I presume that you are looking for the Aero 1550, the black and white
PDA that is common for use with the GPS system.

Although there aren't any now, look at www.ebay.com and do a search for:
compaq 1550.

They sell for about $35 to just under $100.

etc. and be willing to part with your 1520 (and it's still in good
condition), please let me know. Thanks, Gary
