I regret that when I obtained my Straight 8 system in the early 80's I chose not to take the ASR-35. In retrospect this was a huge mistake. My thinking at the time was in addition to not having room for it it was noisy and would be difficult to maintain. I used my Processor Tech Sol 20 as the

The biggest one, which started me down the path of software preservation, was giving away all the DECtapes that were on UW-Milwaukee's TSS/8 system to Gary Coleman in Cleveland. I managed to find a box or two that other people on the system kept, which is where what I have of the TSS/8 sources

No they weren't SCSI. Those were only through either a "spock" or "tribble" MCA card. Those were the code names. I have *no* idea what the "real" IBM designation was. ;-) The desktop PS/2 machines (50, 50Z, 70, etc) were all designed with robotic assembly in mind (that's why there are no

I have two big regrets (lots of little ones). the first was a Litton 1251 I got in the early 1980s for $25 from the State of Oregon. 5 2X3' components, control, printer, tape reader/ punch and two 200K drum memory units. Played with for a while and scrapped it when aluminum was bringing 80 cents
