OLD-COMPUTERS.COM : The Museum

Mitch 74 reports:

I owned a PC-1 Commodore for a long time. It featured:
- a 8088 Intel CPU at 4.77 MHz;
- an empty socket for an optional 8087;
- a single 5"25 DD floppy drive;
- 512 Kb of RAM that could be extended to 640 Kb with 4 150 ns memory chips;
- an expansion slot that allowed connection of an extra module able to host 8-bit ISA cards;
- a proprietary socket to connect an extra 5"25 DD floppy drive or a 3"5 DD disk drive, a 25-pin 9600 bauds COM1 port, and an LPT1 port;
- the video card was Hercules-compatible, and able to emulate CGA when using a small driver, I don't know if the output was actually in colour though;
- no sound (no beeper), but a proprietary mouse port was present;
- an 88 key keyboard;
- no mouse;
- BIOS was 32k, multilanguage, no user settings;
- provided with MS-DOS 3.20.
