The components are around $40+ the shipping of the boards from China (which is around $20 to get them in a reasonable amount of time). Would there be any interest in pulling together a group buy? There are a couple things I would change/do differently... - Use through-hole for the 50-pin...

Ok... wasn't as challenging as I thought it would be.... https://github.com/akuker/RASCSI/wiki/OLED-Status-Display-(Optional)

I thought the same thing! For this version, I broke out the i2c and VCC to a separate header to attach a super cheap OLED. I haven't got around to writing any code do do anything with it, but that shouldn't be too tough. You could also easily add a much larger screen, but I'm trying to watch the...

That is exciting!! The code might not be directly portable to the RaSCSI, but the understanding of the communication protocol is a huge win for the community! I'm running out of vacation time for this week, but this looks like something to tackle with my next vacation!!  I'd make a comment...

I did post in one of the Vintage Mac Facebook groups yesterday. That was me! Side note: I'm spending a bunch of time today trying to pull together a good documentation package for English Mac users. Feedback/comments/contributions are welcome! https://github.com/akuker/RASCSI/wiki

ITS ALIVE!!! I did some benchmarks with a few different Raspberry Pi versions (the Raspberry Pi 0 results were surprising). I compared them to the stock Seagate HD in my Quadra 840av and a SCSI2SD version 5.0a that I had from a few years back. https://github.com/akuker/RASCSI/wiki/Benchmarks...

Very cool project!! I'm excited to see how it turns out!

FYI.... status update.... Found an issue with the modified circuit board I made. I had the "ACK" and "ACT" lines swapped. Oops! This was easy enough to fix with a cut/jump on the board though. I was able to get the RaSCSI software running on a Raspberry Pi 4. My Quadra is able to see the...

I recently got my Quadra 840av working (best dumpster find ever!). I'd love to upgrade the VRAM to 2MB. Looking at the VRAM modules on eBay, they just look like a couple SRAM ICs with some bypass caps. Has anyone ever tried making their own VRAM PCB?

Thanks Michael! Any tips on what was wrong with the circuit?

Hi all! I'm going to jump on the RaSCSI bandwagon here. I've order a few of the cards designed by K55 (and also tried my hand at a customized version that has both 50pin ribbon and 25-pin DB connectors). Hopefully everything will be here by the 4th of July so I can dig into this. Just curious...
