I loved mine and learned BASIC with it. Unfortunately the RAM expansion had this undesirable auto-reset feature. If I only had known that the defect RAM expansion could be fixed with a bit of tape...


I recently replaced a broken DRAM chip on one of those! https://blog.qiqitori.com/2022/02/testing-a-zx81-ram-pack-wi... (this is more about finding which one is the broken one than about the actual replacement)

The one I had doesn't seem very wobbly though. Maybe there is some variation between production runs etc.?


Ah yes, the RAM pack wobble. Was common as heck upon the original Sinclair expansion. There was however 3rd party RAM upgrades and those in comparision proved less prone to such wobble and with that regard, I was pretty alright with the one I setteled upon. But such PCB edge connectors were common then, less so these days.


I had the Memopack 16k and it even fitted the "High"Resolution graphics pack on top. But then I also soldered a flat cable to an external keyboard which was much nicer to type on an did not wiggle the whole stack with every key stroke.


Or a bit of blu-tack, in the shape of a runner bean...


Nice reference there! Micro Men really is a great docu-drama, it really feels like it captures the time very well.

As my first computer was a BBC Micro, it really struck a chord. It’s great seeing the specs for the (yet to be built) ARM chip on the board in the Acorn office, and it’s also awesome that Sophie Wilson playing the barmaid too!

For those that haven’t seen it, it’s definitely worth a watch [1]

An absolutely brilliant bit of creative work, indeed.

Nothing else has ever really conveyed that Clive Sinclair wasn't a sort of little professorial boffin the way the British press portrayed him; he was very business-focussed and evidently had quite a presence.

(Common to the almost concurrent misportrayal of John Major as a small, retiring, grey man)


I've heard that he was quite the party animal as well, something which doesn't quite seem to have been covered by the show (albeit some aspects hinted at tangentially).


It's wonderful. I've pretty much watched it to death, but still occasionally have another go.


Mine had the unfortunate 'let out the magic smoke' feature :/ Which fortunately led to the upgrade to an Atari 800 :)
