I'd think $500, maybe a little less for the whole package, is in the ballpark in this economy.
I bet you're going to want to find a local buyer though with all that classic goodness. People often get turned off by the cost of shipping these days, especially on frivolous stuff like bulk floppy disks. Or they'll simply tell you to keep the disks, but send the hardware. :lol:
And yeah, not just for shipping reasons, but Franko is absolutely right. Unless you happen to know someone locally that could take all that stuff off your hands, you're going to be way better off parting her out. You'll end up making more money AND your stuff will move faster.
