I have found various specifications for using the S100 bus for a single-board computer running the Intel 8080 or Zilog Z80 processors (think Altair/Imsai), but I would like to know if there is a specification for the extra signals on the Intel 8085 processor, namely Restart 5.5, Restart 6.5, Restart 7.5 and TRAP.
There are vectored interrupt lines in the S100 spec, but I've only seen them used to interface to an 8214 Priority Interrupt Control IC.
Should I stop being picky and just use four vacant lines, or is there an established standard for this?
Also, any great sources for a few S100 backplanes? I don't need a 20 slot, but a 4 slot would probably not be enough--so somewhere in the middle would be good. I intend to have Protocase build me the cases for this project.
Input is appreciated, thanks!
