Firmware for all variations on the Commodore 64k computer. The eprom type for 8k BASIC & KERNAL is a 2564. A 2764 can be used with an appropriate adapter. Char roms can be replaced with a 2532, or a 2732 with adapter. The 16k rom in the 64C can be replaced with a 27128 eprom.

64c.251913-01.bin 2018-03-07 16384 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 2018-03-07 16384 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. 82S100+Jedec.zip 2018-03-07 10486 PLA binary generator and source basic.901226-01.bin 2018-03-07 8192 Commodore 64 BASIC V2. The first and essentially only revision, located at $A000-$BFFF. In the 64GS system firmware, the 30 unused bytes at $BF53-$BF70 are filled with $00 instead of $AA. In the Commodore 65 firmware, these bytes are filled with $FF.

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 2018-03-07 8192 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 2018-03-07 8192 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 2018-03-07 8192 Commodore 64 kernal from unit with Danish keyboard layout. kernal.901227-03.bin 2018-03-07 8192 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 2018-03-07 8192 This 8-kilobyte 2364 ROM is from a Japanese release Commodore 64. kernal.c64-scand.bin 2018-03-07 8192 Kernal on a 2764 from a Scandinavian SX64.

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 2018-03-07 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 2018-03-07 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.
