Re: HP48 Cogo Card - Worth Anything? Message #2 Posted by Reth on 19 Aug 2012, 6:03 a.m., in response to message #1 by JamesT
I strongly doubt there is any interest in them, I have also seen those ridiculous prices - unless as a collector's item practically they are worth nothing. Just about every surveying instrument today has on-board software covering everything these cards do and heaps more. If not for nostalgic reasons I'd have sold my pristine last series HP48GX with 2 Klotz RAM cards, cables and the printer (still with the 2 original boxes thermo paper).
