Reproduction Corsham Motherboard
For comparison this is an actual Corsham Motherboard. This is a REV 3 board so there are some differences between this and the REV5 reproduction
Bare board of Reproduction Corsham Motherboard
This is a reproduction of the Corsham SS50 motherboard. It was produced from original Corsham design files. One upgrade was made to it however. A ground pour/plane was added and if you look closely at the bare board you can see the empty areas that are filled in with "ground". This is a simple addition in the eagle PCB CAD software that was made to reduce electrical noise in the motherboard. If not for the addition of a ground pour, this board would be identical to the Corsham REV 5 motherboard.
This is Corsham's SS-50/SS-30 motherboard. It was designed to complement their 6800 and 6809 CPU boards and SS-30 peripheral boards. It is smaller than vintage motherboards, but that’s because fewer slots are needed for a complete system. If you feel you may made need more slots in the future, please look at the SWTPC reproduction motherboards.
