Re: [Techtoolslist] Tweaking a 9010 z80 pod to be a z80b pod?
I can't think of any reason why it wouldn't work if you swopped the CPU in the pod for a B version, although I've obviously been lucky, my Z80 pod works fine at 6Mhz without me needing to do that. (I did however, replace the 12Mhz CPU with a 16Mhz one in my 68000 pod) --- Trying to get a pair of spy hunter boards working. One is brain dead and I want to run it through the 9010 paces. But I don't have a z80b pod. Is it possible to mod a z80 pod to be a z80b pod? _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
Anyone have the schematics / manual for the z80aa pod? I want to do a quick compare of the z80 and z80aa pods.

Thanks, David
According to my notes the Z80 and Z80AA pods have the same ROM, I suspect the only difference is the CPU... The Z80 PDF is up on the FTP site, but nothing for the AA other than the ROM image. John :-#)#

MCR board sets are peculiar things. I have had only limited success using a 9010 with them. I found that most of the time a Run UUT simply wouldn't work but occasionally it would. The chances improved when I burnt my own set of ROMs. This was Tron incidentally. I think it had something to do with the speed of the ROMs and the Z80CTC. I'd have to find my test rom set to look up the speed of the roms that i ended up using. I seem to recall that I was able to do rom and ram tests ok. I should probably point out that this is going back about 5 years now, hence the slightly vague response! Martin. On 1 May 2009, at 09:17, mike@the-coates.com wrote:

I s'pose you could at a push swap the crystal on the game pcb to a slower one to do the fluke testing stuff with the slower z80 pod ??? Obvioulsy the video wouldn't be to spec and such like.... but just a thought... feel free to blow me out of the water... Once the fluke has found faults and you have repaired them, you would re fit the old crysal and continue the troubleshooting...

Regards, Colin The problem might be with the CPU cable from the pod - the shorter the better, or find the twisted pair type CPU cable and put it on the Z-80(AA) pod.

Hmmm...Intereresting..... I've not got my hands on a Z80 pod yet.... ( will be borrowing one once I can go and sort a deal out), so can't comment on the cable fitted as standard.....but I do know my 6502 pod has a twisted pair cable though. Thanks for the insight...
