Commodore PC compatible systems

The Commodore PC - 10 to PC -60 is a series of IBM-compatible PCs from Commodore, which was sold in 1985 to the mid-1990s. They were constructed in the Brunswick Development Department and partially assembled in the local Endfertigungswerk.

This computer family to Commodore delivered a few years a head-to -head with IBM for market leadership in the PC sector in Germany, typically lead changes from month to month. The climax was reached it that after the turn of all the offices of the Deutsche Reichsbahn in East Germany were equipped with Commodore PCs.

PC-10 and PC -20

These computers were cheap alternatives to the IBM - PC and were produced from 1985. The PC-10 was offered mid-1985 at a price of DM 4,950 excluding VAT. They were characterized by a good quality, robustness, compatibility and expandability. They were equipped with an Intel 8088 processor that was clocked as in most early PCs at 4.77 MHz and could be extended with a mathematical co-processor Intel 8087; to, 256 KB RAM (expandable to 640 KB ), two 5 ¼ " floppy disk drives each with 360 KB capacity and, in PC -20, a 10 -MB hard drive. further the computer could due to the five existing XT- bus slots well be extended., the so-called AGA graphics Commodore PCs could display both CGA and MDA and Hercules graphics modes, which the vast majority of that PC programs was covered ( EGA graphics cards were in 1985 still very expensive and were therefore rarely an absolute requirement ). especially in Europe, these models sold very well.

Since the motherboard in Braunschweig was developed on its own CBM -8000 computers with the help of their own 8000 graphics board, thus only a certain platinum size was manageable, the board had to be split into two halves, which were plugged together.

While most former personal computers, including the IBM models, the keyboard controller is the only interface component directly on the motherboard ( " motherboard" ), was the board of Commodore computers housed next to the controller for two floppy disk drives, a Centronics interface and an RS232 interface. For two to three slots were saved because almost all PCs these components is required anyway.

PC -30

The PC -30 was a version of the PC -20 with 20 -MB hard drive.

PC-10 II, PC - 20 II

Practically the same equipment, but with a revised, integrated motherboard (Combined Board) and the PC -20 II with 20 -MB hard drive, no PC -30 more.

PC-1

The answer of Commodore on the PC1 of Atari: A PC-10 in an ultra compact body with a floppy drive, a hard drive and / or two ISA slots, you needed the second, the same size housing with an external cable connection. Not very successful, and soon discontinued.

PC-10 III -20 III PC

The same architecture, only much more compact. The motherboard housed next to the then usual and already above mentioned components, the controller for two MFM drives, the Hercules graphics card and a ( Amiga ) mouse interface. The clock rate could be doubled using a hotkey or via a program on 9.54 MHz; also an increase to 7.16 MHz was possible.

PC - 40 and PC -70

Here is IBM -compatible PC with 286, 386 and 486ern, from PC -60 in the tower case and with a purchased motherboard that do not have feature.

Still later were only complete other brands, mostly from Taiwan, as Commodore PCs sold. For them, the yield was given the tighter market and the growing competition from discounters such as Vobis and Escom not as high as before.

" - And a 5 ¼" In Germany, inter alia, include models from the Commodore PC with a 3 ½ drive were sold.
