Can this be used?

I salvaged another VF drive from work and got something called an HMOS controller from it. Can it be used in any way?

It's an intel P8798

That has on-chi[p ROM. This means that you won't be able to reprogram it.

Thanks Steve. It still looks cool sitting on my desk. Makes a great conversation piece too.

That is true for the P8398 part but the p8798 should have a quartz window that when uncovered allows an EPROM eraser to erase the contents. Then with the proper programmer, it can be re-programmed. The E in EPROM stands for Erasable. True of most, if not all of the Intel processors and memories, as well as those from other manufacturers.

Looking at the datasheet again, it does list the 8798 as both "user programmable" and "OTP" (one time programmable).

Since it mentions EPROM, if the device has a quartz window you can likely erase it, otherwise not :-(
