My proms are the TESLA brand MH74S571. I also have a set unprogrammed TESLA proms which I bought earlier.
The AM9111 RAM chips have arrived from Israel and are working fine.
I also got two 80C95 (instead of the hard to find 80L95) from littlediode in the UK and it works fine too.
From Martin (the Czech guy) I got the tip I could also have used the 74LS365 instead of the 80L95. Ah well, my MK14 is complete now
