Re: Studer / Revox etc BiPolar PROMS! Question and concerns!
I don't know if this will help but I've found a number of what I assume are unprogrammed PROMs. Not the 123s but possibly an adaptor could be made.
The PROMS which may be useable are
N82S181N 24 pin 1024 x 8
TBP28S42N 20 pin 512 x 8
TBP28L22MJ 20 pin 256 x 8
plus N82S137N 18 pin 1024 x 4
If these are of use let me know as I have no use for them and no means of checking or programming them.
