characters/

c128.bin@ (link)

390059-01 Commodore 128 character ROM. The first half has the standard Commodore 64 character set, and the second half has the C128 mode character set, which is slightly different. All characters except the lower case m are identical with the Commodore 16 character set. The uppercase/graphics character set is identical with the C64, including the reverse at sign (@) bug, which is missing from the lowercase/uppercase character set.

c16-hungarian.bin

Hungarian Commodore 16 character set made by Novotrade. The capital A and P, the lower-case i and the graphics characters $65 and $67 in the uppercase/graphics bank and $65 in the lowercase/uppercase bank have gone through cosmetic changes. The national characters are present in the lowercase/uppercase bank in positions obtained by pressing the C= key with a letter.

c16-hungarian.readme

Keyboard layout for using the Hungarian Commodore 16 character set. Typed in the ISO 8859-2 (Latin-2) character set; when viewed with ISO 8859-1 (Latin-1), the accents look a bit different.

c16.bin

Commodore 16 character set with more beautiful lowercase/uppercase character set than the C64. The lower case characters b, c, d, e, f, h, i, j, k, l and m have been improved. The font does not contain reversed characters, therefore only 2 kilobytes.

c64-german.bin

An amateur hacked version of the Commodore 64 character set, with some German special characters. This was found on a piggybacked EPROM in a German VIC-20 (VC-20). There are three inconsistencies in the reversed uppercase/graphics character set: The at sign bug/feature, the space char (the ROM tries to define a fancy cursor), and the line-drawing char C=e (code 113; an apparent bug). In the lowercase/uppercase character set there are inconsistencies in following characters: @, j, m, y, space, � (code 110; the reversed � is corrupted).

c64-hungarian.bin

An amateur hacked version of the Commodore 64 character set, with some Hungarian special characters. Except for the at sign (in the uppercase/graphics character set at position 0; in the lowercase/uppercase character set at position 100), the reverse character set is consistent.

c64-swedish.bin

Official Commodore 64 Swedish/Finnish character set with the �, � and � characters. In addition to the at sign bug/feature, there's a bug in the reversed upper case � character in both character sets.

c64.bin@ (link)

901225-01 Commodore 64/128 character set. Every vertical line is at least 2 pixels wide in order to avoid color errors on television. Also the C=M and C=G graphic characters have been made 2 pixels wide, which is an error. The reverse at sign is not an exact reverse of the character, which can be seen either as a bug (because of the 2 pixels minimum width restriction) or as a feature.

c65-caff.bin@ (link)

Commodore 65 alternative character set, taken from a C65 ROM with the checksum $CAFF. This is an exact copy of the Commodore 128 character set.

pet-1.bin@ (link)

901447-08 PET character generator ROM (BASIC 1). The character design is the same as in 901447-10, only the lower case and upper case characters have changed places. Reversed characters are absent.

pet-2.bin@ (link)

901447-10 PET character generator ROM. Used in the Fat 40, 8032SK and 8296. Doesn't contain reversed characters. This ROM is just like the VIC-20 character set, except that the code $1c (in both halves) is backslash (\) instead of the British pound sign (�), which was used in the newer character sets.

pet-swedish.bin@ (link)

901447-14 PET character generator ROM with the characters [\]{|} replaced with ������.

superpet.bin@ (link)

901640-01 SuperPET character generator ROM. The first half of this ROM is identical with pet-2.bin, and the second half of this ROM contains a true ASCII character set and an APL character set.

vic20-german.bin

A German character set modelled after the Vic-20 character set. Used in the German Commodore 128 (top part of the 315079-01 ROM) and in the German 64DX (C65) prototype.

vic20-norwegian.bin

A Norwegian/Danish character set modelled after the Vic-20 character set. Used in the Norwegian/Danish Commodore 128. The characters @, !, /, <, > and the up arrow are different, and so are many graphics characters. The characters [�] have been replaced with ���.

vic20-swedish.bin@ (link)

A Swedish/Finnish character set based on the Vic-20 character set. Grabbed from a localized VIC-20. The reversed lower case � is malformed. Chip markings: NEC JAPAN R22101-207 / D2332C 510 UD7. (Yes, it is a mask-programmable 4k*8 ROM!)

vic20.bin@ (link)

901460-03 VIC-20 character generator ROM. Most lines are 1 pixel wide, since there is no possibility of color errors with the Vic's wide pixels. This character generator is also used on many PET computers.

