HP48 hardware hacking -- SOIC EPROMS?

[Jonathan Busby]

I've been doing some HP48G/GX hardware hacking and I'm in need of a 32-pin SOIC EPROM. The problem is that all I can find are 32-PIN PDIP EPROMS or 32-lead PLCCs. I know I can use a daughterboard with an SMD PLCC chip but it would be a very tight fit and a real PITA. Does anyone know where to get 4Mbit x 8 32-pin EPROMS in SOIC packages, or are they no longer being produced?

Thanks,

Jonathan
