Quote" .... Recreation Amstrad CPC464 Mini: A trip to the past with modern technology

I have recreated the iconic Amstrad CPC464, but in a fully functional mini version. This project pays tribute to the classic 8-bit computer launched in 1984, maintaining its original design but adapted to a more compact and updated format. The device retains its functionality, including an operational keyboard, color graphics and the ability to load programs, while benefiting from modern technology such as the integration of new components.

The project aims to not only emulate the look and feel of the Amstrad CPC464 but also offer an interactive experience that allows users to relive the golden age of personal computers. Perfect for retro computing enthusiasts and anyone interested in experiencing the history of computing in a fun, hands-on way.

This Amstrad CPC464 mini project uses the CPCESP emulator, an exceptional creation of Víctor Iborra ... "

Haha I'd surely want one! If only he could have used a small CRT for that case...

pelrun

Augh, now I need to make and print a 6128 mini!

I wonder how they made that awesome custom PS/2 keyboard. 

pelrun

The full assembly manual is available on the model page, including how to build the keyboard. It's a basic handwired mechanical keyboard matrix.

okay, signed up. But I still didn't figure out how they made the keycaps. Seems they are also printed - which is fair - but how do they add the characters to the finished key? 

pelrun

Yeah, the key labels are all part of the print. The trick is that they're printed using the 0.2mm nozzle, which is capable of some ridiculously fine detail, far more than people expect out of an FDM printer.

Wrong. No matter how many times this is repeated. An emulated machine is not a fully functional version. It has no expansion port, it has input, output and sound latency and it doesn't produce the hardware rasters and screen refresh. A carefully designed FPGA version could be very close to the original and even have a working expansion port, but not a ESP based emulator, no matter what you do.

pelrun

Ugh, clearly they mean "compared to a 3d model with no actual electronics". Nobody here is confused about the line between emulation and original hardware.

Hi there. I'm Eremus, coder of ESPectrum and CPCESP.

I invite you to test and read about ESPectrum and CPCESP. If you do so, you'll find that ESPectrum emulation is more precise that existing FPGA cores and whilst latency is higher, it's low enough to have convinced lots of advanced users to return his real Speccys to the self ;D

Of course, timing and video generation is EXACT to a real machine (and when I say exact, I say exact for each emulated Speccy model). It's not possible to notice ANY difference between a real Spectrum and ESPectrum (both connected to a CRT 15khz).

CPCESP, the CPC emulator, is still not as good as ESPectrum (still in alpha) but I hope will be a good replacement to a real machine. Timing and video generation is also the same as a real machine and everyone has tested it said it has no lag feeling.

Greetins ;)

I can't see how to edit own posts so:

.. everyone *which* has tested ...

I've got an ESP32 Lilygo board which has been running CPCESP https://github.com/EremusOne/CPCESP_alpha for quite some time now. I was thinking this would be the perfect project for it. Or to 'revive' some emtpy CPC464 case (but still you need to find/build a suitable keyboard)

that case looks sexy af! 
the 3d printed keycaps look amazing

Do you know Archer's Amstrad Mini it's powered by a Lilygo and CPCESP inside ?  :)

I've showcased it (with Roland's signature obtained at last Retcon in UK) at ESPectrum & CPCESP YT Channel -> https://www.youtube.com/live/di0kdZ7wY8Y?si=jpFijo2BQzU_sV2t&t=1637

Yes I recently discovered and it unlocked new desires   ;D
