JiffyDOS and SD2IEC Command Quick Reference Card

Here’s a cheat sheet I printed up because I tend to forget less often used commands for the JiffyDOS DOS wedge. It also has some commands for the SD2IEC for changing and saving the default drive number.

4×6″ Formatted PDF: JiffyDOS_Quick_Reference_Card.pdf

Text file: JiffyDOS Commands.txt Also, the text is wrapped so that the first list of function keys displays nicely on my 1541 Ultimate (and Ultimate 64) file viewer, so this text file can be dropped in the root of the SD card for quick access in the menu.

I printed this out and laminated it. Here are some pics.

My Ultimate 64 and a Commodore SX-64

I finally got my new C64C case from Pixelwizard Retro Shop. If you don’t know about these: these are new cases made from original Commodore C64C molds. They are a perfect fit for real hardware because they are from the real molds. And they make a great option for pairing with a new Ultimate 64. And if you don’t know about that: the U64 is a modern FPGA implementation of the C64 (and then some), with network, USB storage, and HDMI output.

I chose the SX-64 style case. I happened to come across an Aldi C64 keyboard, actually pretty rare in the USA. I like this keyboard because it is nearly white, making a good style match to the original SX-64 colors.

So here are some pics!

Getting Stereo sound from mono SID tunes on my Ultimate 64 (Retro Ruminations Video)

I recently acquired an Ultimate 64 Elite board. After I configured it for stereo sound using one of the internal emulated SIDs, and a real socketed SID, I posted a video to facebook showing it off. I got a few requests for screen shots of the settings, and thought a full video would be fun, demonstrating the actual sound as well as the settings.

Also, I have been planning to post short “ruminations” on my thoughts about Commodore and other vintage computing/gaming hardware. I figured this would be a good first video. Please use the YouTube subscribe button if you’d like to see more… and like the video, too!

SID file for this music: Bombo.sid (tune #2) (I prefer having it play back at NTSC speed.)
