Sinclair ZX80/ZX81 and Jupiter Ace Emulation

Sinclair ZX80/ZX81 and Jupiter Ace
I have been discussing ZX80/81 Emulation with mob-i-l, of which, various solutions are available (edited transcript below). Although the Hardware was quite limited (no Colour for instance) these two machines were instrumental in kick-starting the UK/Europe Personal Computer boom in the early 80s due to their extraordinarily cheap prices. Released in the year of their suffix, kit or Pre Built versions of the ZX80 retailed at £70/£100 and the ZX81 £50/£70 respectively, as a comparison my first Hardware purchase (a Commodore VIC-20) cost £225 in 1981 which I promptly traded for the far more capable Atari 400 at £350! I have also attached a Jupiter Ace Emulator from his previous posting, another UK curiosity due to the use of Forth as its primary language rather than the usual Basic, never selling in the volumes of the ZX80/ZX81 (only 8000 were produced) this has made it very collectable in the Retro market.


Now I reinstalled it after installing Raspbian with NOOBS. I wrote down how I did this to help others getting started with ZX80- and ZX81-emulation. I had to do this before make of sz81:
sudo apt-get install libsdl1.2-dev

sz81: http://sz81.sourceforge.net/

There is a new ZX81-emulator that can run in xterm in Raspbian if you get the new xterm and compile it with Sixel-graphics. (I think it would be good if the standard xterm in Raspbian had Sixel-graphics support built-in.)

Instructions on how to install the emulator in Raspbian on Raspberry Pi is here:

It compiled without warnings on RPi.
