Well, my EPROM burner from mcumall arrived, and I'm now got all the hardware bits ready to burn a cartridge for my old Atari 2600. Now all I need to do is finish the programming. I worked on it a bit last weekend, added page flipping and worked on getting the user interface better. In the process, the display itself has gotten a bit crufty, I hastily put in some calculations that added some blank lines, I haven't quite gotten the plugboard interface in, and sound. But a good productive afternoon should tidy up all those bits.
This is the silliest project I think I've ever done. But still, a good excuse to get an eprom programmer.
