#fischertechnikcomputing — Public Fediverse posts

I've replaced the BD136 transistor on the #FischertechnikComputing PC/XT/AT interface with a brand new one I bought today at the local electronics store (yes, they still do exist!). Can you guess which one it is (the transistor, not the store)?

I seem to recall we have an antique laptop with a parallel port somewhere so I can test this thing. Otherwise, I'm sure I know someone who might be able to help. 🙂

EDIT: Clarified question in the first paragraph

It’s alive! For the most part, that is. Turns out one half of one H-bridge in the interface is broken: M3 won’t turn right. Let’s check the transistors.

Oh, bummer. This axle is 15 mm too short! I wonder if I can still get a replacement. I will try to continue the build nonetheless. #fischertechnik #FischertechnikComputing

Ok then. Here we go! #FischertechnikComputing

Speaking of which: The #FischertechnikComputing "Training Robot" was my favorite model. It was very expensive and I never got one. This is one of my childhood dreams I've kept over the years. They're quite rare today and difficult to find on #eBay or #Kleinanzeigen.

Fourty years ago (that would be 1985) #Fischertechnik released a four of construction sets as part of their #FischertechnikComputing series. Here's a scan of the original brochure (in German, no OCR): https://docs.fischertechnikclub.nl/info2/1989.pdf

I think it must have been Christmas 1989 when I got model no. 30554 (pages 4/5). It has survived until today (despite of many years in the attic).
