Greetings! I was initially planning on setting up my mid-late 70's 8080 computer on wire-wrapped S-100 boards. However, I found that S-100 prototype boards are very expensive. Bill Dudley suggested I use a standalone prototype board that he had, but it has limited real estate for things like memory and disk control circuitry. It has an expansion connector, but it is a proprietary connector. After some research, I think I may have found the solution: Intel's Multibus. For one thing, wire wrap prototyping boards have more area and are readily available (and inexpensive.) A multibus power supply puts out standard voltages which do not require regulators on each card. Is this the ideal solution that I'm thinking it is, or am I overlooking something? TIA Joe Giliberti
