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!
Technical
The 8bit Printer Port is implemented 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 RS232 Z8470 (Z80 DART) Channel A Data (R/W) FADDh Amstrad RS232 Z8470 (Z80 DART) Channel A Control/Status (R/W) FADEh Amstrad RS232 Z8470 (Z80 DART) Channel B Data (R/W) FADFh Amstrad RS232 Z8470 (Z80 DART) Channel B Control/Status (R/W) FBDCh Amstrad RS232 8253 Baudrate Timer 0 Channel A TX Clock (R/W) FBDDh Amstrad RS232 8253 Baudrate Timer 1 Channel A RX Clock (R/W) FBDEh Amstrad RS232 8253 Baudrate Timer 2 Channel B RX/TX Clock (R/W) FBDFh Amstrad RS232 8253 Baudrate Timer 0-2 Control Registers (W)
