This gent scratch built a Z-80 based CP/M machine and then attached an
INMOS transputer chip to it:

Grr, I am so jealous! I have half a dozen transputers of various models,
stacks of technical manuals and even a C004 crossbar chip, but no C011
or C012 to interface to any of them through...
Does anyone have contact info for this gilesgoat fellow?
Does anyone have an Inmos C011 or C012 they'd be willing to part with?

In theory you can manage without one. The first Inmos transputer boards
-- the ones used in the ITEM -- didn't make use of the link adapter chip
chip (I was told the transputer was available before the link adapter
chip).
What they did was to map a serial chip (normal asynchronous thing) into
the transputer's address space. Buffer that to RS232 levels to talk to
the host system. And configure the transputer to boot from external ROM
(not the built-in bootstrap-from-a-link). There were EPROMs on the board
containing enough code toboot the transputer from the serial port. And
of course you you sue the 4 links of that transputer to connect to others.
Writing the necessary transputer bootstrap program is left as an exercise
:-)

Judging by the description of the link interface and the memory interface
in the reference literature I have, I think it would be easier to hack up
a transputer link than a memory-mapped device (mostly because of much
lower wire count). Some people on the internet claim to have done this in
an FPGA, and there is source for one here:

I would rather avoid that route, but it looks like it might be my only
option.

The gentleman that wrote the article that started this thread pointed me
at his source; it turns out that C011s are for sale on ebay.co.uk:

A12%7C39%3A1%7C240%3A1318
there's 3 more left from that seller, if anyone wants one. Now I need to
design a board based on this chip... can anyone recommend any books or
other sources that teach ISA and/or PCI device design? I know how to
solder and use a scope (and I could probably hack up a linux driver for
whatever I make), but I've never designed or built a circuit with more
than 3 transistors :-/
