From Attic Dust to Desktop Glory: Resurrecting the Amiga 600
They say you never truly forget your first love—especially if that love was a beige box with a Motorola 68000 heart.
For me, that spark was ignited during my university days with an Amiga 2000. While I haven’t been "doing Commodore" lately, fate (and a very dusty attic) had other plans. I recently acquired a massive haul of C= history:
- a highly modded C64
- an A1200
- the "Big Box" A2000
and the subject of today’s deep dive: the Amiga 600 with A601 RAM expansion/RTC module.
A Brief History: The "Junebug" That Could
When the Amiga 600 launched in 1992, it was something of an odd duck. Codenamed "Junebug," it was originally intended to be called A300 and to be a budget-friendly follower of the A500+. It famously lacked a numeric keypad—a move that ruffled the feathers of power users but made it the most portable "Wedge" Amiga ever made. Today, its compact footprint makes it a darling of the retro-community, even if it was the "accidental" successor to the beloved A500+.
The Restoration: A Labor of Love (and Solder)
Bringing an A600 back from the brink isn't just about cleaning plastic; it’s a surgical procedure.
Here is how the journey looked:
The “Battery Battle” & Logic Puzzles
The most critical task was the A601 RAM/RTC module. If you know Amigas, you know the "green death"—exploding batteries that leak acid and eat traces. After neutralizing the leak, repairing the board and replacing the SMD caps, the A601 is ticking again.
I also hit a wall with a non-responsive mouse and joystick port. After some sleuthing with a logic probe, it turned out to be a defective LS157 (a Quad 2-Input Data Selector). Replacing that chip brought the games back to life!
- The Recapping Ritual
Surface Mount Devices (SMDs) from the early 90s are notorious for leaking. I decided to future-proof this machine by replacing all standard SMDs with high-quality polymer caps. They won't leak, and they’ll likely outlive us all. - Modern Comforts
While I love the whir of a floppy, modern reliability is key. I’ve implanted a Hard Drive solution and serviced the original floppy drive, which was being erratic.
A new keyboard membrane was also installed to ensure every keystroke feels as crisp as it did in '92.
The Final Checklist
The A600 is currently 95% complete. Here is the status of the "patient"
| Task | Status | Notes |
| Case Cleaning | Done | Deep scrubbed and sanitized. |
| Logic Repair | Fixed | LS157 replaced; joystick/mouse working. |
| Keyboard Repair | Fixed | New keyboard membrane installed. |
| Recapping | Done | Full Polymer SMD swap. |
| Case Integrity | Fixed | Reconstructed those notoriously brittle clips. |
| Keycaps | Pending | Waiting for a sunny day for the Retrobright process. |
Pro Tip: If you're working on an A600, be gentle with the case clips. They are famously brittle after 30 years of heat cycles. I had to reconstruct several that had snapped off over the decades.
The Grand Strategy
As much as I’ve enjoyed the A600, this project has a higher purpose. Once the sun finishes its work on those keycaps, the A600 (and eventually the A1200) will be heading to new homes.
The goal? To cross-finance the ultimate restoration of the Amiga 2000. It’s the circle of retro-life: selling the "wedges" to build the "tower" of my college dreams.
Stay tuned for the A1200 logs!
