8086 disassembler using 64 bit assembly language

8086 disassembly application. Project done during computer architecture course. Project is done using nasm(yasm) 64 bit assembly and some c functions to handle input/output. I have chosen such technologies because I was curious about few topics: Learning about asm 64 bit programming Compiling assembly executable for windows 64 platform. During the comp architecture course we were doing assembly programming for a ms dos using dosbox. I was interested in making some executable code on a windows 64 platform. Linking assembly code to some higher lever programming language library. During the…

Program to find GCD of two polynomials

The objective is to write a program that finds greatest¬†common divisor of two polynomials g(x) and h(x). The task does not define what form we get those two polynomials, so let's say we will get them in a form of a String, something like that: $latex ``2x^3+5x^2+8x+3``$ Let's start splitting our problem into chunks and gather some information about the steps we would need to implement. First, what is the greatest common divisor? In math, GCD of two or more integers, which are not all zero, is the largest positive…

Removing supervisor password (SVP) on ThinkPad T42

Recently received two ThinkPad T42 laptops ( some company decided to upgrade its IT and were giving away them almost for free ). After turning them on got an 271 error and later was prompted to enter password. It seems battery was dead on both of those laptops and when its dead, real time¬†clock goes bananas and you are asked for supervisor password to set the clock again ( if supervisor password was set ). Offcourse nobody knew anything about what password it was. So had to figure it out…

ZX Spectrim 128 +3 composite video output and drive belt replacement

Did some work on ZX Spectrum 128 +3 I have. One thing was I wanted to make it work with small "TFT Color monitor" (for a car rear view). This monitor has a composite video input. First I tried using CSYNK and GND signals for a composite video input. You get the video but it was terrible quality. It seems that "The 128 ZX Spectrums including the +3 (and +2A, +2B) have audio sound modulated onto the video, which reduces the clarity of the composite signal that is available at…

The Shallows: What the Internet Is Doing to Our Brains

Recently have finished this book. From the times of Plato and Aristotle our brain and way of thinking is changing and adapting to our way of living. Every tool we use becomes a part of us, but also we become a part of a tool we use. Clock, written word, computers, world wide web. Everything we use changes us, changes how we think, changes how we remember things. Its a good read that raises a lot of interesting topics.
