The EL-9300 is a graphing calculator manufactured by Sharp between 1987 and 1991. It sports an LCD screen with 10 digit precision. The EL-9300's screen is comparable to the screen of a TI-82 so is probably a 96 by 64 pixel screen. It has a proprietary link port for connecting to other calculators and an external printer/tape recorder add on.
I own a single example of this calculator which is in semi-working condition with the slide case.
This calculator is in working condition albeit is quite unstable, especially when putting new batteries into it. When I got it, it was not turning on and I saw that the backup battery had leaked and possibly corroded the board. I tried and failed to open it up but after doing so, the calculator started working while being liable to crashing. The keys are okay but lack a lot of travel, the keys are also quite small. There is a noticable delay between pressing a key in Real mode and it appearing on screen and processing which is curious. I obtained it November 20th, 2023.
