Retrochallenge R̶C̶2̶0̶1̶8̶/̶0̶9̶ RC2019/10

Update – 1 OCT 2019: Retrochallenge RC2019/10 is now underway!!! This update will summarize what I have done so far. I have already decided on the system I will use to recreate the MOBIDIC. Keep in mind that the MOBIDIC was all transistorized, and did not have any form of integrated circuit. Recreating a MOBIDIC […]

Data Transfer Between Two Commodore 64s

In a previous article, I introduced a hardware and software technique that allows for active data transfer from one Commodore 64 to another via a custom User Port cable connecting the two computers together. That article described how a modified version of the PAL assembler can invoke a direct compilation, not to disk or RAM, […]

Behind the Scenes – C64 Cross Assembling

I promised, both on this website and at VCFEast XII that I would release the details of the hardware and software involved in the “cross compiling” of Assembly language software on the Commodore 64. This article is the fulfillment of that promise. But first, let me define once again what “cross compiling” means in this […]

Retrochallenge 10/2017

That time of year again… It’s Retrochallenge time! Retrochallenge is where you challenge yourself to use vintage computers for a personal project for a month. This time, it’s for the month of October 2017. For my Retrochallenge, I will be rewriting an old Christmas graphic and sound demo I wrote on a real VIC-20 computer […]

Cross Assembling on a Commodore 64

These days, the term “cross assembling” means that you use one computing environment to develop applications for different computing environment, like using Windows to make games for a Nintendo, or writing 6502 assembler on a system with an x86 CPU. For the lack of a better term, I’m using cross compiling to describe a means […]

3D Graphics – Amiga Style!

A long, long time ago, in an era so far away, an Amiga was all that I had… My early computing days were Commodore centric. I had a VIC-20 for my first computer while in high school. Then in my first years in the military, I bought a Commodore 64. A few years later, I […]

VCF East 10.0

Time to blow off the dust settling on this stagnant website and post a new article documenting my experience at the Vintage Computer Fest East 10.0 (VCFEast) event. The event is over, and I’m now recuperating from the tempest of activity which filled the weekend of April 18 and 19, 2015. I’ll start with the […]

Blog Response to the YDKF Podcast Episode 157

I just got done listening to Rob “Flack” O’Hara’s latest “You Don’t Know Flack” (YDKF) episode #157 called, “Printer Extravaganza.” I thought I would try something different and post a full response on my own blog. This post may be light on some details because it is in response to information specifically mentioned in YDKF […]

Updated Jan 20, 2015: My RetroChallenge Entry for January 2015

Twice a year, I enter the contest known as RetroChallenge. It is an informal challenge for all participants to do something with retro computers for one month. The next “Winter Warmup” challenge starts New Year’s Day, 2015. Although there is a contest aspect to the event, it’s really rather ungoverned or scrutinized as a contest. […]
