@trixmixtrixitrix So much memory! No one will ever need more!

@tsturm
I wanted one, so badly.
I fantasized about the printer even.

@tsturm My first computer complete with 16K and rubber band to stop it wobbling and crashing.

@mistergenest I can pretty much remember the day I saw a version of this ad in mid-1981. It was like "I SEE THE FUTURE".

Scraped together my pocket money and had a ZX81 shortly thereafter.

@donald_brady The 16K extension was a strong early education in saving your work and thinking about backups.

@tsturm It looks cheap, I guess.

@tsturm My first born.

[timwardcam@c.im]

@tsturm That was before I got involved in the #Cambridge micro industry. I did a lot of work on the ZX83 (the Spectrum was the ZX82 and the QL was the ZX83, at least as far as the numbers printed on the custom chips were concerned).

@tsturm
This is how it all started for me.

@tsturm
It is about in the middle between the first freely programmable computer (Zuse Z1, Patents date 05/1936, prototypes older) and today!
