These file are dump of PALS and PROMS in the Overland Data TapePro
3610 tape drive. I think the dumps are good but when I tested the drive
after reassembling everything worked fine except I can't write 6250 tapes.
Always gives block error. Seems to be writing problem since 6250 tapes I have
read file. Will write 1600 tapes. Since I used this drive for dumping tapes I 
don't know if it wrote 6250 tapes before I took it apart.

Parts are likely same as 5612 and 5614 since they use external SCSI to Pertec
board. There seem to be multiple revisions of the drive with different date and
part numbers for the programmable parts.
