RE: HP-75 RAM expansion?
Hmm, I don't understand all these hardware intricacies, but a general question:
I thought 24 kB is the maximum RAM an HP 75 can address due to limitations of the address space. Could more RAM be managed by the operating system (without patching it)? Wouldn't a complex bank switching mechanism have to be implemented? |
