Floppy-only PC with only blank floppies? No problem.

Patching An Old OS for the New Altair

I’ve really been enjoying the newly built Altair I described building from scratch in my recent posts.

Cracking a 35 year old Macintosh Game

One may recall my last post on Reviving a Dead Mac Classic, wherein I repair a damaged Mac Classic. After getting it running again, I wanted to find software for it, and soon ran across the fine folks at macintoshgarden.org. This is one of the main abandonware sites on the…

Reviving a Dead Macintosh Classic

For the past few years, I’ve had an empty Macintosh Classic shell on a table behind me in my home office, the result of a Macquarium project of mine from 2000. And people love it! During video calls it always made for a good topic of conversation. But people were…
