Y'know I bought the Mac Plus off a guy on TradeMe reasonably cheap a while back, it was missing its mouse and miraculously one of those showed up by itself a few months later... but I've never gotten to the point of actually trying the thing out. Maybe it's all the scaremongery from you guys about blowing caps!
Of the whole collection, the 68k Mac that gets the most use is the 580CD. It's had some upgrades done and runs really nicely, has real Ethernet, the whole nine. I use it for keeping an eye on IRC while I'm messing around with Amigas.
Oh yeah, there's a bunch of Mac monitors here too that go with the machines. I've got a 13"ish one that matches an LC II, a multimedia 15"ish dealie that went with one of the PowerMacs and a 17"ish beefy one that went with the 7600/200, it's got a Sonnet G3 card in it too so that makes sense.
I should probably have said a higher price than a box of beers now that I'm thinking about this, but at the end of the day if I'm helping out a brother in need who wants to get collecting, I'm all for it.
