2008 - Driver Updates
---------------------
(most of the informations are taken from http://www.zimmers.net/cbmpics/ )
(also, check
http://www.6502.org/users/andre/petindex/local/cbm-model-list.1.0.txt
for a more comprehensive list of models)
[CBM systems which belong to this driver]
* Commodore PET 2001 (1977) - board design 1
* PET 2001 Series / CBM 20XX Series (1979) - board design 2, upgraded ROMs
PET 2001, the first of the series came initially with a calculator style
keyboard, later changed to a larger and better full-stroke one (actually
it was available in two versions: Businness and Home Computer, the latter
also containing graphics on the keys). Plenty of models were released in
this series, depending on the RAM size, the keyboard type and the screen
dimension (see below).
CPU: MOS 6502 (1 MHz)
RAM: 4K and 8K early models (Expandable to 32k addressable, more banked);
8K, 16K, 32K later models (Expandable again to larger RAM config)
ROM: 18 kilobytes early models; 20 kilobytes later ones
Video: MOS Technology 6545 CRTC (9" Monochrome display; 40 columns x 25
rows )
Sound: None ine arlier models; Piezo electronic speaker later ones(One
square wave voice; Three octaves)
Ports: MOS 6520 PIA, MOS 6522 VIA (IEEE-488 edge-connector Port; 2
Commodore Datasette ports; 'EXPANSION' port; CBM parallel
programmable "User" port
Keyboard: "Calculator" 69 key QWERTY in early models and Full 69 keys QWERTY
in later ones (16 key numeric keypad!; 4 direction 2-key cursor-pad )
Additional hardware: Datasette

G&W = Green and White Screen
Calculator Keyboard models also had a built-in datasette
Home Computer Keyboard also features graphics on keys
(*) Models 2001B-XX & 2001-XXB are the same. Same applies to 2001N-XX &
2001-XXN
(**) Also confirmed with Black Trim and 9" Screen G&W
(***) Also confirmed with Black Trim and 9" Screen B&W
* Commodore CBM 3008 / 3016 / 3032 (1979) - board design 2, upgraded ROMs
In Europe, Philips was already selling a machine called PET, so they
forced Commodore to change name. The result was the CBM 30XX Series, where
XX is equal to the RAM size. These were basically PET models with 9" Screen
and upgraded ROMs. There also existed a German CBM 3001, which was a PET
2001, B or N. Notice that these systems used to boot
CPU: MOS 6502 (1MHz)
RAM: 8K, 16k, and 32k models (Expandable to even more banked memory)
ROM: 20 Kilobytes
Video: MOS Technology 6545 CRTC (9" Monochrome display; 40 columns x 25 rows)
Sound: Piezo electronic speaker (One square wave voice; Three octaves)
Ports: MOS 6520 PIA, MOS 6522 VIA (IEEE-488 edge-connector Port; 2 Commodore
Datasette ports; 'EXPANSION' port; CBM parallel programmable "User" port)
Keyboard: Full 69 key QWERTY (16 key numeric keypad!; 4 direction 2-key cursor-pad)
* Commodore PET 40XX / CBM 40XX (1980) - board design 2, BASIC 4, 9" Screen
* Commodore PET 40XX / CBM 40XX (1981) - board design 3, BASIC 4, 12" Screen
While the 40XX machines (again 4008, 4016, 4032) coming with design 2 were
quite similar to the previous ones (except for the new BASIC version), the
machines with design 3 were quite different: there was CRTC support, it was
possible to upgrade to 80 cols and a piezo beeper.
CPU: MOS 6502 (1 MHz)
RAM: 8K, 16k, and 32k models (Expandable to even more banked memory)

columns x 25 rows)

Ports: MOS 6520 PIA, MOS 6522 VIA (IEEE-488 edge-connector Port; 2 Commodore
Datasette ports; 'EXPANSION' port; CBM parallel programmable "User" port)
Keyboard: Full 69 key QWERTY (16 key numeric keypad!; 4 direction 2-key cursor-pad)
* Commodore PET 8032 / CBM 8032 (1981) - board design 3, BASIC 4, 12" Screen
Again, 80 columns screen and piezo beeper; BASIC 4 has a 80 columns editor
ROM. It was possible to expand it to a 8096.
CPU: MOS 6502 (1 MHz)
RAM: 32k standard (Expandable to even more banked memory)
ROM: 20 Kilobytes
Video: MOS Technology 6545 CRTC (12" Monochrome displays; 80 columns x 25 rows)
Sound: Piezo electronic speaker (One square wave voice; Three octaves)
Ports: MOS 6520 PIA, MOS 6522 VIA (IEEE-488 edge-connector Port; 2 Commodore
Datasette ports; 'EXPANSION' port; CBM parallel programmable "User" port)
Keyboard: Full 73 key QWERTY (11 key numeric keypad!; 4 direction 2-key cursor-pad)
* Commodore PET 8032-SK / CBM 8032-SK - board design 3 & 4, BASIC 4, 12" Screen
New (smaller) case with detachable keyboard (SK=Separate Keyboard). Board
with design 3 didn't fit very well the new case and required extra cables.
It was possible to expand it to a 8096-SK.
CPU: MOS 6502 (1 MHz)
RAM: 32k standard (8096 expanded to 96k, 64k is banked memory)
ROM: 20 Kilobytes
Video: MOS Technology 6545 CRTC (12" Monochrome display; 80 columns x 25 rows)

