Welcome to alxlab!

This is the home of alxlab, creator of affordable retro tech solutions.

Currently I'm concentrating mainly on projects revolving around old Macintosh computers, but I also like to do projects involving the Sega Saturn.

Macintosh Projects

Macintosh DB15 to VGA

An adapter to allow a VGA monitor to be connected to a Macintosh.
Apple DOS Compatibility Card PDS Extender

A Macintosh PDS DOS Compatibility card extender that allows you to use the DOS card in computer like the Quadra 700 and Quadra 950.
Macintosh Portable Battery Adapter

PCB and 3D printable case designs to allow readily available 6V rectangular lead-acid batteries with spade terminals to be used with a Macintosh Portable.
Macintosh Portable 50-pin Hard Drive Adapter

An adapter that converts the Macintosh Portable 34-pin SCSI to 50-pin SCSI so 50-pin SCSI devices can be used as the hard drive.

Design Reference Library

This repository contains reference designs of PCB to be used as a base for other projects.
Bourns 4120R-601-250/201

Project to replace the Bourns 4120R-601-250/201 filters on Macintosh SE and SE/30. Can also be used to replace other Bourns 601 Series filters.
68040 Heatsink Clip

This is a 3D model for a 68040 heatsink clip. This will allow you to attach a 45mm x 45mm x 10mm heatsink to a 68040 processor to give better cooling.
CR2032 to 1/2AA

This adapter will snap into a 1/2AA or 14250 battery holder and allow you to use much cheaper and safer (old 1/2AA can leak) CR2032 batteries.
