The electronics things I've found interesting. ASM80 news: WDC 65C816 support added. Hello from ASM80. Recently (a ten minutes ago, to be honest) I have added a support for WDC’s 65C816, the 6502 sequel with hybrid data width (8/16 bits). It is used in some notable computers, such as Apple ][gs, Nintendo’s SNES or SuperCPU extension for C64. Due to its dual data width, I have to added some new directives to specify index / accumulator width. You have to specify it directly with:. Index register is 8bit.

Friday, 17 February 2012. The Making of a Spectrum Loading Screen - Part.2. In the second part of this article I`ll go through the process of converting the final loading screen bitmap to a ZXSpectrum loading screen. The method we use is detailled below as a set of key stages. The first stage is to convert the .BMP image to a .SCR file. To do this download and launch BMP2SCR.exe - you can grab it here ftp:/ ftp.worldofspectrum.org/pub/sinclair/tools/pc/BMP2SCR1751.zip. All looks good with your image?

Unidad de disco virtual sobre USB para MSX. Qué es Rookie drive? Rookie drive es un proyecto personal, que consiste en crear una unidad de disco virtual USB para ordenadores MSX. El objetivo del proyecto es aprender la arquitectura del estándar MSX, programación en ensamblador de Z80, herramientas de diseño de circuitos impresos, etc. Este es un hobby apasionante, dado que fue un MSX mi primer ordenador, me apetece mucho profundizar en el que fue el primer sistema informático que tube a mi alcance. Así q...

The electronics things I've found interesting. ZX Spectrum and loaders – part three. This is a continuation of an earlier article about ZX Spectrum loaders. Hold on to your hats and get your calculators ready, we are going downhill! Continue reading ». Posted by Martin Maly. ZX Spectrum and loaders part two. I unexpectedly discovered one nice piece about loaders which I would like to share. It’s not very impressive and its magic is hidden inside, but who knows, maybe someone will find it useful. At first...

Ibán Cereijo's Blog. Skip to primary content. Skip to secondary content. A division and n-root algorithm for big numbers. In a previous post. We introduced a library for performing arithmetic operations with arbitrary precision, and in this update. We optimized the multiplication algorithm using the Fast Fourier Transform. Working with integer arithmetic; with the new ingredients, we will be able to compute some other interesting things, such as millions of decimals of Pi. Or other irrational numbers.
