The pod has a cpu internally to match the board under test. The differences between the 6800 and 6802/6808 are clock and bus request signals are different, plus there is an enable on the 6802/8 that is missing on the 6800. You might be able to use the 6800 pod to do simple tests on the 6802 stuff, but I haven't tried it out, certainly it will not harm the pod as the +5 and grnd are all the same. At worst it will simply claim that certain control lines are wrong. Perhaps a interface plug could be whipped up that goes between the 6800 and the 6802 socket to fake the control lines that the 6800 pod needs to see?

Well, if you have a 6800 pod, it might be possible to make it able to test the 6802/6808's as well.

I was using the 9010 today and accidentally plugged a 6502 pod into a board that used a 6800 processor. Hmm, could read and write to RAM, and do a ROM checksum test, only when I tried to "RUNUUT" did I notice the error. No risk to the pod as the 6800 and 6502 share the same Vcc and Gnd lines, as well as Data and Address lines and some of the clock and I/O ports. R/w is the same for example...I think a 6502/6800/6802/8 multipod may not be so much trouble after all...anyone have lots of free time? I was able to get the Series 90 8085 test fixture to become a Z80 unit, just tidying up the rather messy sketches before I show how it works. Have the code for that as well... Anyone have a 6802 pod and have the Pod Eprom stored? I have the 6502 data if anyone wants it. John :-#)# At 08:12 AM 8/9/00, John Robertson wrote:

Now if you could do 6809 or 6502 on the Series 90 unit.....

Well, I am sure it could be done if someone wants to figure it out...the address and data lines and most of the control lines are known (at least to me ;-), but the ROM is specific to the CPU, but I suspect it might be a lookup table for that. Anyone want to take on the project? I'll gladly share the info I have, and the seller of the Series 90's (8085) has five left at $39US plus shipping if all five are bought. Fluke was less than helpful for parts or ANY information on the units. Seems that they are pretending it didn't exist-was Philips rude to them or something??? At 04:25 AM 8/9/00, Kev wrote:

the same for example...I think a 6502/6800/6802/8 multipod may not be so much trouble after all...anyone have lots of free time? Well, for the 6800/02/08, at least the code should be almost 100% compatable (or could be made to be) - a multi-pod with 6502 mode would have to switch out EPROM as well. Interesting side note, the 6802 pod has a 6532 for support.
Anyone have a 6802 pod and have the Pod Eprom stored? I have the 6502 data if anyone wants it. I have a copy of the 6802 pod code, EPROM was labeled "V1.0". I certainly could share. Anyone have any newer s/w for the 9010A? Mine boots with a version code of "2B".

I sent Corey (I hope) a copy of my version 3.1 for the 9010, anyone else need it? Perhaps we need a second support page (outside of spies) with these files, I don't want to due to copyright issues, but a private spot? John :-#)# At 07:24 PM 8/9/00, Corey Stup wrote:
