Raven. A homemade Atari-like computer

[DoG]

You can also buy them seperate. One 62 pin (31x2) and one 36 pin (18x2) to get a full length 16 bit ISA card slot.

mouser and digikey has them too but at a higher price than aliexpress, especially considering VAT was included in the aliexpress listing:

Thanks All. Got a 68LC060 coming too as my guinea pig and have a lot of the other parts, so hopefully get to do a bit of assembly in the next week

Quality of the Digikey Slot is better than from China ...

The isa connectors I got from Aliexpress say Wingtat. Not sure if thats bad or good. They look OK to me.

I’m now here. (As I could not find the rom ic’s for the 1mb version without needing to buy 100 pieces or so it’s going to be the 2mb rom I hope thats not an issue)
The 10k smd resistors were not on stock so still waiting on these. The big box is from mouser with all the parts and plastic packaging.
I now have an backache again from the smd parts… always the same…

Whoah!

Raven is the best Atari clone and most impressive DIY, one man computer design I've seen yet. I found out about it earlier today and felt the need to binge read this full thread. I'm tempted to build one but I may sit it out until the next revision - I've only just bought my first Atari computer a few days ago so I should have a proper go with that first. It seems like Anders has put this together in an incredibly short amount of time.

Is there a meaning behind the name, Raven?

Have you tried booting NetBSD/atari or whatever the best Linux m68k distro these days is?

I'm sure I had a few other questions but its well past my bedtime and I'm still in shock at this legendary achievement.

Anders: Could you please update the first post in this thread with a link to the Raven github please? I had to read most of the thread before I found the github link.

Thanks and congrats!

It seems NetBSD/atari would probably work but it only claims to support the PCI version of the ET4000 currently.

It would be very cool to see a Mega Drive, Amiga or Neo Geo emulator using a similar technique to your Raven ST emu although I think an Amiga emulator is probably a bit ambitious. A 68K Mac emulator is probably much more doable.

It will need some tinkering to get the peripherals in the right locations, and it'll be a bit tight on memory, but it should be doable and definitely worth a try...

Yeah we won't be running GNOME, KDE or chromium in 48 MB I realise that but most command line stuff should run fine and it might be OK to run the more lightweight window managers and GUI tools. Might even get away with running a VNC or RDP client and some emulators.

I used to run Linux on the original xbox and the Sharp Zaurus, both of which only had 64 MB RAM. The NetBSD/atari page says 4 MB RAM is the minimum required.

Many of the NetBSD port pages are a bit ... out of date. The HP300 and MVME68k ports both page during startup on 32M systems. I haven't tried a 48M config, but 64M systems don't seem to suffer in the same way.
