Scuznet SCSI to Ethernet Adapter PCB & parts kit


Recommended Posts

  • 68kMLA Supporter

I had ten Scuznet PCBs manufactured, and have purchased the parts necessary to assemble fifteen boards. The cost of the components for fifteen boards was just shy of $400, and the PCBs had an effective cost of $5 each, so I'm asking $35 per kit, shipped via first class mail (trackable), within the US. I'm not sure what it will cost to ship them internationally yet, but I'd anticipate about $10 each. I won't have all the parts in-hand for another week, probably.

 

This is an open source project designed by Saybur. The code and PCB layouts are available at https://github.com/saybur/scuznet.

 

This is not a beginners' build. It is comprised of 91 discrete compoents, many of which are size 0603 SMT passives.

 

It uses an existing SCSI Ethernet driver, the Nuvotech Nuvolink Driver, also available at the Compgeke Archive

I’m interested, but unless I’m misreading the threads, a PDI programmer is needed to get it up and running. I spent a bit of time looking around and wasn’t really able to find much for those. Do you have any suggestions (or perhaps search terms I’m overlooking)? Or, perhaps, am I just misunderstanding the situation? Thanks.

Very cool. Which Macs will this work on? 

Any SCSI mac running a version of System/MacOS that is compatible with the existing driver, I'd imagine. Not sure about PowerPC, but it would probably work there, although there are frankly better options for networking on almost any PPC Macintosh.

I'll be selling the ATMEGA pre-programmed.

Nice...

And it does look tempting, but 91 pieces and some really small SMD...

I'm not there yet...  ;-(  (Even tho that little voice inside my head is telling me to go for it..  But he's the same voice that told me there was no way VHS would win and I should buy Beta, so I don't generally listen to him anymore..)

Link to original thread's down. Out of curiosity, how does the Snail's speed compare to Asante Cards on the 030 PDS? If I could manage the build, I'd probably get one for my SE that's chock full of Radius cards just to get it a Wifi antenna on the breakout board up and running.

Here's a working link,  the "friendly url" links are still messed up so old links in the forum/google results are broken

The protocol used by the SCSI driver is well documented by saybur on their github.

I don't see why that documentation couldn't be used to add ethernet over USB to scsi2sd.

 

Of course the moral problem with that is it's effectively diverting money away from anyone who would buy the Scuznet board.

I want to get this done before I lose interest, so I'm having 10x PCBs manufactured and ordered 1 set of parts from DigiKey. I didn't realize there was a box and power adapter included in the CSV BOM, so that added ~$30 to the cost. If you buy in 1x quantity, the total cost (without case or 5v adapter) is about $39 for parts from digikey, plus $2 per PCB.

 

If anybody would like to buy one of the 9 spare PCBs for this, PM me and I will sell it to you for the $2 cost + ship cost.
