 Weren't you the OP? I done said Radio Electronics had a series on building
a 68K box w/ISA slots. I perused the 1st installment this morning, and yep
it'll run an MDA card (CGA probably too), and stock floppy controllers, as
well as hard disk controllers. What more could you want! Keep in mind though
the original developer is on these lists somewhere, and wants big bucks for
the (more or less complete) kit. So you'll have to contact him if you want
to use his firmware. I don't have the entire set of installments, but
presumably (though don't quote me) the artwork was available right in the

Hi Chris,

Would you please tell me which Radio Electronics like year, month, had the
68K circuit.  If the design is proprietary then it is probably not a usable
design.  What you are describing sounds like a 68K motherboard in the PC or
AT format.  My plan is to place the 68K SBC on an ISA board starting with an
ISA prototyping board.  If you or someone else would please scan the article
it sounds very interesting whether it would be useful for my project or not.

I've found a good circuit with a complete schematic and description.  It has
some firmware and appears complete.  Also it is public domain hardware and
free (speech -- GPL) software so it is an ideal home brew project.  It makes
sense to me to do a little research and select an established home brew 68K
project and use it as a base to extend to the ISA board rather than reinvent
the circuit entirely.

Thanks and have a nice day!
