Forked from https://github.com/Sgw32/AmigaSID which forked from http://www.amibay.com/showthread.php?108629-Amiga-SID-player-for-Zorro-slot
Can't find the original thread on Amibay sadly, so i can't do full credits here.
- Changed most of the components to SMD, major rerouting.
- Added 100k pull down resistor and 470pF capacitor to EXT_IN of SID like pointed out at the original schematics.
- Added 245 buffer to D0-D7 databus lines.
- Changed crystal to 7050 part.
- Tied Amiga /RST to RST of SID via solderjumper (default connected)
- can be removed with a cut and be used at A4k with it's power LED connected to H1
- Added 8 jumpers (JP2-JP9) to set the memory address the SID can be accessed from the player side (needs patched player to use that address)
- Added filter caps to vcc lines of the IC's
- Changed audio connector to a more common type
- Moved filter caps closer to IC's
- Added logo
- Floating 74LS00 inputs tied to VCC
- Flipped polarity on C10 (SID_AUDIO_IN)
- Added jumper to disconnect audio out cap from output pins
- instead you now can fit a little amp board like shown Gadgets video about the original version of the card
- also added one GND and one 12V pin for powering the amp
Thanks to LIV2 and GadgetUK for the help in this project.
Use at your own risk!!!
As of now (06.01.2021) i haven't tested that, not even ordered boards!
Boards were kindly provided by SparxUK - Thanks mate!
The boards worked fine on my A500 with a Zorro2 adapter and a NanoSwinSID.
The bank of jumpers on top of the card (JP2-JP9) is used to set the memory address used by the card and the players.
Jumper setting for EE range:
| Jumper | Setting |
|---|---|
| JP2 | 1-2 (LOW) |
| JP3 | 2-3 (HIGH) |
| JP4 | 2-3 (HIGH) |
| JP5 | 2-3 (HIGH) |
| JP6 | 1-2 (LOW) |
| JP7 | 2-3 (HIGH) |
| JP8 | 2-3 (HIGH) |
| JP9 | 2-3 (HIGH) |
Here you'll find the KiCAD6 project for the board. Also there is a HTML BOM for parts placement and a jlcpcb folder with gerbers and BOM/POS for assembly (only the SMD caps/resistors, no ic's or THT parts!)
Here you'll find patched versions of players to use on the Amiga.
- Add more/better documentation
Test the Hardware, order boards- Boards were kindly provided by SparxUK
