Master 512 "Essential" Disks
Hi All
I've just come across a box of disks that probably arrived with a Master 512 I got a few years ago.
Just checking that they have been archived?

I don't believe they have, so would welcome images of them all.

Re: Master 512 "Essential" Disks
Well the thing is I dont really trust my 5 1/4 drives.
So I would be happy to post them to someone with more robust hardware

Re: Master 512 "Essential" Disks
Thanks Daniel PM sent
Re: Master 512 "Essential" Disks
These have been received - the DABS support disk is a fungus-fest, so I'll look to cleaning that one physically when I have some time, but the other look in physically pretty good nick. I'm hoovering them up as we speak - some of the stuff was on cowsarenotpurple previously.
Edit - site wasn't working but seems to be fine now!

Re: Master 512 "Essential" Disks
Great stuff... Thanks for the help Daniel.
Hope they are readable

Re: Master 512 "Essential" Disks
Yes - all readable. Some bad tracks towards the centre on a few but nothing on those so should be fine. Just have to convert them to sector images now
Re: Master 512 "Essential" Disks
Here we go - 800kb IMG files are in the acorn DOS format, 200kb SSDs are DFS and the 360kb IMG is PC format and was the DABs companion disk that needed a wash to get the mold off it.

Re: Master 512 "Essential" Disks
Thanks, was wondering just the other day how these were progressing.

Re: Master 512 "Essential" Disks
Thanks Daniel
Re: Master 512 "Essential" Disks
Thanks for imaging these, looks like some interesting content. I'm having some trouble getting them to work with my gotek though. I have a Master 128 with 80286 Pi Co-Pro booted into DOS+ 2.1 and that seems to work OK. When I select one of the essential image files on my gotek I am unable to get a directory listing. I have some other Master 512 disk images that are HFE format and they work OK.
I'm not very familiar with all the different disk image formats. Do I need to convert the .img files to .hfe files somehow or is there a way I can convince my gotek to read them correctly?
Any help would be very much appreciated.
Re: Master 512 "Essential" Disks
Yes, you'll need to convert them to HFE *or* use the configure options for flashfloppy to define the correct geometry:
2 sides, 80 tracks, 5 sectors 1024 bytes in size per track, disk is interleaved (read 1 track at a time rather than up one side and down the other), sector numbers start at 1.
See: https://github.com/keirf/FlashFloppy/wi ... ation-File
This should roughly work, but you'll have to get the tag worked out according to your naming of the files and double checking with the example file provided:
[whatevertag]
cyls=80
heads=2
secs=5
bps=1024
Re: Master 512 "Essential" Disks
No disk error? I confess I hadn't tested any of the images, I just checked that they were all "green" as I made them.
Re: Master 512 "Essential" Disks
No disk errors that I've seen. The suprstar utility loads OK, but when I hit ctrl-shift-* I get a blank mode 7 screen with a blinking cursor and no way to issue commands or to get back to DOS.
I haven't found time to check out all the other disks yet, if anything odd happens I'll let you know.
Thanks again.
Re: Master 512 "Essential" Disks
I seem to have resolved this problem by updating the firmware on my PiTubeDirect to the latest Hognose fixes release
PiTubeDirect_Hognose_Fixes_20230621.
Now I can use suprstar, milfix and pcce successfully. Thanks to all involved.

Re: Master 512 "Essential" Disks
That's great news, thanks for the update.
This version includes a significant change to the 80x86 Co Pro: it now emulates an 80186 with DMA data transfers rather than an 80286 with NMI data transfer.

Re: Master 512 "Essential" Disks
I'm guessing that's why PCCE didn't work with the 286 emulation? Because it was expecting specifically a 186?

Re: Master 512 "Essential" Disks
Apologies for the thread archaeology, but PCCE was doing stuff with the NMI handler and that was interfering with the NMI data transfers that were originally used (and why the CPU emulation was an incomplete 286 - only the real mode side was there, if my understanding is correct). With the switch to DMA, PCCE is no longer confusing things, and the emulation is now IDing as an 80186, which also matches what was present in the real hardware.MillieTD83 wrote: ↑Sun Jun 25, 2023 12:56 pmI'm guessing that's why PCCE didn't work with the 286 emulation?

Re: Master 512 "Essential" Disks
I had this same symptom just now on my physical Master 512. In this case I ran 'SUPRSTAR' without the A or D parameter - which defaults to D (for DFS) per the SUPRSTAR.DOC instructions. But (for whatever reason) my DFS was unplugged. If I run with 'SUPRSTAR A', then I can enter the ctrl-shift-* fine.No disk errors that I've seen. The suprstar utility loads OK, but when I hit ctrl-shift-* I get a blank mode 7 screen with a blinking cursor and no way to issue commands or to get back to DOS.
