Commodore PET/CBM 2001 - Papercraft Design

The link to the PET papercraft can be found at the end of this post.

The Commodore PET has consistently been one of the most requested models but I have held off on making one as there already was a pretty great one on the internet. About a half year or so ago, I noticed the link to that model had broken and I took that as a sign to make my own.

I grew up with a Commodore 64 and I had seen a few VIC-20s but when my Computer Science teacher brought in his Commodore PET, released in 1977, I went bananas for the thing. The styling of this machine was so striking, even in its day, there weren’t many computers that could rival the presence of this machine. The first thing that struck me was the size of this beast, a footprint rivaling the PC XTs we were using at the time, and topped with the funkiest blue trapezoid you’ve every laid eyes upon. Following that, my eyes were drawn to that amazing/awful calculator keyboard. I am typing on a Apple chicklet-style keyboard today, but it doesn’t begin to reflect the sponge and springs experience that was the PET. The fact that all the keys were in a perfect grid pretty much made touch typing impossible. The keys on my teacher’s computer had received a generous coating of clear nail polish. He told us that this helped to keep the printing on the keys from rubbing off. I only used it for about a minute but if this isn’t the worst keyboard in the history of computers, I’d be curious what could be worse.

Commodore’s Floppy Drives were almost as large as the actual PET.

Our teacher had also brought in a disk drive and also brought in a few 8” floppy disks for us gaze at in disbelief. All in, my time with the PET measures in mere minutes, but the impression can still be seen today. I don’t know if I would ever have developed an appreciation for vintage computers had it not been for my time with that computer. I wonder if I would have ever made a single paper model if I had not been in that class thirty some years ago.

The PET ecosystem is quite large, so there are plenty of accessories included in this design.

Once again, I need to give an extra special warm shout out to my good buddy George, who selflessly took time out of his life to help me test fit, assemble and photograph all the completed models in today’s post. He’s a testament to how clean my models can look. :)

Also, as I continued to research the design of the PET, I came to realize that when including the CBM line there are at least a dozen slight variations on this machine, with different badging, cassette players, colours, etc. While only two PET designs are shown in these photos, there are a total of four variations included in this pattern, including a CBM machine with a full-sized keyboard.

Even though this was the early days at Commodore, I can see how this setup will have inspired many pioneers in the industry with it’s 2001 good looks and Pet Rock charms. The number of games that were produced for a machine with such a limited display is also impressive. I have also included a series of swappable screen plates so that you can have your model play all of your favorite games.

All lined up!

Please tell me about your experiences with the PET by commenting below. What other systems should I turn into a papercraft? Please leave a like if you like.

Thank you to my Computer Science teacher and George for inspiring and helping brings these surreal tiny experiences to life. The link to the Commodore PET/CBM 2001 can be found here.

Bergen - New Vintage Chronograph Design

I am starting to see some positive momentum on the watch design front. Each time I re-approach this octagonal case shape, I happier with the refinements. The latest design in this series is a unique take on a vintage bicompax-style chronograph. This design is meant to house a Seagull ST19 chronograph movement, a clone of the Venus 175.

Through the development process, I compared a good cross-section of the current-day chronographs that use Seagull ST19 and vintage watches that made use of the Venus 175. Whether it was new Hong Kong Ed or a vintage Breitling Toptime, none of these chronographs was using a case shape this unique.

Bergen “New Vintage” Chronograph is designed to use Seagull’s ST19 movement.

The movement fits nicely inside the case design. I will concede that the irregular case shape may impact the functionality of the minute track as it stands but I will take some time away from this design, hoping I will revisit with fresher eyes.

Below are some of the latest iterations of the New Vintage Sports (formerly the Octo) watch design, more specifically the 100th iteration.

BBC Microcomputer - Papercraft Design

The download to the BBC Microcomputer model is available at the bottom of this article.

I grew in Canada in the 80s and spent my elementary school years surrounded by Apple II computers. While not an official government scheme, I suspect many North American school kids my age will have seen the Apple’s as the school computer, often having cheaper 8-bits at home.

In the UK, the push towards computer literacy was a deliberate government effort. Computers were seen as the future and that every child should know how to use one. As a way to help realize this, a call to action was issued to all the major electronics manufacturers to help create a BBC branded microcomputer that would be distributed to school’s across the country.

