Hi. I had similiar problems with a brand new DE1 board. However,
version 13 runs with the older spihost.rom from 12e!! I have no clue,
what the problem really is, but obvious somewhere around the spihost,
Z80 emulation..?

I had 12e on it.. it runs, but from time to time, it 'sees' key
pressed (F12 menu pop ups, selecting adf file, RESET!).. so actually
ist not useable..?? This behaviour ist gone with 13.. But 12e runs
just fine on an older DE1!?

Whould be interesting, if you could confirm these observations..

Regards, Peter
