Stick in there with the old stuff, I just got an mc-400 for £5 at my local car boot, a couple of years ago I picked up a Nascom 3 for £2 with twin disk drives (and a nice Lucas badge on the 'blow molded' case) I have an attic full of Apple 2's and 68k Macs (including an apple 2 clone that just comes up with "computer" on the boot up screen rather than Apple).
I hope that it will all be worth something one day.
