Subject: [AH] MKS-80 Revision #


hi,

I am looking to buy an MKS-80 for a friend of mine. I've found a good deal
with serial number 542614. Can anyone tell me which revision this is? If you
can't tell by serial # is there any other cosmetic aspect that gives it away
(i.e. not the sound of the filter).

Thanks a ton,

Shawn Cleary

There is a mention here of which serial # Rev. 4 went
up to and where Rev. 5 began. 

Cheers!

Anything after 511800 is "MKS-80" ver 5.O".  It was after they stopped
using the CEM3340 VCO's, CEM3360 VCA's, and IR3109 VCF (which was same VCF
as the Juno 60 and SH-101, later MKS-80's used a combination VCA/VCF IC
with less resonance).  I don't know of any cosmetic differences, although
they might exist.

To tell the CPU PROM version, hold down Auto Tune and Write on power up.
