BetaTech processor board installed on our base board


We wanted to replace a Welch-Allyn barcode reader for a tyre plant. A processor board was available from BetaTech in Johannesburg, which we were jointly working on for FPGA based peripherals and a Linux port. The processor board was covered in BetaTech Base Board. We had no interest in complex BGA component placement, so the idea of a simple base board was very appealing. Not sure when the board was made, but the date is 2002 on the layout. It was between October and December 2002, as that was when we worked on the second BetaTech board, and before we found out that their next board would have different pinouts. A short while later we would also find out that they had been acquired and moved overseas. There was no point in even populating the base board, and all ColdFire work was put on hold.

The base board had two RS-232 serial ports, three RS-485 ports and an Ethernet RJ-45 connector. The other connectors were for a LCD panel (Hitachi 8-bit) and the JTAG debug port. A few status LEDs were for debugging communications. There was also a JTAG port for the Xilinx FPGA.
