You have to remember that the stock MDS800 8080 setup had 64KB of non-bankswitching memory, so for two users, this is about right, as all of the OS code has to be resident.
Useful for a demo, but little else.
When I did the MP/M 1.1 adaptation for a machine with bankswitching, I had a minimum of 192KB available, switchable in 1KB chunks on a system with 5 serial ports. Not great, but better. Ultimately, we rolled our own non-DRI scheme, where the user programs were all P-code compiled BASIC. That worked very well, without the headache of trying to get programs that were never intended for multi-user systems to run.
Probably the most successful, if you can call it that, approach by any vendor was to give each user his own CPU card and memory and coordinate things through a special executive running on its own CPU. (e.g. Molecular).

The series II systems had on-board SD controllers using intel's chip (what was it 8272 or something) for the internal drive.
Then there was a board set for either SD or for intel's proprietary M2MFM.
MDS800 had one or both of those FD controller board pairs.
Mine has the DD board pair so I can't read SD disks on that machine at all. Such a pain.
Been looking for a SD set for 3 years.
Some 3rd-parties such as Zendex had an all-in-one board but I've never seen one.

Internal one was the 8271, I think. The 8272 was a cross-licensed NEC 765 and came a bit later (ca. 1980 or so).
Given that the IBM 3740 FM was pretty much an industry standard, it boggles the mind that the Intel M2FM board couldn't handle FM, even on a read-only basis.

I have most of the Disk Software for the Altos 8000 and don't remember ever getting them to copy under image disk. I have 2 SD 8" systems and both had problems. Of coarse both now have Dead Floppy drives in them. I just use real system to make copies. I believe Chucks software was able to read them, but that was a long time ago.

I haven't had any problems with ACS8000 floppies with IMD. Could it be your setup?

It won't boot because the disk is missing track 2. Track 2 should be DD with fifteen 512 byte sectors, but it only has a single 128 byte sector which is a copy of the first sector from track 1. Oddly there is another copy of CP/M 2.24A in TD0 format that is dated a couple of years earlier which shows the same missing track 2 problem, but it isn't exactly identical. There's a couple of bytes which are different so I don't think the IMD was created from the TD0.
I found a zip file which had all the files from CPM224A and I was able to rebuild the missing track 2. I posted the repaired disk image here: https://www.retrobattlestations.com/Altos/disks/ACS-8000/8500/bootable/

If anyone cares, I still have the OEM 8" disks for MP/M II, which includes stuff like PL/I and RMAC. Standard SSSD IIRC, bootable on an MDS.
