This is a "3-in-1" Upgrade Card for the Tandy 1000 EX and HX computers. It adds the following functions to these computers:
Many of the EX and HX computers available today do not have the Tandy memory expansion module, and are limited to 256kb of system RAM. The non-standard expansion slots in these computers make expansion more difficult than a normal Tandy or other IBM-compatibles. My goal was to create an expansion module to maximize the Tandy 1000 EX and HX systems to play games designed for Tandy Graphics and Sound. It does not have provisions for any advanced functions such as VGA, Ethernet, or AdLib sound, it is only intended to add the functions above.
My board is based on several other open-source hardware projects, and has been pre-configured and optimized for the EX and HX computers. It will not work in any other Tandy model without extensive modifications. It is fully open source, and the link to the repository is below.
Fully Assembled boards now automatically include a preconfigured CF card, as nearly every order has added one.
I offer the board both as a Fully Assembled and Tested board, and as a "Parts Reduced Kit". The Parts Kit consists of the following:
