An update on my microcontroller-based external serial programmer:
I can program 5V-only chips, in DIP32 form, or PLCC32 with an adapter. The highest baud rate I've been able to make work is 115200, which makes things pretty slow. Further experimentation may show that I could run a higher baudrate and maybe remove most of the `noop` delays in my I/O routines - but that's for another day.
I was thinking of programming 2mbit flash chips with shift registers and an regular arduino and it didn't occur to me to use flashrom as software. When I get around to using them I might just have to spring for a megaduino. Sweet!
