Sorry no but I’m in communication with the guy who bought it and he’s saying there’s a downloadable dump of the floppies online somewhere. I’ll circle back and ask him to share the location. He also said he was planning on building a schematic of the cards so that others could build their own...

Back in the day it definitely made economic sense to go the more “urban sprawl” route but, yah, now today not much. Maybe the draw is the unique ascetics.

How rare/desired is the Titan Industries QX-PC Co-Processor made for the QX-10? Did most owners end up getting the upgrade so they could run MS-DOS and DOS software or was it more rare. I have both the coprocessor and the associated DRAM card and am trying to get more information about it.

I don’t have the keyboard but I do have the add-on QX-PC co-processor kit made by Titan Technologies. It adds a 16 bit co-processor and 192k DRAM to your QX letting you run most DOS software. Pls Let me know if you want more info on that and if you be interested in it.

Turns out I didn’t even know I had the DRAM card for this as well. It came as a kit and I have both the 16-bit 8088 based co-processor card and the 192k DRAM card that mounts parallel in the QX-10. Both are up for grabs on one listing

Found out the buyer takes hard to find but in demand cards like these and fabricates working clones. He promised at my request to keep me in the loop on his progress with this one.

Up for sale is a Titan Technologies QX PC board for the Epson QX 10 / QX 16 line of computers. This board allows the QX computers to run MS-DOS and compatible software. I am selling this board as non-tested / non-functional because I could not test it. Free shipping for US 48. I can ship it...

Interesting! He must be in this book I’m reading. https://cdn.preterhuman.net/texts/computing/apple/AppleDesign.pdf See page 267 on the “InstaTower”. Are you in this book?

Agreed. The more I try to find info on this PSU the more I’m seeing it’s a one off. Still haven’t figured out how to do a bench turn on. I did manage to get readings off the main 14 pin connector by shoving skinny leads into the back openings of the plug. Everything looked normal with that...

Oh no I def know it’s for a Mac. It’s a PM6500. I have the same question over at r/VintageApple. So far no answer.

Close ups of the connectors. I think it’s probably on the smaller plug because the PSU won’t power on with the keyboard unless this is plugged into the computer.

Trying to figure out which two pins to bridge to get the PSU to turn on so I can check output voltages. (If you can point me to a whole pin out even better!). As I’m sure you all know, for more modern PSU’s you simply bridge the green wire to a black (GND). There’s no green wire on this PSU...
