C64 ULTRACART 128 Cartridge Revision 3 (128 ROM titles installed) c64_ultracart128

ULTRACART 128
The UltraCart 128 is a cartridge for the Commodore 64 that is capable of holding 128 cartridge images in dual 1MB EPROM's, supporting both 8K and 16K cartridge ROM images, with Ultimax image support.

The UltraCart 128 uses two matrix segment displays to show the bank number and the image number. Two toggle switches in binary select the bank number, and the third toggle switch selects which EPROM is in use. The two ultraminiature toggles are LED illuminated, and will illuminate when active to indicate the binary value for the bank in addition to the matrix display, and the ROM select toggle will always be illuminated, green for EPROM #1 and red for EPROM #2. Likewise, a fourth ultraminiature toggle will glow amber when Ultimax mode is enabled. The UltraCart 128 uses a hex encoder switch to select the ROM image.
