I guess I spoke too soon – I’m getting BDOS errors now. Not sure why since the drives work fine with the Gazelle. Arrrgh.

First, happy Father’s Day to all the dads on the list. Great day expected here on Long Island so doing a lot in the yard. 


Years ago when I got my IMSAI it didn’t have drives, so many may remember my implementation using 5.25” HD drives (and the subject of two VCF presentations). I have an 8” drive system that I use on my Gazelle (dual Shugart 850’s) so I thought I’d see if connecting them would work. 


Indeed it does! I only had to modify the step rate parameter for the drives (4ms) in the monitor ROM and off it went. Today I’ll finish creating a “base” CP/M system disk — all it has is the system tracks. Then I need a good XMODEM program for CP/M so I can transfer files easier. 


Enjoy all.
