I'm studying chemistry at UW and about to take a stats class (one of the reasons for extra space). Will the card transfer program still work without a COGO card?

I have the HP Serial Interface Kit on a floppy (version 1.01) that should work just fine for you. If you need a cable I have an extra one you could have. My email address is mnhollinger(a)yahoo.com. Send me your mailing address and I'll get those items out to you.

Try this address: > mnhollinger_at_yahoo.com. I took a look and found a HP Serial Interface program here: http://www.hpcalc.org/hp48/pc/link/link48.zip Is this the same one that you have? I just wanted to make sure I couldn't find what I needed online before you took the time to send something to me :-) Thanks for all your help!
