Wide body CEM parts

Several people have asked for the 600mil (wide body) CEM 339x parts used in some Oberheim equipment. I do not have any. I asked OnChip, and they did this as a "short-term" fix for Tom O. All later models used the standard 300mil stuff.

Sorry for not relaying this earlier. If anybody has placed orders specifying 600mil, please email me ASAP so we can discuss what to do.

I can easily fabricate 'adapter boards' to do this, but I would need at least 75 pieces total (from everybody) or more to make it worthwhile.

Here is the current list for those not yet requesting.


Orders will start shipping out on Wed or Thurs (waiting for nice shipping cartons to arrive!)

CEM Chip Availability  14 March 1997


The following parts are offered for sale in order to fund the
re-issue of the CEM3340 and 3310. If enough of these existing
inventory parts are sold, the 3340 will be made available in
mid-summer with UNLIMITED quantities. Then, proceeds from the
3340 sale will fund the mask set for the 3310, and possibly one
other chip (3328 or maybe 3394).

Data sheets for these devices, as well as other interesting
synthesizer info is available at the CEM website:


Lastly: people have been asking about the SSM chips, and if
they can be reissued. We are undertaking steps to try to see
if this is possible. However, at this point is is unlikely.


The following parts are priced as follows:

2-3       $15   <<<NOTE: 2 is the minimum order <<<
4-9       $14
10-49     $13.25
