Re: 2445 EPROMs
The processor in the 2445 is a 2MHz 6802 microprocessor.toggle quoted messageShow quoted text
It needs 250ns or faster memory.
Any 27128 you find is fast enough.
Why do you think you need to replace them?
I need to replace the EPROMs in a 2445 oscilloscope. These appear to be two 27128 EPROMs with part numbers 160-1994-09 & 160-1995-09. Does anyone know the access time required for these? I am able to purchase 200ns access time 27128 but wanted to be sure these are sufficient. The existing EPROM part number is covered and I wanted to keep this intact in case I need to reuse these.
