Announcement SWISSMICROS ALERT!

4 Upvotes

Just an alert to anybody who may not know about Swissmicros's new website or their RPN/RPL calculators at all, they're currently being sold on their new website on this link right down below. They have limited stock, so get yours before they run out, though I believe they've restocked a good amount recently. They're currently the best physical Scientific RPN/RPL calculators on the market beating out old classic HP Calcs in their reimaginings with more features and capabilities then ever before with a lot better hardware. They are pricey, but they're of very high quality.

FYI: They may sometimes have hardware issues upon receiving the calculator, shipping may wreck it, handling may mess it up somehow, maybe the producers themselves had a faulty piece..either way, if you have an issue, contact them, they'll be very glad to get you a refund, or replacement/fix @[[email protected]](mailto:[email protected])

One of the hp48 is the one i bought new in 1995 during high school.

My deepest sorrow is that im unable to find memory card for cheap.

Question Casio fx-350EX or Canon F-789SGA?

3 Upvotes

I'm a civil engineering student (freshman), and I'm currently stuck between these two calculators. I can't decide what to choose because they both have pros and cons. Casio is faster, meanwhile, Canon is more advanced and has many functions. Help me choose, please T_T

So over the last couple years I’ve been buying cheap busted up Voyagers (10s, 11s, 15s, and 16s) and replacing the screens with those from donor 12s. I finally put them all together in one place and realized I might have gotten carried away :)
(The 10C in the upper left is up next, but it’s a black diaper, which are harder to swap and harder to find donors for.)
