| July 21, 2008, 06:13:07 AM Take a look at this link: http://www.stud.uni-hannover.de/~mheine/AEcastro.html Amiga computers used at NASA for telemetry. A clue perhaps? |

| July 21, 2008, 06:02:40 AM Here's my best guess: The cards are part of some kind of telemetry system. I looked up the stats on the two large chips. They are Dual Ported Ram chips. Hence the name DPM on the card. The other card is labeled PCM, so I'm guessing that these things get connected together to make a system of some kind. Pulse Code Modulation is used in telemetry. Like I said, my best guess.  Info on the chips: http://www.idt.com/?genID=7026 |

| June 25, 2008, 06:36:49 PM In this view bottom right of the PCB is printed "AMIGA 4000 DPM IN...". It seems to be a DSP card or something. The 2 big chips may me DSP's. The 71256 DIP could be (S)RAM. I've also never seen such a card before. |
