Thought I'd post this eBay auction here too given the audience. I'm getting rid of my old trusty power IIgs setup. I haven't really used it in years, but it's all working (sold as-is).
ROM3 IIGS (Woz case) with an overclocked TWGS currently running at 14MHz (w/ 32k cache board too). Also has a GS-RAM II 4MB card and an AE Heavy Duty power supply. AE 3.5" drive included too, which I think is a high-density drive, but I don't know much about that one. There's some other stuff and some floppies that were in the box too:
RamFAST rev D + external HDD in enclosure with cables. Working pull from the IIGS above with System 6 installed:
Both auctions sold as-is. PM me at here before tomorrow afternoon if you have any questions about either of them.
