Thanks Terry, But the 571000AD's program and check out on the programmer
A-O-K. I have a dataman S4 that supports the chip directly (128kx8) but
they just don't seem to work on the 332 board. I copied the EPROM that has
the motorola CPU32Bug that was sent and it will not work. The speed is
within range, so either the eproms are really out of spec, or they are just
different. I really have no idea if the 571000's are the same. I got them
at fry's, and they are about one step above the shack (as far as I am
concerned) they were marked in the plastic pack as 27c010's but that may be
BS!
