Default Re: Zx81

I still can't believe all the time I spent writing machine code, typing it in as hex, saving it, then running it and it crashing and having to load it back in from tape again, modify, try again. A 16K program took about 20 minutes to load! The worst thing was there was no way to verify, and often it would wait until the end of the recording before deciding there had been a read error somewhere and crashing. But I persevered. I managed to write the first level of the arcade game Scramble. A lot of work.

For some while now I've had an ongoing off/on project of writing a full screen, full feature version of Space Invaders for the 1K ZX81 (I use an emulator these days for reasons stated above). Haven't managed it yet. It's nice to have an unattained goal. I was very fond of my ZX81.
