Well yes, I assembled it from parts....considering how much I dislike PCs I
was hardly going to design my own motherboard. LOL!
>....Who made the mobo if that was the case....
No idea, it was far too many years ago. All I can say with certainty is that
it was of Japanese manufacture.
When I came to build that machine I had a fairly tough time tracking down a
decent XT motherboard, by then even the '286 was old hat with most vendors
pushing '386 based mobos. In fact, IIRC, this was the only V30 motherboard I
could find over here at the time (though that doesn't meant that others

There were certainly a few pre-built PC clones around which used the
8086/V30, the Amstrad 1512/1640 spring to mind.
As I said, when I came into PCs no-one wanted XT motherboards anymore (apart
from me, as the '286 was a dog and the '386 was still too pricey for a
second computer I'd rarely use) so I don't really know what had been

Hmmm, you know, it may have been an "Orchid".... I definitely remember
having an Orchid manual in amongst some AST manuals I kept in a little ring

I never had any of those, but I did have one or two "multi I/O" cards for
the XT, which assuming the processor upgrade was by "Orchid", would be what
the "AST" manuals were for.
Printer/serial, clock/calendar, that sort of thing.
I got rid of all that stuff sometime in '92 when I upgraded to a '386DX
