Old School Audio Preamp Project

Old School Audio Preamp Project

Finished wiring up this behemoth of a project yesterday and wanted to share some shots of the final product. It’s based on an Altec 1567a mixer but with some improvements. I added some FET buffered direct outputs on each channel, phase invert switches, output attenuation, and grid stoppers on the high impedance inputs.

Another kitset 6502

Another kitset 6502

Over the last few years I have designed a kit set computer called “Alius 6502”

The base design is a 1Mhz system, but I had had it run stable at 4Mhz.

Some people will see that it has used the KIM-1 as inspiration, a hex keypad and a seven segment display.

The design was to be aligned with what would have been available in 1979. The Kailh keys are modern, and the SDcard interface is modern.

32k of RAM, 16k of ROM, FAT32 support.

This is aimed at students, I have had a group of teenagers make the kit over two days.

The whole project is open source, hardware, software and documentation. Feel free to help me make it better.
