First attempt with replicated pcb, and commands are not working. There comes I/O timeouts for _VP commands.

You are doing a good job, I am looking forward to the final effect of the interface. And I am ready for it, if you have a PCB for sale, it is a reservation for me.
I have HC95 and managed to get Storm (but no casette)

Damn, I missed that I had put Intel 8255A( not rated 5mhz), when in original PCB there is Nec 8225-2(rated 5Mhz max). So the speed is not suitable. But my only nec8255-2 ics from AliExpress seems to be faulty or fake. So have to wait for other source now from eBay(nemoclock seller).
