With the info and help from @braedel@Jamesv833 and @Contract_Pilot I got one of the 29B/2B systems up and running on latest firmware, windows software and running off USB.
In my adventures between customers with this thing cracked open on my desk, I either pooched something or it just finally decided to die, I ended up with an original Unipak (not 2 or 2B) that now will not allow the system to boot.
If am wondering if anyone has an extra unipak they would trade for. I have the 2B on the other set, but the Unipak at rev11 can burn old proms and 2708 for me, the rest i will use my smaller, newer programmers for.
I would take Unipak, 2 or 2B, let me know what you have, I want to get this second system up and finished and ready to go back out in the wild.
