I also checked the DB25 SCSI pins and they are correct. So the only consequence is that I can not use a standard 40 pin ribbon cable to connect the rascsi to the raspi, but have to set the pins one by one with a bunch of duponts, right? Or I could cut the "wrong" traces and connect with some...

Hi, I finally got together all components and am almost ready for assembly. Just for the heck I decided to check the the raspberry pin connectors and I'm not sure I understand them. While D0-D7, DP, CD and ACT are where I expect them to be the rest of the pins are not. Looking at the original...

So I just received the PCBs (I ordered a batch of five). Now I am after the parts: I can get the transceivers at RS, but they do not have the resistor networks. Other suppliers charge enormous s&h fees... Can I replace the resistor networks with just 10 ordinary resistors each?

I did use a cheap USB microscope (about 15USD from China), but a good magnifying glass should do. Basically using a syringe you apply a very thin stripe of solder paste across the contacts, lay the IC on top of it, then heat the whole thing with the gun and usually everything goes into place by...

Actually I must say, after building a different project (TF530 Amiga accelerator card), that SMD is much more pleasant and sometimes easier than thru-hole. You just need a heatgun and solder paste instead of soldering iron and lead. I ordered a few rascsi pcbs from China, and should get them in...

Many thanks for the help. I just ordered a couple of din boards on dirtypcb. I shared the pcb, specifying the url of your github page, so everybody can find it there as well. Please let me know if this is ok for you. I believe I can get all parts at RS online, once the board arrives I will post...

Hi, I am considering building this adapter. I have a few questions though: 1) I would like to build an adapter to connect to the external DB25 SCSI connector of my SE/30, thus should I build the DIN version 1.6d? 2) what is the power connector in the other version for? 3) can I install a male...
