A little more than two weeks later, the prototype board for the audio outputs of the new Drumulator is practically finished.

It has been a while since I last posted about the Drumulator.

What do you mean, a clone of Akai's S56usb USB card?

I would simply say: with as few nagging concerns as possible.

The MSX cartridge saga continues...

From time to time, I've mentioned the little computer designed by Frederick John Milens.

Despite this intense heat, I managed to make some progress on my developments.

Today's reflection: US customs duties.

In the series "other distracting activities during the heatwave," I looked into the very simple development by a "local guy"—that is, a Frenchman—who created a small computer based on the 6502 processor, with the particularity of being able to connect to…

Between two "high-tech" developments, back to pure 80s style.

Implementing an FPGA isn't very complicated in itself.

While waiting to receive the printed circuit board for the MSX cartridge, I started working on making a compatible USB card for the AKAI S5000/S6000 samplers.

A few years ago, I developed a regulated power supply with three outputs: +5V, +12V, and -12V, primarily intended to replace the one found in the Prophet VS.

Over the past few days, I've returned to implementing the Drumulator in an FPGA.

So this time I'm not really making progress in terms of building this MSX cartridge, but I'm tackling all the programming aspects of the future equipped cartridge, which therefore includes an Efinix Trion FPGA.

On this cartridge, I'm at the stage of trying to create the PCB.

Might as well say it right away: it works.

Some months ago now, I decided to create a cartridge for MSX computers.

I have been experimenting with Efinix's development tools for several weeks now.

A few months ago, I presented Frederick John Milens' initiative to build a small computer in the purest style of the 80s, closely resembling the Commodore 64. https://www.codycomputer.org/ Since then, the new version of the Commodore 64, the Commodore 64…

I really appreciate the support of AI.

Until now, I've been using SDCC without fully mastering its compilation and linking process.

After a few weeks of practicing with AI to help me with coding, whether in VHDL or for developing Windows utilities, I must say that its contribution is very positive.

And yes, the Drumulator system is finally working in the Trion FPGA.

Currently, I am working on two major projects.

A few months ago, I tried to code a ZILOG CTC in VHDL.
