[LOOKING FOR] HOLMES Engineering, DX-3D Manual

[Patrick.B (TTR)]

I am looking for the HOLMES Engineering, DX-3D schematics and or Manual
This is a TRS-80 floppy drive controller board
Does anyone have a copy of it?

here is what the board looks like

bump 2 years later.. still looking for this

I'm just judging here by the absolutely comical routing on that board that this was a low-run product? Mail-order?

@Patrick.B (TTR): what's that main DIP40 IC?

@NeXT: why comical?

I can't read the number but I would expect a floppy controller chip on a floppy controller card. Maybe from Fujitsu? (8876)

 

[Patrick.B (TTR)]

Yes it is a floppy disk controller, that I already know. Just looking for the manual m thanks for the input

Well there's a lot of well thought-out arrangement of traces, followed by spots where you can clearly tell they messed up and drew it in by hand.
Stuff like the lower right where you have one nice trace that links to a via, then two traces that loop around it.

Ah ... I did notice that one -- actually it's hard to miss! Had considered it to be "relaxed routing rule applied here" :->.
