STB1 Overdrive

General Information

This board is really designed to be plugged into a 5512 board, and act as a coprocessor. However, it is can be run standalone no problem and has the advantage of being quite small.

The board offers 3 PCI slots, all at 3.3V. The board has 32Megs on the LMI, there is no flash on board but a flash STEM module can be used if you require some. The board also has a Hitachi HD64465 perhiperal chip, which provides some useful peripherals, not all of which are supported. We have had no problems with this board.

Known problems with this board

• No FRAME signal on STEM

  This is only relevant if you are attempting to interface an MPX device through the STEM connector.

• No -12V supply

  The lack of a -12V supply is not usually a problem, except for sound cards which require -12V for the analogue output stage.
