I have one from Dataman (UK). It seems to take a lot longer to erase
pics than eproms - 30 to 60 secs versus about 10 for most modern
eproms. I don't know if it's still in production. They probably have a
website - shouldn't be too hard to find.

On the subject of flashes, a photo flash WILL temporarily disrupt a
system running code from an eprom (external or on-board), from a
surprisingly long distance away in some cases. The intense light
temporarily disrupts the read amplifiers, causing read errors.
 Moral - cover eprom windows well when exhibiting at shows, or
anywhere that people might be taking pictures :-)
