The Mega65 is a for the Commodore 64 (C64) and the Commodore 65 (C65) Compatible 8-bit home computer based on a total of three Field Programmable Gate Arrays (FPGA) for real retro fans and can be pre-ordered now. The open source project has its price.

A modern Commodore 64 and 65 with FPGA

With the Mega65, the two classic 8-bit home computers Commodore 64 and Commodore 65, which were particularly popular with gamers, “arrived in the 21st century” with the help of several FPGA chips, such as the one from the “Mega Museum of Electronic Games & Art eV “initiated project on the website and in the shop of the Mega65.

    The basis of the Mega65 is a Xilinx Artix A7 200T FPGA for the circuit, which is supported by an additional MAX 10 FPGA. An 8-bit CPU clocking at 40 MHz, 384 KB Fast RAM and 8 MB of serial RAM are also on board, as well as a 100 Mbit / s fast LAN connection and two SDHC card slots. The Mega65 also contains a licensed C65 ROM and a Cherry MX-based keyboard with a metal frame, as well as an internal 3.5-inch floppy disk drive.

    FPGA solution offers many possibilities

    In addition to the C64 and C65, the Amiga and Atari platforms will also be supported and other home computers will be taken into account.

    The Sinclair ZX Spectrum has also risen again

    In addition to the Mega65, there are other exciting retro projects in the form of rebuilds, especially for retro fans of unforgettable classics from the golden era of home computers.

    One of those projects is the Sinclair ZX Spectrum Next, a replica of the Sinclair ZX Spectrum, the successor to the Sinclair ZX81 by legendary British developer Sir Clive Sinclair.

    The editorial team thanks community member “Eratosthenes” for pointing this out to the project.

    Update 10/3/2021 1:24 p.m.

    In the meantime, some retro experts from the ComputerBase forum have excelled in the comments on this news item. Above all, community member “MR2”, who is very well informed about the project, stood out in particular and provided a lot more information about the Mega65.

    In addition, the reader pointed to the official one Mega65 YouTube channel that offers a variety of interesting videos about FPGA-based home computers.

    Among other things, the Boot time between a Mega65 and the C64 replica TheC64 (test), which the editors have already hosted.

    In addition, the community member refers to the German-language user manual of the retro system, which is currently being created with the help of the community.

    As a community project, the manual is currently being translated into German. So if you want to help, please contact forum 64 (…)
