Hmmm... What's the difference between the Z80-A and the Z-80AA. Clock speed? Functionality? I'll take you up on the offer of the EPROM image. Chris L. offered to send me images also but is better to have several that can be compared. Thanks. Dave

A little more digging...turns out that that is the checksum for the Z80-AA pod, I guess it is essentially the same as the standard Z80 pod. Hmm, need to take apart a few of my spare Z80 pods to figure this out better...time...

Hi Folks,
Has anyone archived the EPROMS inside the 9010A pods? I need someone to verify the checksum of mine or send me the image of thier EPROM. I've disassembled the code in order to understand the communication between the pods and mainframe but there are several instructions that just don't make sense. The EPROMS should all be archived anyway, they're getting to/at that age where the bits start to evaporate.
The STANDARD checksum that I get is: 785E
Thanks in advance. Dave
