CEM and SSM -Chips available in Switzerland

[Daniel Oberfeld]

Hi list.
I thought this might be of some interest.
I recently contacted Analog Service in Switzerland because they 
announced large quantities the famous old chips in Keyboards.
Now I received an offer:

CEM:
3320 VCF
3330 Dual VCA
3340 VCO
3350 Dual State-variable VCF
3360 Dual VCA
3365 Dual VCA
3371 uP controlled waveform generator
3372 uP contr. signal processor
3374 Dual VCO
3381 Dual low-noise VCA
3382 dito
3387 Low-noise VC signal processor
3389 VC signal processor
3391 uP controllable dynamic signal processor
3396 uP contr. dual waveform conventer
5508 Octal sample and hold
5510 fast octal S+H

SSM
2024
2044
2045
2047
2056

Prices are 40.00 DM per chip, 34.00DM if you buy large quantities 
(>100).
They also sell a Curtis Databook for 49.00DM
Are these prices fair or too high?!? Did anyone ever order directly 
from OnChip or elsewhere and can compare prices (1$ is about 1.5DM)

Also, can anyone enlight me about these waveform generator/conventor 
and signal processor chips? Sounds interesting...

And one last thing: I got no professional or other relation to Analog 
Service, so *please* refer to me if you contact them (that might be a 
good basis for my deal with them )!!

They don't have email or a web site, so here is the snailmail adress:

Have fun,
