64c.251913-01.bin 1998-03-29 16384
Commodore 64c BASIC and KERNAL, a 23128 ROM chip composed from the 901226-01 BASIC and 901227-03 KERNAL ROMs.
64gs.390852-01.bin 1998-05-12 16384
Commodore 64GS BASIC and KERNAL, a 27128 EPROM chip from 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 is otherwise normal, but it uses fill byte $00 instead of $AA. The KERNAL 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 changed to $FB4D, which in turn jumps to $F707, which in turn causes I/O error #5.

Commodore 64 parts and firmware versions
basic.901226-01.bin 1994-01-24 8192
Commodore 64 BASIC V2. The first and only revision.
basic.901230-01.bin 2002-01-17 8192
CBM BASIC V2, taken from the BASIC cartridge for the Commodore MAX. 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. Pictures of the cartridge can be found at http://home.austarnet.com.au/avcaz/max/max.htm. There should also be "MINI BASIC I".
basic.c65.bin 1995-03-02 8192
Commodore 64 BASIC V2, taken from the Commodore 65 ROM. Uses fill byte $FF instead of $AA.
characters.901225-01.bin 1994-01-24 4096
The character generator ROM.
kernal.4064.901246-01.bin 1994-06-02 8192
Commodore PET64 or 4064 KERNAL. With black&white startup colors, and with a different bootup message. Machines with color monitors used the standard Commodore 64 KERNAL ROM.
kernal.4064.readme 1998-05-05 647
More specific information about the PET64 a.k.a. 4064 a.k.a. Educator 64 KERNAL ROM.
kernal.901227-01.bin 1994-06-11 8192
Commodore 64 KERNAL ROM Revision 1. The RS-232 timing table is designed for exactly 1 MHz system clock frequency, although no C64 runs at that clock rate. Ripped from a very old American C64.
kernal.901227-02.bin 1994-01-24 8192
Commodore 64 KERNAL ROM Revision 2. Can be found on 1982 and 1983 models.
kernal.901227-03.bin 1994-01-24 8192
Commodore 64 KERNAL ROM Revision 3. The last revision, also used in the C128's C64 mode.
kernal.901231-01.bin 2002-01-17 8192
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.
kernal.c65-caff.bin 1995-03-02 8192
Commodore 64 KERNAL ROM, taken from a Commodore 65 ROM. Dated 1990.
kernal.c65-e96a.bin 1995-03-02 8192
Commodore 64 KERNAL ROM, taken from a Commodore 65 ROM. Dated 1991.
kernal.swedish-02.bin 2001-08-27 8192
Commodore 64 KERNAL ROM Revision 2, patched for Swedish/Finnish keyboard layout. The difference between 901227-02 and this image is exactly the same as the difference between 901227-03 and kernal.swedish-03.bin: the keyboard table.
kernal.swedish-03.bin 1994-01-24 8192
Commodore 64 KERNAL ROM Revision 3, patched for Swedish/Finnish keyboard layout. The difference between 901227-03 and this image is exactly the same as the difference between 901227-02 and kernal.swedish-02.bin: the keyboard table.
kernal.sx.251104-04.bin 1994-06-02 8192
Commodore SX64/DX64 KERNAL. With different startup colors, and tape routines disabled.
kernal.sx.swedish.bin 1997-11-24 8192
Commodore SX64/DX64 KERNAL, patched for Swedish/Finnish keyboard layout.
pla-906114-1.c 2003-06-08 3265
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 2003-04-16 2182
A MACHXL design description of a replacement for the 906114-1 PLA.
pla.c 2003-06-08 7158
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 1996-11-10 12142
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 2003-06-08 96798
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.
