Gregory's ServerOK i let it sit and then rewrote a new reference disk. perhaps it detected the type 2 planar and screwed something up in the type 1 planar's CMOS?

  @tubetime What kind of packaging is that? I’ve never seen anything like it. @foobarsoft IBM's crazy odd MST modules (later versions of their SLT modules that they invented in the 1960s)  @tubetime Because of my unique personal history, my first thought was "I wonder if those were made in Burlington" (which was actually Essex Junction). @wollman see where it says "IBM 14" in the middle? the number there indicates the factory it was made in. apparently the code 29 indicated Essex, so this was a different factory. (see https://www.righto.com/2021/01/) https://www.twitch.tv/tubetimeus let's do some more board layout -- this time, i'm cloning an IBM PS/2 model 80 memory card (gee i wonder why) @tubetime Yet Another Weird IBM Package I guess. All part of its early days vertical integration and vendor lock in strategy? @EricCarroll IBM MST. based on an earlier tech they called SLT (solid logic technology) that they developed in the '60s. @tubetime I thought it looked like the SLT package from the IBM 1130 & 370 I had my hands on at one time. Never seen MST before. Thanks! |
