I have a Sinclair Programmable, still works.

Where my MK14 went, I do not know.

$50SAT is Silent but probably still working.

I'm trying to resist the urge to download the emulator...

It even had subroutines.

And guess what was the ultimate challenge...

Writing a Clock, Lol.

And surprisingly it kept pretty good time.

OMG Phil,

I used one of those (or an almost identical model) when I was a student at Glenroy Technical School.. I was one of the privileged kids allowed to `play' with it.

I was a student there from 1971-1975 and the program was done on punch cards just as shown in the video.. In fact I could almost say that was the very machine I used.

It has all the look and feel of it. The punch card on the top right and the string of `nixie tubes' for the display.

As Glenroy Tech was a lowly working class area school, the punch cards were not handed out willingly, I had to ask the teachers for permission and offer a good reason why I needed to use one.. Needless to say we checked every line carefully.

Thank you for the nostalgic trip back in time when I was Young and Innocent.

Kind Regards,

Mick

Lol Mick,

Did they make you reuse yours too?

Carefully put the little squats back in with a tiny bit of tape?

For some reason 90 odd lines rings a bell.

And things like UJ, FJ, MJ....
Rang a bell when I looked at the emulator docs.

Hi Phil,

I have some memory of taping the holes but not of taping the little rectangle punch tabs themselves back in, we may have used OPAQUE tape.. But then I was exposed to a similar system at GMH as an apprentice (starting 1976) with a NC Milling Machine, so I may be confusing the two memories there.

Too many beers ago for those brain cells to be still working perfectly for me.

Kind Regards,

Mick
