ZX81 Compatible "Printer"

Hi,

I wanted to say that I built a "printer" for the ZX81 that plugs into the expansion slot. It is built around an ESP32 Arduino-like board that interfaces with the ZX81 through some 74 series logic gates. The microcontroller stores whatever is printed in memory and shows it on a simple web page. It would be quite easy to add the ability to send the output over, say, RS232, to some dot matrix printer, but I don't have one. This is the link to the repo, that contains some more info: https://bitbucket.org/staffanulfberg/zx-wifi-printer/
