I am having problems getting enough information to
make my Emulex
SC70 masbus disk controller work. If I have to repair it, I'm will
be in serious trouble. I doubt that I will be able to locate a
schematic given that I am having so much difficulty locating just
If it uses standard chips (i.e. data sheets exist), then it can be
reverse-engineered!
a manual. The SC70 uses a 16bit 290x bitslice
processor, so after
those parts are no longer available, even though it would trivially
fit into a small FPGA of the time, and even if the logic levels are
compatible, reprogramming an FPGA to do what the 290x does will not
be a trivial task.
OK, the 290x chips are not simple, but data sheets exist, so it should be
possible to make an FPGA do the same thing.
Just imagine trying to repair all of the proprietary components
in a PC or even the CAD program dongle 50 years from now.
I knew there was a reason why I stuck to classic computers ;-)
