retrocomputing – Building blocks for an OS?

Bare-metal Macintosh Programming - Part 2

This second installment of my “bare-metal” Macintosh Programming effort moves past the boot block limitations of my proof-of-concept demo and introduces some foundational building blocks necessary for doing something more useful than just painting pictures on the framebuffer. Read More ›

retrocomputing – Booting a Mac Plus without Mac OS

Bare-metal Macintosh Programming - Part 1

The original compact Macintoshes (128k, 512k, and Plus) have long been a subject of my collection and study, but after acquiring a Canon Cat, I began to see the Mac in a slightly new light. The original Macintosh may be a truly unique blend of hardware and software engineering, but what if you looked at the Mac only for its hardware? Read More ›

impress.js - I'm impressed.

I thought I’d mention a new tool that my brother, Justin, recommended we use at http://www.campgroundautomation.com for a recent presentation we were putting together. We had been using Apple’s Keynote, which is certainly a slick piece of software, and miles ahead of PowerPoint, but I recently found it wanting. In attempting to update our previous corporate Keynote template, I became frustrated with the cumbersome tools and process required. I wanted to more easily adapt some of the web styles of corporate site into our presentation. Read More ›

Another great startup: WeatheRate

Hi everyone,

I just wanted to take the opportunity to highlight the startup effort of several friends of mine. Their company / service is called WeatheRate, and in their words:

We specialize in the rating of overhead transmission and distribution lines for the electricity distribution sector. Our services enable our clients to defer capital and increase operational flexibility using existing network infrastructure.

Please, head over to their Facebook page and give them a “Like.” And if you have a need for weather-related monitoring of overhead transmission and distribution lines, sign on up! ;) Read More ›

Retrocomputing Update

Since Tyler and I began our startup venture, Campground Automation Systems, 5 years ago, I may have neglected this blog, but I’ve managed to stay active in my retrocomputing/collecting efforts. I’m always on the lookout for unique, rare or otherwise interesting vintage computer items on Craigslist and eBay and I’ve managed to find some real gems over the past several years. As I strive to keep this site more current, I plan to feature some of these items in greater depth over the next several months.

Recent acquisitions to my collection include: a Commodore 8032-SK, Apple IIc, IIe, Macintosh Portable, Mac 128K, Apple 1 Replica (Replica 1), TRS-80 Model 100, and a Canon Cat. The Macintosh Portable required some restoration, and I’ve performed various upgrades on each of these. I attempt to use them all, if only for a few minutes at a time. I don’t want to see them all simply collecting dust. I’m proud of each of them, though if I were honest, I’d have to say I’m most proud of the Cat. It’s such a unique computer, quite unlike anything I’d used previously. In my next Retrocomputing post, I plan to showcase the Cat and the modifications I’ve made with the help of some of the members of the Canon Cat group. (Thanks Dwight!) Read More ›
