Diego Checkmate
CRG-Glen·DIEGO-500·KICAD/Checkmate/Diego Checkmate.kicad_pcb
Diego Checkmate is an open source PCB design by CRG-Glen: a 4-layer, 275 × 95 mm board with 126 components (48 distinct parts). It is built around the C90569, 74ALS245, 74LS245, 74LS32 and more.
Turn your A500 into an A2000
Turn your A500 into an A2000 with this sidecar backplane CHECKMATE VERSION NOT YET TESTED - DO NOT BUILD
DIEGO is a Zorro 2 backplane expansion for use on your A500 either as a side car project or within your Checkmate case. Diego gives you an A2000 compatible CO-PROCESSOR slot (side car version only) along with a full set of 5 ZORRO2 slots all made possible by the onboard Bluster IC. Bluster is a remake of the classic A2000 Buster chip by LIV2 although it is a custom version for DIEGO to handle inverted clocks and provide some further functions.
