Two weeks ago I attended the Commodore Vegas Expo XII, and last week I’ve been at the Vintage Computer Festival West XI. CommVEx XII As the name describes it, it was a Commodore Expo in Las Vegas. But the format is a mix between conference and expo. It is a real expo, but with the social part of a conference. It is friendly and casual. People give talks in a very informal way. I gave a talk + live demo about the UniJoystiCle. Everything went well except that in the middle of the demo my phone’s glass broke. But that wasn’t an issue since the accelerometer kept working.

Yeaaaaaaaaaah! UniJoystiCle v0.3 was released! It includes: A beautifully designed PCB A realistic Unicycle game for the Commodore 64 A the iPhone application which can be downloaded from the App Store

This is mostly a bug-fix release, focused on improving the workflow. Download: Mac: vchar64-0.1.0.mac.dmg Win32: vchar64-0.1.0.win32.zip Source code: https://github.com/ricardoquesada/vchar64

[caption id="" align=“alignnone” width=“480”] v0.2.1 powered from a battery. Can be powered from USB as well[/caption] Changes in v0.2.1: Commodore 64 works Ok when the UniJoystiCle board is unpowered. The issue was that the 4066 chips were in an unknown state when they were unpowered. In v0.2.1 the 4066 ICs get power from the C64 Joy #2 port Smaller holes for the DC Jack making it compatible with “common” DC Jacks.

I assumed that the Commodore 1581 was failing because of a bad WD1772 IC (as documented in Part I). So I ordered a WD1772 replacement + the IC socket, I developed some basic desoldering skills, watched some desoldering videos, and also got a cheap desoldering iron from Radio Shack: So, I removed the board from the Commodore 1581 and started to desolder the IC. To my surprise the $11-buck desolder iron worked pretty well. I was able to remove all the solder from the the pins in a few minutes. The desolder iron just takes some time to reach the needed temperature, but besides that, it seems to be a great tool for occasional desoldering tasks (a hobbyist desoldering iron cost more than $250)

[caption id="" align=“alignnone” width=“400”] My Sacred Diskettes[/caption] In 1986 (or was it 1987?) I got my first computer, a Commodore 64. I started learning BASIC and during ‘87 and ‘88 I created some very simple games. Somewhere in ‘88 I started learning assembly language ( machine language to be precise), but I don’t recall coding any game using this language. If so, it must have probably been due to the fact that I lacked a good monitor. Somewhere in 1989, I switched to the Commodore 128. Whereas I continued creating games using BASIC, I also started coding some games in assembly language, profiting from the built-in C128 monitor, which was pretty decent. In 1990 I started coding intros, doing some trainers, and re-cracking some games for a local computer shop (SADOI). And I kept doing that until 1992. I stored all that sacred info (my games, intros, re-cracks, trainers) in my diskettes. At the time, my diskettes were my most valuable possession.

As a kid, I always avoided the Drean Commodore. I didn’t like them because they were not compatible with the NTSC software. As an adult, I really wanted one basically because I’m from Argentina, and the Drean was produced in Argentina. And I want to make sure that all the software that I develop works on a Drean. And in my lastest trip to Argentina I was able to get one :-) The condition of the computer is Ok, neither great nor terrible. It works, although I need to do more tests. Here are some photos:
