So the thing is, my retro cave is actually the far end of a smallish walk-in closet. This puts pretty tight limits on the amount of stuff I can fit there. However, I want all the DOS things from 1993-1997. And I mean all of it. And I want it on real hardware, at least as real as it can be.

So what I did, like a totally normal person, I made some architectural diagrams of what I would need to make it fit. It turns out using KVM switch, midi merge/thru boxes, and audio mixer makes things a whole lot easier.

Now I have 3 computers, every one of them is always connected to 4 midi modules, and all of them (both the computers and the midi modules) are individually controlled on the mixer. All 3 computers can also be running at the same time, although the KVM switch means only one can be viewed and controlled at any time.

What I’m most happy about this is, there is never a need to disconnect any devices or move any cables. It all just works without any hassle or setup to use any combination. For example, to switch from the 486/25 and MT-32 Old to Pentium MMX 200 and SC-88 I only shutdown the 486, power on the Pentium, switch KVM, and mute/unmute the correct inputs on the mixer.

Super happy with this setup, here’s a bit optimistic diagrams of the setup (the LaserWave 16 isn’t quite working yet) but overall it’s accurate. The gray box indicates the still missing last midi module, still looking for reasonably priced CM-32L in Europe.

And no this is not what I had in mind first, this diagram and setup has been evolving some years now. Getting close to completion now though, so I thought I could post this setup here already.

And yes, there is a whole giant spaghetti bowl’s worth of cable mess behind, I think I hid that pretty well taking picture from low angle.

Love it! I’m slowly working towards something similar. I recently got that same mixer and it’s an absolute game changer for multi sound card/device set ups.

I’m a big fan of the system schematic you made. Well done!

Absolutely awesome! And as any totally normal person, I loooove the schematic drawings.

Five thumbs up!

If it's dual it's kind of cool ... 😎

Did a bit cleanup on the diagrams, or did I make it worse? It looks clearer to me but then again I've edited it so often in couple years that it's never been unclear to me.

Still to do on the setup:

  • Wait for the CT4550 to arrive in mail, ditch the wonky Terratec Base-1 from the Digital
  • Wait for molex power big->floppy -adapter to arrive in mail, then remove IBM's current spinning hard drive and put the CF adapter in
  • Wait for the 5,25" drives to arrive in mail, and install one to Compaq
  • Transfer the LaserWave drivers from the 5,25" floppies to 3,5" floppies, install to IBM and finally some digital sound out of it
  • Get the CD-ROM working on the IBM
  • ...
  • Get a CM-32L maybe some day

Very nice schemas and setup.
Maybe change one of the awe64 for sb16 so that you have opl-3 as extra option.
Also you have five more inputs on kvm left I know where this is going 😁

Haha, I would definitely put more computers to this pile, unfortunately I run out of line mixer inputs. Now that I think of it though, I don't usually bother to mute the computer inputs, since very rarely two at a time play any sound. I could very well use another "dumb" audio box to combine multiple computer digital audio lines to one line mixer input. And it just so happens I do have one currently unused 4-to-1 audio switch box available (was previously on this setup, replaced by the way more convenient line mixer), which can also be configured to just play every input always out to the output. That would let me install 3 extra computers, hmm....

Some bad news about the LaserWave 16 sound card driver disks. It has 3 floppies, of which only number 2 was OK. Disk 1 had errors reading one file (programs.lzh) and installing the DOS drivers fails, and disk 3 which is Windows 3.1 driver disk, also had multiple errors reading the disk, and launching that setup failed with error. With these disks deteriorated and the seller unable to locate the original 3,5" driver disks - and the drivers not existing on the internet - it looks like I'm unable to acquire the drivers for the sound card. I'll have a few beers this weekend and re-attempt to align the floppy drive heads, although considering the fact that I was able to salvage contents of disk 2, it tells me that the disks 1 and 3 do have irrecoverable physical damage. So I'm out of hope but let's fix that with couple beers and give it another go nonetheless.

Meanwhile, to the plan B it is! Meaning:

- Installed the wonky Terratec Base-1 to the IBM (seems to work better on the IBM than it did on the Digital - at least no issues so far, fingers crossed)
- Forget the CD-ROM on the IBM, keep the more period correct 1.2 MB floppy on that instead
- Acquired 4X IDE CD-ROM, just in case I change my mind about that, expecting for it to arrive next week
- Might as well leave the other 1.2 MB floppy on the Compaq, that fills it up nicely with no free drive bays
- Might be getting the CM-32L too. At least I noticed one at an auction that ends in a week or so. It still costs an arm and a leg, but what's a few hundred on top of this pile, I'm guessing a few percent or so...

With the ACS LaserWave 16 kind of half-working, updated diagrams are basically only missing the CM-32L. Hopefully in a couple weeks or so that'll be fixed.

Love the shelf with all the big box software on it 😁

Thanks! That’s actually the most expensive part of this setup - there’s 3 shelves on front and a couple short shelves on the side. Games mostly, but also stuff like Windows 1.0/2.0 (not sure yet - box is 1.0 definitely but disks look like 2.0) and QB45 which I blame of everything that has happened to me since I got a PC in 1989. Thankfully mostly good stuff. Anyway, there’s most of what I used to play, still looking for quite a few items though I do need to build more shelves to accommodate all of those..

love it! i have a big box collection myself. Nothing better than a big shelf full of your favorite games.

Some updates on the 3-PC build, it's grown to 4-PC build.

- Added Pentium II for the Windows 98 stuff
- Ran out of inputs on the audio line mixer, so no room for the elusive Roland CM-32L
- Unfortunately I've been unable to get the 1.2MB floppy drives to work reliably, so they're out
- Added CD-ROM back to the IBM
- The IBM now fully works
- Actually, everything now fully works.
- Unsure what to upgrade or expand any more, so pretty happy about that.

This is an amazing setup. As you can imagine from my username, I am attempting similar.
Your solution is certainly an inspiration. Thanks for sharing.

In my case I am using a Pentium MMX to cover the 386/486 era, as it can be slowed down to those levels easily.
