Panda Electronics Communications Interface Unit
Dual RS232 with 8bit Printer Port. Driver ROM from Panda Electronics Ltd.
Known and Unknown Stuff
The ROM image from Panda Electronics is found on various webpages. However, there is nothing known about the hardware.
There are no known descriptions, photos, or adverts for the actual hardware.
So far, it is unknown if "Panda Hardware" does exists at all (possibly, Panda only made the software, and the corresponding hardware was produced or distributed by a different company - a possible candidate might be Timatic Systems whom did offer a "dual rs232 with 8bit centronics")
Please add info if you know where the ROM image came from!
