Sequential circuits samplers

<< As far as I know, it can't be duplicated on any known computer, nor on

machine capable of creating them is dead and gone. >>

what *does* it do on power-up?

I've never heard of this diagnostics disc, and I'm reasonably confident that 
tim wallhead (used to be the service engineer at argent's in london, where I 
bought my 2002+ and found a mellotron....) would've told me about it while I 
was raiding their 2000 library, if he thought it was useful. I don't think it 
would have been for system checks anyway, more likely it was for adjusting 
the analogue circuitry, i.e. a bunch of waveforms, with the patches set up to 
check open and closed filters and amps, crosstalk, the mod depth of the lfo 
and stuff like that. 

the o/s is either working or not. somewhere I have an old eprom with v3 on it 
but it's unlikely to help much, besides being not the latest version.

anyway, the 2000/2002 should make noises based on it's rom waveforms even if 
there isn't even a floppy drive in the same room. and if it's not the rom 
(which is quite unlikely, as has been mentioned) then it's most likely to be 
the system clock (the crystal that runs the whole machine; my sx16 has got 
through three before I gave up with it) or the cpu that's been fried. 

wine country ought to be able to help- they seem quite happy to enter into 
lengthy dialogue over these machines. sadly, though, many of the more 
proprietary bits are now permanently unavailable and my 2000, with it's dead 
kybd controller, is likely to be just a source of parts for the 2002+ now.  
:-( like you can't imagine. I loved that keyboard. you can stuff your akais 
and emus, this was a great sounding sampler.

the good bit about this is that I'll be passing on the surplus manual, along 
with some schemos when they arrive, to another list-member (hi ben!) who has 
a bit more time than I to scan or whatever so you can all see them.
