I vagely recall hearing about unpopulated Apple II clone boards that could be bought individually back when they were new, along with the well known S-100 boards.

Was such an option available to PC builders?

I believe so, I recall seeing images of one once.

Otherwise, there's always this!

Also, a Google search yielded this result:

On page three (linked) are two images of an unsoldered board.

I recall seeing an unpopulated ERSO style XT clone motherboard sell on eBay a while back.

Maybe this? (http://www.vintage-computer.com/vcforum/showthread.php?46729-MBC-XT-clone-mainboard-circuit-board)

Also, there was the "Big Blue Seed" as well as an almost-PC board in one of the magazines. IIRC, it used a RS232C serial connection for display and keyboard.

you can buy a PC clone kit for about 200 US$ here:

Good to know, thanks.

Interesting. I'm guessing it was more-or-less like using a real PC with CTTY?

There's a good chance I'll get one of these, or perhaps a Sergey's XT if they're still available.

Hello, I don't remember how it got into my collection about twenty years ago...

As most components have prints with IC type and resistor/capacitor values, it should be possible to make a working XT clone board with it. Manufacturer is unknown, just "Made in Taiwan".

After looking through "The Big Blue Seed", it looks like the "Super XT Motherboard"
