As some of you know, for the last few weeks I have been researching the first commercial transistor computer, Metrovick 950 (and it is based on the first transistor computer ever, making things even more interesting).
I wrote the emulator for the computer, a simple assembler, and a handful of toys to get a grasp of the extremely frugal digital computing. What does it feel like to use a machine built on 250 transistors, operating at 200 operations per second or so? Can it display anime girls? (It IS a very important feature of any computer!!!) Is there even a point in such a computer?
I was hoping to write a long post about it, but my fatigue gave birth to a migraine (or the other way around), so the best I can do is to start a thread 🧵 It can be of interest for people who love computer history, want to know more about small computers of the 50's like the Bendix G-15 Usagi Electric has, and those who are thinking of building bit-serial computers.

@nina_kali_nina Your emulator was shared on Lobsters:

@nina_kali_nina Your emulator was shared on Lobsters:
@amoroso thanks for sharing the link! I believe it is a very niche project, but if other people like it, I'm happy

@nina_kali_nina You're welcome. I think being niche is part of why it's interesting: emulators of very early systems are rare.

@amoroso indeed! I know that mine is not entirely accurate (I mentioned the likely differences from the real machine in `errata.md`), mostly due to the lack of good documentation and real software for the computer. I hope to access the company archives one day to find more info about it and recreate the machine's behaviour faithfully.

@nina_kali_nina And now the emulator is featured on Hackaday and OS News:

Per il piano casa UE servono 150 miliardi all’anno. E una stretta sugli alloggi brevi (ma non sarà un divieto)

Il commissario UE Dan Jørgensen ha presentato a Strasburgo il piano della Commissione europea per affrontare la crisi abitativa. Prevista una revisione delle regole sugli aiuti di Stato e una semplificazione delle procedure per la costruzione di nuovi alloggi

@steek_hutzee 29 marzo 2022, dunque dopo essere stati invasi e col rischio che le truppe russe arrivassero a Kiev. Ma perché vergognarsi?
Se ce l'avessi lungo 3 cm stimerei Rocco Siffredi
Se la mia donna fosse 1.40 m x 140 Kili invidierei Flavio Briatore
Se alle medie mi avessero bullizzato oggi avrei voluto essere un bullo come Trump e Putin
Nessuno ti giudica ma permettimi di non essere come te

This is NOT an invitation to tell me your opinions about my weight, willpower, or to criticize my choice to go on this medication. Thank you.

I'm on a glp-1 medication. It's... pretty wild.
I would describe myself as having a malfunctioning appetite: I am *always* ravenously hungry normally, which is one of the reasons I am always cutting up and eating apple slices and baby carrots at my desk, so that I don't overdo it. It's very exhausting to manage.
For the first time in decades I'm experiencing the sensation of fullness and not constantly thinking about food. Weight is dropping off fast, maybe even *too* fast. Wild.
