[Techtoolslist] Data io 29a with Unipak

[Kirk Spradling]

Probably not much help, however the Unipak manual may provide a place to 
start.  Here is a link to one: 
http://bitsavers.informatik.uni-stuttgart.de/pdf/dataIO/981-0003-002_UniPak_Jul86.pdf

Page 5-01 has the bit supply schematic.  Start checking things in that area 
would be my best guess.
