Hello my patrons! I'm finally catching up from my extreme sleep deficit after attending VCF Southwest in Dallas Texas. It was my first time attending that VCF (It was the second time VCF happened in Dallas) and the show-runners put on an amazing show. I had an absolute blast but as usual I ran myself quite ragged! When I got home yesterday around 1pm, I took a 7 hour nap! I then went to bed around midnight and slept another 6 hours! LOL! Now let's just hope I don't come down with any con-crud. (So far so good!) I have attached a couple pictures from the weekend -- it's always so fun to get to spend some time with my fellow content creators and then it's always such a blast to meet fans and other members of this awesome community!

If you managed to come chat with me during the show, thank you for saying hi! If you did snap a picture of us together, could you email them to me? misteradrianblack@gmail.com

I always forget to take any pictures so I totally rely on other people to share them with me!

Now onto the Plexus -- the video attached here is Part 5! The title kind of says it all -- but I do want to say that this won't be the end for this machine. I have been playing around with it quite a bit since making Part 5 -- although I think things are going to be a bit slow going now, so I'll likely work on some other videos for a bit. One of the things I tried to get working since making Part 5 is getting the BlueSCSI working -- but that was a big bust. Eric is helping me with it, but I'm going to need to get some SCSI protocol analyzer action going to make any further progress. Let's just say the SCSI stuff happening on the P/20 is ..... weird!

In other news, I did finally post dumps of the bootable hard drive image for the Plexus to the Github repo. There is a bit more stuff I'll be posting and then we should have everything needed to make a Plexus P/20 emulator, given someone has the right technical chops to figure out how to make that possible!

Ok I need to go unpack and do the normal post-trip stuff! Enjoy Part 5 and thanks for all the support!

PS: Welcome all new patrons! A ton of new people signed up since the Plexus P/20 series started! Thank you!!
