Hi Simon,

Nice work and good to know more 68k fans out there :)

Have you ever thought in running uClinux in Kiwi? With 4Mb RAM you are be able to run kernel 2.0.x easily (you could have the kernel image in hdd).
Then you would have a lot of tools to play with - text editors vi, ftp client/server, webserver, you name it!


I've built my own 68000 homebrew computer and currently I have latest linux kernel on it (3.8).
I've uploaded several vids to youtube showing my progress:

1) Breadboards - 640Kb SRAM - linux kernel 2.0.x:


2) Breadboards - 2Mb SRAM - linux kernel 2.4.x - added SDCard:


3) More breadboards - added ethernet:


4) Placed everything in a PCB and added a few more peripherals (also testing my old mp3 player board in this vid):
8Mb SRAM / 4Mb Flash (this is an 8MHZ 68HC000 running @ 20MHz with 0 waitstates)

Keep up this nice work!
By the way, I'm defenitivelly adding Enhanced Basic 68k to my bootloader!

Regards,
Luis

Indeed. And I have seen your homebrew computer before on YouTube. Good piece of hardware. :)

Yes, I thought about porting uClinux. Until now I thought it would be terrible slow running on the MC68008. But it's good to see you managed to get in running on your hardware already. Your achiement is quite impressing. :)
Maybe you like to support me getting a basic uClinux up and running?

Thank you! :) Yeah, EhBASIC is a masterpiece of software engeneering. I like it very much. But here the credits go to Lee Davison (he is a member here as well). You can find his original EhBASIC 68k version on his website.

Ps: I can't see your last video. :( Youtube says you are using copyrighted music which is not allowed in my country (Germany). Argh, content mafia. :evil:

I've read your blog. Can you provide code for the 3.8 kernel? It would be slightly more to do to get it up on Kiwi but it would be a start. :)

I'd better get some revision done , the last time I complied a Linux (actually it was Xenix) kernel was back in 1996!

Hi,

I wonder if I can compile it with my standard cross gcc. The last time I got pretty far with it but I stopped my attempts. Just because I wanted to use a 2.6 kernel which lacked MMU less 68k support.
Anyway I am a little bit out of time right now. I hope this will be better in December again. :)
