[Coco] Downloading software from Larry Greenfield's site?

First off, I piggybacked 4 sets of 41256 memory chips leaving pin 15 free on the top three rows and soldered those to the Disto board. Solder a wire from pin 15  to each memory chip on that row. You will have 3 nicely connected rows of wire-wrap wire. Then on one of the collumns of memory, solder another wire to pin 15. About 2" length, so you end up with a wire connected to eack row of RAMS. With the cartridge connector facing you, you will see a 74s139 directly in the middle of the board. Immediately below that chip are 4 pads in a row. The left one is for the first row of rams (the ones directly soldered into the board. The second pad is for the fist row of piggybacked rams. The third pad is for the third row, etc. Then just modify the OS9 descriptor, and your set.
 
Good luck!

O.K., I'd like some information on that. I have 768k in mine. (And a few
"spare" 256k chips.)

No, but I do keep hoping.
