I want to build a HP type font/rom cartridge. I know there was a rag article on building your own memory, was there one about cartridges ? I could take and rip one open, but if there's something in there I can't easily buy to make my own, there isn't much sense. al -- Al.

I had one of the early ones open. Four EPROMs and a handful of TTL chips that appeared to be control and bus buffering. They're making them harder to open these days, so I don't know what's in the current ones. -- And the bean-counter replied, | Henry Spencer @ U of Toronto Zoology "beans are more important". | henry@zoo.toronto.edu utzoo!henry