Sinclair Research were seen as the obvious choice for the job but through a series of mishaps, the award was ultimately given to former partner turned rival Acorn Computers. Anyone who is interested in learning more about this whole fiasco, I suggest checking out the endlessly entertaining movie, Micro Men.

To accompany the release of Acorn’s new BBC Microcomputer a BBC television program aptly called The Computer Programme, helped lead kids through the inner working’s of the BBC Micro or Beeb for short.

The Beeb was produced by new kid, Acorn Computers.

I surveyed a few online communities to find out which computer model I should design next and the BBC Micro was a standout winner. Without access to the online resources, I might have neglected to recognize this computer for the powerhouse it was. Not only was it powerful in its day, it also helped to foster a spirit of digital exploration that can still be felt today. The ARM processor, which is still an essential part for the computer landscape descends directly from the chips Acorn design for the BBC.

Today, the UK born Raspberry Pi exists to help educate students both all over the world and is a permanent fixture in my living room. While I may miss some of the retro goodness of the machines of the 80’s, it is nice to know that similar experiences can still be had by current generations through cheap home computers and ever improving emulation.

While the BBC Micro was known as the education computer, it had plenty of games like Frak seen above.

My personal experience with the Beeb is largely relegated to YouTube videos, the aforementioned Micro Men movie and the excellent talk, The History of the British Home Computer by Author and Tech Historian Tom Lean.

If similar efforts had been made in Canada to educate the youth back in my school days, perhaps my passion for retro computers would be more widely shared inside my country. As it stands, I am glad that there is a reverence for these machines in other parts of the world and that with easy access to a global community, these passions can be shared anywhere.

Promo materials and companion manuals were a popular source of information.

I hope you enjoy building this model as much as I enjoyed making it. In many ways this might be the closest I ever get to touching a real BBC Microcomputer. Please consider dropping a like and sharing your personal experiences with this machine in comments below. I am always looking to learn something new!

Apple Macintosh 128K - Papercraft Design

The free Apple Macintosh papercraft pattern can be found at the end of this post.

The Macintosh came out in January of 1984, just one year after Apple launched the ill-fated Lisa computer. While Lisa introduced early adopters to modern computing, the Macintosh brought these concepts to the masses. Using a graphical interface with a mouse and keyboard is something we take for granted today but in 1984 it was bleeding edge.

View fullsize

The side of the Mac is interesting. I have been informed there is a programmer interrupt switch which can be clipped through the vents. This monitors machine code and is useful in programming. I thought it was a power switch but the community has spoken! :)

I can’t pretend I have a lot of experience with these early Macs. We had Apple II’s in my elementary school and when I was in high school we learnt on XTs and later on 386s. The first time I saw a 128K Mac with my own eyes was in 1996 at my university in one of the computer labs.

Despite have no hands on experience, there is no denying the appeal of this Mac’s form factor. Many of the innovations that appeared in the Lisa a year earlier are back - refined and ready for prime time. It is easy to see how this machine would help usher in a new era in modern computing.

View fullsize

The Mac 128K came with Macwrite and Macpaint. Neither of these are around these days but they served as inspiration for software we commonly use today.

Apple’s packaging also received a more modern look when compared to the Lisa materials. Brand standards were tightened up some to provide a more consistent look and feel throughout. The time-honoured tradition Apple of including Apple stickers with their products seems to have been born with the Mac 128K release. Also, Apple was happy to help you finance your new Mac purchase with their very own Apple credit card (Apple Pay was not the first).

Possibly the most interesting items, were the cassette tapes that Apple provided as a quick start guide for the Mac OS, and the included MacWrite and MacPaint. A multi-media experience was much more literal in 1984 and so creativity (and a cassette player) was required.

Once again, special thanks goes to my buddy George. He assembled and photographed all the items in this post. With the pandemic keeping me at home, I don’t have access to all the things I need to make these posts. George is both a professional photographer and master paper folder which makes him a valuable and highly skilled ally. You’re the best!

I did my best to limit the game selection to ones that ran on a 128K machine.

I hope you enjoy building this Macintosh 128K. The Apple community has always been super-supportive of my efforts so I am always happy when I can give something back.

For my next papercraft projects, I am working on a highly-requested British computer, and then a highly-requested US computer, followed by another non-computer (but retro) papercraft just to mix things up a bit!

