(48SX) TDS Card bank switcher?

[greg1975]

Hi all,

I'm new to the site. I have an HP 48SX and am looking at the older TDS cards. I'm wondering if anyone knows where I can get a copy of the TDS bank switcher program that I'll need to access >128K on their cards. Does anyone know? I've searched here and hpcalc with no luck. I *think* it's called "SWITCH", but I'm not sure.

Much appreciated,
Greg
