    I prefer to run SymbOS ;)

    The rev. 2.0 comes from the factory, another advantage of ordering PCBs in China, I ordered on February 28, I had a deadline on March 9, and they sent 6, immediately emailed, attached photos.

    As for the programs, Diptrace for an amateur like me is very friendly. Intuitive schematic drawing, very easy conversion to PCB. It is also very easy to get your own element base. As a last resort, you can also import elements from the Eagle database. I generally competed for both programs with zero user knowledge and won Diptrace in terms of intuitiveness. Now I have a license for 2000 points and 6 PCB layers and I have no regrets.

    SymbOS looks pretty cool indeed. How about its applications in practice? Any text editor? WEB Browser? Java? ;-)

    The gray board is a disk drive emulator for SD cards, the board in the "edge" slot is a rombox and an additional 512 kb of RAM.

    And this is not my production, this is HXC floppy emulator. Easy to googgle ;)

    Agree, DipTrace is a very nice program ... I have a similar feeling about using this package. Only I have the impression that the program is underestimated in our country. In my opinion, the intuitiveness and ease of use of DipTrace crushes Eagle. In terms of price, Diptrace also wins.

    Respect.
    I myself used to have CPC6128 and immortal Fruity Frank. I wonder if it would be possible to make a CPC clone on modern chips, then the whole computer would be the size of a credit card. Now there are such possibilities.

    A fully populated rev. 2.0 in action. Three expansion cards plugged into the board, - 512 kb and rombox extension of the frame,
    -hard disk interface on DOM (disk on module) 128 megabytes
    -Sound card 6 channels, 2x Yamaha YM294

    It all works on a 4Mhz Z80 processor.

    To make a clone, of course it is possible, is only a matter of skill, time and money. The ZX Spectrum clone, under the name ZX Uno, has the dimensions of a Raspberry Pi.

    Wow, looks like straight from the factory :) however, the housing seems to me disproportionately modern to the historic content ;)

    Install a usb port and rj45 there, this system has the ability to run an older internet explorer with a flash player :)

    Pc Handyman, what are you talking about?

    Leonow32, you are right, the only advantage is the power supply, the board consumes almost 2 amps / 5V. Anyway, I feel sorry to close it in the housing. Maybe I will order 2 plexiglass plates with an engraving as for my other toy.

    BTW maybe there is an Ethernet module for Amstrad that could be adapted to this project? The prospect of connecting to some BBS (no longer by phone, of course, but via telnet) would be very interesting. ;)

    You can do, for example, on the ZX Spectrum there is a card called Spectranet, you can, for example, load the game from the Internet to your computer directly or use Twitter ;)

Topic summary

The discussion revolves around the creation of a clone of the Amstrad CPC 464 microcomputer, primarily for educational purposes and to save desk space. The author redesigned the original schematic using Diptrace, modifying the dedicated chip from 40007 (CPC 464) to 40010 (CPC 6128) and adding a PS/2 keyboard interface. Various technical challenges are discussed, including memory configuration, PCB design, and the integration of modern components. Participants express interest in the project, inquire about the PCB manufacturing process, and discuss potential expansions like ROM modules and floppy disk emulators. The author plans to share the design and possibly sell kits after finalizing the project.
