Apple 27” Thunderbolt Display

My Apple 27” Thunderbolt Display was flickering on and off intermittently (running on my M1 MacBook Air via a Apple USB C/Thunderbolt Adapter). Turns out it was the integrated Thunderbolt cable – I’ve connected it using a seperate cable and it now works perfectly (the display has a separate Thunderbolt port you can use).

Eventually I may try to replace the cable properly but it’s a fairly involved job… (thanks Apple!).

Dusting off my Apple IIc

Snow White 🙂

I have a pair of Apple IIc units (with matching power bricks), an Apple IIc monitor (complete with stand), an external Apple IIc floppy drive and an Apple IIc mouse (in original box no less).

In some brief testing, everything apart from one of the Apple IIc units worked perfectly (including both power bricks). This includes all of the 5 1/4 inch floppy disks I tried!

As you can see from the following photographs, the monitor is still crisp and bright. Not bad for around 38 years old!

With any luck, repairing the other Apple IIc unit shouldn’t be too hard. Everything is intact and present and there are no signs of damage.

Turns out my working Apple IIc is an ”original” ROM version.

System Utilities Version 1.0 (1984!).
Cool keys (that need more cleaning)

A trip down memory lane – the Commodore 64

The first computer we had when I was growing up was a Commodore 64. We had it in the late 80s/early 90s – when it was old but not yet retro cool. It was my introduction to computing and I have fond memories. We had a tape drive, joysticks and the paddle/wheel controllers. Some of our favourite games were Wizard of Wor, Lemans (top down car racing game with the paddles), The Last Ninja and Impossible Mission. A few years later it was relegated to storage as a Window 95 486 PC and a Macintosh IIci took it’s place (we didn’t miss the tape drive and it’s propensity to find errors 30+ minutes into loading a game).

Fast forward a few decades and, thanks to John, I am now the proud owner of a Commodore 64C. John also hooked me up with a modernised power supply, joystick, S-video cable and a 1MB (!) cartridge full of programs. I’m using an S-video to VGA adapter to drive an old 17 inch LCD. Graphics isn’t perfect – I’ll be trying another old LCD soon.

Commodore 64C goodness

Loading up the 1MB cartridge and there is Wizard of Wor!

An instant hit with my youngest two!

There is currently a battle going on to see who can get the highest score…

Apple Newton MessagePad (OMP) Repairs

In an effort to scale back my collection, I have been going through my Apple Newtons. I have 4 OMPs (Original MessagePads) – two are dead completely and two are exhibiting the glitches expected from bad capacitors.

The OMP stash (battery leakage occurred prior to me acquiring them)

After watching the following excellent YouTube video I decided to tackle the recapping myself.

Stay tuned for progress updates!

Pebble Development in 2020

After a fair amount of trial and error I now have the Pebble SDK working on my Mac (macOS 10.15.4 Catalina). I was working from the guide here. I can now create, build and deploy programs and watch faces to my Pebble watch.

Firstly I had problems with the virtualenv command:

cd ~/pebble-dev/pebble-sdk-4.3-mac
virtualenv --no-site-packages .env
source .env/bin/activate
CFLAGS="" pip install -r requirements.txt
deactivate

It turns out the –no-site-packages flag is not required and should be omitted (see here for details).

I then had issues with no SDK being installed (and the scripts trying in vain to locate the SDK on the Internet). After trying:

pebble new-project testing

I was greeted with:

No SDK installed; installing the latest one...

Consulting Google yielded:

The key part of the reddit post is path to the SDK. I used the following to successfully install the SDK:

pebble sdk install https://github.com/aveao/PebbleArchive/raw/master/SDKCores/sdk-core-4.3.tar.bz2

The last fix was disabling the analytics tracking by creating a NO_TRACKING file in the SDK directory.
