I also have websites for two much more rare Wang machines, both predecessors of the 2200.
The 3300 was intended to compete with PDP-8s, and has a nice front panel. It supported up to 16 users, and could run BASIC or FORTRAN. The emulator comes with an image of the BASIC interpreter; alas, I don't have a copy of their FORTRAN. The machine had a reputation for poor reliability. Supposedly when the 2200 became available, Wang offered all 3300 customers to swap their 3300 for a better 2200 system.
As far as is known, one system ended up in the garage of a guy in Belgium. Unfortunately he passed away a few years ago. It seems likely that computer got scrapped.
This was a Wang calculator had its microcode rewritten to be a word processor. The machine had 256 bytes of RAM (originally core, later replaced with RAM chips)
