This is an updated version that also cover A314 v1.2 Original post published 22 Februari 2020 - 23:09
In this tutorial I will use an A500+ rev. 8a motherboard with WorkBench 2.1 as reference. I will try to make it mostly a bullet to bullet post, to keep it as short and clear as possible
Setting up your hardware.
First thing to do is to make sure your computer sees the extra memory that A314 will share with your Amiga, and make sure that the RTC gets detected. The amount of extra memory you will retrieve from the A314 depends on your motherboard revision, and jumper settings.
Below you can the most common A314 setups without any motherboard modifications made:
JMPB3 / RAS0
JMPB3 / RAS1
With these setups for rev. 5, and rev. 6a you will NOT be able to use the PiAudio, RemoterWB or the VideoPlayer - these features requires shared chip ram. A note for those of you that happen to have rev. 3, set the A314 jumpers in the same way as for rev. 5. However, as far as I know there is no way to get chip instead of slow/ranger RAM.
The OpenKickstartSwitcher in combination with the OpenAmigaMouseTrigger makes a great enhancement for your A500/+. These fantastic little pieces of hardware - made by SukkoPera - in combination with a 27C160 EPROM makes it possible to switch between 2-4 different KickStart (KS) images. If you add a second trigger source, you could switch between 2-6 KS images. The maximum numbers of images you can use in you switcher depends on what EPROM you use:
One amazing feature of the A314 - the trapdoor expansion with a Raspberry Pi co-processor for A500/+ - is the Remote Desktop, or Remote WorkBench (RemoteWB), as it's called on the Amiga.
Although the RemoteWB has some limitations, I think it is quite useful in some cases. For instance, if you write a blog post and need a screenshot of your WorkBench (WB), it is very nice to capture the Amiga screen from your PC with relative ease. In my opinion, this is probably the closest thing to a "native" capture of your Amiga WB you will get, without too much hustle that is. Of course, you could always use UAE if you want to capture a screenshot or grab a video of your favorite game - but that would be cheating, wouldn't it! 🙂
For the RemoteWB to work, you will - as you have probably guessed - need an A314 expansion card with a Raspberry Pi. You also need to have at least 512 KB of shared chip ram between the A314 and the Amiga. Continue reading →
Have you ever wanted to get stuff from Aminet to your A500 in a convenient way?
- With the A314 you can, and here's my how-to-guide:
Above you can see when I use Midnight Commander (MC) from AmigaShell.
I run MC with two arguments: -a, --stickchars Disable usage of graphic characters for line drawing. -b, --nocolor Forces black and white display.
This is to make it look a bit better in AmigaShell. Continue reading →
Being kind of a newbie regarding linux, it was quite hard for me to pull this of. However, with a little help from my friend, who gave me the right tools to work with, I finally got this mojo working! This is the story of how I managed to get Spotify to play on my Amiga 🙂
I got the idea after I played an mp3 via my A314 - a trapdoor expansion with a Raspberry Pi as co-processor. The PiAudio-service is piping the audio via an Advanced Linux Sound Architecture (ALSA) plug called amiga. This plug pipes the raw audio via the memory that the Raspberry Pi and the Amiga shares. On the Amiga side the piped audio goes to the sound chip Paula, that takes care of the playback. Note that the Raspberry Pi takes care of the decoding. Continue reading →
Recently I bought an Amiga Optical Scroll Mouse from AmigaKit, and I also ordered the recommended adapter for my A600. However, I was not very pleased with this solution because it looked kind of ugly!
Amiga Optical Scroll Mouse with ugly adapter.
I decided to modify the connector housing by cutting away the plastic tabs that hold the connector in place. Continue reading →
I have finally managed to program an ATtiny85 to act as a RC switch! The switch will work as a "poor-man's-ESC-reverse". I bought a cheap ESC for my Ballbot Project and it has no reverse mode, it is made for RC aeroplanes, so I have to implement a relay that acts as a "polarity-switch" to be able to make a reveres motion on the motors.
