July 31, 2022 Welcoming a new (old) printer (back) into my fleet: a LaserWriter II. It’s a workhorse of a printer from 1988 dressed in Snow White design language. #RetroComputing (This is an experimental post to attempt to convert a Twitter thread into a WordPress post).
MJB Cartridge Expander and 80 column card for C64
I’ve had this cartridge expander for a few years and always assumed it was commonly known about and that the ROM inside had been dumped. It seems that may not be the case, so this page is to provide the information I have about it.

Atari Portfolio Serial Interface: How To Get Terminal Software

It also has a docking slot on the right side for extra peripherals. This enables you to add communications ports that are otherwise lacking like a parallel […]
