Also got one of those UV eeprom erasers, just in case I ever go that route. (What is the advantage of the eproms with the UV window over the one I got anyway?)
The 27C series of UV-erasable EPROMs are generally faster than the 28C series of EEPROMs, with access times down to 55ns in some cases. For example, I use
this EPROM in my POC machines. Also available are
one-time programmable (OTP) ROMs, with access times as low as 45ns. I've tested this part in my POC V1.1 unit. It will boot at 15 MHz.

Assuming my lab is well stocked with passives, LEDs, seven segs, breadboard supplies, a regulated PSU, and decent test gear, and a few options to connect a UART to a PC, is this all I need to get something going? (besides actual firmware to put in the ROM of course)
A good soldering iron and some patience, and you're on your way.
