PC Specialties has released a six-slot expander board and a memory expansion board for the VIC-20.
The VM101 expander board includes a rotary switch that can shut off the eight data lines from three of the slots, leaving auto-start game cartridges plugged in.
The board's other three slots feature an octal bus transceiver that buffers all data lines into and out of memory expansion or I/O interfaces. It also includes a reset switch to regain keyboard control when RUN/STOP-RESTORE won't.
The cost of the board is $87.
The VM201 memory expander is available in 8K, 16K, or 24K configurations. The 8K board sells for $59, and additional memory can be added for $28 per 8K block.
