Here's the link to Rob Krenicki's GitHub project page: https://github.com/rkrenicki/Tandy-EX-HX-3in1
This is pretty much the only upgrade board you need for the Tandy 1000EX & HX machines. The single board provides 640K main RAM + 96K of UMB RAM, a full speed, buffered 16C550 RS232 port and an XT-IDE CF 'hard drive'.
I believe Rob is sold out of his latest batch of built boards & kits, but I still have about 20 more partial PCB kits available that include both PCB & rear panel plus the two special connectors required.
If you'd like to build one, there's a listing in the Marketplace forum with photos. If you have any questions about the project, post here and I'll try to answer them. You can also contact me off list at drlegendre@gmail.com.
