This is one additional follow up. As figured out in the last post, the used memory chips (ROM and RAM) on the CPU card are likely fast enough to be used without a wait state. So the idea is, to run my tone generator and maybe the floppy drive rotation measurement in the RAM on the CPU card.

As described in the last post Intel 8085A timings it has been established that it is very likely, that the Alphatronic P2 introduces a wait state for accessing RAM and ROM. The numbers seem to fit.

This post is a follow up on the last post about Alphatronic’s P2 CPU speed. I created back then a sound that was supposed to be exactly one second long, but it actually was 1.28 seconds long. So, something I was doing wrong…
