OK, I get the hint. I'll make a list of what I have and post it up for comment. I'll then image in order. It's about time. Most of what I have is for the 16 series running Xenix, but I do have some II specific stuff.

Everyone,
The community is small, but there are at least 5 people on the board that I know of who have unique 8in media that has not been imaged. I'm sorry if that sounds curmudgeonly, but I'm not well By my count at least 95% of the images in pski's model2archive came from me, beit directly or indirectly. Please people image and share! *cough* *sneeze*
@Lamar
I do have the source code for LS-DOS 6.2, but no disc image. I'm pretty sure Pete can image 8in, but I'll let him respond to that. Yes, the code for 6.2ßAC is a bit of a nightmare, and disassembled 6.3.1A code does show a lot of fixes and bugfixes.
It's good that FDIV is in contact with someone, I feared the worst for a while. I'm very happy that he's going to share what he can, when he can.
It was because of Frank Durda's challenge stating that "it couldn't be done - certainly not in BASIC!" - ... Everything is fine, except when the DMA and FDC is involved or INTerrupts are enabled... then it becomes a somewhat capricious beast, not unlike a real Model II.
Even when following the logic of some of the Model II boards, there is endless try-and-fail to accurately emulate some things, because the Model II boards aren't doing what they are supposed to.
The Arcnet process is commented out to a stub, because that board's wacky interfacing to its memory and the 80C26 had so many many problems I gave up (I will deal with it later). Ask Frank about Arcnet boards - I dare you! ...
How do you go about getting a ROM added to MAME?
..... and I have the temperature-controlled solder/desolder/hot-air rework station...
@Iowen
You got the right tools to do the job, but be very careful with the PCB it is of a very bad quality and the soldermask
doesn't work anymore after all those years.
(I had to replace the XR chips on my keyboard, which was a terrible job)
I hope you can read the data and improve Mame. :D
That'd be from the lubricant drying out on the disk sleeve - generally the precursor to an all-out oxide dump, so you're lucky there.pski said:I guess we got lucky with the LS-DOS 6.2 disk because it squealed like a pig when I started imaging, but it did complete successfully. Not sure if I can image it again successfully, but hopefully what we got exactly was what was on the disk. I'm not sure how good the error correction and/or read verification is in ImageDisk.

LS-DOS 6.3.1A has in the same place (from 10h): "LS-DOS63Level-1A"
Now it will be interesting to see how much of the LS-DOS 6.2 code matches up to what's on this disk.

To solve the problem I have setup a new installation of Mame64 / Mess version 1.70....
Use mess interface version 1.70

Does anyone know how we could use different M2 boot roms in mame? The current trs80m2 rom folder(see below) has a bunch of different roms which seem to be the BINs of the M2 roms. Specifically, if I want to use a particular version of the boot rom, how can I tell mame to do that? Thanks.
