The other dimensions that weren’t included by him were easy to find with simple calculations. He took some pictures of the machine, adding some measurements. The first challenge I faced was the case design, which was only possible with the help of Claudio Henrique Picolo, owner of an actual vintage CP500 M80C. For hardware, due to the clone dimensions, the best fit was the Raspberry PI 3, which gives me the possibility to use the “little CP500” as a very elegant development platform as well as a game machine. The SDLTRS is an open source multi-platform emulator (Windows, Linux, and Mac). The “little” CP500 would have the right scale so it would be built around an old 7″ monitor I took from a car headrest.Īs software platform for my clone I decided, after some tests, to go with SDLTRS.

Recently I decided to fix that, creating my own CP500 clone and, for the lack of space, I decided to build it using a reduced scale. So much involvement with the CP500, but I was never able to have my own. I also worked on countless projects other than the CP500, including the CP400 (CoCo clone), but that is stories for another article!

and Wii Emulator for Microsoft Windows, Linux, and Mac OS X (Intel-based). Throughout the CP500 lifespan, I worked in many different projects that improved the machine, like the 80-column video for CP/M support (which debuted as model CP500 M80) the redesign of the computer PCB, which aimed reducing its size (for the CP500 M80C) the hardware reconfiguration to double the CPU speed (for the CP500 TURBO) the capacitive keyboard and other peripherals. The emulator will determine the appropriate TRS-80 model from the disk image. All that work had only one objective, prepare me to work on the CP500 development! sdltrs is a Radio Shack TRS-80 Model I/III/4/4P emulator for Macintosh OSX. I remember to spend several scorching days reading the manual and more than often not remembering what I had just read after dozing off out of exhaustion. : 61SDLTRS - a TRS-80 Emulator for Mac OS X, Windows, and Linux. My first task when I joined the team was to read and understand “head to toe” the TRS-80 Model III technical manual. It also adds powerful development and debugging tools. The goal of Virtual T is to provide 100 hardware emulation so any existing programs will run. The article “My CP500 Prológica miniature version.”īack in 1984, after I left the Nova Eletronica magazine, and after a brief time at ITAUTEC, I was invited to be part of the development team responsible for the personal computer line at Prologica Computadores. Virtual T is a TRS-80 Model 100/102/200 emulator that runs on Windows, Linux, and Macintosh. With his authorization, the article was translated and reproduced below. The machine has even a “fake” floppies that are actually read by the drive and tell the emulator what program to load! I’ve never seen that before! Everaldo holding his “little” CP500 – He wouldn’t be able to do that with a real one!
