Hi!
I don't have a source for the Am29F032B in SO44, but the board layout
for the 32-bit processor that I made also has an Am29LV017D (2 MB) in
TSOP-40 package. It interfaces to the C-64 and can be used as a
cartridge as well. (I do have some Am29LV017D chips.) The board is
expected to be manufactured in about 3 weeks.

Subject: Looking for one Am29F032B in SO44 case
Hello all,
Good news for those who remember my almost two years old vaporware
project,
constructing an "all-in-one" cartridge for the VIC-20: the hardware of
the
prototype seems to work fully, and the only thing missing is some 6502
and
C software for programming the Flash ROM while the cartridge is
connected
to the VIC-20.
The prototype has only 512 kilobytes of Flash ROM (Am29F040B), which is
not
enough for storing all VIC-20 software, not even for just the cartridge
games.
I've found out that there are 4-megabyte 5-volt Flash ROMs. The one
from AMD
looks very nice, since it is available in an easy-to-solder SO44
package, and
the address and data buses are nicely organised on the package. I've
already
designed a board layout for this chip (Am29F032), and I've found out a
source
for n*17 chips, n>1. However, I would like to build a prototype first,
and
I need one chip for that. Can anyone help me?
If not, I guess I'll take the risk and order 34 or 51 chips. I'm a
little
worried, since the C2N232 hasn't been a great success (only some 90
devices
sold so far), even though it works on all Commodores equipped with a
cassette
port. This device would be specific to the VIC-20, and it would cost at
least
twice as much as the C2N232. How many people would be interested in a
VIC-20
cartridge that can store all VIC-20 software in an easy-to-access menu,
if
it costed some 40-50 EUR or USD? It would be available by the end of
this
year if there is enough interest.
