Umm, and 'H' series drive needs the 12821A controller board, not the 13037!
13037's are only for MAC disks, ICD drives (the 'H' drives) don't use a
13037 at all, they
just run directly to a 12821 as far as I can tell from the documentation.

But for those of us that use the earlier 1000/2100
machines, your
approach is interesting. Since I want to run HP 2000 Access TSB, I
need a disk system that emulates 7905, 7906, or 7920 drives on a 13037
disk controller attached via a 13175 host adapter. Perhaps your design
would make a good starting point.
7900A drives work as well for TSB, not just the 7905/6/20 drives. The 7900A
drives do not require the 13037 controller or subsystem, they just require a
13210 disc interface pca in the cpu. Totally different interface between
7900, to 7905/06/20. Also, be careful on the 7906, as only the A-D models
will work with TSB. The H model, which is HP-IB, will not (at least via a
direct HP-IB PCA card - if the H model 7906 drive is hooked up to a 13037
subsystem that supports HP-IB as well {not many 13037 subsystems had the
HP-IB option} then it MAY work on TSB if the HP-IB portion of the 13037 is
"hidden"). I'll have to try that someday.
Also, the host adapter and the disc controller subsystem box are both called
13037. Never heard of a 13175? Am I missing something?
Also, check out the 7900/7905/7906/7920 drive emulator at arraid.com (AEM
box I think). I hope to be receiving one of those soon.
