Did you know there was a camouflage painted SAM Coupe lurking at SAMCo's HQ in 1991/2? (Thanks to David L. for the anecdote!) Grab a limited edition Printed Circuit Board pin badge of it (plus other 8-bit computer badges) to help support what I do for SAM! https://www.samcoupe.com/quickshop.htm

How does a text adventure fit on the Dragon 32? This port of Archimedes XXI brings the Spanish classic to the system in English and Spanish, with options for 4-colour or high-res monochrome modes.

I had hoped to pop into the Centre of Computing History this weekend as they've a Dragon 32 event and say 'hello' but despite being up and down to Cambridgeshire every week at the moment I'm not able to make things coincide to be there.

But, I have designed another PCB Badge to add my growing range, this time it is of the Dragon 32!

All helps add a few pounds to the development fund for everything #retrocomputing I'm working on!

I received my "Oojamaflip" #Dragon32 adapter kit today.

It allows cartridges (minus the case) to be installed INTERNALLY to the computer. Still allowing cartridges to be plugged in externally.

It came as a kit, so I was surprised that it worked first time after my infrequent soldering skillz were applied!

With this setup I'm now running the SD interface internally so the cartridge is no longer obstructing the TV stand that I made.

Please don't judge my soldering.

a remake) https://www.marquisdegeek.com/stoneraider2 #html5 #canvas #game
