I salvaged a nice little pc board that houses 6 eproms, all the
data,address lines,vcc,gnd lines are connected already, with the
addition of a LS138 selector thats tied to each /ce of every eproms.
MY application can only read one eprom at once, so, is there a way I
can devise a physical switch to connect to the LS138 or otherwise to
select each eprom individually & sequentially? in other words, when I
would press the one switch, I would select the 1st, 2nd, 3rd .... 6th
eprom, and maybe just put a LED for each eprom to display which one is
being accessed. IS this possible?
any ideas, suggestions ..links, schems much appreciated..
THanks
