"Original Ultimate Interface"
This is a universally applicable dual 6522 Versatile Interface Adapter board
with four 8-bit fully bidirectional I/O ports, eight handshake lines, and four
16-bit timer/counters. It has IRQ interrupt capability and is expandable
to four boards. It works on the C64 and all modes of the C128 (including
CP/M mode). Its model number is the 641F22.
A/D Conversion Module
This unit is 16 channel, 8-bit, 100 microsecond conversion time.
Piggy-backs on the 641F22 and thus requires it to operate. Works on the
C64 and all modes of the C128 (including CP/M mode). Its model number is
641F/ADC0816.
