|  Re: How much ROM is faster than RAM
RAM's are faster than ROMs for a long time. From the early 90s (or late 80s) when CPU clocks (1 cycle) were faster than the typical access time of memories it became a factor to quicken memory access so they started using the so called shadow ROM (copying contents of ROM to the underlying RAM area and).
In case of the plus/4 RAM and ROM access are both quicker than the CPU cycle so their access times are indifferent, you won't sense any difference (as the former posters said before)
