I found a site with specifications of a device that allows printing to a USB printer from a parallel printer port. It doesn't offer them for sale, the site has schematic, Eagle files, and ATmega16 firmware. The designer allows cloning of the device, but requests feedback for assigning serial numbers. http://www-user.tu-chemnitz.de/~heha/bastelecke/Rund%20um%20den%20PC/USB2LPT/lpt2usb.en.htm It doesn't translate the protocol so the printer in question must be able to handle that used by the source, I believe the Epson FX protocol would be the best option for the Atari8 line. IBM has a webpage with a database that can be checked to see which printers support this. A similar commercial device is available for US$69.00 from http://www.lpt2usb.net/
I have a Panasonic KX-P1123 24-Pin Dot Matrix Printer for sale. The picture below was taken with the installed ribbon so the characters are not solid black. However, I bought a still wrapped ribbon and will include it. eBay looks to have enough stock of the ribbons to last some time. This printer uses a Centronics (Parallel) interface. Thanks for looking! Maybe your ASCII art be beautiful and code listings be free of bugs. http://r.ebay.com/UBlJh4
I have an Atari 7800 that I've modded for composite video. Now I'd like to start learning how to write software for it. I'm already familiar with 6502 assembly (from the NES), but will need to do a deep dive into the MARIA chip (so far, how you access this seems crazy! ) and any other idiosyncrasies of the 7800. My question is, after writing and compiling on the PC (Windows), is there a way to run/test what I write on the real hardware? Or am I limited to running/testing in emulators on the PC? Something like a cartridge with a serial cable connected to the PC where I could compile on the PC and update the cartridge via the serial cable would be wonderful... does anything like that exist? I just had a vision of a Raspberry Pi Zero W in a 2600/7800 cartridge case connected to the PC over WiFi... LOL!
