Had some time to work with my v.3 IDE/CF card today after completing assembly.
My first experiments were using Josh's JAIR board. However I believe the JAIR uses, by default, I/O ports at 030h which is where my GAL was burnt for me by Gary. I get the signon message and initializing then locks up. I have a CompuPro system running 8" FDDs with an 8085 / 88 card. Same results hangs after signon / initializing message. Interestingly SURVEY.COM locks up on the CompuPro after not displaying port 030h that I believe the IDE/CF is configured for. Note test I ran at beginning of this thread seems to indicate GAL is responding to port 030h. I did install the 1k pullup R118. For U110 I used DM74S04N. I tried with reset empty and on the right most two pins. Any suggestions for some further debugging? *Questions* - Can MYIDE.COM run on an 8080 or 8085 CPU? - Can MYIDE.COM run under cp/m 2.2? cp/m3 NOT required for MYIDE.COM test / utility program? <https://lh3.googleusercontent.com/-A_NxunGsMqg/VaRocqaw95I/AAAAAAAABAw/oAydIEossQU/s1600/S-100%2BIDE%2BCF%2Bv.3.png> - jeffa On Saturday, June 27, 2015 at 2:10:53 PM UTC-7, Jeff Albrecht wrote: > > I'm checking in with a progress report and to say thank you John for the > board and the mailing to all of us.
