I was programming NOVRAMs on my trusty old 486DX2-75 under DOS 6.22 today myself. I do use a new Atom system with a USB to serial converter for programming AVRs, however.
Obsolescence? I fear nothing.
After all, the system I was programming chips for today is my new built from scratch 8085:

The permanent version is much farther along than the site shows. The main circuit card is complete (tested the last bits, user I/O ports, today) and I’m about to cut metal on the enclosure. Time for a website update, I guess.
Cool website, I like what you’re doing. I cut my teeth on the 8080 and MC68000 but I haven’t worked with anything but PIC micros for a decade now.
I’m going to keep an eye on your site for updates.
