se/30 dual slot PDS Gerbers

[Chopsticks]

Hi everyone,

late last year i decided to fiddle aroud with kicad to learn how it works compared to eagle.. certainly not an expect in either. regarless i decided to made a dual PDS slot adaptor for me SE/30 so can use my network card and my gfx card at the same time...
my network card doesnt have a pass through slot and i didnt want to have to choose one card over the other

the dual slot card works well though i do want to tweak the mounting holes a few mm slightly, regardless I just wanted to offer the Gerber files in case anyone else is the same boat i was with dual cards.
long term i plan to release the kicad files on GitHub under open source.. in the mean time if anyone builds this and has any feedback or issues regarding design i would be greatful for the feedback.

edit... i attached a couple pictures of V2, currently ive made v3 that adjusts a few dimensions as well as the angle of the PDS slots to better fit taller cards but i cant find pictures right now.

its a pretty simple 4 layer card but hopefully its useful to some on the forums here.

Super awesome! Will you make the v3 Gerbers available as well?

 

[Chopsticks]

Yes another version will be released at some stage... i've been thinking of possibly adding a scsi SD card solution to the board though so it could be awhile before i had time to do that, and i need to make sure the opensource licences used buy any scsi sd-card solution allow me to do that if i use an opensource license for this board.

the files i attached above work fine they are the current version.. clearly i didn't proof read or realize i had uploaded V2 and not V1 pictures.

what i should have said was as follows:
"edit... i attached a couple pictures below, currently ive made v2 that adjusts a few dimensions as well as the angle of the PDS slots to better fit taller cards "


super sorry for not being clear about that..

First off, Chopsticks, thank you for designing this and being so kind as to release it!

I had your board made by PCBWay and bought the 3x connectors from Mouser. Put it together today, and have run into a weird issue... So, my video card (Lapis ColorServer) works in either of the slots, as does my ethernet card (Farallon), but when they’re connected simultaneously, neither of the cards works or even appears in TattleTech…

I’ve tried another ethernet card (Dynaport E/si30), and also connecting both ethernet cards at the same time - same result where neither card is seen. Have I made an error in assembly, could the connectors be incorrect, or...? Any suggestions appreciated, thanks in advance!

The three connectors I bought are these:

PS: Tried in two different SE/30s, same symptoms in both...

On PDS cards, because there's only one PDS slot, the "virtual slot ID" that the card uses is set on the card, not on the slot. So if you have two cards that are set to the same slot ID, they'll fight each other and neither will work. You might want to check this (tattletech will probably tell you what slot ID they think they are); one or both may have jumpers to select which slot ID is in use.

Thanks for your reply, cheesestraws. Had wondered if it was an ID conflict! As it turns out, none of my cards have jumpers unfortunately. I think I have one more ethernet card, I'll check to see if that one does. Thanks again

 

[Chopsticks]

It’s likely what @cheesestraws mentions above about having the same slot ID’s.
Some pds cards have pin headers to select slot ID and some have presoldered jumpers thst would need removing/swapping

Being the a single card connected to either slot runs fine I’m sure you’ve assembled you card fine. It’s just a basic passive pass through board anyway.

I’m not 100% but you might have slotID pins next to R14/R15 on the lapis color server board
edit: actually it would more likely be JMP3 left of the main XILINX FPGA. It’s hard to tell from the pictures I’ve looked at but it appears the middle and right pin are connected together. I wouldn’t be surprised it you cut the connection between pin 2 and 3 and install a header and put a jumper on pins 1 and 2 that it would probably charge the slot ID.

Thanks, Chopsticks I do see JMP3, the middle and right are connected currently, yes. Pity there doesn't seem to be any documentation for these jumpers anywhere. I'll experiment over the weekend and see what I come up with. Thanks again, much appreciated!
