I'm in the process of restoring an Intel 310 system. I had it working to
the point where it was trying to boot - when the 88/45 processor
began to fail intermittently and then solidly. My debugging seems to
indicate that the problem is in a PLD - which is a serious bummer.
I have preserved the ROMS (which have built-in diagnostics/debugging
and boot capability for both floppy and Winchester hard disks) as files.
I will make these ROM files available to Al for posting on bitsavers.
If someone on this list has an Intel 88/45 (or Intel 310) who would be
willing to part with it, please contact me off list. I can to either do
a trade or cash purchase...
Cheers,
Lyle

Hi Lyle
What is a 88/45? I look up the 310 systems on the web but none mention 88/45.
Is the PAL for address decoding or something more complicated?
Dwight

Good catch, Dwight! It was a typo. I have two 88/45 boards and don't
need more. FYI, here's a link describing the 88/45:
http://bit.ly/2N6zKGe
Here's the description of the iSBC 88/30 that I NEED in the maintenance
manual for the System 310:
http://bit.ly/2MWMij5

Not sure. Likely for address decoding but I haven't tracked down
what else it might do. Another System 310 restorer had the identical
symptoms and issues with his 310. To be more specific: The system
begins startup and then halts (run light off) after about a second of
running. The hardware manuals says that error is either an iSBC error
or DMA hanging the system. I pulled all the DMA I/O cards from the
system to make sure it wasn't DMA...
Repeating the CORRECTION: I NEED AN iSBC 88/30!!!
Thanks again, Dwight!!!
Cheers,
Lyle

Maybe a iSBC 86/30?
I don't have any of these. All I have are a couple 8080 iSBC boards.
