August 2, 2016 – TRS-BOX on any TRS-80 with a RS-232

Pete Cetinski has improved his TRS-Box so that it now works with a serial port.

TRS-Box is a Dropbox client for the TRS-80 Microcomputer. It allows you to navigate and copy files from and to your Dropbox from your TRS-80.

Trs-Box used to require a TRS-80 Model I with MISE or a TRS-80 Model III or 4 with M3SE, but Pete has gotten it to run on any floppy or hard disk enabled TRS-80 which has a RS-232 interface (although will need to buy a serial-IP adapter).
