What are you guys doing for your DIY S100 system cases?

I'm putting together a small S100 system with a 9 slot backplane. I am using a mini S100 front panel. It is mainly for a bench system to test other S100 boards, but also just a general system to tinker with..

Pictures would be awesome.

THanks

This is my system as of 2017. It began life as an empty CompuPro Case purchased from Priority One Electronics back in the 80's and sat unused until I could figure out all the bobs and pieces to get it working. Hardest part (for the case design) was the front panel lettering; I never could produce decent looking panels. Early last year I discovered transparent "water slide decals" that are printable on a laser printer. These work great once sealed with several layers of clear coat finish. Andrew Lynch and John Monahan provided the board designs and finally everything worked. Took a while, but I am now trying to get my other old S100 cards functional.

This is ostensibly my first S-100 system from college, and continues to be one of my most used fixtures:

It's a Morrow Wunderbuss backplane and a Lambda triple voltage supply. The Lambda supply allows you to adjust voltage and current limit -- excellent for testing boards with unknown tantalum capacitors. Here it is, being used for debugging a Cromemco 4FDC and writing out floppy images:

And again, testing out some Digiac boards for geneb:

Notice it's sitting next to the IMSAI, which while awesome is slightly less useful for at least the first leg of debugging.

I'm working on a S-100 kit chassis, targeting the 9-slot s100computers.com backplane but set up so you can put anything up to about a 12-slot backplane in there. The motherboard and card mounts are secured to strut, so you can move them to accommodate pretty much any configuration. I'll probably end up doing a small manufacturing run, but the plans will be open sourced and the average hobbyist with a jigsaw, drill, flat file, and a bunch of patience should be able to recreate it from mostly hardware store bits. Hope to have a working model before winter. The case project solves what I see as the last real missing bit to building S-100 systems, since we've got a great workable board set from John Monahan and everyone else on the s100computers.com list.

Current baseplate size is 12 inches deep by 18 inches wide. I chose a sheet of 1/4" aluminum, it does not flex :)

I built my 8080 machine back in 1978, about then. It started out with only one Uart powering an ASR35, 1K of memory. Evenutally it was a model for some controllers I built for work. Over the years my family toke me away from this, but since I have retired I dragged it out and got it working again, although only during the cold winter months.

The 8080 is the black panel, it uses the two 8" drive above it. Below the 8080 is my PDP8E.

My system (which new_castle_j graciously sent to me so I could work on an S-100 computer) has a case that someone hand-crafted from wood. It came with the name "The Oaken Beast."

I measured the case and wrote them up as blueprints here:

Nice clean well laid-out CAD drawings, what did you use to draw them?

Thanks. I used Solidworks.

Does the card-rack slide out as a tray (with some sort of latch), or does one have to bolt/unbolt it all of the time?
