characters/
c128.bin
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, ä (code 110; the reversed ä 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 å, ä and ö characters. In addition to the at sign bug/feature, there's a bug in the reversed upper case Ä character in both character sets. This image might be corrupt. See c64-swedish3.bin.
c64-swedish2.bin
Alternative version of the Commodore 64 Swedish/Finnish character set. Compared to c64-swedish.bin, the Ä and Ö dots and the Å ring are wider. This image might be corrupt. See c64-swedish4.bin.
c64-swedish3.bin
Character rom from Swedish c64, equivalent to c64-swedish.bin
c64-swedish4.bin
Character rom from Swedish c64, equivalent to c64-swedish2.bin
c64.bin
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
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.

keyboard-swedish.txt
Swedish/Finnish keyboard layout of the VIC-20, Commodore 64 and Commodore 128. Composed by Pasi Ojala and Marko Mäkelä.
listfont.c
C source code for displaying a 8*8 font.
pet-1.bin
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
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-greek.bin
Greek character generator ROM. Some Latin characters have been replaced with Greek ones. This font is not very consistent: for instance, the two copies of the @ sign at code positions $00 and $80, as do the two copies of the capital Phi at $06 and $c6. This character generator was found on a 4-kilobyte chip, whose first half was identical with the 901447-10 character generator.
pet-norwegian.bin
Norwegian character generator ROM.
pet-russian.bin
901447-10 PET character generator ROM modified to have Cyrillic letters in the positions $42..$5a. Contributed (manually reproduced) by Dima Sobolev.

superpet.bin
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-japanese.bin
A Japanese character set used in the VIC-1001. The British pound (£) has been replaced with a Japanese yen (¥) symbol, and the lowercase/uppercase set has been replaced with an uppercase/Kanji set of glyphs.
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 ÆØÅ.
vic20-swedish.bin
A Swedish/Finnish character set based on the Vic-20 character set. Grabbed from a localized VIC-20. The reversed lower case ö is malformed. Chip markings: NEC JAPAN R22101-207 / D2332C 510 UD7. (Yes, it is a mask-programmable 4k*8 ROM!)
vic20.bin
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).
The 500 series uses a 6567/6569 VIC-II video chip instead of the 6845 CRTC. It also runs at around 1 MHz instead of the 2 MHz of other Model B computers.

64c.251913-01.bin
The 251913-01, used in newer versions of the Commodore 64 and some versions of the Commodore 128, is a 16-kilobyte 23128 ROM chip. It contains the Commodore 64 BASIC interpreter ($A000-$BFFF, corresponding to the 8-kilobyte 2364 ROM chip 901226-01) and the Commodore 64 KERNAL ($E000-$FFFF, corresponding to the 8-kilobyte 2364 ROM chip 901227-03) in that order.
64gs.390852-01.bin
The 390852-01, used in the ill-fated Commodore 64GS game console based on the BN/E circuit board, is a 16-kilobyte chip similar to the 251913-01. This one was archived from a 27128 EPROM 27128 EPROM chip in a West German machine DA5 016014E, assy no. 250469, 252311 rev.B. The chip has the label © 1984, 90 CBM / 390852-01 / C64GS ROM CS=DF34. The BASIC part corresponds otherwise to 901226-01, but the 30 unused bytes at $BF53-$BF70 are filled with $00 instead of $AA. The KERNAL part has been modified from the 901227-03, and most modifications are in the area $F72C-$FC92, which also contains a copyright message. Many jumps have been redirected to $FB4D, which in turn jumps to $F707, which in turn triggers I/O error #5.

kernal.325017.swedish-02.bin
Commodore 64 kernal from unit with Swedish keyboard layout.
kernal.4064.901246-01.bin
This 8-kilobyte ROM has been reported in various machines (4064, PET64, EDUCATOR64), which are versions of the Commodore 64 built in a PET case with an integrated monochrome monitor. The system interrupt routine resets sprite, background and border colors to black unless the high-order bit of the location 646 (cursor colour, $0286) is set. Using any colour command resets location 646 and, therefore, the colors.
kernal.901227-01.bin
This 8-kilobyte 2364 ROM is the first revision of the Commodore 64 KERNAL. The RS-232 timing table is designed for exactly 1 MHz system clock frequency, although no C64 runs at that clock rate. Unlike later KERNAL revisions, this one does not detect the video system (PAL/NTSC). This KERNAL was probably only used in early North American Commodore 64 units.
kernal.901227-02.bin
This 8-kilobyte 2364 ROM is the second revision of the Commodore 64 KERNAL. It is the second most widely spread version.
kernal.901227-03-DK.bin
Commodore 64 kernal from unit with Danish keyboard layout.
kernal.901227-03.bin
This 8-kilobyte 2364 ROM is the third and essentially last revision of the Commodore 64 KERNAL. It is the most widely spread version.
kernal.906145-02.bin
This 8-kilobyte 2364 ROM is from a Japanese release Commodore 64.

