I’ve been watching a Meyer Sound SIM 2 machine being auctioned on eBay.
Having recently taken Bob McCarthy’s class and asking a few questions, I know that SIM 2 uses a keyboard only (pre mouse) and so everything is done with key commands. Having grown up with DOS, this isn’t as scary to me as it might be to a younger person. Meyer Sound always provides a lot of good information in their user manuals and I couldn’t find a manual online for SIM 2 so I wrote Meyer to ask. Voila!
