Hi,
I have a 2001 with 7x 2316 ROMs.
I want to replace them by 3x2532 and a 2716 for edit-rom to build in the
bugfixed Basic with floppy access ;)

After watching the schematics it should be possible:

I have to put the 4k-eproms in H1, H2, H4 and a 2716 in H3.
Pin 20 / CE is the same (for C / D / E / F - segment).
+5V goes to Pin 21 / VPP.
BA11 goes to Pin 18 / A11 of the 2532 and selects the upper or lower part.
The 2716 has a second CE at Pin 18 and will be only activated from E000-E7FF
(BA11).

Has anyone tried this?

greets
Christian
