NORMCDF TI 84 ONLINE SERIAL
All calculators with the letter H or later as the last letter in the serial code have fewer RAM pages, causing some programs to not run correctly. Newer calculators have a RAM chip that is only 48 kB.
The chip has 128 kB, but Texas Instruments has not made an OS that uses all of it. Like the TI-83 Plus Silver Edition, it features a 15 MHz Zilog Z80 processor and 24 kB user available RAM. The TI-84 Plus Silver Edition was released in 2004 as an upgrade to the TI-83 Plus.
