<div dir="ltr">Hi folks!
<div><br /></div>
<div>I've been working on a replica Sun 3/60 based on the online available schematics, and I finally can report some success! I have a board fully booting off network, this is what it looks like: <a href="http://www.whitebearcafe.com/img/PXL_20250521_060410660.MP.jpg">http://www.whitebearcafe.com/img/PXL_20250521_060410660.MP.jpg</a></div>
<div><br /></div>
<div>I left out quite a few things because I had no confidence this was going to work; there were quite a few errors in the schematics. I ended up with:</div>
<div>- only implementing the min required 4mb of RAM</div>
<div>- left out the SCSI and Video sections</div>
<div>- only put in the serial controller for A/B, left out the keyboard/mouse</div>
<div>- TTL serial, I didn't implement full rs232 or modem support</div>
<div>- left out the coax ethernet entirely</div>
<div>- no FPU</div>
<div><br /></div>
<div>Everything else is there. I can boot with a regular boot prom image, pass all the diag tests, boot off the network and load a kernel.</div>
<div><br /></div>
<div>I'll upload the newest version to github and arrange some things better. If I make a new version the top of the wishlist is 4MB simms, not putting more RAM in from the start is my main regret.</div>
<div><br /></div>
<div>All the components were available off Digikey or eBay, with only one PAL slightly on the rare side.</div>
<div><br /></div>

<div>PS: I still don't know who runs <a href="https://www.sun3arc.org/">https://www.sun3arc.org/</a> I'd love to buy them a beer or cake, that site was a lot of help. If they prefer to stay anonymous I'll donate to polar bears on behalf of the site's name or something.</div>
