Tektrionix VAXBI board and DC100 training tapes?

[Mattis Lind]

An ex DEC engineer offloaded some stuff that he had found in his attic.

It came together with a tektronix 1241 Logic Analyzer.

Someone that can tell more about it?

Then there were some DC100 tapes in a huge heap of TU58 diagnostic tapes
for VAX-11/730 and  VAX-11/750 that looked different.

They were marked "BI-SYNC TRAINING TAPE" and "ASYNC TRAINING TAPE
TAP-895-103-1.0 3.04"


Anyone recognize what that could be?



BTW. What are the status of various 11/730 and 11/750 diagnostics on TU58.
Are those already dumped? It takes some time to work with TU58 so if
someone already done all this I might skip dealing with them.

I know of only one place that has TU58 dumps.

Anywhere else?
