[For sale] HP calculator collection, modules, & accessories

[gspnz]

Hello,

I need to decrease the size of my collection so I have a number of items for sale, including 13 HP calculators, a variety of HP-41 peripherals, HP-41 ROM modules, and HP-71 ROM modules. I'll paste in a preliminary list of items below.

All of the items are being offered exclusively to this forum before putting them up for auction elsewhere, as I'd really like them to go to fellow HP collectors and users. I'll consider all reasonable offers.

Please PM me about the items you're interested in and I'll send back more details, including pictures. All have been stored without batteries installed and should be in full working condition. Many items come with slip cases and/or original packaging. I'll confirm status and condition before making a deal on any particular item.

Please see below for the list.

Thanks, Gary.
