I also have an H8 with no disk controller. The board I'd like to find
for it is the H37/H47 controller. I'm even willing to build one myself
if I can find enough documentation.

I have built H37 controllers for the H89. In fact, I'm trying to do so
now. I have PC boards, almost all the parts, and have one almost
finished. If I can only find a source of Western Digital WD2143M-03 and
WD1691PE chips I should be in business.

The H8 board, being larger, may not have used these rare chips. There
are alternate circuits, but they take more PC board space. Does anyone
have a schematic and layout for the H8 H37 board?
