Hardware design

[inx]

Hello all,

I'm probably barking up the wrong tree here, but does anyone here have any hardware design experience (specifically, NTSC video signalling)? I'm working on a simple computer (80s-ish) as a hobby electronics project. My first impulse was to use a 6502 with a display controller IC, before I found out it's ridiculously difficult to find a 6502 any more, and even harder to find a display controller for something like this.
So now I've got most of the design down using a Z80, but I can't figure out the whole display controller thing. I'm thinking about just using shift registers and another Z80 as a display controller with the clock interleaved with the first to avoid bus contention. Basically, I'm just looking for pointers on where to further my research into this.
Anyway, I understand if nobody can help, but I just figured if there's anywhere decent to ask left, it'd be here. lol

I don't know anything, but the guys on the forums at http://6502.org have quite a lot of experience. In the hardware subforum there are a number of threads about video hardware and how to make it yourself.

Thank you very much. Exactly the kind of pointer I was looking for.
