I went looking and found an old storage device (binder) with long-term storage technology elements (sheets of paper) for my old R65F11 designs. Not the entire thing, but a couple hundred pages of H-CAD (hand drawn pencil schematics), printed code listings and manuals. Here's the main processor board:

Here are the front pages of three data sheets I have:

In the documentation set I have a full printed listing for some version of the code editor I wrote as well as a pile of utilities and drivers. This is dating back almost exactly 40 years.

Also have the schematics for various interface boards, including a floppy disk interface board and, I believe, the driver I wrote to run screen-based code storage and retrieval from it. This was a very long time ago. I can't remember how closely these schematics and code matched working hardware.

If any of this could help you I might be able to scan and post somewhere. It will take some work because I have to use a flat-bed scanner. It's amazing how well paper and vellum survive four decades inside a binder.

Thanks for the uploads! I will check today but I believe I've got hardcopy of the datasheets/appnotes you have -- Burgess also grouped design docs into binders, so I have his originals. It's a habit I started carrying over to my own projects a number of years ago, never have to worry about something being deleted by accident, a format becoming hard to read (switched EAGLE CAD -> KiCAD 9 years ago), etc. Plus, I find it easier to read dead tree reference material when working with something on the bench!

We did a R6501Q based SBC a number of years ago, and eventually got RSC FORTH kernel and development ROMs running on it. We'd found a copy of the ROM object code in Burgess's archives and got it going from that. I want to eventually add a floppy controller to it, a friend had been working on replacing some of the floppy-based screen storage with CompactFlash backed storage, but got busy on other things.

What was the intended purpose for your R65F11 hacking?

Confirmed, I have all of the datasheets/appnotes you posted first page pictures of!
