CompuPro Disk3

CompuPro Disk3 MFM Hard drive controllers. I can't remember which one was mine from back in the day, I ran a BBS on a couple 8" DSDD Floppy disks. I picked up another Disk3 along the way. This page will hopefully document me getting an old MFM drive booting CP/M. Probably a Quantum Q540. Both controllers appear functional

194D

Note the engineering changes on the backside. See the wires?

Files

I was able to fire these, File:Compupro.zip, up in a simulator, Altair 8800 (Z80) simulator V3.8-1 build 1296, Lot's of different CompuPro operating systems architectures and versions. I was able to boot up CP/M-80 version Q. Wish I could remember where I downloaded this, I like to give credit. Drop me a note if you find or have seen it elsewhere.

Maslin CompuPro files archives

The Maslin CompuPro files archives and the cp/m 80 2.2 Q files locally located here User retrogear on comp.os.cpm used the following procedure to convert the .td0 image to a more common .imd format. Quoted in part from this discussion. 

My quest to get a bootable cp/m 2.2q on my compupro system has led me to Don Maslin's archive. 
Don Maslin's cpm8022q.td0 is corrupted. My first clue was when too many tracks were reported: 

C:\imd>td02imd cpm8022q 
TD 1.5 8" HD MFM S-step, 1 sides ADV 14/01/1997 19:56:14 
CP/M-2.2Q system disk for CompuPro 
SSDD 1024 byte sector, 1-8, 1:1 
81 tracks, 645 sectors converted. 

So then I used samdisk to convert and imdu to expand which revealed the problem: 

C:\imd>samdisk cpm8022q.td0 cpm8022q.imd 

C:\imd>imdu cpm8022q.imd cpm22qu.imd /E

Tracks 77-80 were bogus maybe because read on an 80 track drive? 
Then I used samdisk to trim to 77 tracks: 

C:\imd>samdisk cpm8022q.td0 cpm8022q.imd -c 0-76 

Then expanded with imagedisk: 

C:\imd>imdu cpm8022q.imd cpm22qu.imd /E

Important!

From; "CompuPro CPM 2.2 Technical Manual and Installation Oct84" 

NOTE: If you have a DISK 3, be careful when changing from CP/M to 
MP/M™ 8-16™, CCP/M™ 8-16™, CP/M-86™ or CP/M® 8-16™ because the 
logical drive partitioning on the hard disk is different between 
CP/M and all the rest. However, the first and last logical drives 
are the same on all operating systems.
