Christmas present: a 20 year old stylus operated CAS calculator; those days "500KB RAM" and "5.4 MB Flash Memory" were supposed to sway a punter's decision. At least it had a snap-on hard cover.

Not printed on the box: 200MHz SuperH 3 32bit CPU, 160x240 pixel b/w display (66% more than a Gameboy!). It has a Basic interpreter, but who has the patience to program with a stylus?

Geometry mode feals a bit like 1990s CAD systems. All in all a fun toy!

Anyone here got a CASIO CP400 or CP400+E (ClassPad II)? Or CG500 too, since that’s just the same calculator on a different enclosure.

It’d be really helpful if y’all could submit your calculators Serial Numbers to my.calcs.quest!
As well as do the Diagnostic1 key combo to figure out your ABS_Date (maybe add at ‘comments’?)

Specially if it was bought late 2022 or later (but older models, submit too!): Apparently there’s a new revision for the ClassPad (possibly for the cg500 too? haven’t seen that) that breaks compatibility with OSes older than 2.01.7, and hollyhock runs on 2.01.2. We’re trying to figure out what changes and how the SN works at Hollyhock-2 discord.
We know that affected calculators have an ABS_Date of 2022, while afaik all previous ones had an ABS_Date of 2012.

I have a CG500 bought in mid-2022, but it (thankfully) has the 2012 ABS_Date.

Experts noticed signs of intrusion on October 11, when the ClassPad database crashed within the corporate development environment.
