I think a record has been set for Expansion RAM prices. A Microbotics Starboard II with 2Mb of RAM (only - no clock, etc.) just sold for $204. and change - plus shipping on eBay!
Yeah and just think of how stupid the idiot was who bought the Starboard new and then fully populated it with DRAM! LOL!
... I still use mine everyday so that I can recover my expenses from 1987.
