I've been working on a project over the summer to create a modern microcomputer that has a vintage feel.
I think I've hit on an interesting combination of chips, the Parallax Propeller (acting as the Video/Audio/I/O chip) and the Micromite (A PIC32 chip running MMBASIC and onboard editor).

I figure that there are probably a lot of people who have dabbled with the Propeller since it's been around for a while,
so I've created an Instructable (http://www.instructables.com/id/Building-your-own-Micromite-Companion-Minicomputer/) to build your own.

So far here's that we've been able to accomplished with this project after 4 months of developement.

GBASIC/QBASIC compatible BASIC
54K Free Memory
32 sprites and tiles
Multiple Video Modes

8030 Micromite Companion Mode
4050 Commodore/Atari Style Retrotext Mode
12896 Fat Pixel Mode
256192 64 color sprite/tile mode.


Here's a thread on the project as it developed.

Its interesting to have a middle of the road option, some what between using real chips such as pulls or "new old stock", FPGA re-implementations and FAT software emulation on beefy intel chips....

There's a lot of Z80/68000 implementations out there. I'd suggest looking into them too.
