've made sense for the low-level / NMI interface to be in the OS. This would make more sense later on, with the move to 1770, so that the different filing systems could share the low-level OS layer (although that of course would have required an OS upgrade!). I suppose there's also then an argument - why not Econet too?arg wrote: ↑Mon Nov 29, 2021 11:16 am It was originally intended that DFS would be in the OS, but it became clear at an early stage that it had no chance of fitting; it was then pushed out into a 4K sideways ROM (on the assumption that it would fit since it was a port of System 3 DOS which fitted in 4K), then when it came to actual implementation it was found that with the extra things a BBC version needed to do 4K was an extremely tight fit and there was a sigh of relief when the price of 8K EPROMs came down enough that it could expand to 8K.

Right, makes sense. I don't suppose the speech stuff takes up an enormous amount of the OS in any case - far too little to warrant an expansion ROM. The OS also has minimal support for other extras like the 1MHz bus, so I suppose it wasn't any big deal to add it, given the overlap with the tape filing system. It's funny though how the speech system was deemed so unimportant in the end that it was discontinued entirely when the Master came along!The speech filesystem on the other hand shared most of its code with the cassette, and the speech upgrade was in principle fairly cheap such that adding a sideways ROM to support it would have been a big percentage increase.
Re: Speech ROM and Other Components
That is another thing that is easy to see with hindsight. Looking at the lower filing system numbers, and assuming these are allocated in order for development, or at least having the idea it might be developed, we have:Rich Talbot-Watkins wrote: ↑Mon Nov 29, 2021 1:15 pm ...but it might've made sense for the low-level / NMI interface to be in the OS.

Code: Select all
01 - Tape
02 - Tape
03 - ROM
04 - DFS
05 - NET

07 - IEE
So, at that point, with two disc-based filing systems and three controllers: the i8271, the WD1770 and the hard disc interface it would indeed make sense to have an interface between a filing system and a raw disc. To be fair, I think all these filing systems allow sector level access from applications using OSWORD, but different ones for different media and the missing bit is having the filing system access discs via the OSWORD concerned so one could implement a driver for a new kind of disc and have an existing filing system use it.
JGH addresses this in HADFS which can be made to run on top of any block-based media by implementing a particular OSWORD.
Interestingly CP/M has an interface of this type between BDOS and BIOS which is a perfect example of how to do it if you want to scupper any chance of decent performance, by working one sector at a time. OSWORD &7C is a much better example, i.e. logical block addressing and transfer as many blocks as the caller wants - so it could be a whole file. There remains some complexity about how to handle special operations, for example formatting.
And yet the concept of the ROM cartridge, rather than being dropped, became a built-in part of the machine. Presumably the difficulty due to a lack of programmable serial ROMs remained with the TI system, hence the cartrdges using ordinary ROMs.Rich Talbot-Watkins wrote: ↑Mon Nov 29, 2021 1:15 pm It's funny though how the speech system was deemed so unimportant in the end that it was discontinued entirely when the Master came along!
Re: Speech ROM and Other Components
Back on the topic of speech, what do we know of the PHROMs in the BeebEm respository. We have (with MD5 sums):
The first thing to note is that vm61002.bin is a duplicate of phromus.bin. Listening to the words in phromus.bin suggests to me that it is not a direct equivalent to the UK version, just with a different speaker. The UK ROM seems to have a very general set of words. The selection of words in the US ROM, though, seems to be aimed at having equipment provide information about industrial processes to a person, possibly as part of an alarm condition. Maybe it could even be part of equipment that would generate an automatic telephone call to a remote technician and deliver a suitable message.
The next ROM, vm61003.bin, does not seem to be in Acorn format, i.e. it doesn't seem have an index that can be found by the BBC OS and therefore speaks sounds that seem somewhat random. That is as far as I have got so far.

Re: Speech ROM and Other Components
Thanks. So the US ROM that had a different word set is described there as the industrial vocabulary which matches my description. This one does seem to contain an index in the style used by Acorn. The next three seem to lack this index but I have been able to index them by simply starting at address zero and letting VSP parse until it gets a STOP frame then pick up the new address. In the following the addresses are in hex. A ? means I could not make out what the word was so maybe someone else can have a listen to fill in the blanks.Pernod wrote: ↑Mon Nov 29, 2021 7:45 pm They're documented at https://en.wikipedia.org/wiki/User:Lord ...
