The small tv inside the alarm clock emits light even when it's switched off. This is because there is a layer of lumiscent coating on the tube. This "charges" when it's light and when it's dark you can see it emit a dim light. It was annoying tho, so I locked it away Now I just rotate my normal CRT TV so I can see it from my bed. It's in color!

But... Why would you buy a slow calc like the TI84+ C SE from a consumers point of view if you can get a much more powerful nspire for the same price???

That FPGA will probably not make it into the final design. That's going to be replaced by an asic I think.

Ah, so you are planning on making an asic with an onboard cpu? I can't read.

I see, thanks for the explanation. Back in the days I was sure that cartridges used some sort of ROM or chip to keep data saved until a friend lent me a copy of Super Metroid where saved data kept vanishing every few day. I was told that it was a dying battery or something, but that was only 3 years after the game came out. My Ys III: Wanderers from Ys cartridge had the same problem, but back then I thought that the fact it had 15 save slots (which was very uncommon for a SNES game) was just too much for the battery lol. The Illusion of Gaia copy I tried had similar issues, but far less worse. Years later I was shocked to see many of my NES/SNES games with their save data intact (the last time I checked, only Secret of the Stars kept losing its data). I wonder what could cause batteries to die faster or something...

At least I'm glad my calcs kept my data protected more reliably

I had this problem too with my copy of super metroid. I wound up replacing the battery.

Yes, but they had a lower resolution.

Btw is the calc on the photo a production model or a prototype? Will the consumer OS feature the same GUI?

You cannot compare the ZX spectrum to a modern calculator. The ZX spectrum did not have a dedicated graphics chip. These calculators however will have state of the art better lcd drivers.
