Anyone with a TashTalk USB want to test this one for me?
https://classicstack.app/ - it's a port of my ClassicStack AFP server and client to typescript. You'll need a browser with Web Serial support (Chrome or Edge).
Open the webapp, press "Connect TashTalk", and select your TashTalk USB. You should be able to see "ClassicStack" show up in Chooser --> AppleShare. Use the Guest login.
If your Mac has sharing enabled, you should also see it show up in the LocalTalk section and you should be able to connect and mount your Macs volume.
MacBinary, BinHex, SIT and ZIP files are supported for upload and will be decompressed on the way over. Downloading files will come back as .zip files with AppleDouble files.
