VCF East Wrapup MegaPost


VCF East, the fabulous retrocomputing festival held in Wall, NJ this last weekend was a blast. We had a great time, dropped t-shirts and stickers to just about anyone who wanted one, took a lot of pictures, and shot a lot of video. Now that it’s over it’s time for the post-mortem, with one insanely long post.

We saw some very cool stuff that merited its own post, and much more that we simply didn’t have time to video. The previous posts from VCF East:

There’s still tons more, including a tour of the retrocomputer museum that hosted VCF East. The biggest talk was from [Dave Haynie], lord of the Amiga giving part three of a multi-year talk on the soap opera that was Commodore International.

VCF East: PR1ME And AT&T Unix Boxes


At the Vintage Computer Festival last weekend, there was a wonderful representation of small 8 and 16-bit home computers from the 80s, an awful lot of PDP and VAX-based minicomputers, and even some very big iron in the form of a UNIVAC and a Cray. You might think this is a good representation of computing history, but there was actually a huge gap in the historical reality. Namely, workstations and minicomputers that weren’t made by DEC.

[Ian Primus] was one of the very few people to recognize this shortcoming and brought his PRIME minicomputer. This was a huge, “two half racks, side by side” computer running PRIMOS, an operating system written in FORTRAN. Of course this made it extremely popular with engineering teams, but that doesn’t mean [Ian] can’t have fun with it. He had two terminals set up, one running Dungeon (i.e. Zork pre-Infocom) and a text-based lunar lander game.

Because the VCF East is held in New Jersey, it’s probably no surprise a few vintage AT&T Unix boxes showed up. [Anthony Stramaglia] brought in a few very cool vintage Unix workstations, dating from the early to mid 80s. In the video, he shows off two AT&T boxes. The first is a UNIX PC, containing a 68010 clocked at a blistering 10 MHz. Next up is the UNIX PC’s bigger brother, the 3B2 400. This is the workstation found on just about every desk at Bell Labs in the 80s, meaning this is the same computer [Ken Thompson] and [Dennis Ritchie] used for their work on UNIX.

VCF East: Old Computers, New Games


While the vintage computer festival in Wall, NJ had just about every vintage app you could imagine – multiple varities of *NIXes, pre-Zork Dungeon, BASIC interpreters of all capabilities, and just about every game ever released for 8-bit Commodore systems – there was, perhaps unsurprisingly, a distinct lack of modern programs written for these retro systems. Yes, despite there being people still curled up to keyboards and writing games for vintage systems, modern software was a strange oddity last weekend.

There were two wonderful exceptions, however. The first was Fahrfall, a game for the TRS-80 Color Computer. We’ve seen Fahrfall before when [John Linville] wrote it for the 2012 RetroChallenge Winter Warmup. The game itself is a re-imagining of Downfall for the Atari Jaguar, with the graphics scaled down immensely. The basic idea of the game is to jump down, ledge to ledge, on a vertically scrolling screen. Hit the walls or the bottom, and you’re dead. It’s a great game that probably would have sold well had it been a contemporary release.

Next up is a rather impressive port of Flappy Bird for the TI-99. The video does not do this game justice, although part of that might just be the awesome Amiga monitor used for the display. This game was brought in by [Jeff Salzman] of Vintage Volts who isn’t the author of the game. Honestly, the video doesn’t do the graphics any justice. It really is a great looking port that’s just as addictive as the Android/iDevice original.

The Raspberry Pi Compute Module


Raspberry Pi cluster computers are old hat by now, and much to our dismay, we’ve even seen Raspberry Pis crop up as the brains of a few ill-conceived Kickstarter projects. The Pi was never meant for these applications, with the very strange port layout and a bunch of headers most people don’t need. The Raspberry Pi foundation has a solution for the odd layout of the normal, consumer Pi:  The Raspberry Pi compute module, a Raspi and 4GB flash drive, sans connectors, on an industry standard DDR2 SODIMM module.

This isn’t something you can plug into your laptop (yet; that’s just a BIOS hack away, right?), but the new format does allow for some very interesting projects. All the normal Raspi I/O – CSI and DSI ports, USB, HDMI, JTAG – and a whole bunch more GPIO ports – are broken out onto an I/O board for development. The idea is that anyone can develop a product for the Raspberry Pi, create a custom board with a SODIMM connector, and use the compute module as the brains of their project.

The compute module should cost about $30/piece in quantity 100, available in June. No word yet on how much the I/O board will cost, but we expect a few open source expansion boards to crop up shortly so anyone can create a very cool cluster computer based on the compute module.


VCF East: [Vince Briel] Of Briel Computers


Judging from the consignment area of the Vintage Computer Festival this weekend, there is still a booming market for vintage computers and other ephemera from the dawn of the era of the home computer. Even more interesting are reimaginings of vintage computers using modern parts, as shown by [Vince Briel] and his amazing retrocomputer kits.

[Vince] was at VCF East this weekend showing off a few of his wares. By far the most impressive (read: the most blinkey lights) is his Altair 8800 kit that emulates the genesis of the microcomputer revolution, the Altair. There’s no vintage hardware inside, everything is emulated on an ATmega microcontroller. Still, it’s accurate enough for the discerning retrocomputer aficionado, and has VGA output, a keyboard port, and an SD card slot.

The Replica I is an extremely cut down version of the original Apple, using the original 6502 CPU and 6821 PIA. Everything else on the board is decidedly modern, with a serial to USB controller for input and a Parallax Propeller doing the video. Even with these modern chips, an expansion slot is still there, allowing a serial card or compact flash drive to be connected to the computer.

Video below, with [Vince] showing off all his wares, including his very cool Kim-1 replica.

VCF East: PetPix, Streaming Images To A Commodore PET


Thought the Vintage Computer Festival would just be really old computers with hundreds of people pecking 10 PRINT “HELLO” 20 GOTO 10? Yeah, there’s plenty of that, but also some very cool applications of new hardware. [Michael Hill] created PetPix, a video player for the Commodore PET and of course the C64.

PetPix takes any video file – or streaming video off a camera – and converts 8×8 pixel sections of each frame to PETSCII. All the processing is done on a Raspberry Pi and then sent over to the PET for surprisingly fluid video.

There is, of course, a video of PetPix available below. There are also a few more videos from [Michael] going over how PetPix works.

VCF East: The Swyft Card


Ninety five percent of the population will say Apple computers is the brainchild of [Steve Jobs]. The other five percent will be right, but what nearly no one knows is that the Macintosh project was originally conceived by [Jef Raskin]. He holds the honor of turning the Mac into an, ‘information appliance’ and being one of the first people to seriously consider how millions of people would interact with computers.

The Mac wasn’t [Jef]‘s first project at Apple, though. Before the Mac project he was working on something called Swyft – an easy to use command line system that was first implemented as a firmware card for the Apple IIe. [Mike Willegal] was kind enough to bring one of these Swyft cards to the Vintage Computer Fest this weekend, and did a demo of it for us.

The basic idea behind the Swyft card was to have an integrated word processor, calculator, and access to Applesoft Basic. Holding down a ‘leap’ key – in the case of the Apple IIe add-on, the open apple key – allowed the user to search for text and perform operations on any result. It’s odd, but it just makes sense in some strange way.

[Mike] is doing a build class at the VCF today where anyone attending can build their own Swyft card. He also has instructions for building your own, should you want to experiment with one of the ‘could have beens’ of user interface design.
