I am working on putting together the parts for a Z80 based single board computer. Small memory in DIP type chips is now 128Kx8bit devices. For ram this is no problem, but for Flash Prom it makes it difficult because I have to use 17 address lines in programming and erasing. Nothing to exotic about it, but was wondering if anyone else had tried this.
found a better developed discussion of the same topic here -

So that would be the place to go.
