He has a board at his class that is essentially a superset of the DS80C320, namely the DS89C430. It's a very fast flash-based version of the '320 with the ability to map its 1k-Byte XRAM in to both external and code space. He can program a monitor like Ultramon51 (that's what I use from time to time) which can be loaded into the bottom half of the '430's 16k-Byte on-chip code space via the serial port, and then serve to load a program into the properly mapped XRAM. The monitor will allow him to enter, assemble, disassemble, and debug small bits of code, and, when he's ready, he can use a PC-based cross-compiler, or cross-assembler along with the MAXIM-provided programming software that uses the serial port, to handle bigger programs and data.

There's no need for EEPROM, no need for a programmer. I, too, have a programmer or three, yet much prefer this sort of approach. I think you would, too.
