Look what the postman dragged in :D


@Steve & @luciodra, I'll pack them up for you and send them this week. For others, there's still 2 available.

So that was the main issue it seems. A dodgy 68150 or at least one that does not like 48..
Video is working perfecty at all resolution. No strange crashes.
Was wanting to try your new roms and cpld however then there was a big bang. Almost like a gunshot.
I thought it was the Raven however it seems the power supply in my PC has exploded.
But the Raven is OK. :)

Wow! Scary stuff, hope the rest of the components in your PC survived.
Interesting with that 68150, was the replacement one also a 33mhz version?

Both were 33mhz versions. So people who are building a Raven get a 40mhz! 33 could work but maybe not...
Do you want the dodgy one maybe?

Plugged in my yamaha isa sound card which looks simalor to your red one. Runned the isa program (recognises an OPL3) and indeed I know hear OPL soundssss from the speakers. So that works great. OPL3 is indeed really cool..

(Indeed I hope my PC is OK there seems to have been a recall on the blown PSU describing this issue lets see if they send a new one and the rest of the hardware still works.)

In preparation for Ultrasound MOD plugins I decided to clean up and refactor my existing plugins codebase.

- mxPlay and Jam versions now share common codebase, except for only the player specific part.
This makes everything a lot neater compared to the old copy/pasted stuff in two different places.
As a consequence, the Jam version of the midi plugins should now work properly as they no longer use outdated code.

- OPL plugin is now using a proper delay function instead of delaying by abusing the ISA bus with invalid reads like the original DOS code did

- ISA_BIOS is no longer a hard requirement and if not available the plugins will attempt to best-guess bus details based on machine type (hades, milan, panther, raven)

- Plugins will try to autodetect port settings of certain cards if ISA_BIOS is installed. Fallback to 0x330 for MIDI and 0x388 for OPL.

Sourcecode moved to a new player-agnostic plugins folder:
https://github.com/agranlund/atarisound ... rc/plugins

Binaries are located in the same folder structure as before:
https://github.com/agranlund/atarisound ... /mxplugins
https://github.com/agranlund/atarisound ... jamplugins


Now time to transition my GUS testing code to plugin :)

Formats: FastTrackerII (.XM) + "generic" modules (.MOD)
Future: ScreamTracker (.S3M)

Hardware: UltraSound PnP (AMD chip)
Future: Ultrasound / PicoGUS (GF1 chip)
Future-future: Soundblaster AWE32/64

Nice!! That's awesome :)

The 33mhz one I tested briefly appeared to work, but that test was far from rigorous.
I guess it's a bit of a gamble with those slower rated versions. If you are willing to part with the dodgy one I'd be happy to take it off your hands for testing at different bus speeds.

Looking forward, I'd like to verify and fix anything related to running at different clocks. Especially 64/32 for those slower 68150's.
But you know, don't hold your breath waiting for it :)
I second @Oldskool and suggest the 40mhz version as less of a gamble than the 33mhz ones.

Regarding the BOM.
I notice the buttons are red color, the plcc sockets are brown, and the jumpers are just terrible (they are hard to grab).

The first part number is the one in the current bom and ones under may be more suitable.
Unless anyone can see some obvious mistake then I think I'll update the bom on github with one of the better options?

The jumpers lack the usual groove and are really quite hard to get a grip on if you want to remove them.
I ended up using better model spares I had laying around but if anyone has a part number for a good one I'd be happy to update the bom.

Oh, and @Oldskool , where did you get those black Simm connectors from and do you have a part number for them? :)

Black simm sockets:

I don’t think you can still buy them new new..

Raven making noise :)



Many thanks for mxPlay @mikro, not having to deal with GUI and just focus on playback code is a blessing.
