Sounds good! Will you include the other components in a kit form or do we need to order these separately?Also... FYI for everyone.... The boards are being made! Once I get them, I'll probably throw them on Tindie to help distribute them.
(Note: these are only PARTIALLY assembled. Only the teeny tiny surface mount parts are being installed by JLCPCB)
This is something I'm planning on playing with when I get a board and some time.Love it!
maybe off-topic, but is anyone looking at using RaSCSI for networking?
Does it use a normal FAT file system that can be read on a computer? I think a lot of old music gear like this had proprietary file systems. Probably a simple one, but I think there'd be some coding needed.I want to try this on a Roland vs audio workstation.(VS-1680) It has an external scsi bus. Does anybody know how much cpu is used on a pi3 or pi4 when running Rascsi?
I'd like to be able to use the spare cycles to convert the files from propietary roland format to stand wav files if there is sufficent cpu time available.
I see the appeal to have it powered by the SCSI bus, but I don't see how it can be done practically.I think it would be possible for terminator power. However, as mentioned before, the Raspberry Pi needs to be up first before the Mac.
Powering the Raspberry Pi using the terminator power would be possible if the Mac has a lot of RAM, and thus takes a while doing the RAM check, giving time for the Raspberry Pi to start up.
great, that would be an awesome addition to be able to connect to networks and the internetThis is something I'm planning on playing with when I get a board and some time.
I'm still reading about this, and wondering if I'm mis-reading or misunderstanding something. I'll check the TERMPWR on my SE this weekend. If it's there, I should see 5v on pin 25.I see the appeal to have it powered by the SCSI bus, but I don't see how it can be done practically.
The Mac II, SE and Plus use an NCR 5380 SCSI controller. The controller outputs have a max voltage of 2.4v, and 48mA. In addition to the low numbers, the SE, Plus and II don't provide termination power. Even if there was a way to scavenge power from some of the other lines, The Pi Zero W needs at a minimum 80mA, and to get the power draw that low, you sacrifice a bunch of functionality.
I think powering stuff via the SCSI ports would hinges on termination power being available. But since the computers this is initially targeted at target machines don't provide TERMPWR, building any circuitry to leverage it, and building a environment to boot up quickly would yield very little gain.
What could be useful is a separate unit, something akin to a parallel port pass through dongle type thing. It could scavenge the TERMPWR and feed it into the RPi via an external cable, or whatever. With a separate unit, it's modular, and could be used for this or any number of other projects.
I believe it's a single missing diode that there's even a place for on the board.It can be enabled by adding a couple missing components I think
