My initial reading (more or less my last) of the spec for the new Imsai is
that the power supply is a regulated switcher that provides the "standard"
voltages (though they're no longer standard) of +/- 5 and +/- 12 volts.
Normal S-100 hardware had on-board regulation, hence expected to see +8 and
+/- 16 on the bus.
That alone would do it, I think. The fact that it's IEEE696-standard will
ensure that some of your boards won't work, simply because the standard allows
some bus pins to be used for either signal, ground, or a supply. If it uses
it as -7 and you think you've got a clock there ... well ...

Bob Shannon -
Could you expand on your comments about non-s-100? According to the
website, it has a 10 slot S-100 MB, and "The IMSAI SERIES TWO utilizes
the powerhouse Zilog Z8S180 microprocessor and provides a complete
system on an IEEE-696 compatible S-100 board"
I am somewhat interested in the machine, but not if there is NO chance
of using some of my other S-100 boards in it.
