2008 - Driver Updates
---------------------
(most of the informations are taken from http://www.zimmers.net/cbmpics/ )
[CBM systems which belong to this driver]
* Commodore 65 (1989)
Also known as C64 DX at early stages of the project. It was cancelled
around 1990-1991. Only few units survive (they were sold after Commodore
liquidation in 1994).
CPU: CSG 4510 (3.54 MHz)
RAM: 128 kilobytes, expandable to 8 megabytes
ROM: 128 kilobytes
Video: CSG 4569 "VIC-III" (6 Video modes; Resolutions from 320x200 to
1280x400; 80 columns text; Palette of 4096 colors)
Sound: CSG 8580 "SID" x2 (6 voice stereo synthesizer/digital sound
capabilities)
Ports: CSG 4510 (2 Joystick/Mouse ports; CBM Serial port; CBM 'USER'
port; CBM Monitor port; Power and reset switches; C65 bus drive
port; RGBI video port; 2 RCA audio ports; RAM expansion port; C65
expansion port)
Keyboard: Full-sized 77 key QWERTY (12 programmable function keys;
4 direction cursor-pad)
Additional Hardware: Built in 3.5" DD disk drive (1581 compatible)
Miscellaneous: Partially implemented Commodore 64 emulation
[Notes]
The datasette port was removed here. C65 supports an additional "dumb"
drive externally. It also features, in addition to the standard CBM
bus serial (available in all modes), a Fast and a Burst serial bus
(both available in C65 mode only)
