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.
