Mmm...he doesn't say what the disaster is though!

I'm guessing that's a later version of !Machines than the one I have, which predates the Raspberry Pi?

I think even though manufacturer type+machine type should give a unique 16-bit machine ID, the existing machine types don't overlap between manufacturers. For example, the Acorn machine types work upwards from 1 and the SJ machine types work downwards from &FF. Some utilities (this is not an adm...

I have to say that was a gigan(e)tic amount of fun!

I reckon we distant bystanders had at least as much fun as those in attendance, we certainly did nearly all the posting! Not a single picture from the event so far: is Bletchley Park still subject to the 100 year rule?

What a way to find a bug!
Curses, foiled again!

For some reason today !Machines is only seeing my local network. Yesterday it said "Econet machine list on net 2" but today it only says "Econet machine list".

*I AM 3.254 gives error Garbled logon command. It should just return if the client is logged on, or give error Who are you? if the client is not logged on. *I AM <stn> should function almost the same as *FS <stn>. The SJ MDFS gets this wrong, giving User not known. Admittedly an obscure edge case. ...

Should be FFFFnnnn for load and exec for all Econet library utilities, as they are 6502 code but the language processor may not be a 6502.

Also I think we should probably think about a manufacturer type and machine type for the Pi Econet Bridge when it responds to a machine peek.

Quite a few of us seem to be here now:

Well, at least it means the station number translation is working:

Ah yes, it wasn't working properly earlier on, just reported local numbers and never responded. Then I got a not listening on the WhoAmI bit, but it's working now. Seems to be allocating station number 2 to each station with a different network number.

This has finally given me the chance to test (and make work!) my IsNet code: vlcsnap-2024-05-18-17h11m03s108.png Seems we have 13 networks running. Which is mine? Are we going for a world record number of Econet stations online at the same time? Might we get close to the maximum number of 32,258?

It's thinking about it...

Aha...standing by then!

Disaster...can't see anything other than my own Econet today. It was abolutely fine on Thursday night, but today, nuffink.

Has the trunk key changed maybe?

Didn't last long...anyway, we had a new TV aerial this morning. In fact there are 2 aerials on the mast, the top one goes to a 3-way splitter in the BeebStockRoom, and the bottom one comes in through the wall to the lounge. The bottom one has been replaced as the cable was fraying where it joined th...

Naturally I take all credit for the fix.

Response time wise, It's been working about the same as usual for me, but as I have been forced to regress to 1990s internet speed, with my Econet now outperforming my PC, I think that's a good sign.

I saw your nice Boot thing last night, and I played a game of Rock Paper Scissors against myself. Wonder if we can get a record attempt at longest distance for the game. All went swimmingly. Econet file servers thousands of miles away seem to perform better than my own a few feet away!

Got my international Econet working last night no problem. Connected to Switzerland and Manchester for a bit. I'll be around at the weekend to log in from time to time hopefully.

Right. I will test these very soon.

Thanks for this, I can confirm that the overwriting of the protection mask doesn't happen with DFS 0.90 when using an older version of NFS (tested with 3.34) which I presume predates the reorganisation of the workspace.

I'm glad I posted about this because this afternoon the TV updated itself and added the missing HD channels back! So I have no idea why they disappeared or what made them return!

Very interesting, although I don't know why they call them "synthetic" instructions. They are (very useful, admittedly) sample bits of code, surely?

Thank you, I did look at that website amongst about 17 others, and found that channel number on a different page but I wasn't sure what the minus sign meant. Anyway, I did a manual scan of all the RF channels individually and it didn't find any signal at all on channel 35. I bypassed the aerial spli...

I think when I cut what I thought was the telephone wire, it may have been the burglar alarm wire. I've noticed in the last few days that the sensor in the hallway doesn't light up any more. Yesterday the freeview HD channels stopped working with a no signal message. I retuned the TV and it lost tha...

The Acorn 1770 DFS ROM contains the Sideways RAM utils so without the ROM, the SRAM commands will no longer be available and to load ROM images into the SRAM module would need utility commands loading from elsewhere.

Also check that S2 is completely broken and that there is no hint of continuity between the two pads. I just had some very unusual behaviour testing with S2 closed on my Issue 2 BBC B. Normally this results in constant activity on the two data lines, a Line jammed error on any other station trying t...

Another bug in DFS 0.90...if ANFS is present, and selected on a reset rather than DFS (ie. ANFS is higher priority, or N-BREAK is used) then DFS 0.90 doesn't show up in *HELP and the message in *HELP DFS commences part way through (usually around DESTROY)! I can't tell yet whether any other function...

On a general *.* copy you might not know that any matching file happens to be zero length. I suppose the question is more why would you create a zero-length file? It could happen by accident if some file creation operation is interrupted or a file is opened and no data is written to it and it is clo...
