Long awaited (mostly from me) now here they are: pictures of my (last, yet) Commodore C900. Taken as of 31 Oct 2001 with an elder Olympus Camedia (1.3 MPixels). That C900 is a reconfigured model; it does not have 4 serial ports, only 3 are left. Instead it has a nice graphical interface for a special monitor-tube; the screen then has CGA capabilities and text mode is graphic mode black text on white background. Very fine working with that configuration. Oh yes, you can use text mode interface as well...
Pic 3: C900 rear side. From left:
upper line: power interface (220V/50Hz), Papst fan;
middle line: TTL-monitor interface, RS232 #3 interface, CGA-Monitor interface (DIN 5-pin);
lower line: printer interface, RS232 #2 interface, RS232 #1 interface, Reset key, Commodore user port.
