Zitat von

By comparing the files, I can sometimes make a good guess which one is the older/newer revision.
Then there's also the module serial numbers which luckily Berger has kept track of. This one was a lower number. (make sure first that the module wasn't upgraded)
*edit* oh, and I'd expect prototype Maestro modules before Leonardo was sold to be version A.
The EPROMS of this B version are from week 22/23, 1987.
Thank you hap!!!
I appreciate your prompt and logic answer!
I also understand how important it is to add photos of device Serial #, PCB and PROMs when extracting SW.
