When repairing a TU60 drive that had faulty DEC8881 I replaced them with
DM7439. They were $2.76 each when buying 25 pieces. The original faulty
chips were marked 7439 on the backside.

I hate to open this discussion again, but Jack Rubin
and I are both
repairing DEC Omnibus boards and need some DEC 8881 driver chips.
Since my PDP-8/e only has a 20 slot backplane and only has a few
boards installed I will try a lower drive SN7401 in place of the DEC
8881.
