Archive for Vintage Computers

Archiving Flux

For quite some time, I was buying devices to allow me to archive the over 1000 floppy disks I have acquired over the decades when collecting vintage computer systems. I know that floppy disks don’t last forever, especially if they weren’t stored properly. Heat, cold, humidity, and dirt all work against floppy disk preservation. So […]

Retrochallenge R̶C̶2̶0̶1̶8̶/̶0̶9̶ R̶C̶2̶0̶1̶9̶/̶1̶0̶ RC2020/04

Update (again) – 30 APR 2020: I’m, again, back at it. Something mysteriously fell through with the operation of the RC2019/10 Retrochallenge. The entire contest just went stale with no oversight. So… now that someone else took over the management of the Retrochallenge franchise, I thought maybe I’d give it another go. I decided to […]

Retro Christmas Wishlist: Day 16 – 20

We’re past the halfway point on this Wishlist series. I know it’s bringing back a flood of memories for me. How about you? Do you now suddenly feel the urge to hit up eBay for any of the old electronic devices you always wanted, so you can buy back your childhood? Don’t forget to go […]

Retro Christmas Wishlist: Day 11 – 15

Ten days in this series so far. Did any of the things I have posted ever show up on your former wishlists, or even better, show up as a gift during the holidays? Don’t forget to start at the beginning of this series if you haven’t done so already. Day 11: The TRS-80 Computer (1977) […]

Workshop Weekend

As a member of the Vintage Computer Federation (VCF), Mid-Atlantic Chapter, I regularly attend their scheduled Workshop Weekends, where members go to work on broken electronics (mainly, but not limited to vintage computers) in a group setting. Like a maker space, this helps our members to learn from, or mentor others, in an effort to […]

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 […]
