I'm actually looking to borrow the UPD1771C-006 chip out of a NEC APC at some point; it is actually a weird, sound/speech provider microcontroller with mask rom, used for making the system beeps/melodies on the NEC APC, and is important to get dumped for emulation purposes. It can be dumped non-destructively (it has a test mode where it spits out its rom contents if you hold two pins in a particular configuration).

Following up on two things. I have a NEC machine (nicknamed the "Herniator" because of it's weight) that came to me via Kyle that is a PC near compatible that has 8 inch drives. Runs MS-DOS. It at least, I'd say, is a little interesting. I don't know of many other MS-DOS compatible machines that ran off 8 inch floppy. That would be a NEC APC, which is a fantastic machine. It was aimed squarely at the CAD market, and had very high-end graphics capabilities for the time, built around a NEC 7220 graphics controller.
I have one of those machines, but it has an as-yet-undiagnosed hardware problem. I hope to get it running someday.
And in theme with Herb's kerosene powered fan, I actually own a gasoline powered clothes iron. Looks like a regular small iron but is gasoline powered. Seriously. Neat!
