|Casio fx-CG50||Casio-SH4||?||C810A6C066800CB_62||OS 03.60.0202||New||Manual(s)||2022-12-07||Way better than the TI-84 Plus CE; I also really like the UI since I also really like the TI-86 UI. Lending it to my brother for AP Calculus.|
|TI-89 Titanium||TI-68k||P||0412||L||2956003915||Flash OS 3.10||New||2023-02-02||Bought off E-Bay from someone listing it as a TI-86. For sure paid less than I otherwise would have, given that it's in almost perfect condition.|
|HP Prime (G2)||HP-ARM||?||D||9CJ01600FL||OS 2.1.14603||Good||Manual(s)||2021-12-25||Second Christmas calculator. Really nice to use, and I've convinced a number of classmates going into various fields in college where it might help to buy one. I hate how often it crashes.|
|TI-83 Plus||TI-Z80||P||0113||L||3444004541||Flash ROM 1.19||New||2023-03-06||I really like the flat screen, rather than it being set in.|
|Catiga CS-229||Catiga||Black||?||New||Manual(s)||2022-12-27||Funny impulse purchase. There's no serial number or anything on it, and as far as I can tell Catiga doesn't really exist on the Internet aside from selling this and the other model exactly.|
|TI-83||TI-Z80||S||1002||A||2151013438||ROM 1.10001||Good||2023-03-02||Early hardware revision, and really funky looking. Not a huge fan.|
|TI-84 Plus CE||TI-eZ80||L||0818||L||1085038097||Flash ROM 5.6.1.0012||Fair||2018||This is actually my second TI-84 Plus CE. My first one was an early revision, but was washed out after the teachers required we leave our stuff outside during a tornado watch.|
|Casio fx-CG500||Casio-SH4||?||C805A9W002680BA_E2||OS 02.01.7301.0000||New||Manual(s)||2022-12-25||I do have the stylus, but God help me if I damage/lose it. Third Christmas calculator, and probably the last unless I manage to convince my grandparents to get me an HP-50G.|
|TI-86||TI-Z80||I||0697||B||02405869||ROM 1.2||Fair||2023-02-18||My second attempt at buying a TI-86. I enjoy using it, but man is it slow.|
|TI-81||TI-Z80||I||1293||E||1220853||ROM 2.0V||Good||2023-03-02||This one is fun to see people react to because its just so archaic.|
|TI-82||TI-Z80||I||0595||R||31517791||ROM 19.0||Good||Manual(s)||2023-02-25||First calculator I bought for collections' sake, rather than to use. I do find programming for it fun and have written my own statistics suite for it. I also intend to, at some point, look at some assembly programming to add arbitrary x-value calculation for the graph math features.|
|TI-Nspire CX II CAS||TI-Nspire||M||0420||AK||4A00000278||OS 184.108.40.206||Worn||Manual(s)||2020-12-25||First of three Christmas calculators in a row. I hate how fracking slow it is.|
|TI-82 STATS||TI-Z80||Blue||S||0405||B||2091022970||ROM 1.10001||Good||2023-04-10||Literally just a TI-83.|
|Casio fx-9750GIII||Casio-SH4||?||C838B7C211317BB_62||OS 03.60.3200||New||Manual(s)||2023-04-13||I like it a lot -- I just wonder why the heck they didn't copy the History Copy feature over to the FX-CG50? Feels like a wasted opportunity and/or stupid move.|
|TI-85||TI-Z80||I||0793||C||0751815||ROM 8.0||Good||2023-04-25||A very clear predecessor to the TI-86, and while it's missing a lot of what I like about the '-86, it's still very nice, and it has the boxy TI-81/82 shell that I like for some reason.|
|TI-Nspire (Clickpad)||TI-Nspire||School Property||S||0507||pre-A||2016031282||OS 220.127.116.118||Poor||2023-04-28||Given to me by my Freshman Algebra I teacher on Senior Day. Thought it didn't work but actually does, and just has a bad screen.|
|TI-Nspire CAS (Clickpad)||TI-Nspire||P||1009||I||2248004913||OS 18.104.22.1682||Good||2023-05-05||I flippin' hate the UI on this thing. Like holy crap. Who thought this was a good idea? Goodness forbid you wanna use the whole screen.|
|TI-89||TI-68k||I||0600||D||1360016553||Flash OS 2.09||Worn||2023-05-06||Not great condition (missing feet and has scratches) but works perfectly.|
|TI-92 Plus||TI-68k||I||0401||A||1280V04383||Flash OS 2.09||New||2023-05-13||Very useful with Mathtools and ASI. The ASISFLIB instructions show functions in neither Mathtools nor ASISFLIB, and I was wondering if anyone knew where those came from? Thanks.|
|TI-Voyage 200||TI-68k||P||1209||K||2431002642||Flash OS 3.10||New||2023-05-30||Way smaller than I thought it would be.|
|HP 28S||HP-Saturn||?||3047S03778||New||2023-06-08||Working battery cover!|
|HP 48G||HP-Saturn||?||ID81206376||ROM R||New||2023-06-17||The KEYS!!!!
But it's really slow.
|HP 19BII||HP-Other||?||D84300697||Poor||2023-07-17||Not in great condition but oh well. Still works just fine, minus an issue with getting contact on the batteries.|
|HP 19B||HP-Other||?||2916A12854||Good||2023-07-18||Though it was a BII... still mostly the same.|
|HP 49G||HP-Saturn||?||B||ID94201740||HP49-B Revision 1.19-6||Good||2023-08-08||I hate the menus
They're f*$!ing awful
I hate the UI
I think I hate this thing more than the NSpire
|TI-92||TI-68k||ViewScreen||I||1295||pre-A||V0402912||Firmware 1.4||Good||Manual(s)||2023-05-05||Very bulky. Also my hardcover doesn't want to stay on =(|
|TI-83 Plus Silver Edition||TI-Z80||S||0403||C||2094031294||Flash ROM v1.19||Worn||2023-10-28||Battery cover broken and the ( key worn completely off|
|TI-73 Explorer||TI-Z80||Original 73-style||S||0607||G||2474014590||Flash OS 1.90||New||2023-10-29||Good as new!|
|TI-73 Explorer||TI-Z80||Original 73-style||S||0306||G||2355023448||Flash OS 1.90||Fair||2023-11-02||Worse condition than the other one, but since I'd rather have that one, and can't return this one, even though the other one was supposed to be a regular -73, I have two 73Es.|
|TI-80||TI-Other||I||0698||C||39002758||ROM 4.0||New||2023-11-04||Works great, and looks great.
But we knew that.
|TI-73||TI-Z80||S||0103||C||2095000408||Flash OS 1.60||New||2023-11-24||My second try. Last one was listed as a -73 but a -73E was sent.|
|TI-84 Plus Silver Edition||TI-Z80||S||0704||A||2054022743||Flash ROM 2.21||Good||Faceplate(s)||2023-11-24||Seems like the -/Ans key is stuck
Update: Fixed! Took a lot of ""very scientific"" application of pencil graphite and quite a bit of contact bending, plus corrosion cleaning, and finally straight up bending the PCB.
|TI-86||TI-Z80||I||1197||E||07225172||OS 1.4||Good||2023-12-01||May get gutted one day to make a TI-85(6).|
