Board Offers 24K Additional Memory For VIC 20

Quantum Data Inc. of Costa Mesa, CA announced the first of its new products to expand the capabilities of the Commodore VIC 20 personal computer: A Board allowing up to 24K of additional user memory. Designated the QDI Expandor, it expands the memory of the VIC to a total of 29K bytes.

Designed for those users who need more than the 3K of user RAM available on the VIC, the QDI Expandor is available in several configurations from 0K to 24K of additional memory. The board uses state of the art memories which allow the board to consume less than 150 MA even when fully loaded with RAM. These memories are also pin compatable with popular EPROMs and ROMs and they can be mixed and matched in 8K blocks.

In its standard configuration, the QDI Expandor uses memory from HEX 2000 to 7FFF but it may also be jumpered to operate one of the 8K blocks in the A000 to BFFF range, "Where the ability of the board to handle ROMs is very convenient," explains Dick Edwards, QDI's president.

"That's because the VIC starts looking at location A000 on power up to see if there is a machine language program present in ROM, and, if there is, it will run that program. We expect this feature to be of special interest to systems houses, who are going to use this computer where a resident machine language program is important."

Measuring 4.5 by 6 inches, the QDI Expandor can plug directly into the VIC memory expansion port or in the expansion chassis that QDI will soon be announcing. Priced at a suggested retail of $295.00, the board is available from stock.
