I built my SBC without any prior experience. You pretty much just have to connect all the adress and data lines, and then figure out the chip selection logic. I used an MC68B50 for the UART, which can still be found very cheaply on eBay.

Huh. I guess it's worth a shot, then... I'll have to look into using a MAX232 for connecting it to my terminal, as well (I do, in fact, have a terminal: A Z19, in fact).

Might as well build a Z80 system while I'm at it. And Zilog's UARTs are quite nice, or so I've heard.

One thing I'd recommend is to try to find some 5V erasable EEPROMs, so you can reprogram it in-system wthout having to transfer it over to a dedicated (and expensive) programmer.

I went with a 12V-EEPROM at the time, so I had to write my own emulator to speed up my development cycles :)