pla-906114-1.c
Another version of pla.c, corresponding to the logic equations obtained by Jens Schönfeld. The equation for CASRAM is much simpler.
pla-906114-1.pds
A MACHXL design description of a replacement for the 906114-1 PLA.
pla.901664-01.bin
pla.c
This C program contains the logic equations for the 82S100 PLA chip used in the C64 (906114-1), and converts them to a 64-kilobyte truth table file. In this second version of the program, the input and output lines are permuted so that they correspond to the 82S100-to-27512 adapter built by Jens Schönfeld, so that he could read out the PLA with an EPROM programming device.
pla.txt
Logic equations in Abel format for the 82S100 PLA chip used in the C64 (906114-1), and a JEDEC file that can used to burn a 82S100 as a 906114-1.
pla.zip
An MS-DOS program for displaying the memory map of the Commodore 64 in different configurations. Turbo Pascal source code included. The archive also contains a picture of Jens Schönfeld's SuperPLA adapter board.

basic.901230-01.bin
CBM BASIC V2, taken from the BASIC cartridge for the Commodore MAX, also known as VIC-10 or UltiMax. Unlike the BASIC interpreter in the Commodore 64, which resides at $A000-$BFFF, this one is located at $8000-$9FFF. The 2764 EPROM was hand labeled 901230-01. The board in the cartridge has three chips: two 2764 EPROMs (U1, BASIC and U2, KERNAL) and one HM6116P-4 SRAM (U3). The bottom side is marked FAB 326314, A/W 326315 REV A, and the top side is labelled EPROM/EPROM/RAM and ASSY 326312. See also kernal.901231-01.bin. There should also be "MINI BASIC I".
kernal.901231-01.bin
Commodore MAX KERNAL ROM, taken from the BASIC cartridge for the Commodore MAX. There is a copy of the standard Commodore 64 upper case character set (corresponding to the first half of 901225-01) located at $F000-$F7FF. The 2764 EPROM was hand labeled 901231-01. See also basic.901230-01.bin.

c65/
The Commodore 65 was never produced. These ROM images are from prototype units. The number codes are date codes: YYMMDD.
910111-390488-01.bin
This is the ROM from the C65 (Alan Share's), checksum $caff. The date on boot up is 910111. The ROM date (at the beginning) is 910110. A bit modified character set at $9000, with taller b and d letters, for instance. Normal characters at $D000.
910429.bin
This is the ROM from the C64DX (Russell Alphey's), checksum $e96a. The date on boot up is 910429. The ROM date (at the beginning) is 910501. German character set at $9000. Normal characters at $D000.

911001patched.bin
This is the ROM from a C65 (Thomas Hechelhammer's), dated 911001. The ROM date (at the beginning) is 911008. Based on 911001.bin, this version has been patched by
bobek@boxpl.com to replace the BASIC program which does disk
accesses with a different program that drops the user into
the built-in monitor.

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, 3½" 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-II.355640-01.bin

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 <raymondday@hotmail.com>. 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

A comparison of the 1541C and 1541-II firmware by Wolfgang Moser. The support for the optical "track 0" sensor, which was introduced in the 1541C firmware, was removed in the 1541-II firmware.
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.

This is the contents of the 6530 RIOT chip for the floppy controller (unknown revision, looks like a slightly patched 901869-01)
Ville Muikkula reports that his 8250LP has a little circuit board inserted in the place of the floppy drive controller 6530 RIOT chip. Located on this circuit board are the original 901869-01 and a 2732 EPROM chip that has a label with part number 251474-01B, and agrees with this dump. The extraneous 3 kilobytes of the 2732 are filled with $aa.

9090/
The Commodore D9060 and D9090 can use the same firmware. The difference between these units is that the jumper J14 on the DOS board is open in the D9060, and closed in the D9090 to select a 4-head vs. 6-head drive. The jumper J13 seems to be unused.
According to Wolfgang Günther, the EPROM type may be 2564 or 2764, depending on the board version ("Assy No. 300012-001, Rev.B" or "Assy No. 300012-002, Rev.A"). This is the case of 300516/300517 rev.C.
