Thank you very much for this review of the last of the Casio Pocket Computer lineup. I've bought one a few years ago and I love it. It's almost impossible to find the A version or, even more difficult, a 890P. Nevertheless, it's a very fast and very complete calculator. RAM upgrade is quite easy and cheap if you have soldering skills (it's a RAM chip replacement). I've upgraded mine with 256kB of RAM which is more than comfortable with only 10 program slots per language.I also have a couple of VX-4, which are good Pocket Computers but definitely need a RAM upgrade to be usable. The RAM upgrade of the VX-4 up to 64kB is very similar to the Z-1GR : RAM chips replacement, with a solder blob to short a track in addition.
Greetings. Where can I find and buy this calculator, im located in bogotá colombia? i never seen a calculator like this before! I usually used the FX 880P.
Hello, i have one z1 calculator but i have a problem. Changing the batteries i turned on the computer without batteries, only the 2032 battery and when i put the batteries the calculator gives a battery low message. I tried to reset it but it dont work. Do you knou what i can do to restore the computer? thanks.
The display on the Casio Z-1GR is inferior to the Z-1GRA or the FX-890P (I have the FX-890P). From the HPMuseum site: "I would recommend to find a Z-1GRA or FX-890P. The contrast is much better than the Z-1 or Z-1GR. It's comparable to the high contrast LCD of the PC-E500S. The reference GRA is not written on the calculator, only on the box"

This has that great mid to late 90s Japanese tech aesthetic. I ended up buying the Sharp PC-G850V because they can be found for lot less than these.
In the film Termator Part 2 John Conner opens the blade of games with a pocket computer you can explain about it
Thank you. Didn't know about this calculator yet. Would be a great addition to my Casio "pocket 8s" and FX730P.
Yeah it is definitely the next generation on from the fx730p.

Have you thought about making your content available on LBRY?
Thanks - I hadn't heard of it TBH. i will check it out.
How can I get one similar
On EBay or Japan Yahoo! Auctions
The display seems a bit dark... ?
Yeah it’s not the best screen. There is also a contrast wheel that makes it lighter/darker.
@@CalculatorCulture Is it a fast computer, with this 16 bits ?
