Title PedroM 0.81 (GNU GPL)
Description PedroM is a complete new Operating System (OS) for Ti-68k calculators. It does not use any code from Texas Instruments OS nor Advanced Math Software (AMS). There is plenty of Flash memory available (228 Kb of RAM and 1900 Kb of Archive) and there is no Computer Algebra System (CAS). PedroM has a modified version of the PreOS core as built-in, so you do not need to install a kernel extender. It uses the latest version of PreOS. So you can natively run nostub programs, kernel programs (version 2, 3, 4 & 5), PPG and pack archives. By the way, it works on 92+/89 Hw1/2 and V200/89 Titanium (without usb support). It should be very stable, but you should test it on an emulator before replacing original TI OS to avoid misunderstanding of what PedroM does.

Note! This review was written for a previous version of this file!

PedroM is a wonderful piece of software. It's a marvel, and is definitely the first independent OS for a TI calculator. It does have basic arithmetic built in (editors fix me if I'm wrong; I think it has simple division, multiplication, addition, and subtraction)

The UNIX like interpreter might intimidate users who have never seen UNIX, but its fairly simple to understand, and has a help command. Also, the lack of BASIC support might seem bad, but I think it is good, mainly because it encourages people who know BASIC to learn ASM, takes less space on calculator, and doesn't fill up ticalc's archives with useless BASIC programs (I know very few that are actually good, and I used two program in it). Overall I'd give it a 9 out of ten; It is wonderful, is an independent OS, but it lacks the CAS, the only reason I took one point off.
