You are bidding on a used working Keithley Metrabus PDMA-16 Parallel Digital Interface Board. It ia an ISA Bus Card, s/n 038378. 

The PDMA-15 high-speed, labit, paralleldigital interface card with DMA (Direct Memory Access) plugs directly into an expansion slot of the IBM PC/XT/AT and compatible machines, including the AT&T 63300. All digital 1/0 feeds through a 37-pin, D-type, male connector that projects through the rear mounting plate.

Typical applications for the PDMA-16 are as follows:

  • Interface for high-speed digital peripherals.
  • Arbitrary waveform generation with an external D/A converter.
  • High-speed A/D conversion with an external A/D converter.
  • High-speed digital stimulus for testing and control.
  • Fast block transfer of data between computers.
  • Interrupt or DMA driven background data transfers.
  • High sink current lTL digital 1/0 (24mA sink current).
  • Data line monitoring.
  • Transient generation and monitoring.

Good Luck in Bidding!
