Sorry to bear bad tidings, but there isn't, and probably won't
be, a 28 pin 1Mbit EPROM equivalent to 23c1024. The mask rom
is only feasible because it doesn't need a Vpp pin for programming,
and it has only one control pin (OE) besides the 17 address pins.
There is the remotest possibility that someone might make the OE-
pin double up as Vpp/program enable, but now the 32 pin pack is
established, that's unlikely. Looks like you'll need to make an
adaptor board, or bend some legs.
