I've been working on a design of a 68000 based computer.

It's heavily based on the 68008 Kiwi computer by Simon Ferber. https://www.ist-schlau.de/
Close enough that we should be able to share source code between the projects.

It's a 68000 computer clocked at 10Mhz.
Two SID chips and a V9990 video chip.
Keyboard and mouse ports along with Serial, Parallel, USB and more.

The Kiwi is a great computer (and i have one) but ii have wanted to build a full 68000 computer for a long time, still very much a work in progress but getting there.

Quick edit: Ddriag is welsh for dragon

Welcome! Good looking board - I see there's a SIMM socket for your RAM. What are the four zig-zag sockets for?

Thanks

The zig zag sockets are for the video ram.512K. For the main memory, some ram reserved for the ROM and IO but should have a massive 15.5M of ram available :)

Very nice work. I see you already have boards made, but I do offer a SRAM module of 4Mx8, 5V, 10ns. See the front page of my website. Link below.
