And, here are some more, including the addresses in Don's posting:

(Addresses to PAiA; don't know which one is right...)

   PAiA Electronics, Inc.
   P.O. Box 14359
   Oklahoma City, OK  73113
   Phone: (405) 843-9626

	PAIA Electronics

	Edmund, Oklahoma 73013
	(405) 340-6300

Just read Emusic-D, and a week or so ago I received in the post a new PAiA
catalog.  Now I know that PAiA seems to have a bad rap 'round here but,
FYI - they have listed a number of CEM chips for all us DIY types.
CEM 3310 ADSR
CEM 3320 VCF
CEM 3330 DUAL VCA
CEM 3340 VCO
CEM 3360 DUAL VCA
CEM 3379 Voltage Controled Signal Processor
         (4 pole low pass VCF, VCA, 2 chan VC pan)
CEM 5508 OCTAL SAMPLE and HOLD

all come with data sheets

Actually, interestingly enough, some of older Curtis chips are a few bucks
less expensive from PAIA. Curtis is selling all their chips for $15.00,
regardless of functionality, PAIA had some of the same chips for under 
15.00. 


Regarding the Curtiss IC's, there are three possible sources in the US:

	PAIA (Oklahoma) - Synth Mail-Order outfit
	Wine Country (CA) - Sequential spare parts
	On-Chip Systems (CA) - Formerly Curtiss Electromusic (CEM)

     On-Chip Systems
     1190 Coleman Ave.

(On-Chip systems have data sheets for the following:)

CEM3310 CEM3312 CEM3320 CEM3328 CEM3330 CEM3335 CEM3340 CEM3350 CEM3365
CEM3372 CEM3374 CEM3378 CEM3379 CEM3387 CEM3389 CEM3391 CEM3394 CEM3396

The distrubutor in Germany is: (for On-Chip systems)

   Some synths, like Prophet 5, use Curtis chips. I would like to know
   the address and fax of this company. I hope someone of you can help me, 
   sci.electronics didn't and Curtis chips are not available here in Finland.

Below is from a couple postings on rec.music.synth a while ago.

Try PAIA. I just got their catalog, and they are carrying the 
CEM chips again.  Their address is:

PAIA Electronics
3200 Teakwood Lane
Edmund, Oklahoma 73013
(405) 340-6300

----------------

CEM chips are also available from:

Doug Curtis
On-Chip Systems
1190 Coleman Ave
San Jose, CA 95110
(408)-988-5400

Out of curiosity, I called this number, and indeed, they are!  Doug
Curtis is the founder of Curtis Electromusic, and the entire CEM
line is still available, and they will sell to hobbyists in onesies
and twosies.  For quantities less than 100, the price is $15 per
chip.  The numbers available are:

CEM3310 CEM3312 CEM3320 CEM3328
CEM3330 CEM3335 CEM3340 CEM3350 
CEM3365 CEM3372 CEM3374 CEM3378
CEM3379 CEM3387 CEM3389 CEM3391 
CEM3394 CEM3396
