A Quite Obscure C128 Video Mode Hack

30 years ago, [Dave] found himself up a C128D creek without a paddle. His main monitor was on the fritz, and he needed to use his C128D in 40-column mode to run old C64 programs for development purposes. Normally this is only possible through the low quality composite out, but …read more

Make Your Commodore 16 64k, But Not A Commodore 64

The Commodore 16 was a budget home computer from the mid 1980s, the entry-level model in a wider range of machines. As its name suggests it only has 16k of memory in keeping with its budget status, and while it has the rest of the hardware necessary to run software …read more

3D-Printed Rotary Dial Keypad Is Wonderfully Useless

Right up front, let us stipulate that we are not making fun of this project. Even its maker admits that it has no practical purpose. But this 3D-printed Commodore-style rotary dial keypad fails to be practical on so many levels that it’s worth celebrating.

And indeed, celebrating deprecated technology appears …read more

The 8-Bit Guy Builds A 16-Bit Computer

One of the better retro historians out there on YouTube is the 8-Bit Guy, and after years of wanting to do something like this, it’s finally happening. The 8-Bit Guy is building his dream computer, heavily inspired by the Commodore 64.

Before we go into what this computer will do …read more

Restoring A Forgotten Dot-Matrix Printer

Dot matrix printers are the dinosaurs that won’t go extinct. They are not unlike a typewriter with the type bars behind the ink ribbon replaced by a row of metal pins controlled by solenoids, each pin being capable of printing a single pixel. At their best they could deliver a surprising level of quality, but their sound once heard is not forgotten, because it was extremely LOUD.

[Wpqrek] bought an old dot-matrix printer, a Commodore MPS 803. Sadly it didn’t live up to the dot-matrix reputation for reliability in that it didn’t work, some of its pins weren’t moving, so …read more

A Scratch-Built Forgotten Classic Of The Early PC Age

All the retrocomputer love for Commodore machines seems to fall on the C64 and Amiga, with a little sprinkling left over for the VIC-20. Those machines were truly wonderful, but what about the Commodore machine that paved their way? What about the machine that was one of the first to be gobbled up in the late 1970s by school districts eager to convert a broom closet into the new “computer lab”?

The PET 2001 might be a little hard to fall in love with given its all-in-one monitor, cassette recorder, and horrible chiclet keyboard, but some still hold a torch …read more

A Portal Port Programmed For Platforms Of The Past

If you still have a Commodore 64 and it’s gathering dust, don’t sell it to a collector on eBay just yet. There’s still some homebrew game development happening from a small group of programmers dedicated to this classic system. The latest is a Portal-like game from [Jamie Fuller] which looks like a blast.

The Commodore doesn’t have quite the same specs of a Playstation, but that’s no reason to skip playing this version. It has the same style of puzzles where the player will need to shoot portals and manipulate objects in order to get to the goals. GLaDOS even …read more

Custom Joystick For An Old Commodore Finds An Unlikely Home

Retro hardware is getting harder and harder to come by, with accessories such as joysticks and mice dropping out of the market the fastest. So if your old machine needs a new joystick, you may find yourself whipping it up yourself. While you’re at it, you might as well have some fun as [Tom Tilley] did when he built a C-64 joystick inside a replica disk drive case for his rare SX-64 luggable.

Anyone who remembers the amount of desk space the classic Commodore 1541 disk drive occupied might wonder why someone would want such an enormous base for a …read more

Little Emulators Do 8 Bits At A Time

Have you ever wondered how many, for example, Commodore 64s it would take to equal the processing power in your current PC? This site might not really answer that, but it does show that your machine can easily duplicate all the old 8-bit computers from Commodore, Sinclair, Acorn, and others. By our count, there are 86 emulators on the page, although many of those are a host machine running a particular application such as Forth or Digger.

If you are in the US, you might not recognize all the references to the KC85, this was an East German computer based …read more

Python Resurrects Dot Matrix Printing

These days a printer — especially one at home — is likely to spray ink out of nozzles. It is getting harder to find home laser printers, and earlier printer technologies such as dot matrix are almost gone from people’s homes even if you’ll still see a few printing multipart forms in some offices.

[Thomas Winningham] bought an old Commodore dot matrix printer in a fast food parking lot for $20. How hard could it be to get it working? How hard, indeed. Check out the video below to see the whole adventure. The principle behind the printer is simple …read more
