Hmm, weird. I tried to read the ROM contents from the 8355 in my
SDK-85, but my Data I/O UniSite, when configured for an 8755A,
complains of a device insertion error. Everything is set up
properly, and the UniSite is fine, I use it all the time. I've
checked the databooks and the 8355 and the 8755 should be completely
interchangeable with the obvious exception of programmability.
I've not fired up this SDK-85 for a few years, but it worked fine
then. I have to go to sleep soon, and I'll be out for much of the
day tomorrow, but perhaps tomorrow night I'll be able to wire it up
to a power supply and see if it still runs.
