OSI 560Z card (PDP-8 emulation on OSI) info / software

Hello, I'm looking for any information on the OSI 560Z card.? This was an OSI plug-in card that had an intersil/Harris IM6100 chip, and a Z-80 chip both under control of the 6502 Host CPU.? The card also had 64K of RAM on board, which could be accessed by the 6502 via a sliding 4k window at a fixed address in the 6502 memory map.? This allowed emulation of a PDP-8 via the 6502.? I found the schematics on Mark's OSI page (http://osi.marks-lab.com/boards/boards.html), but I'd love to find the manual and software.? If anybody has a manual or software, and care to share it (and let me post it on my web site, http://osiweb.org), I'd be grateful. I just did a quick search, and found a similar query from 2004, but I think enough time has passed that some new lead may turn up. Happy classic computing! Dave
