Then they all seemed to vanish as the PC's and the Mac's took over the Personal Computer market place. I grew up using real hardware -- PDP/8e,PDP8/S, IBM 1130. Even snuck in some time on a VAX. I don't mind people writing emulators but I feel hardware just has a better HANDS on feel for what machine can do. I have to some day get a REAL terminal (Hardware) so I can get my PDP 8 clone runing with the right feel. TTL and BIT Slice design I can handle but software for a small machine is out of my ball park. I expect to spend about 2 grand on a one of a kind homebrew but then I will have learned a little about hardware from the mid 1980's. I am playing around now with a 20 bit machine, since all I have is 21 flat handle toggle switches for a hardware front panel. I ordered 24 but they goofed and sent 3 momentary switches instead. I could design a 16 bit machine, but then I am back to the classic architecture with a single AC: {OP}{INDIRECT}{ADDRESS}. All most all the modern Instruction Sets are from the late 1970's and they are very complex -- 68000,8088/8086 ect. I am looking for design in the middle, and even that is hard since BIPOLAR PROM is very hard to find nowdays.I am using a CPLD since I have one rather than 4 - 512x8 PROM's.