computers/

Firmware for Commodore 8-bit home computers. The chronological order is: VIC-20, C64, plus/4, C128, C65.

b/

The Commodore 600 series was known as the B128 in the United States, and the machine that was known there as the B256, was called the 700 series in Europe. These machines are also known as "CBM II Low Profile" and "CBM II High Profile", respectively.
The 600 and the 700 series are almost identical, but 700 series machines have a built-in monitor, a separate keyboard, and a different character generator ROM. The 610/710 has 128kB RAM, the 620/720 has 256kB RAM, and the 630/730 has 256kB RAM and a co-processor card (Z80 and 8088 were planned, but it is not sure if these cards actually existed).

drives/

Firmware for Commodore disk drives.
According to William Levak, Commodore used six different native disk formats:
2040/3040 - This is slightly different from later formats: tracks 18 - 24 have 20 sectors instead of 19.
2031/4040/1540/1541/1551/1570 - single sided, single density, 48tpi
1571 - A double sided version.
8050 - single sided, 96tpi
1001/8250 - double sided, 96tpi
1581, 3�" DD with MFM
While we're on the subject, Commodore's single density drives are actually double density, and the double density drives are actually quad density. Quad density disks have the same capacity of high density disks, but the magnetic film is compatible with double density disks.

Serial bus based Commodore disk drives

1541/

This directory contains ROMs of 1540, 1541, 1541C and 1541-II drives.
The ROM checksums are valid. If you add the byte values together (adc data:adc #0), the sum of the $c000-$dfff ROM will be $c0, and the $e000-$ffff ROM will add up to $e0. This applies also to the halves of the 1541-II ROM.

1540-c000.325302-01.bin

The ROM chip for $c000-$dfff. This seems to be the same on all models before the 1541-II.

1540-e000.325303-01.bin

The firmware of an 1540 (the drive that the C64 wouldn't keep up with). The revision number might be something else than -01. A speciality of this chip is the power-up message: 73,CBM DOS V2.6 V170,00,00. Did Commodore want to call the drive V170 first? The ROM checksum is correct. The long-board 1541 had the same hardware as the 1540; this upper ROM was the only difference. The lower ROM was 325302-01 on both drives.

1541-II.251968-03.bin

1541-II firmware. Released in 1987.

1541-c000.325302-01.bin@ (link)

The ROM chip for $c000-$dfff. This seems to be the same on all models before the 1541-II.

1541-e000.901229-01.bin

This is believed to be the first revision of the 1541 firmware. The service manual says that this ROM is for North America and Japan only. According to it, a 901229-02 also exists, but not in North America. 901229-03 is said to be the first version that is usable in Europe.

1541-e000.901229-02.bin

Second version of the 1541 firmware. Uploaded by Raymond Day <[email protected]>. Two delay loops are shorter than in 901229-03, and the checksum byte at $fee6 has been adjusted accordingly.

1541-e000.901229-03.bin

The firmware of an old-style 1541 with long board. This ROM has an autobooting feature: if CLK and DATA are held low during bootup, the drive will wait for them to raise, and execute a "&*" command.

1541-e000.901229-05.bin

The firmware of an old-style 1541 with short board.

1541C.251968-01.bin

The firmware of an old-style 1541 in white case. This drive was introduced around the same time with the C128 and the 1570, to make it look like the C128 and the 1570, which was also in a white 1541-style case. The C128 was also white. This drive has an optical track 1 sensor, but it won't be used unless the jumper J3 on the board is cut.
The $c000-$dfff part of this chip is identical to the 325302-01 ROM.

1541C.251968-02.bin

An upgrade ROM for the 1541C. There are patches in both 8k halves.

1571/

Here is the firmware of the 1570, 1571 and 1571CR drives. There are some differences between these drives. The 1570 is single-sided, while the others are double-sided. See the README file for details.

1570-rom.315090-01.bin

The firmware of a 1570 disk drive. The board may say "1571 disk", but the 1570 and 1571 were very similar anyway, the most remarkable difference being that the 1570 has single-sided drive mechanism.

1571-rom.310654-03.bin

The firmware of a 128D's built-in 1571 disk drive, or of a stand-alone 1571.

1571-rom.310654-05.bin

An upgrade of the above. Corrects the bug of 310654-03 that moves the R/W head between each sector when writing on the disk's top side.
