Hot off the heels of their musical debut 6502 song the good folk at the Taylor and Amy Show are at it again. This time instead of assaulting our auditory senses, they play with our perception of color all while keeping the spirit of retro computing alive.
To back up a bit, I had the pleasure of witnessing the discovery of the Avon Beauty Vision Computer while at the Vintage Computer Festival Mid-West (VCFMW) this past September. We had visited the home of our friend [Jim W] from VCFMW who nonchalantly pulled down from the shelf the reddest computer I have ever seen.
A crowd quickly gathered at this newfound treat, designed and built before the invention of the Blue LED, was fallen upon and the process of prying out its secrets began. I was not privy to the negotiations, but I did notice a brightly colored red suitcase being exfiltrated by highly trained operatives later that night.
In a wonderful ode to tech nostalgia, The Taylor and Amy Show, comprised of YouTubers [Taylor] and [Amy], have released a new video “THE 6502 SONG”. This song had me singing along in roughly six clock cycles, possibly a little dancing around may have occurred as well. This isn’t just any chip they’re singing about; it’s the venerable 6502 microprocessor, the silicon heart behind iconic machines like the Apple II, Commodore 64/128, and the Atari 2600.
Their lyrics reminds me of when I lived for assembly language mnemonics and counting clock cycles, the “feeling” of a processor coming out of tristate to pronounce what it had learned in the last 500ns, and the undulations of the DRAMs like speed bumps. To top it off, portions of the song were actually recorded live at the Vintage Computer Festival Midwest 2023, where fans and computing history aficionados alike were treated to an impressive display of vintage tech.
What sets “THE 6502 SONG” apart isn’t just its catchy, melodic tune; it’s the expert blend of historical detail and genuine enthusiasm that resonates with everyone from grizzled assembly-language programmers to youngsters newly fascinated by the allure of 8-bit computing. With guest appearances from other female tech YouTubers like [Veronica Explains] and [Evie’s Revue], [AJ], [Jeri and Amy- Tilt5] and [FuzzyBad].
I believe [Chuck Peddle] father of the 6502, would be proud to see his creation live on and be appreciated so.
Our friend [Fran Blanche] recently recorded what it was like to participate in an energetic round table at the recently held Vintage Computer Festival (VCF) East. Fran joined well known personalities [Jeri Ellsworth], [Adrian Black] of Adrian’s Digital Basement, and Usagi Electric creator [Dave Lovett] with yours truly moderating.
The table-less roundtable discussed the pros and cons of streaming about retro and tech, and what its like to hang yourself out there in video format. Goals and motives differed widely from speaker to speaker and there was some good-natured ribbing about who makes money vs. who simply gets away with spending less.
Most of all fun was had by the speakers as they interacted with each other, and with the audience — and that comfort came across to the standing room only crowd of avid retro-enthusiasts who only told us good things about what they saw and heard that night.
One thing we did note was that every speaker actually knew what microphones were and how to use them.
A new Commodore C128 cartridge in 2023? That’s what [idun-projects] set out to do and, as you can see in the video below, did. I did the original C128 hardware design and worked with the amazing team that turned this home computer out in 1985. Honestly, I am amazed that any of them are still working 38 years later, let alone that someone is making new cartridges for it.
I also never thought I would hear about someone’s in-depth experience designing for the ‘128. The post takes us through [idun-project’s] decision to use the ‘128 and how modern expectations apply to allcomputers, even the old ones. Hot on the list was connectivity and reasonable storage (looking at you, floppy disks).
This year marks the anniversary of the most popular selling home computer ever, the Commodore 64, which made its debut in 1982. Note that I am saying “home computer” and not personal computer (PC) because back then the term PC was not yet in use for home computer users.
Some of you have probably not heard of Commodore, which is kind of sad, though there is a simple reason why — Commodore is no longer around to maintain its legacy. If one were to watch a documentary about the 1980s they may see a picture of an Apple computer or its founders but most likely would not see a picture of a Commodore computer in spite of selling tens of millions of units.
To understand the success of the C64 I would first back up and talk about the fabled era of home computers which starts with understanding the microprocessor of the day, the venerable 6502. Check out the video and follow along below.
You can do your own Surface Mount Technology based PCB assembly with just a handful of tools and some patience. At the heart of my SMT process is stopping to inspect the various steps all while trying to maintain a bit of cleanliness in the process.
Surface mount or Surface Mount Technology (SMT) is the modern way to assemble Printed Circuit Boards (PCB) and is what is commonly seen when opening a modern piece of tech. It’s much smaller than the older Through-Hole (TH) technology where the component leads were inserted into holes in PCB, and act we called “stuffing” since we had to stuff the components into the holes.
A few specialized tools make this a lot easier, but resourceful hackers will be able to pull together a solder paste stencil jig, vacuum tweezers, and a modified toaster oven with a controller that can follow the reflow profile of the solder paste. Where you shouldn’t skimp is on the quality, age, and storage of the solder paste itself.
Join me after the break for my video overview of the process I use in my workshop, along with details of every step of my SMT assembly process.
I miss my friend Dave DiOrio. He was a chip designer in the 1980’s, which made him one of the true wizards back then. We met my first day when I started at Commodore Business Machines, though my paycheck said MOS Technology on it.
MOS Technology was the birthplace of the venerable 6502 microprocessor, the VIC video chip, and the SID sound chip to name the really famous ones. It also brought us the TED Text Display chip, a whole boatload of Amiga chips, and several other chips that almost did what we wanted them to do.
I worked with magicians whose stock and trade were comprised of half-part quantum tunneling effect and half-part straight-up logic implementation. These magicians weren’t bound by the number of pins available for TTL logic, not like us lowly hardware engineers who had to string 14 and 16 pin chips together to do any real lifting.
Below the spartan offices where the designs were drawn lived the dragon otherwise known as a chip fab, short for integrated circuit fabrication plant. This beast ate sand and made wafers; slices of almost pure silicon in crystalline form with all kinds of intricate things craftily grown on top of them.
Memory Lane: Touring the Abandoned MOS Headquarters
MOS Technology was started in 1969 by Allen Bradley but only became the MOS that I think of when I talk about the good old days when Chuck Peddle and a bunch of cohorts from Motorola, including Bill Mensch, swept in and produced the 6502 microprocessor, which resembled a particular Motorola processor quite a bit, in fact a lot. Lawsuits followed.
Meanwhile the 6502 was taking over several industries as the go-to processor for everything from medical equipment to microwave ovens to home computers. It was while designing home computers that I met Dave while standing above a chip fab. I can still remember the smell of that dragon farting below our feet… its an understatement to say I miss those times.
A couple of years ago I had a chance to return to the old stomping ground as it were, and set foot (legally) inside of MOS headquarters in Norristown, PA — which had become CSG (Commodore Semiconductor Group) by the end. The basement was dirty and flooded and yet we found wafers, one from one of the computers I worked on.
The ground floor was dark and quiet, I stood at the dirty glass entrance doors looking out at a drab street and I quickly moved on before I got hit by some sort of self evident metaphor for life that would have been annoying.
The second floor was where our offices had been. The hot press of design deadlines has long since left this space, now all there is to see is the golf course out the window and a little camp fire someone had made. I got to show this video to Dave, including the view looking out his old office window, and we both smiled at the thought that it was now 35 years later.
Dave has since passed away, the world has one less wizard and as the video shows, the dragon has long since gone quiet.
