Rarest of the rare: The Commodore Amiga CD1200

The arrival of CD-technology for personal computers caused a huge shift in software development and user experience. The added storage capacity led to a hugely increased amount of content delivered with a software title. Gone were the days of swapping floppy disks, now a single CD could deliver everything required, and much more. CD was everything and everywhere.

Commodore's CDTV, with a built-in CD-ROM drive, was an early attempt, but the underlying original Amiga hardware wouldn't benefit too much from a CD drive, and there was simply not much experience in how to make good use of the CD's extra capabilities. But after the PC and Apple Macintosh market had established the technology and created a demand for added content, it became a must for the Amiga, too. The only Amiga model to make full use of CD-technology is the CD32 console, booting from CD without any additional setup, playing back full motion video and integrating the Amiga's audio with the CD's 16-bit audio tracks.

Wait. The only Amiga model? No. In fact there was another Amiga model that could do the same things, of which nine units were built, and only one is known to still exist today. It's probably the rarest of all (near) market-ready Commodore Amiga developments. It's the legend, the one that should have boosted sales to new heights, potentially saving Commodore from bankruptcy.

It's the Commodore Amiga CD1200.

Just to avoid confusion, we're talking about the "Commodore Amiga CD1200" - not the "Commodore CD 1200 Controller" for the CDTV, or the "Alfa Data CD1200" PCMCIA controller for the Amiga 1200.

It's a CD-ROM drive to be connected to an Amiga 1200, and with a little extra. It has a custom "Data Input" connector, that connects to an expansion board in the Amiga 1200's internal expansion port via cabling routed through the Amiga 1200's backside blanking plate. It also routes Amiga audio signals through, merging them with CD-audio. The expansion board adds a FastRAM SIMM slot, and - in a proposed later model - would have had another custom chip, and room for a 68030 CPU upgrade.

The CD1200 was presented to the public at the CeBIT 1994 show in Han(n)over, Germany. It's goal was to unite and boost Amiga CD32 and Amiga 1200 hardware and software sales, by being compatible with the former, and adding a CD drive to the latter.

You can read about the CD1200 in Amiga Format's first-hand post-CeBIT report:

Now what makes the CD1200 such a rare piece? Well, first of all, according to Beth Richard, lead engineer on the project, only nine prototype units were built.

Eight of them got lost in the turmoil of Commodore's bankruptcy, and only one unit resurfaced. And even that one wasn't instantly recognized as the rarity it is.

Listen to Andy Spencer from the Retro Computer Museum Leicester retell the story of discovering the unique CD1200 in a dusty barn (video by The Centre for Computing History):

But the true recognition of the CD1200 came after Ravi Abbot had been visiting the Retro Computer Museum Leicester, and published his video about it in November 2016:

Established YouTuber Dan "" Wood has picked up the subject, and had a more in-depth talk with Andy, and Ex-Commodore UK's David Pleasance. His video of December 2017 covers the unsuccessful search for other CD1200 units still in existence, the rediscovered CD1200's relocation from the back of the museum to a more prominent place, and lots of details from Andy and David:

Would the CD1200 have been able to save Commodore? Well, maybe. In 1994 Sony scored a huge hit with it's Playstation console, which has a CD drive, but also offers hardware 3D acceleration and 16-bit 24-channel sound. A CD-drive had become a must-have, but chipset development and platform architecture had also been moving forward rapidly. A CD32, or CD1200-equipped Amiga 1200, wouldn't have been able to compete with PC and console development for a long time, but maybe CD1200 sales, and now-CD32-compatible Amiga 1200 hardware and software sales would've bought Commodore enough time to release the next generation of CD1200 with CPU upgrade, and so on. But it's just speculation.

For Amiga 1200 users it would have been a fantastic addition, with a 68030 CPU on board, especially due to the beautiful design that matches the Amiga 1200 one's. And Amiga CD32 owners would certainly envy the added horsepower, memory, keyboard and i/o-ports.

From todays point of view it would of course just be great to have such a device, in whatever condition or configuration, because it's sooo Commodore Amiga. The fact that there's presumably only this particular one in existence, a rare piece from the last days of Commodore, makes it pretty much the collector's item par excellence. Time will show if maybe another CD1200 exists - maybe it resurfaces due to the raised interest created by discovering and exposing this one.

Until then, all we can do is visit the Retro Computer Museum Leicester and feast our eyes on the one that's there.

All we can do? Amigans weren't Amigans if they weren't willing to do something about that. Yes, there is some minor activity going on: A facebook group is dedicated to resurrecting the CD1200.

In the video by The Centre for Computing History (see above), Andy Spencer says he'd like to open up his CD1200 one day, and maybe, together with the pictures published in magazines, and knowhow from people involved with the project, this will give the insight required to recreate the CD1200 and it's expansion board.

Nothing has materialized yet, but who knows, they also said Doom can't be done on the Amiga...

