Emulation

[N36fSL3A]

Hi, I've finished a Chip-8 virtual machine (which was boring, unfun, and overly simple), and I lost the source code to it and the NES emulator I was working on (next time I put it on GitHub D:<). I'm starting to get bored of the NES anyhow, and my next objective is to do an Apple ][ Emulator or any personal computer really. I'd like to know of a fairly simple personal computer from the 70s or 80s that I should attempt on emulating.

Just something with simple graphics, and something with fairly common hardware so it's code can be reused to some extent.

Thanks.

Any more ideas?

EDIT 2:

I just realized this does not meet your requirements of being reusable or having simple graphics.

It's fine. I'll look into it.

Still open to suggestions.

If you think the NES was simple and whatnot. Lets throw some networking in here! Create server software for virtual NES systems. At least 3 NES's. Have a telnet control panel where P1 and P2 vote on the control buttons such as "Reset", "power on" and "Switch ROM". The clients are the players. They shall play multiplayer games without having to sit in the same room on the same computer. FCEUX has something like this. It's totally reusable and has NES graphics!

Wait, I did not say nor mean to imply the NES was simple. I said the Chip-8 was bland and simple.
