MOnSter 6502

Posted by jpluimers on 2016/05/16

This is so impressive: MOnSter 6502 basically a 6502 on a PC board running at 100s of kHz.

On Nintendo’s choice of the 6502 for the Famicom, later to be the NES, and the BCD patent.

Posted by jpluimers on 2016/04/10

Very cool This week, a look at Nintendo’s choice of the 6502 for the Famicom, later to be the NES.

It skims on the BCD patent, which they covered before in more depth.

Apple@40: happy birthday!

Posted by jpluimers on 2016/04/01

Apple Inc. just turned 40 today. Happy birthday!

Based on Mac@30, here is my educated guess for Apple@40.

(Boy what were they thinking when establishing Apple Computer Inc. on April 1st 1976)

Easy 6502 by skilldrick: an ebook tutorial to learn 6502 assembly with embedded simulator

Posted by jpluimers on 2015/08/04

A while ago, Alan Cox write a G+ post pointing me to Easy 6502 by skilldrick. The last couple of weeks I finally found time to play with it:

It is a tutorial ebook by Nick Morgan with examples and a play ground based on the adapted JavaScript 6502 assembler and simulator right integrated into a github.io site.

From the perspective of learning assembly language to get a grasp of thinking at the lowest computer abstraction, it is an ideal tutorial: the 6502 is a very simple 8-bit processor with only 3 registers. These restrictions make programming fun.

These are the topics covered:

This is what Alan thinks about it:

… some of the other 6502 tutorials

This one is really really neat – bit more basic than the bits I need to brush up on but really nicely done.

mos6502: “This is currently the oldest publicly available piece of source written by Bill Gates.”

Posted by jpluimers on 2015/04/09

mos6502 wrote a really nice post on G+ with this quote:

“This is currently the oldest publicly available piece of source written by Bill Gates.”

A must read if you ever used Microsoft BASIC on a 6502 machine.

Lots of link to various sources of the Microsoft BASIC (it was developed on a PDP-10 that could even run the outputed 6502 assembly!)

Keyboards, logo keys CUA and a some more history…

Posted by jpluimers on 2015/04/06

My response to the comments in Cut and Paste Files & Folders in Mac OS X got a bit took long. So here is it in an article:

Indeed. CUA. The days (:
I’ll write more about CUA in the future (there is some CUA site:wiert.me stuff from the past) as it defines a lot of modern UI and user experience.

In fact the history of Ctrl-C and Command-C goes back until before System 1 (the OS for the first Macintosh) which indeed had the Open Apple Key shortcuts, but didn’t introduce them.

The Command Key was introduced in the Apple III and became more popular in the Apple //e and //c (I own both) where AppleWorks was already using these shortcuts in 1986.

It is funny to notice that Apple keyboards lost their logo keys but Windows keyboards gained them.

Some Apple keyboard pr0n can be found on Wikipedia.

For the 6502, 65c02 and 65816 freaks out there: WDC have made their Programming the 65816 Including the 6502, 65C02 and 65802 available for free again

Posted by jpluimers on 2014/12/24

Cool:

Shared publicly

For the 6502, 65c02 and 65816 freaks out there: WDC, who still produce the chips, have made their Programming the 65816 Including the 6502, 65C02 and 65802 available for free again (see link below). It’s the standard reference for the new version of these CPUs. Yes, this will be on the test. Ping +Alan Cox HT to BDD on 6502.org

Soldering your own 6502 together: Ben Hack creating an Apple I, others doing NINA65, Loom 6502, etc.

Posted by jpluimers on 2014/11/17

Some great links posted last week by mos6502 about soldering your own 6502 based computer.

The videos are of Ben Heck building an Apple I replica. But others did similar builing of NINA65, Loom 6502 and others.

I wish I had soldering skills like that, but I’m more of a programmer (that started on a 6502).

Great viewing those links and videos.
