For people on the go. Radio Shack TRS-80 Model 100 Portable Computer (1983). For a tiny computer this thing has a great keyboard and is loaded with ports. Even has a built in modem. #TRS80 #RadioShack #Tandy

Just posted a new video on YouTube: a faulty riveted via on a PCB from the early 1970s. It's on the digit driver PCB of a Venner TSA240 Digital Timer, and makes one display digit go blank when the instrument is cold: youtu.be/nPisWbrj77o

We thought it was long overdue for us to celebrate the Commodore Pet. Our latest display at the Centre includes the chance to load some software in the old fashioned way, via a restored disk drive, you can look at our not often seen SuperPet too :) #Commodore #VintageComputing

The Matthew is back on the slipway at Underfall Yard for its annual check-up ⚓️ Be sure to come and take a closer look in the coming days. We think this angle really suits her! #matthewofbristol #bristol #boatlife

Tek 7603 working with three analog plug-ins. Still needs a bit of adjustment to get the focus really sharp, and to move the readout down the CRT a bit -- the upper read-out is off the screen @vintageTek

Had a look at the 7D01/DF1 logic analyser today. Had no vertical deflection at all, horizontal OK. -4.8V and -2V power rails OK. Traced signals all over the place, wiggled connectors, and we have a display! This must be what the Matrix looked like in 1976 @vintageTek
