I've got a Verifone TRANZ 380 credit card terminal here that's been long out of service. It's kind of interesting--has a Z180 type CPU, what looks to be 32K of memory, a low-speed modem and a VFD 7 segment display. Complete with AC adapter.
Will ship for postage (USPS Medium FRB will work). If no interest, it goes on the e-cycle pile.

Hmm... A VFD you say... sounds interesting.

Is there a separate ROM, or is this some Z180 variant with integral ROM?

Found a few details online -- looks like it could make an interesting project -- declaring interest. I'll send you a PM, Chuck.

@NeXT This is right up your alley!

I've found lots of them over the years, most of the ones that look like that are plain Z-80 with a big (32K?) socketed EPROM and a 20(?)-character VFD display. I've been meaning to hack on one of them "someday", you know how that goes. Getting a good disassembler working was one of the many things blocking me. If you want to play with some random Z-80 thing, you could do worse.

Later bigger ones with a Z-180 often have nice big 128K byte SOIC SRAMs.

Got a taker for this one, thanks. Yeah, the RAM in this one is 128KB one. Interesting big chips in it--Z180, SIO, PIO, CTC and a TDK 212 modem chip. Oh, and an OKI clock chip. Battery is a soldered-in coin cell, which probably means that these things are tossed when it runs out. I was surprised that the one in this terminal was still keeping the right time after sitting on the shelf, unpowered for 10+ years. 2-board design.
