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 whom did offer a "dual rs232 with 8bit centronics")

Please add info if you know where the ROM image came from!

Technical

The 8bit Printer Port is implemeted via a 8255 PPI chip. The dual RS232 port is compatible with the Amstrad Serial Interface. I/O Ports are:

 F9DCh  Panda PPI Port A - 8bit Printer data
 F9DDh  Panda PPI Port B - 8bit general purpose I/O port
 F9DEh  Panda PPI Port C - Handshake (bit0=Strobe.out, Bit5=Busy.in)
 F9DFh  Panda PPI Control - 8bit Printer data
 FADCh  Amstrad RS323 Z8470 (Z80 DART) Channel A Data             (R/W)
 FADDh  Amstrad RS323 Z8470 (Z80 DART) Channel A Control/Status   (R/W)
 FADEh  Amstrad RS323 Z8470 (Z80 DART) Channel B Data             (R/W)
 FADFh  Amstrad RS323 Z8470 (Z80 DART) Channel B Control/Status   (R/W)
 FBDCh  Amstrad RS323 8253 Baudrate Timer 0 Channel A TX Clock    (R/W)
 FBDDh  Amstrad RS323 8253 Baudrate Timer 1 Channel A RX Clock    (R/W)
 FBDEh  Amstrad RS323 8253 Baudrate Timer 2 Channel B RX/TX Clock (R/W)
 FBDFh  Amstrad RS323 8253 Baudrate Timer 0-2 Control Registers   (W)
