We’ve been making banners with the IBM 5362 (System/36)! More midrange people at #TechXchange who recognized and knew how to work with the machine than I could have ever expected! Lots of folks very excited to play with some old IBM gear and get some printouts to take home!

March 22 marks the 60th anniversary of the introduction(*) of the Digital Equipment Corporation PDP-8, which more or less introduced the "minicomputer" as a new category of computer. It cost a mere $18,000 and fit on a desk, and while it was a small, simple computer, it became extremely popular.

Got it all working and reassembled. There was a cracked trace causing an address line to be connected to only two of the RAM chips, and nothing else. This was acting like an antenna and picking up noise.

Still missing a couple keytops (1, Z, and left Shift), but I found a couple I could substitute.

Well I guess this is why I got this Neo Geo 4 slot board-set for free… Looks like someone diagnosed the bad ram then tried replacing it with a hot brick and lead free solder or something. We’ve certainly all been there at some point in our soldering journey… Let’s try and fix it!

Apparently the Roland SC-88, the original tall unit, has SMD capacitors on the logic board. That was fun to clean up and replace. Trying to clean up the leads of the one chip lead to me messing up some pads. Doh, had to whip out the scope for a fix. Works great now.
