I am "getting out" of the Tandy EX/HX game, and I am doing one very last run of my Tandy 1000 EX/HX 3-in-1 Upgrade Board. These boards are an all-in-one upgrade solution for people who just want to play XT/Tandy era games, and it provides the following upgrades:
640kb System RAM
96kb of Upper Memory for DOS and Drivers
9-pin RS232 Serial Port for a mouse or communications
XT-CF-Lite Interface for storage
My price is $115 direct or $120 on Tindie plus shipping and they include a preconfigured 32mb Compactflash card.

FAQ:
Q: Does this have DMA?
A: This board does not add a DMA controller, which was only included on the Tandy board to handle DRAM refresh. My use of SRAM here means that it does not need external circuitry to handle refresh. It is a common misconception that DMA "speeds up" an EX/HX system, when the speed up is actually from having more memory. The on board IO does not take advantage of the "Direct Access" portion of DMA, so it will always run at PIO speeds.
Q: How much memory does this give me?
A: With the memory map of the Tandy 1000 EX/HX it expands the system to the maximum of 624k Conventional RAM, and also adds 96k of Upper Memory Blocks. With the supplied drivers, loading DOS 5.0 high and the Mouse Driver high, it gives you about 610kb of free Conventional RAM.
Q: Can you include a Network Card/Adlib/5 Serial Ports/VGA/3D Accelerator/486 upgrade?
A: My goal was always to make a single board to bring a stock Tandy 1000 EX or HX computer to be able to play as many of the of the Tandy Graphics and Sound video games as it can. I feel that the system is not fast enough to properly handle things like Ethernet Networking, and VGA and AdLib would take away from my goal of Tandy Graphics and Sound games.
Q: Why does this not have an ISA Slot/Passthrough connector?
A: I intended the board to be the only expansion card in the system.
Q: Didn't I see this board on YouTube/Facebook/some other place?
A: Indeed, you probably have! Adrian Black reviewed one of my later prototype boards, and I have been selling them on Facebook for the last few months.
Q: Where can I see Adrian Blacks Review?
A: https://www.youtube.com/watch?v=yESy...igitalBasement
Q: I think your board is crap, and I only want everything you listed you would never put on there.
A: Please feel free to take my design and add on the functions that you wish. My design is fully open source, and I encourage you to modify it to your hearts desire.
