Right here I contemporary recordsdata on the BusCard, an IEEE-488 and parallel printer interface for the Commodore 64. The BusCard, and subsequent BusCard II, had been manufactured by Batteries Incorporated Ltd. of Toronto, Canada. On my BusCard, the circuit board is labeled “Rev A” and “1983”. I ragged it to present IEEE-488 functionality to my Commodore 64 in bid to make exercise of a 4040 disk pressure and 8023P printer. It also provides BASIC 4.0 and comes with an assembler and disassembler.
Unlike the BusCard II, the BusCard would now not possess any proprietary integrated circuits. Which capacity, I change into in a job to efficiently reverse-engineer it and produce an true working replica. I ragged EAGLE CAD plan for the schematic and circuit board compose. All recordsdata required to present it’s equipped beneath. Once that you just can well presumably make a choice to assemble it, that you just can well presumably ship the GERBER files equipped beneath to the manufacturer of your quite quite loads of. That possibilities are you’ll highest need EAGLE within the occasion you make a choice to trade the board layout or circuit.
