If I were to buy an LED model...

[Dave Britten]

Update!

I bought a very nice 25 from DaveBr, with the case, manual, and applications book. I've been tinkering with it off and on all afternoon/evening, trying out various programs from the books and such. It's really impressive how much you can do with just 49 steps, and no subroutines or indirect addressing. Yes, you can do more with a 42S, but you can still do a lot with a 25.

I got a set of 4 flat-top NiMHs from Batteries Plus, so I can have two ready to go if I need to throw the current pair on the charger. They seem to fit well in the little 3D-printed battery pack.

I didn't realize how tiny the Woodstocks are. My TI-58C looks gigantic next to it.

I was able to write the usual mod 30 prime factor finder on it, but without subroutines, you instead have to build a loop that strips digits off of a "stream" of offsets stored as .2122 and .42424626, and it ends up being slower than just testing all the odd numbers.

I still plan to keep an eye out for an 80, and maybe a Spice too.
