Island-style keycaps for the Commodore 64

At the end of January, I pre-ordered my first 3D printer, an Anycubic Kobra X, and used the waiting time to look for an open-source (or free for non-commercial use) CAD application, as well as ordering a few spools of filament. I started with two spools of PLA+, two of PETG and one of TPU. [ ]

I bought this computer from the son of a retired dealer and repairman at my usual market in November 2011.

Atari 7800 (1986)

This console, with a few games, cost me 50,000 Lire in 1998 (before the Euro), which is about 36€ or 41$ today.

I was familiar with a couple of variants of this console: the original Japanese PC Engine from 1987 and the American version from 1989 called TurboGrafx-16.

I received the two computers as a gift from Enrico S. in 2011. The inspiration for this article came from a message I received from the contact form: Hi, I don t see the various Amstrad CPC464, 664 and 6128. I only found a reference in a Sinclair post. Am I wrong? So I pulled the [ ]
