Re: Just use emulation
Hah. I'm currently building (another) processor -- not system -- from discrete HCTTL. This one's by way of being an instructional project for some of the younger guys at work, and it replicates most of an 8080 only in a lot fewer clock cycles. The system is the easy bit.
Emulation programs such as Logisim make this kind of thing very easy these days. I should get around to doing some screen movies and dropping them onto youtube. I expect to get Ron Cain's C up and running on it.
I can't be doing with this modern stuff, where's me pipe?, who's got me slippers? etc...
