Yer had a ZX81 also for a short while I was oooh about 6!.. Man did that thing know how to crash just when you've got a few lines to go.. Yes sadly I did start tinkering that early.

But on the gaming note.. I think it would be semi possible particularly on the 9400 as the screen is less to update and you can really notice the speed difference.. Plus it's portrait so ready for some classic gaming history.
