Hi,
Easiest is to simply make the measurements and post the results to
this group. We can sort it out. Resistance measurements are not expected
to be identical. We are looking for big differences between similar circuits,
not small variations.
Of course you must make any resistance measurements with the power
turned off.

Thanks for that info Bob - I do not have an oscilloscope, not sure I know anyone out here that could check that. When you say to check the resistance from pin 2 on IC2 on KLM371 to ground, and then compare the resistance measurement from that signal to another data bus pin, what would I do if these are not identical? I think I see the steps that you recommended for me to test, but I am not sure if I understand what it is that I should do if the measurements are different.
I'll try to look at those tonight, plus the D0 for those two chips. I'll study the schematic some beforehand to see if I can pinpoint these, this isn't something I have a lot of familiarity with but I will do my best since I really want to get rolling with playing my polysix again. Thanks.