Ports: MOS 6520 PIA, MOS 6522 VIA (IEEE-488 square-connector Port; 2 Commodore
Datasette ports; 'EXPANSION' port; CBM parallel programmable "User" port)
Keyboard: Full 73 key QWERTY (11 key numeric keypad!; 4 direction 2-key cursor-pad)
* Commodore CBM 200 Series (198?)
Rebadged CMB 80XX models: the CBM 200 was basically a CBM 8032-SK and the
CBM 220 was a CBM 8096-SK.
* Commodore Super PET / MMF9000 (1981) - BASIC 4, 12" Screen
Based on PET 8032. Sold in Germany as MMF (MicroMainFrame) 9000. Machines
sold in Italy had 134kB of RAM.
CPU: MOS Technology 6502 & 6809 (1 MHz clock speeds)
RAM: 96 kilobytes (64K was contained on an expansion board above the motherboard;
Early SP9000 models had two boards above the motherboard; Some models also
had 3 or more switches)
ROM: 48 kilobytes
Video: MOS Technology 6545 CRTC (12" Monochrome display; 80 columns x 25 rows;
3+ character sets, 256 characters each)
Sound: Piezo electronic speaker (One square wave voice; Three octaves)
Ports: 6551 ACIA, MOS 6520 PIA, MOS 6522 VIA (IEEE-488 edge-connector Port; 2
Commodore Datasette ports; 'EXPANSION' port; RS232 Internal port; CBM
parallel programmable "User" port; Memory and Processor selection switches)
Keyboard: Full-sized 73 key QWERTY (Multi-Font 62 key keyboard; APL Symbols on
the front of the keys; 11 key numeric keypad; Editor functions on the front
of the keys; 2-key 4-direction cursor-pad)
* Commodore CBM SP9000
Similar to Super PET. Dual uP 6502/6809, 96kB RAM, business keyboard.
* Commodore PET 8296 / CBM 8296 (1984) - BASIC 4, 12" Screen
Shipped with 128k RAM and separate keyboard, it is a complete redesign of the
PET universal board. It fits into the separate keyboard case, and directly holds
128k RAM, of which 96k can be used as in the 8096. In addition, using "user
jumpers" on the motherboard, the ROM can be completely switched off to access
the RAM "under the ROM", so that the complete 128k RAM are accessible. The "user
jumpers" could be set to connect to the userport, so this could even be done
under program control.
CPU: MOS 6502 (1 MHz)
RAM: 160K (32k standard)
ROM: 24 Kilobytes
Video: MOS Technology 6545 CRTC (12" Monochrome displays; 80 columns x 25 rows)
Sound: Piezo electronic speaker (One square wave voice; Three octaves)
Ports: MOS 6520 PIA, MOS 6522 VIA (IEEE-488 Port; Commodore Datasette port;
'EXPANSION' port; CBM parallel programmable "User" port)
Keyboard: Full 73 key QWERTY (11 key numeric keypad!; 4 direction 2-key cursor-pad)

more informations
* Commodore PET 8296D / CBM 8296D (1984) - BASIC 4, 12" Screen
It was a 8296 with built-in 8250-LP disk drive.
* Commodore CBM 8296GD
Mentioned at http://www.commodore.ca/products/pet/commodore_pet.htm#Commodore%20PET%20Chronology
as a 8296 with a high resolution graphics board and drive. No other info available.
[Other models]

marketing campaign in US schools
* MDS 6500 Modified 2001N-32 with matching 2040 drive. 500 made.

[TO DO]
* Verify if pre-CRTC models had differences between NTSC & PAL systems.
If no differences arise we can merge back the following sets:
+ cbm30 (same as pet2001n) & cbm30b (same as pet2001b)
+ cbm40o (same as pet40on) & cbm40ob (same as pet40ob)
* Emulate SuperPET / SP9000 / MMF9000 and their differences
* Emulate CBM 8296 & 8296D (basically only a placeholder now)
* Add proper tape support
* Add sound support, for systems which had it
* Find out answers to the following details:
+ Did BASIC 2 also come as upgrade ROMs for PET 2001 with Static Board? If
this is the case, we need to support the splitted versions of the ROMs as
an alternative BIOS to pet2001.
+ Did final PET 40XX & CBM 40XX with 40 Columns & CRTC support had business or
normal keyboards?
* Find confirmation about some models (which I don't believe ever existed,
but...):
+ were there PET 2001-16k & PET 2001-32k with Calculator type keyboard?
+ were there CBM 20XX in Europe?
+ what about the following unrealistic RAM configurations: 4004? 8008? 8016?
8064?
+ did a CBM 210 exist?
