Here's what I have, but this was 2008/2009 so things will probably have changed, and some of the links may now be dead:
The chip was ST2205U from sitronix

One brand with the right chip at the time was Coby.
"coby keyring project, 6MHz 6502-like processor in a small battery powered LCD display usb-slave device."
A possible other match was sold as
Yuraku Photo 1.5" Digital Photoframe Keyring
"So for a tenner you get a battery powered 6502 computer with colour lcd display and a usb interface, in a nice consumer case"

A google search for one specific model

http://picframe.spritesserver.nl/wiki/i ... ch_chipset we see a note to the effect that the ones with a driver CD are a good bet. One type of wrong kit is based on "AX203 basically a souped up 8051" "suspiciously similar to the CPF5102" and presents itself as a CDROM perhaps containing "DPFMate.exe"
Long comment thread here
"Sprites mods: Use a cheap digital photoframe as a second display for your PC - Result"

The hack, at one time, demands a device bigger than 1M flash
There's a project wiki at
http://picframe.spritesserver.nl/wiki/i ... /Main_PageThe hardware we're looking for should show up as
Bus 002 Device 002: ID 1403:0001 Sitronix Digital Photo Frame
which just might be (as of jan 2009) Yuraku 1.5" digital photo-frame
This one from amazon comes with cdrom and may be the right stuff
