Compucorp / Monroe 325 Scientist
Hi everyone..
Long time vintage electronics nerd here.. In my hunt for old gear, I recently stumbled upon a Monroe-branded Compucorp 325 Scientist with a 392 tape drive unit.. Ive googled the heck out of this thing and have found one or two pages with some details, but it seems the units themselves are a little sparse these days.. Havent been able to find any that have sold on the big auction site in the last couple years. I guess Im wondering if thats the best audience for it or if this and other? forums exist and would have some sort of valuation or interest.. Thanks, frasertech |

Hello!

I am pretty sure that there is an audience here for Compucorp/Monroe calculators. It has at least one member (me) :-) Congratulations for your find, these units really have become extremely rare. On different eBay sites in Europe one or two (in total) show up every year. I stopped looking at eBay in the States because the shipping charges, especially for items as large as your 325, have risen to astronimical figures over the last years. Myself I have a complete (?) collection of the "pocket sized" Compucorps (320G, 322G, 324G, 326G, (340), 342, 344, 354 Surveyor, 360 Bond Trader). About the 340 I am not so sure. The Surveyor and Bond Trader models took lots of patience to find and the ones I have were actually the only ones I ever saw on eBay. Twenty years ago these calculators could be found for junk prices (I paid less than 10 Euros for some of them - in times when an HP67 would already cost over 100 Euros) but now even broken or incomplete ones fetch well over 100 Euros. Soon there will be none left. I really like these calculators because of their incredibly solid build, their excellent keyboards and the most beautiful display of any calculator ever made.

Thanks for the reply, Max.
Yes, I sold a couple auto parts to a gentleman in France a few years ago and when I started looking for shipping costs, I emailed him asking "Are you sure about this?" haha. Glad to hear they're not an abandoned brand by fans. I'll get it cleaned up and give it a test, I suspect the belt(s) have gone away in the 392. thanks again, frasertech |

I succeded only once in winning an auction for a 325, but it never materialized in my postbox. :(

There is a lot of information about CompuCorp and its various models of calculators at the following sites. This includes pictures (inside and out). Their amber 'Panaplex II' gas discharge displays are quite nice. Although they are not pocket sized, they were hand-sized portables, ran on batteries (four D cells) and some of them were programmable (with optional tape storage) about a year before the introduction of the HP-65.
