Re: IJK interface diagrams.

... Dbug (because he showed interest) and - if interested - kenneth and Silicebit. (for their help with the interface) would have priority on the waiting list. So only one unit would remain for someone else... Thank you very much for your offer, HigashiJun, but I'm more interested in the Protek pro...

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. :-)
