Modernizing a Vintage Apple Disk II @polymatt

polymatt Enjoy my first "real" video as I design, model, print, clean and hack my way through this build that was a super fun deviation from my normal work.

Sit back, relax, and enjoy the visuals. And don't forget to like, comment, and subscribe for more vintage computing content!

I took inspiration from a great project by @BitSplits and added my own tweaks and twists. This video shows my full build process of integrating a Floppy Emu by Big Mess of Wires into an Apple Disk ][ I bought off eBay "for parts".

The changes I made to Luca's design were to add an extension of the SD card into the faceplate so the SD card would be accessible from the front as well as optimizing the fit of the components and using snaps for the PCBs to minimize the use of glue.

Chapters:

0:40 - Soldering new leads to the Floppy Emu
2:09 - Removing the LED and soldering new leads
4:13 - Prepping the button breakout board and soldering leads
5:21 - Prepping the SD expansion cable and strengthening up the connector
7:22 - Disassembly and cleaning of the Apple Disk ][
11:58 - Prepping the face plate by soldering on new LED leads
13:44 - Designing the custom face plate (Shapr3D)
15:06 - Layout of the model & prepping for a print (CHITUBOXPro)
15:24 - 3D Printing the model, post-processing & sanding (Elegoo Saturn 2 8k)
17:48 - Painting the 3D model
19:43 - Test fitting the parts
22:21 - Wiring up the Floppy Emu for a pre-assembly test
24:19 - Testing the electronics
25:19 - Gluing the custom faceplate into the disk drive face
26:17 - Designing & Printing custom PCB standoffs for the Floppy Emu
28:28 - Putting the Floppy Emu in place and wiring up the face plate

Fixing an $800,000 Laptop?

polymatt 2024-07-14 | I got my hands on a really special IBM ThinkPad 360PE - One of the first convertible tablet computers IBM ever made. There's a famous one on eBay listed for over $800,000 at the time of this posting - but is it worth it? Or even close?

Let's take a look at this very cool piece of history and walk through the repairs that I need to do to bring it back to working order... which proves a bit more difficult that I anticipated.

Thanks to JOYALENS. They're not a sponsor but did send over the digital microscope used in this video that was a HUGE help. Here's where you can find your own: amzn.to/3LE4ucR

Bringing Back the 90s: The Gravis Ultrasound Card Remade!

polymatt 2024-01-12 | The Gravis Ultrasound is an iconic soundcard from the early '90s. Ian Scott is a maker who decided to do a faithful reproduction using a #raspberrypi Pico. Watch the full video for the interview.

The music in this short is used under the direct approval from the author.

It's an incredible track by Gusse / Digisonix. You can find his music on SoundCloud: soundcloud.com/gusse_dsx

Sound of the 90s: The Gravis Ultrasound Card Revival

You can visit patreon.com/polymatt to support my work and get early, ad-free access to my videos as well as other perks!

The Gravis Ultrasound is a long sought after card from the early to mid 1990s for it's unmatched ability to generate realistic audio with it's wavetable synthesis. Not many were made, not many games were supported but it earned a cult following.

Fast forward to 2023 and they're almost impossible to find at a reasonable price. Enter Ian Scott a.k.a polpo. He took his #raspberrypi project to the next level and built a faithful reproduction of the Gravis Ultrasound card... and more.

Let's catch up with Ian and see what the genesis of the project is and what might be next on his radar.

3D Printing an “Apple” BlueSCSI v2 Case

polymatt 2023-10-18 | With the #BlueSCSI v2 out, I had to think of a good way to make it blend in to my retro setup and a custom case seemed like the right thing to do! I love Apple's late 80s & early 90s design language so I decided to give it a shot.

In this video I'll show you how I laid out the case in CAD and the whole process for a 3D resin print including my techniques with color matching the resin. Hope you pick up on a few tips and tricks and enjoy the video!

Fully Restoring the Iconic IBM ThinkPad 701C Butterfly Laptop from 1995

polymatt 2023-10-02 | When @RetroGameCouch reached out and told me he found a rare 1995 IBM ThinkPad 701C laptop and asked if I wanted to do a restoration, I couldn't say no! I've worked on many of these over the years and even run a website dedicated to restoring them at http://701c.org.

Installing DOS 5 & Win 3.1: Nostalgia Overload

polymatt 2023-08-26 | Something a little bit different. I recently got invited to a friend’s recording studio (thanks Jeff!). We came up with the idea to record a bunch of old nostalgic sounds and what's more nostalgic than swapping floppies?

Retro Tech Exploration: Rare Cream-Colored ThinkPad 700C

polymatt 2023-07-25 | @home_computer_museum on Instagram sent these beauties over and I'm stoked.

These are two original 700C ThinkPads that were released in a rare "Cream" color and released in Germany (thus the QWERTZ keyboard layout). These weren't the only models released in a cream or gray color, but they were the first.

Can't wait to dig in and see if I can restore these back to their former glory.

Pushing the Limits: Ultimate Upgrade Journey of a Macintosh SE/30

polymatt 2023-07-19 | I often find myself wanting a hit of nostalgia by popping in an old game, but I don't want to deal with the hassle of swapping floppy disks or waiting for long load times. This is why so many of us use modern upgrades for vintage machines.

Repairing a SEALED vintage Mac

polymatt 2023-07-02 | Anyone who has had or worked on a Macintosh Classic knows that it's not IF it will fail, but WHEN and HOW BAD. Watch as I unbox this New Old Stock Compact Macintosh from 1990.

Will the analog board be too far gone? Has the battery exploded and eaten through half of the logic board? Find out if this mac is dead, or if it miraculously was spared from it's fate.

As a reminder, I provide a lot of detail throughout the video in the subtitles, so if you're interested, turn on Closed Captions - let me know who can find the @LGR reference ;)
