Xpantastic!

Hello, finally got hold of an xpander last week, absolutely love it. Some of my first sounds out of it here: http://soundcloud.com/t1b/sets/xpander/

Im not really a vintage chap but I make exception for the XP, always amazes me that no-one has ever really topped it in the 25 years it has been out. I guess the andromeda came close but since its not a desktop synth and looks like a mid 90's car stereo Im ruling it out.

Anyway, Ive a few questions:

CEM's- anyone know of anywhere with a few spare VCO and filter chips. Is that all I should be stocking up on or is there anything else prone to faliure?

OS- Im not on the most recent OS (think Im on 1.0 and 1.2), everything is running perfect so Im tempted to leave as is- is there anything Im missing out on by not upgrading? Was it just a bug fix upgrade?

Manual: I have a PDF I can print though I was wondering if anywhere stocks printed & bound manuals?

Cheers,

Andy/tIB/sonofprent
