Circuit Board Pictures

AV3000 audio/video ZorroIII card for Amiga. This board was to be used for video capture in the sports science department. It has a Philips VMC (video memory controller), 1Meg VRAM, video overlay/Amiga video pass through, video FIFO, audio codec, 128k flashrom, expansion bus. In this photo (far top right of board) is a macrovision video bypass board.

AD0200 analogue/digital ZorroII card for Amiga. This board was used (and still is) in an ocean radar system. The board has a Motorola MC68340 embedded microprocessor, 512k SRAM (25ns), 12-bit (2Msps) A/D + FIFO, multiplexer, ZorroII bus FIFO, serial port, parallel port and expansion bus. An Amiga2000 was used to control the radar and sample raw data read back via this card.

AD0201 analogue/digital ZorroIII card for Amiga. This board is an updated version of the AD0200 with a ZorroIII bus interface, FlashROM (instead of EPROM) and more surface mount parts.

IO0100 input/output ZorroII card for Amiga. This board was used in early radar systems to control the antenna arrays. In featured dual 8255 CIA chips with both internal and external (DB37) connectors.

AD0240 video capture module for AD0201 board. This was used for testing video capture in an Amiga system. In used a Brooktree BT812 chip, FIFO and dual composite video inputs.

Back in 1994, I had remembered reading a newsgroup message quoting Dave Haynie:- "NEVER EVER mess with a PCB jumper you don't understand, even if it's labelled 'Sex and Free Beer'". So, I decided to implement this on the AD0200 ZorroII board (see above)... :)
