Smoke test OK. Waiting on the PLCC32 programming adapter, but in the meantime moving on to free-running tests...
We welcome retro users & hardware gurus alike! Come and join the party :)

I just tried mxplay on the Milan. I tried it years ago and it didn't work.agranlund wrote: 12 Jun 2024 23:42
mxPlay plugins, for anyone that may be interested:
https://github.com/agranlund/atarisound
(there are precompiled binaries in the bin/mxplugins folder)
midi.mxp
Plays Midi files using the bios so should work on any Atari or clone that has Midi support in bios.
opl_isa.mxp
Plays Adlib songs in vgm or vgz format on ISA cards.
So far only tested with a Resound2 OPL3 card but I have a couple of others in the pile of things-to-test whenever I get around to it.
For any Atari that has ISA slots and runs ISA_BIOS or provides a compatible _ISA cookie in some other way.
The ISA_BIOS located in Raven Github *should* work on Hades, Milan and Panther/2 too.

An mxplay plugin for Gravis Ultrasound mod playback is next in line on the list.
A couple hours solid, spread over a few evenings. My SMD soldering skills are poor, so I spent a lot of time getting an acceptable result on the buffers next to the 68150 and on the UART. There’s not a lot of fine-pitch SMD parts, fortunately.
The Falcon was Atari's last computer. It was preceded by the prototype Sparrow, which was never released. I imagine that Raven is a nod towards using birds as computer names.
Ah yes! I had totally failed to make the Falcon / bird connection somehow, despite me having been aware of and wanted a Falcon for three decades now.Atarian Computing wrote: 22 Jul 2024 08:27The Falcon was Atari's last computer.

Thank you kindly! I'm having a blast working on the computer.danboid wrote: 19 Jul 2024 02:15 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!
I double checked and it is indeed running on the Hades.mikro wrote: 08 Jul 2024 18:28 Both. :) Plugins don't know about the extended XBIOS (so they e.g. ignore if the XBIOS works in little endian) and mxPlay is so stupid that it has hardcoded hardware store/restore for Falcon registers: https://github.com/mikrosk/mxplay/blob/ ... routines.S.
