Can anyone provide me the exact part number of the 27C512 inside Behringer? I haven't opened mine yet. I'd like to know the speed grade on their device
Typical HOLTEK semiconductor 70 nsec CMOS 64Kx8bit OTP EPROM.

Actual part number HT27C512-70 in a plastic 28 pin DIP.

The BLURB.

* my feeling is that a fair number of people would have trouble swapping this chip out. It isn't really entry level. Getting the hard glue off would be a challenge. Then, removing a 28 pin dip and reinserting it without bending a pin or the socket would be tough for many. It ain't a PLCC socket. Large DIP sockets are tricky - not to mention ESD on old CMOS.
