Hi,
I remember I used Linux with an AdvanSys PCI adapter to successfully read a disk
connected through an ACB4000. It's been a while but I believe I had to run
an old kernel which I compiled myself with support for ACB4000. Might have
been that a patch was applied.
All I found in my archives is

I have a sun 3 system with acb4000 and suspect the protocol
was not fully sorted in that time frame. They can be fussy

I have the same problem with Torch Triple X disk which uses OMT SCSI/MFM
adapter.
I believe the best solution is to use David’s MFM emulator board.

Hi,
still working on backing up the Tektronix 440x disks. My current problem
is that the ACB4000 SCSI-to-MFM adapter doesn´t support SCSI parity.
I finally managed to find a PCI SCSI controller (Adaptec 2940) and a
Pentium 4 PC with PCI slots and installed OpenBSD 6.7. I disabled parity
