I’ve been up to a bunch of little projects while waiting on parts and time for the big jobs, so here is another mini-update on three of those projects.
Today was a good step forward. I finally got the case back onto the Amiga 2500, but there are still a lot of tasks left until the machine is really “ready” to be tucked away on my desk.
Now that work space is once again at a premium in my workshop, I find myself having to reassemble the diaspora of parts that were removed from my Amiga 2500 when it was dismantled to replace the 68000 socket.
Things are starting to get hectic again with real life, but there was still some time recently to work on the Amiga 2500. My objective was simple: get the machine back together into a working box again so it is no longer spread all over my workbench.
When I first got my Amiga 500, it wouldn’t boot. Suspecting something was wrong with the A501 512K memory expansion, I pulled the card, at which point it did boot. It didn’t take me long to realize that battery corrosion had killed it.
The keyboard I got with my Amiga 2500 had:
- A broken right alt key,
- A spotty (at best) return key,
- And a numpad enter key that wouldn’t stay up, but did work,
I recently flashed an eBay Gotek floppy emulator for use in my Amiga 2500 with the FlashFloppy firmware (based on the phenomenal work of HxC).
I just got my A2500’s badly corroded CPU socket replaced with the help of my buddy and his employer’s substantial rework gear.
Threw a few more hours at the A2000 today, cleaning up here and there. I popped out the 68000, cleaned up the pins, and checked the socket. The socket wipers are immaculate, not a speck of corrosion or acid on them (I checked with a magnifying glass). The pins for the socket on the underside of the board are still nice and shiny, so I’m willing to say the socket is alright.
I’ve had this Amiga 2000 for several years, but it was only recently that I put in the effort to fix it. The big problem with these machines long-term is that the Varta clock batteries explode and corrode all the traces and sockets. Mine has a leaky battery for sure, so I hope I can save it.
A couple years ago, I traded some car parts to a friend for his dad’s old Amiga A3000 and A2500. I knew that clock batteries were going to be a threat on both of those, so I nobly waited a year to take apart and desolder the battery from the A3000. That was back in 2014.
