"Every day you may make progress. Every step may be fruitful. Yet there will stretch out before you an ever-lengthening, ever-ascending, ever-improving path. You know you will never get to the end of the journey. But this, so far from discouraging, only adds to the joy and glory of the climb." — Sir Winston Churchill

PC Mod Project: Retro XPS (Part 4)
Near-Final

I was able to install an older 3COM network card I had in storage, get it to work in DOS, and configure Windows 3.11 for Workgroups with Microsoft's TCP/IP to get it on my home network. It works! I since downloaded Internet Explorer 3.0 and an old Netscape version (Firefox not available for Windows 3.11) from oldversions.com. I also installed old versions of Macromedia Flash plugin, Adobe Acrobat Reader, Goldwave (for audio editing), and JASC's Paint Shop Pro. Everything works lightning fast for Windows 3.11. It's amazing how fast older operating systems can be when coupled with hardware newer than their intended usage. It completes similar tasks in Windows 3.11 faster than a Pentium 4 can accomplish them in Windows XP.

I also ran MemMaker on each one of my four boot configurations to optimize loading modules in upper memory and free more conventional memory. These configurations include gaming with EMS, gaming without EMS, complete DOS (doskey, CD-ROM driver, etc.), and complete Windows (CD-ROM, network, etc.). My gaming configs result in 604KB free of conventional memory, while my complete configs are between 560KB and 580KB of free memory. I took all of my old batch files, custom menus, etc. from my original retro PC and copied them over. Now the PC is complete software wise, but I'll be doing benchmarks and diagnostics on it just to test everything for the long haul. I definitely want to see the exact performance marks for the 266x CF card over UltraDMA-33.

Since many of the old games I have on this system use the default PC Speaker instead of a sound card, I ran a cable from the motherboard's PC speaker pins to the input on the sound card. Only older sound cards such as the Sound Blaster 16 ISA I am using have an input for the PC speaker and support a separate volume control for it. I reduced any possible RF noise on the line with the cable passed through and wrapped once around ferrite cores at each end. The quality of the sound output through Klipsch speakers dedicated to this PC is amazingly clean. Those old Sound Blaster 16 ISA cards had a surprisingly high signal to noise ratio given their date of manufacturing.

I still have acrylic fan grills (tribal-design) on order to replace the metal ones, but here's some pics of the near-final PC. These are both with and without the blue EL lights powered on:



PC Mod Project: Retro XPS (Part 3)
Painted Ribbon Cable

For floppy and IDE cables, the "round" ones out there are not really round, but rather ribbon cables stuffed into a round sheath. Some might actually have individual strands (as with some higher end round cables like Antec), but cheap ones are often just regular ribbon cables that are crushed and compacted into a round sheath. Therefore, I really dislike these cheaper round IDE cables. They just look and feel cheap. The quality round cables are rarely sold in a simple black color; even the pure black ones are not as simple looking as I'd prefer.

However, I've always enjoyed the look of the black, flat ribbon cables Asus includes with their motherboards. They seem so much more elegant and aesthetically pleasing when compared to "round" ribbon cables. Flat ribbon cables also have the added ability to lay flat against a surface, and make folds when changing direction or position. More importantly, flat ribbon cables can be shortened to any length, because adding a connector is simple with the right crimper and connectors.

Unfortunately, it's nearly impossible to buy black ribbon cable that is flat. I've tried to buy them individually, and I've tried to buy it in bulk. The consumer is out of luck here.

After researching and dumping too much of my time into something trivial to others, I found a simple solution that some have already known. Vinyl spray paint. I purchased a can of gloss black vinyl & carpet spray paint from my local automotive store, then pulled out a spare 80-conductor IDE cable to give it a shot. After taping off the connectors with blue painter's tape, I discovered that vinyl paint is really the best way to go! It bonds to the ribbon cable, looks better than the no-gloss black ribbon cables from Asus, and doesn't flake or peel when bent, twisted, and scratched. Whoot!

Here's a pic of the one I painted (80-conductor, dual drive) with Duplicolor Vinyl & Fabric Gloss Black, compared to an Asus cable (40-conductor, single drive). I also painted the various color connectors black with a paint marker, except on their pin side where they won't be visible.




