Re: [N8VEM: 14645] 68008 SBC



That does look like quite an interesting project.  There has always been a place in my heart for the 68k series.

However, it would be useful if he posted more detailed information online.

Would it be appropriate to extend an invitation to Simon and Project Kiwi to accomplish his objectives as part of this Google-group and The N8VEM Home Brew Computer Project?

Aside from our frustrations with the Wikipedia, this appears to be an opportunity to grow our audience/members.

I have (great) difficulty "swallowing" the reported cost for the prototype PCB -- maybe that's "all in" as regards components and possible board-iterations -- thus total-cost-to-date?

Last week we posted a link to Project Kiwi, a homebrew Motorola 68008-based microcomputer built by [Simon] that includes Ethernet, a very good display adapter, an interface for IDE hard disks, two Commodore SID chips (for stereo chiptunes), a floppy disk controller, and an already existent software library that will make it very easy to develop your own software for this wonderful computer.

After thinking about [Simon]'s Project Kiwi for a while, I've been thinking there really hasn't been a homebrew computer made that is so perfect for a proper Open Hardware release. There are more than enough peripherals in the computer to make development very fun. I've suggested doing a group buy to get Kiwi PCBs out into the wild and into the hands of other retrocomputer fanatics, but [Simon] would like a little more feedback.

Of course, this means turning to you, the wonderful Hackaday reader. Would any of you be interested in your own Kiwi microcomputer?

[Simon] tells me there are a lot of problems for turning the Kiwi microcomputer into a Open Hardware project. His prototype PCB cost €300, greatly reducing the number of people who would be interested in making their own Kiwi. Also, there are a few problems on the current PCB design (easily fixed for the next revision), and [Simon] would like to add a few features like DMA and a proper framebuffer.

Despite all those problems, I can't see a better way to learn about computer architecture the hard way (i.e. 80's microcomputers as opposed to futzing around with a Raspberry Pi). You'll also get a really wonderful computer system that will show the power of 80s-era electronics, with the very hopeful goal of spreading the gospel of retrocomputing with the venerable Saint MC68000.

If you'd like to add your two cents - if having an Open Hardware 80s microcomputer is a good idea, or some technical requests such as adding a proper 68000 CPU to future designs, leave a note in the comments or on the forum [Simon] set up on his Kiwi page.
