I'm basing my PCB on your research :D
I had not doubts.Nowadays most of people take advantage of public/shared info and use it to make profit, I kindly ask you to not do the same with mine.Thanks.
No, it's just a hobby. Have no intent of selling. I plan on donating the extra PCBs. Just trying to help.

I started on PCB today. It's still rough. Plan to do clean-up tomorrow.

I'm adding jumpers to make it easy to test with or without pull-up resistors...

Last time i said something similar, i got the answer : "Then why did you have put all your formats documentation on your website and the software in open source ?" :|
Yes, very smart answer from a very smart guy :lol:
These people must understand that the fact that we share our information does not give them the right to use it to make money.

Anyways, I think we're having a misunderstanding. I think this discussion has fallen victim to a language barrier.

I used ExpressPCB for creating this PCB. It's free for anyone to use. Please note that I have NOT tested this board. I cannot take any responsibility for any damage it may cause.

I'm going to focus on another project. I wish you all the best on getting the HxC FDD emulator working with the Marty :)

Take care,

Brian

Yes, I see you used ExpressPCB, I used it me too in my early days of designing, now I'm very happy with Kicad.Anyway, first we have to figure out why the HxC emulator doesn't work in a Marty console, very kindly Jeff has offered to help us with his huge skills.

Yes, pardon, I didn't want to say your device doesn't work with Marty, probably something must be chnaged in firmware.

I still have to send it, I'm very busy in this damned real life... :D

On your pinout i see 3 interesting signals : Disk Change, Ready and HD Out.
Also : with the latest firmwares you can emulate the motor-on input by connecting the MTRON signal to the HxC drive B selection input (ID0-B...) . This allows a proper emulation of the Ready signal. Some rare machine need this. The Marty is maybe one of them.

If you mean the latest firmwares the v1.8.2.40 and beta ones, I already tried them and also connected the MTORN signal to drive B of the HxC without success.
About the three signals, I'm assuming the one I posted is the pinout of Marty FDD since here are no info available and I simply take the pinout of a generic 26pin FDD.But for sure it worked with a Samsung SFD-321B FDD set in 3-mode (so with READY signal instead on DISK CHANGE.HD-OUT signal can also e omitted and FDD will stil work)

Yes, I meant both in hardware and software.I will try again anyway.Thanks.
