Value of a PDP/8?

Thanks for the replies... I should have guessed at the value of a 
Straight-8 given I too have never seen one for sale and their form is of 
somewhat iconic status.

An 8/E would seem much more pragmatic, and the cost from a reseller if 
still stocked and not risen too much pallatable. Will look into it more 
and the benefits before decided to part with other kit.

Incidentally the first computer I owned (a 2U high PDP11/03 IIRC) had an 
RX02 drive. Well, it actually came with some RL drives too but my dad 
reckoned mother would kill both of us if we brought those back too. The 
whole lot (with lots of floppy, RL and tape media, and docs) was 50 
UK pounds from a radio amateur rally (when I was 14yo, around 1989). As 
it happened the machine had to go anyway - every time I accessed the 
floppy drive the motor interfered with the TV downstairs and I got 
shouted at! But was way cooler than my dad's Amstrad PCW8512...