Sleeving

As with any PC mod project, sleeving always seems to take longer for me than any other step. May be it's because I put so much love into my cabling, or may be it's because I now solder each connector when splicing or shortening cables. Either way, this step took even longer for this project because the black sleeving I used wasn't 'black' enough for me. It is nice sleeving, but one layer doesn't seem to black-out the color of the cables enough for my tastes. So all of my cables have two layers of sleeving.

Here's the results:

Component Housings

As with any mod I do, I painted the component housings (CD-ROM, FDD, and a junction box) semi-gloss black. This gives it a nice, satin-like finish, without being dull or shiny. I masked off the plastic LED covers of the floppy faceplate, and didn't bother painting the CD-ROM faceplate since it was already black. I did have to later apply some hand glaze to the CD-ROM faceplate to polish a little "wet look" into it to match everything else. For now, here are the painted covers and faceplates:




EL Lights

Since I strongly feel that CCFLs and clear acrylic cases are poor combinations, I'm opting to go with a little bit of EL lighting for highlights. It's a subtle glow around just the light strip/wire itself that adds a nice touch to clear cases. Of course my other alternative is to go UV with UV CCFLs, but I'm really bored with the whole UV craze. I'd much rather have something that looks like it came from the movie "Tron" than something out of a really bad Rave party.

The kit itself, both powered off and on:



Since the inverter for the EL lights emits a high-pitch whine, I decided the encase it inside my own enclosure. The whine seems to be curtailed when the bottom of the unit is sealed by a dense mat or rubber, along with some weight or pressure on the top to keep it sealed. Therefore, I put both molding tape and part of a rubber mouse pad under it, then stuffed it into an enclosure with foam to reduce the shrill sound leakage. I didn't want to use a clear enclosure here since the use of all the foam.




Voltage Conversion

For such a simple issue, this is by far one of the greatest portion and challenge of this project. The problem: many high-end, modular power supplies do no supply a -5V wire (white) to the motherboard, meaning they are unable to generate -5V at all. It isn't needed for newer motherboards, because only the old ISA bus (its controller) utilizes -5V. Some mid to low-end power supplies still offer this -5V output, but I have my mind set on an Enermax, SeaSonic, or PC Power & Cooling. I purchased an Enermax Liberty 400W for this project because of both its good build quality and its use of modular cables. Although I will be cutting and splicing cables as I see fit, I still enjoy the modular output design.

To accommodate my choice, I need to design and implement a separate device to output -5V to the motherboard. After some research, I discovered that an electronic component known as a 7905 voltage regulator will take in -12V (already supplied by a PSU) and output -5V. The only problem is, this is a PC board mount style component with connections that should be soldered. To make it worse, the voltage regulator itself is not enough for reliable operation. It needs capacitors on both its input (-12V) and output (-5V). And if that couldn't get any worse, I was never good at soldering and ditched the notion of it many years ago.

Fortunately, with the help of the community members at Electronics Forum, plenty of online research, electrical design software (KiCad), and many purchases at my local Radio Shack store, I was able to fabricate this voltage conversion unit, and even make it looks presentable in the process. Furthermore, I learned to embrace soldering and pick up hobby electronics.

I first double-checked the simple design in KiCad. It was complicated for me, being an electronics noob, so I wanted to make sure it looked right with those on Electronics Forum first.



I then tested everything in a breadboard before actually soldering together components. Instead of my KiCad plans, I decided to go with 22µF capacitors on both the input and output to ensure stability.



I used a clear acrylic card holder box as the housing of the unit to keep in line with my case's clear theme. I drilled holes in the side for binding posts, and larger holes at the ends to help with ventilation.



Top (component side), bottom (soldering and wire side), finished with lid off, and finished with lid on:




Power Supply

The power supply is one of the last components I'll have completed. The -5v issue, conversion from ATX to Dell proprietary power connector, and even sleeving have delayed it. I found a great reference for converting to/from Dell's proprietary power connector on someone's personal site. Here's what I've done so far with the Enermax Liberty 400W PSU for this build:




System Preview

Here's a quick shot of the front-panel pcb before I modded it. I ended up removing (desoldering) components, cutting down the height of it, and then painting it black as shown later. I did remove the front-panel audio and USB connectors before taking this image.
