Re: Cumana disk interface problem
If you made the measurements between the pins 10 and 20 of LS244's, I think that 4.4V - 4.5V can be usual. For LS93 3.9V is strange. For LS224's, I can see each pin 10 (GROUND CHIP) go to resistors R1, R2 and R3 (GROUND rail). Note that for LS93 pin5 is VCC and pin10 is GND. You must adjust RV1 too.

Re: 65c22
Hi Vyper68!
You can use the R65C22P2/3/4, the R65C22 is fully compatible with NMOS 6522 devices, The /IRQ output pin is an open-drain configuration, so no problem.

Re: 65c22
The W65C22N is designed to be compatible with 6522, you must order the W65C22N not W65C22S. From The Western Design Center: W65C22S/W65C22N Differences The W65C22S is lower power, faster and direct drive outputs with no current limiting resistors on outputs ports. The W65C22N is plug replacement of ...
