Inspired by Fuzion's comments about waiting for Amber to support Proconn, I took another look at getting a z80 cpu running.

 

And it appears to be have been mildly successful. Its early stages, but I can see stuff happening in the debugger that makes sense.

 

I was hoping to keep it quiet as a surprise but I figure its best to get it out in the open and appeal for resources. Anything and everything Proconn related will be gratefully received.

 

If things go as well as I hope the next release of Amber should see Proconn in its initial stages, and a fair few fixes for MPU3, MPU4 and M1.

 

The C++ conversions are coming along steadily too. The hope is that by Christmas this year, Amber will support the following techs, all in C++ dll's, ready to write the Project Amber 2 fully 3D front end.

 

MPU3, MPU4, System 83, System 85, Scorpion 1, Scorpion 2, M1, Castle Rev 1E, Castle Rev 2A (subject to reosurces), spACE, SRu, Proconn, Universal.

The z80, and the z80CTC (timer), is now in and running. Its looking more like its doing what it should now.

 

Next is to write the PIO code and start hooking up peripherals.

Excellent stuff mate,isn't z80 what electrocoin used as well?

 

It was on my Bar X Casino and I'm pretty sure it would also cover their earlier, and hi-tech machines. A pair of Z80s. Funny board the old Electrocoin one, it was more like an arcade machine board with a pair of Jamma type connectors on it - presumably the same (or very similar) to what Electrocoin used in their video game cabinets?

 

If so I'd assume it would be a piece of cake to emulate (even in something like MAME) although I wouldn't have a clue what I was doing myself

Oh this is awesome news Guitar it really is. Many thanks for working on this, Project coin in mfme is not fully usable, dip switches to change stake etc don't work, messed up DMD erc. Hopefully you can get this cracked and we can see some of the Projects in all their glory. All the best.

Does anyone know what the differences are between PC90, PC92 and Proconn plus?

 

CW has attached an AY8910 chip for Proconn, whereas the PC92 board I have in my hand uses a YM2149F chip for synth sound. The DIPs are probably attached to the IO port of the sound chip. I think a better distinction needs to be made between the 3 boards to ensure proper game compatibility.

 

If anyone can confirm/deny?

I know of a special rare machine but I need to find a local rom dumper for it
