MYIDE will not run on 8080/8085.  On 2.2 It should be OK I think, if not only 
minor console I/O mods required.

Subject: [N8VEM-S100:7393] Re: V3 Dual IDE/CF S100 Bus board initial checks

 

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?

I'm checking in with a progress report and to say thank you John for the board

This v.3 is my first experience with the IDE/CF board. I've installed all the 
non socketed parts, verified voltages and then the two GALs. Rather than use my 
front panel or non existent monitor board (except a CCS Z80 CPU more on that 
later) I assembled and ran this small program on a stock (except the disk I/O) 
Altair 8800b to exercise the ports.

 

                ; jha 6/27/2015 testport.asm
                ; test the S-100 IDE v.3 port addressing
                ;
 0100                   org     0100h
 0100 DB30              loop:   in      030h
 0102 C30001            jmp     loop
 0105                   end

 

Before I run the program I clip on the logic analyzer of my S-100/N8VEM 
extender to pin 23 of GAL 1 ADDR_8255* it's HIGH. I run the program and I get a 
couple visible cycles/pulses then the HIGH and LOW lines are cycling so quickly 
I can't see them cycle anymore. The LOHI and HILO transition leds are on too. 
<pause> May as well put a scope on it. I've got a pulse width 480ns at 100khz. 
I'm not seeing it on the 8255 pin 6 CS*

 

Looks good right? I'm a bit curious about the initial ?settling? time when I 
first start the test program. I'll move on to some of the other tests I see in 
the v.2 notes.

 

Has anyone, maybe Bob Bell, ever run the MYIDE ROM on the California Computer 
Systems (CCS) 2810 Z80 CPU? 

 

Does anyone have a system generated for a CCS 2810CPU, CCS 2422 floppy 
controller and the IDE/CF card?
