Parallel ASCII keyboards

Looking for thoughts on which machines used parallel ASCII keyboards... I've got a couple of working machines here that used such a keyboard based around the AY-3-4592 chip, but only one keyboard to go between them. The interface between the keyboard and system is just 8 data lines and a strobe though, all at TTL, so presumably any old keyboard that outputs ASCII data could be made to work. Ideally I'd like to find a real basket-case of a system that could provide me with a donor keyboard. I'm not 100% happy with that, but providing the rest doesn't go in the bin (such that it might be useful to someone at a later date) and it's not something that's ultra-rare, it seems a reasonable thing to do in order to complete an otherwise-pristine system. Knowing which systems to look out for would be a start. Nascom, maybe? I think RML 380Z's are probably parallel ASCII too, but their keyboards are already rare as hen's teeth so I wouldn't be happy with that... cheers Jules -- (\__/) (='.'=) This is Bunny.
