VMAX-301 Compact 486 Single Board Computer at Lely Tempustech, LLC.

The VMAX® 301 is a half sized, low cost CPU card. Its Plus 5V only operation
and low power usage make it ideal for power critical applications. With the
capability of up to 16M of DRAM, the VMAX® 301 can be expanded to handle
even the largest of tasks. The model 301 includes all of the popular peripheral
functions found on higher priced cards.

Using standard 9-bit SIMMs allows the VMAX® 301 to hold up to
16M of high speed DRAM main memory. The compact size (XT height),
makes the 301 a solid platform for expansive design capabilities.
