Got this thought experiment that might work? Maybe. What if you used a RasPi in the place of a XEP80? First, hook the RasPI to the Atari from the joyst port to the USB. of course that would require some sort of parallel to USB interface which is beyond me. But say IF it could be done... Second, the RasPi could be programmed to send the info through it's HDMI to a current LCD TV with glorious simulated 80 column text. might be able to use the XEP80 drivers. of course the first part with the interface is (insert magic here). I'm not a hardware guy but the software sounds doable. Any thoughts?
Here is a working, hard to find 80 column display card from Newell Industries called the Ramrod. Paper manual and installation instructions included. This card replaces the OS card with a OS B, The fast math ROM, and your choice of Omniview, omnimon, or 4KB SRAM in the address space of c000-cffff. Incliudes the Omniview 80 column display rom add on. Toggles on in basic or DOS by jumping to address C000 or calling x=usr(49152). You can also swap that rom chip for the Omnimon for assembler/testing/cracking. Included is 2 2KB SRAMs it you want to use that 4KB space for programs. The display looks best using a monitor that uses separate luma and chroma and plug in only the luma. Manual and documentation on archive.org Free flat rate shipping USPS to the US.
