Music 500(0) schematic

Post by flynnjs » Sat Apr 02, 2011 10:54 am

Does anyone have one? I've read the description of how it works and it doesn't seems that complicated and was wondering about building an FPGA based clone.

I've not had any contact about schematics.

However, I've had a PM from a friendly regular on here who is willing to dig out a real unit. I'll buzz it out and recreate a schemaitc from that and post it up in due course.

It's not a schematic, but if you're going to reverse engineer anyway this might help.

B.t.w. I would love to see this in one of the emulators......

From the motherboard scans looks like pretty much all LSTTL, apart from what I asume to be a couple or RAMS (big AMD chips), and the 3 chips in the bottom right corner.

Should be ripe for implementation in a CPLD / FPGA.

Cheers.

Indeed. The 2 big AMDs are ram chips and as far as I can tell the 3 on the right bottom are the DA converter and 2 opamps.

The rest seem to be fairly basic logic chips.

There's some technical info here on the 5000 which might help a little.

EDIT : D'oh! Should really read all the posts #-o

Apologies for resurrecting an ancient thread.

A few years have passed, and I'm wondering if the schematic for either the Music 500 or Music 5000 has turned up anywhere?

Like flynnjs, I think this would make a nice FPGA project.

This should help . . . Posted before in my Various Documents. Not sure if it's all there, though.

Excellent, and it looks fairly complete to me.

And it's great we also have Chris Jordan on the forum.

I can see another little project coming up.... I need more vacation time :lol:

It was, probably, Chris that supplied the schematic when we were doing the Electron version of the Music 500. I still have both the hardware and soft/firmware for it. On my list of jobs-to-do :wink:

A lot of similarities in that to Sega PCM audio circuits on things like Hang On and Space Harrier.
