ROM speed suitable for H5?

I am just wondering, since EmuTOS keeps getting updated (and I like to keep up to date if possible) Do I need to keep writing one-time-programmable 27c4096 chips (55ns) or will the H5 be happy with 120ns 27c4096acc-12 UV erasable roms?
ps - as a side question, is there any such thing as an e-eprom variant that doesn't need UV erasing?

The H5 will work fine with any chips. You do need 100ns if using the 16MHz booster. 55ns is for the STE when running 32MHz.
Things will be easier if I ever get flashy clock finished :roll:

I'm using the TOS Decoder (your little one which can also be a 16mhz booster) & TF536 50mhz 030 - will that be ok for 120ns?

Should be.