Commodore VIC-20 - Papercraft Design

This Commodore VIC-20 pattern can be downloaded at the bottom of this post.

I wanted to send out a tremendous thank you to all the new followers and visitors to the site. I know many people might be looking for: 1. unique things to do 2. at home 3. on a limited budget 4. using available supplies. I feel these models are a great way to spend an evening and learn a thing or two about retro computers. Possibly even build your own retro museum. I try to stay as close to the source materials as I can using images that I usually source from the internet.

Due to the current global health crisis, I am working from home and don’t have access to the tools I use to test build and photograph these models. An extra special thanks to the always amazing George Blanc for doing a test assembly and providing me with the excellent photos for this post. If you are ever looking for a great product photographer (or paper folder), he is one of the best.

I created a Commodore 64 papercraft model as one of my first models and based this VIC-20 model off of that design so all the accessories shown should work with the C64 design as well.

The accessories with this model are size compatible with my earlier C64 design.

When my girlfriend told me she used to have a VIC-20 I did an image search for the different breadbins and asked her which one she had. There were at least three possible candidates but she was probably 10 when she last saw the computer so I decided to make all three (George folded and glued them all - you rule). Apologies to my German fans, I have not made the VC-20.. yet.

Three variations of the Commodore VIC-20 breadbin to suit your personal nostalgia.

Designing early 8-bit home computers can be an interesting experience. Many of today’s standard components like monitors were considered nice-to-have’s in the early 80s. A branded monitor wasn’t marketed to consumers at first so I did my best to replicate the television shown on many of the VIC-20 boxes that graced store shelves. Anyone care to guess what the specific brand/model of television in being used?

It’s always a challenge to say when enough is enough as far as the level of detail is concerned. I love doing little accessories like disks, cassettes and in the case of this VIC, some cartridges. The cartridge bay on the back of the pattern is not by default able to accept these cartridges. I try to consider the scale of the models and a general audience when making these designs and I think even George may have balked at the idea of making three keyboards with working cartridge slots. That being said, plenty of people have taken my patterns and pushed them further by making all sorts of working drive bays and ports. It is possible to adapt my designs with some extra imagination. If I had more time, I would release variations of each of these patterns to cater to different skill-levels. As you can see, the papercraft collection keeps growing so given enough time, I feel anything is possible!

Hopefully I can get my girlfriend a real VIC-20 someday soon but in the meantime I hope she will accept my (erm, and Geroge’s) gift of the papercraft VIC.

Thanks again to the community for your many suggestions of computers to do next. I have assembled a list of the “Top 5 most-requested computers” and was surprised and excited by what I saw. Do you want to know what the next five designs are going to be? Let me know in the comments below. I am willing to share but can keep it a surprise if that’s what you’d prefer. ;)

Sinclair ZX Spectrum - Papercraft Design

The ZX Spectrum was all but absent from the Canadian market in its heyday but that didn’t mean I wasn’t interested in the system. I have watched enough hours of gameplay on YouTube to get that many of the games developed in the UK were merciless usually requiring pixel perfect precision under cruel time constraints. While “Nintendo Hard" may be an honoured title amonthst many North American gamers, “ZX Spectrum Hard” appears to be on another level entirely.

Sir Clive is my favorite tech maverick.

Chucky Egg is pretty awesome.

When I design a new papercraft pattern I create the computer itself, any key peripherals and a monitor. The ZX Spectrum release pitch was that a family could save money by using a household television and portable cassette player over expensive proprietary devices.

Needing to think outside the box, I consulted the 1982 Dixons Summer Catologue and it recommended bundling “your new ZX Spectrum with the Contec KTN-3732 Portable Color TV and the Dixons TR12 Cassette Recorder”.

My 8-Bit Future

The Living Room *ruffed* out. Bruce, the Blue Heeler, says hello.

Trying to distinguish feminine from masculine in 8-bits is a challenge.

Faux's trailer is the world map. The limitations of the NES will ultimately determine the level of detail I am able to give to this world.

NES 8-bit game design has always been on the bucket list. I am hoping NESmaker will be the key to giving it a go. Getting familiar with a different graphics mode is always exciting to me, and the opportunity to tell a meaningful story with an old Nintendo makes the whole prospect that much more attractive.