For your nostalgia-needs, here's another video presenting the CD1200 - note the fake Amiga 1200 case with a built-in CD1200, which is impossible due to CD size, but an intriguing idea:

Some magazine reports about the Commodore Amiga CD1200:

CU Amiga, issue 128, May 1994

CU Amiga, issue 054, August 1994

Amiga Format, issue 59, May 1994

Amiga Format, issue 66, December 1994

Building the TerribleFire TF530 accelerator board, part 5: Testing. More testing. And... happiness.

I'm learning new things about the TF530 almost daily...

Documentation is a problem when trying to build these accelerators: there's no place where you can quickly look up how to do something. Instead you have to dig through Stephen Leary's hour-long videos on YouTube, or a single endless thread on English Amiga Board, or ask in forums. Which is not a bad thing, but it's very inconvenient if you want to make progress. That's why I created some sort of "user manual" for the TerribleFire boards:

Anyway, what's happened since part 4 of this series?

Full setup with CF-adaptor and -card
Things were actually looking pretty good. I've been using a 24Mhz oscillator to build the board, and the original firmware (from a "rev. 2 final" GitHub checkout). But I wanted to rev up the board a little... Other people are using clockrates of 36, 40, or 50 Mhz. And then there are a couple of new revisions of the firmware. And in one or the other way these have to match. I've tried a 40MHz oscillator, and two other (apart from the original) versions of the firmware. Then there's the IDE controller. Simply plugging in an IDE cable - without any device attached! - changes the A500's behaviour in combination with the 40MHz oscillator. Exchanging the 1.3 Kickstart ROM for a 3.1 one made a difference once again. Lots of testing, and lots of glitches, and more testing, and more glitches: mousepointer uncontrollable, random crashes, boot picture gone, ...

It seems that the 33Mhz 68030 doesn't like overclocking very much - but with a 32MHz oscillator (33Mhz oscillators seem to be rare), it now runs stable! I expect a few more issues - like checking RAM soldering points - but for now I declare it "working fine". It boots quickly from the 512MB CompactFlash card attached, and with the additional 2MB of RAM on the TF530 and the new 3.1 Kickstart ROM the A500 is now an up-to-date, very usable Amiga!

Yesss! I am __very__ happy with it. :-)

SysInfo speed test with the 32MHz oscillator installed
Nice to have: an LED on the CF-card-adaptor

An "in progress" conclusion

From a personal perspective, I can say that I've learned a lot. I mean: A LOT. Stephen Leary's videos give a huge amount of information, and by building the accelerator I've expanded my set of tools, improved my soldering skills, and gained some knowledge about the parts used. Overall, for me it's a huge step forward in understanding the inner workings of Amiga computers, the TF530, and electronics in general.

And of course the Amiga 500 got a huge update, it's a completely different machine now. For a very reasonable (money-wise) price.

So the whole process is a massive success for me. :-)

No outside signs of the changes on the inside... :-)

Still, there are a few things to keep in mind about the TF530 accelerator and the build process: First of all it takes an insane amount of time to build, if you don't know what you're doing beforehand. I certainly didn't. There was a lot of research involved, on all levels. Secondly, the TF530 is clearly not an industrial-grade product: it's an "in progress" project, a moving target. You have several options when it comes to CPU and oscillator, and these have some interdependence with the firmware releases, which are still going on. The physical layout of the TF530 isn't perfect, you (may) need a relocator board to fit it into your Amiga, you (may) need to use specific connectors, and still it fits only barely between the Amigas other components and casing. For example, adding a Kickstart-switch may turn out to be quite difficult now with the TF530 in place.

But all these quirks don't change a simple fact:

It's effin' great! 

Thank you, Mr. Stephen Leary!

Thank you very, very much for sharing,
and lighting up the fire - the TerribleFire!

So far, so good. I currently consider this to be the last entry in my little series about building the TerribleFire 530 accelerator board. But who knows. And there's so much more to do... maybe a TF328?

Demoscene: Nerve Axis on TV in 1998 / "Relic" live

Now this has to be a unique, and one of the rarest pieces of Amiga history ever: demo group "Nerve Axis" gets visited by TV channel ".tv" ("dot TV")!

This took place in 1998, after they had released they had won the Assembly 1997 demo competition with "Pulse" demo, and were working on the successor called "Relic".

This is probably the only time in history a TV team visits an Amiga demo group at home, at work.

(Are you aware of any other such occasion? Please leave a comment below!)

Today of course we all know that "Relic" went on to win the Assembly 1998, and became a legend in it's own right. It's a demo of biblical proportions, and it's destruction sequence is unparalleled to this day.

Thanks to YouTube we can relive the moment this got presented to the public:

For perfect quality it's of course best watched live on your AGA Amiga. :-)

But if you don't have one handy right now, and you don't mind Amiga-emulation (WinUAE), here's another hi-quality version:

Huuuuge respect and thanks to Nerve Axis for their amaaaazing work!
