https://hackaday.io/project/180536-merlin

A flexible, open platform to learn or develop 32-bit hardware or software using either a physical or FPGA solution.

The project uses a modular design to allow you to extend or move in different directions should you so wish. At it's heart is the core of a Multicomp system from Grant Searle. http://searle.x10host.com/Multicomp/index.html

IDE:

• New GCC version of EHBasic with FAT32 extensions.
  • Compiles using standard m68k toolchain.
  • Requires Merlin Newlib and Bios.
• [Easy68K] (http://www.easy68k.com/moreinfo.htm)
• GCC M68K (https://github.com/mattuna15/merlin-68k-toolchain)
  • Full working C/C++ environment (including Newlib)
  • Assembler support with Vasm

Hardware:

• FPGA: ARTY A7-35T https://store.digilentinc.com/arty-a7-artix-7-fpga-development-board/ (Required)

• TCPIP/Telnet server hardware accelerated

• GFX: Gameduino Dazzler Arduino shield https://excamera.com/sphinx/store.html#gameduino-3x-dazzler-for-arduino-39 (optional)

• Sound: OPL3 Duo https://www.tindie.com/products/cheerful/opl3-duo/ (or any OPL2/3 boards) (optional)

• RTC: https://store.digilentinc.com/pmod-rtcc-real-time-clock-calendar/ (or any mcp794xx RTC i2c) (optional)

• SD Card: https://store.digilentinc.com/pmod-microsd-microsd-card-slot/ (or any SPI sd card) (optional)

• Keyboard: https://store.digilentinc.com/pmod-ps2-keyboard-mouse-connector/ (or any PS2 interface card) (optional)

• Console is via usb-uart. Software upload via monitor over ethernet for speed.

VHDL:

CPU:

• Framework Multicomp amended to 24bit addresses

• TG68 - 68010 CPU (heavily modified)

• VGA/HDMI - Gameduino 3X Dazzler

• Basic - EHBasic 68k (Now running within GCC)

• Board - ARTY A7-35/100T

• Sound - Twin OPL3 chips (FM) Gameduino PCM

• Support for twin SPI Fram chips for external rom storahe

• PS2 keyboard.

Storage:

• FAT32 SDHC Card support with C Fat Library
• TELNET Server with support for S-Record upload via Monitor rom
• FRAM SPI non-volatile memory
