There are always situations where you need a different kernel in the Commodore C64. Be it to simply test something, or because you don't want to open the computer. And so I had the idea to make such a small plug-in card myself. And for a simple Mdoul, it doesn't even need many parts.

Not everyone shares my preference for SMD. And I promised some time ago to make a version of the TriMod CBM adapter without SMD. And I would like to introduce this to you in this article. One could also say, the fasting time is over, it may be again something more...

"Oh no, not another joystick adapter" - I can already hear the prophecies of doom from the background. But this time it's not about another USB joystick adapter for the PC, but about a joystick adapter for all home computers with a D-SUB9 interface, like Atari and Commodore. And for the Commodore there is even a game which supports this adapter. Because with this adapter you can operate the gamepads of the Sony Playstation 2 on the home computers mentioned.

It's just Easter, and Lent is over. But not as far as the projects are concerned. Lent is really starting here...

As announced some time ago, this time it's about shrinking the joystick adapter on a strip grid board. Surely the strip grid board was functional and everything worked. But as far as the design is concerned, such a board will certainly not win a prize. So I shrunk the whole thing so much that all the electronics fit into a DSUB9 case.

You just want to play an old game in an emulator. Or has just built a MiSTer FPGA. Surely you have various joysticks for the good old home computers, such as Atari or Commodore, at home, but all of them have in common that a 9pin plug is used for the connection to the computer. PCs have never had such a connector. Today USB is used as interface almost continuously. In this article I would like to describe how you can easily build such an adapter on a paper tape board.

TriMod CBM Adapter

IEEE-488 floppies for the CBM world are unfortunately very rare and very expensive to get. Why not just take a cheap VC1541 and expand it with an IEEE-488 port, but without losing the serial IEC port. With the TriMod CBM adapter the floppy can do both. It can be connected e.g. to a C64 via the serial connection, or to a CBM 8032 via the IEEE-488 port.

As already mentioned in the article Replica of the IEC64 IEEE-488 board for the Commodore C64 and C128, I wanted to create a case to print out myself. This is what I want to do with this article. The corresponding STL files are available for download, so that anyone with a 3D printer can print out a suitable case for the board.

This article is about the reproduction of an old IEEE-488 interface card for the Commodore C64 and Commodore C128. This card was very handy if you had the Commodore SFD-1001 floppy, which had only one IEEE-488 connector. But also the old CBM floppy drives could be connected to a C64 or C128. Since such hardware has slowly become rare and hard to get, I have copied the board.

The XoomFloppy was already a small success and went away like the proverbial warm rolls. But now more and more people asked if they could build the whole thing with the well-known interfaces of the ZoomFloppy, i.e. IEEE-488 and Parallel Port. So I sat down again and extended the XoomFloppy. The result was the XoomFloppy Pro.

To connect an old joystick, like the Competition Pro, to a modern PC, you need an adapter. The old joysticks from home computers have an interface that today's computers don't have anymore. On the Internet you can find numerous building suggestions. Today I would like to present a very interesting adapter.

Most people who deal with Commodore hardware will also like the term "ZoomFloppy". I've been using this hardware for some time, too, but I've also been bothered for so long that the board is extremely large and unwieldy. The ZoomFloppy is also delivered as a naked board, without any case. This made me shrink the ZoomFloppy.

Commodore floppy disks with an IEEE-488 interface have unfortunately become very rare in the meantime and are sometimes sold at top prices. At that time Commodore brought the model 2031 onto the market. It was basically a 1541 with modified electronics. The differences between the two models is extremely small.  At that time, this already led some resourceful hobbyists to take a close look at the circuit diagram of the 2031 and to make a corresponding adapter.
