Solas is an RGB LED controller for the Amiga, it also has some other interesting functions. Solas connects to the Amiga on the clock port and can control two LED strips. Solas has also the ability to control fan speed and measure temps. It is also a clock port multiplier!

While I am not very interested in RGB lightning in computers typically, the killer application for using RGB lights in an Amiga is that the LEDs can react to noise, so you can play a module and see the LED strip react to the module playing. That is very interesting since I enjoy playing modules on the Amiga.

If you are interested in the Solas board I highly suggest visiting the official Amiga Solas website and ordering one now!

Building the Solas LED controller

I like building hardware myself so I asked if I could get the Solas as a kit, which I could. I also got a second Solas already built, it is a long story why and I wont write it down here to bore anyone. Lets just say, resistors can go bad sometimes and sometimes it can be good to have an oscilloscope in your toolbox (I dont have one).

Here is the Solas in kit form. A nice mix of through hole parts and surface mount components. Also note all the cables for the temp sensors and power cable.

The square space if for the chip that needs to be programmed. You can also see all through holes for pin headers and clock ports. The manual comes in really handy here in understanding how everything is tied together.

I thought I could program the Solas with my RPI. I have successfully managed to program many projects that uses Xilinx CPLDs with the RPI but was not successful in this case. So I got a cheap Pickit programmer. It is not visible in the image above though but worked fine – setting up the Pickit programmer with the correct software and settings was a nightmare though.

So here is the little PCB finally fully built and installed in the A1200. As it connects to the clock port it is very important that it is fitted correctly on the bottom pins. If you use a cable and mount it wrong way, expect card to break. Why would you mount it on a cable? Say you have an Amiga 1200 tower, it might be better to mount it on a cable so that a Zorro 2 or Mediator backplane can be fitted in the tower. Mounting Solas on a cable is also relevant if you have a clock port in a big box Amiga through a Zorro card.

Next steps, connecting all the cables to Solas and Amiga 1200

The manual is very good at explaining how you hook up all the cables, it is slightly confusing doing this without consulting the manual. In the image above, there is a small PCB that sits under the upper Kickstart chip and hooks up to the Solas with two wires. That is for activating the other clock ports on the Solas (IIRC).

How to connect sound output into Solas on a ReAmiga 1200?

Since I was using a ReAmiga 1200 and not a Commodore made Amiga 1200 there is one difference that needs to be taken care of. On a genuine Commodore Amiga 1200, you can pick up mono sound from the modulator. But the ReAmiga 1200 does not have a RF modulator and is missing the mono output there. On later ReAmiga 1200 (I have v 1.5) there is space for a pin header close to the keyboard MPU chip where you can pick up mono sound (see image above where I have soldered on one pin header to the motherboard). Also note the place above and to the right of the pin header where you have to add a 10uf ceramic capacitor. I have not added the capacitor on the picture above.

To get the Solas to react to sound input I also had to place a 10k resistor inline with the cable connected to the pin header and to the Solas board. After that, everything worked fine!

So here you can the full setup. Unfortunately it looks a bit messy with all the cables all over the place. It is possible to clean it up a bit, but for testing purposes this was fine. You can also see where I placed the RGB LED strip. I routed the cable from the Indivision MK3 under the Solas board, made it look much cleaner and works fine.

Closeup of where the RGB LED strip is mounted. Even though it is mounted upside down in a solid black case it works fine and you can clearly see the light the LEDs are emitting when they are lit.

SolasControl – Software to control Solas

Solas comes with a great MUI based program that lets you configure Solas. The way this works is that you configure Solas, then you save your settings to the Flash on the Solas. That means that Solas will work with software that fully takes control of the Amiga.

SolasControl is an easy to use program, in the image above I have configured Solas to show a solid green light when the Amiga 1200 is idle. It looks like this:

Solas styles and events

As you can see on the image of SolasControl, you can set the level of brightness for the LED and in the highest strength the LEDs are very bright. I usually do not run the LEDs at the highest brightness.

A static color is a bit boring. There are many styles you can chose from, my favorite is a rainbow scroll with a low brightness setting when idle. See the video below to see an example of it where I chosed blue and red as colors for the scroll.

Speed, colors, brightness and size depending on style chosed can be configured to ones preferences.

There are in total five types you can set the Solas to react to, Idle, Floppy access, HDD access, PCMCIA access and Audio. Idle just means when Solas is idle (when the other types are not active). Audio is when there is audio output and floppy/HDD and PCMCIA is when there are activity on these devices.

I like to run Star Trek Viewer for HDD Access, its a nice effect when accessing the HDD. I also as said before run Rainbow Scroll with a low brightness setting when idle. And finally, the pièce de résistance, audio. I like Level Meter (VU) for audio!

RGB LEDs reacting to Amiga sound

I want to point out that I usually run a little more fancy Workbench (even on this non GFX board AGA only Amiga 1200 WB 3.1), but in this case I toned it down a lot to clarify images.

In the image above I play a module in HippoPlayer, I have also configured Solas to show Level Meter when sound is playing. And I think it looks fabulous!

This is actually why I think the Solas is so exciting since I wanted a hardware device like this for the Amiga for a long time. I remember looking for similar types of hardware on AliExpress more than 15 years ago that could be added to a 5.25 bracket back when I had an Amiga 1200 tower. But this is so much better since it can be configured on the Amiga!

What about controlling fans and measuring temps with the Solas?

Solas comes with two sensors you can place where you want to. I placed one on my Indivision (as it runs very hot) and the other on Alice as it also runs hot. It is possible to add a cable between TerribleFire 1260 and Solas to measure 060 temps, but I have not had time to do that yet, but thats on the todo list.

The fan control function is very interesting particularly if using the Solas in a big box Amiga with many Zorro cards and hot CPUs. I think this is a nice alternative to CPLDIcy.

Usefulness of more than one clock port?

There are exciting developments in the Amiga hardware world where some users have created clock port based WIFI cards for the Amiga. There are sound cards for the clock port and USB cards. So having more than one clock port can actually be usefull – who knows what type of hardware will be released for it in the future. Having a couple extra feels great for the future.

Solas and big box Amiga computers

It is possible to add a clock port to a big box Amiga with Zorro slots through an old Buddha card, ZORRO-IDE-LAN-CP card and many other cards. That makes it possible to run Solas in an A2000, A3000 or A4000.

There is also this exciting ISA card that functions as a carrier for the Solas. As you probably already know, ISA slots in an Amiga are totally passive, meant to be used for PC bridgeboards or TBC cards. so the Solas ISA carrier only provides power to the Solas. It has some useful pin headers though.

Mounting the Solas to the ISA carrier board needs a slightly modified Solas card. One also needs to figure out how to connect sound to the Solas. I figured out that I can take it from pin headers on the ZZ9000 graphics card I am running in my Amiga 4000TX.

Keep in mind though if you have maxed out your Amiga expansion slots this sandwich can be difficult to fit as it takes up more height than a regular card.

Next steps!

I have not had time to install my second Solas in my A4000TX yet. But expect to see updates on this page once I have. I have my A4000TX mounted in a full tower with a mesh front and plan to run two LED strips on both sides of the front.

Final thoughs

As you can probably tell, I have only positive things to say about Solas. Highly recommended! I also think the Solas board is one of the greatest hardware developments for the Amiga in recent years together with PiStorm and open hardware such as BFG and TF series of cards. Great work everybody 👍
