| In these days that many exhalted people wave at a porting of Amiga on infamous tiny RasPi underpowered card-sized ARM PC (that despite of its poor features and aimed only at hobby market is very cheap and sure dozillions times more performant than a Classic Amiga) how is it possible that none proposed a Raspberry clone on Zorro III card in order to use it as a peripheral, and sort of Bridgeboard for Amiga?

My my, what a wonderful idea. It could also be done using the xorro slot on the X1000 and the X5000. It would even bring commonality between classic and NG.
Yes, there would be technical difficulties, but thats the fun of computing. :)
In fact, the only reason I have no desire to purchase a X5000 is lack of a proper xorro protoboard for either of A-eons' big boards. Difficult for me to understand, but it is what it is.
There has been mention of a BeagleBoard on a card on AW, but such discussions usually disintegrate down to 'AHHH! You're going to blow up your computer. Better to do nothing with it and keep it as a future antique.'
Not sorry for the rant. This post may be deleted.
Please continue.

Yes, that is my plan.
There are many ways to configure such a card, for example one can make use of the raspberry pi compute modules and just ad sockets for them, or one can have mounting space for Pi Zero, or "full size" pi, and pin headers to connect them. Last edited by kolla on 05-Apr-2017 at 02:23 PM.

What pins on the "pi" stuff will connect to the Zorro connector?
The best option I've seen is to use an undocumented parallel data bus with 16 data bits, and if I remember and understood correctly, only 6 address bits. I have yet to be convinced there is a reasonable connection pathway to be useful. _________________ All glory to the Hypnotoad! |

No. I have one of those. It is a strip board and it is CRAP for doing projects.
There is a 1.1 version, but I have no idea if it is the same. Amiga-on-the-Lake was supposed to answer that question but so far nothing.

The best connection would be over the data buses, well ZorroIII is complicated, you should calculate the costs of a cheap ZIII boards at least, but the MCU on the RasPI doesn't offer a CPU bus .. so what to do.
Using parallel I/O, SPI, Ethernet or USB ?
It depends on things you what to do with such a board.
Using it as a GFX card could be possible with a fast connection, but you want have any benefits against normal GFX cards ...
Using it as an I/O expander might be possible over USB or Ethernet, but the Amiga and its ZIII expansion would just add costs and problem to the RasPI.
Binding both systems together seems like a bad idea to me ... and ZIII makes everything more expensive. Last edited by OneTimer1 on 05-Apr-2017 at 08:30 PM.

| Well, my idea is a "pi cluster" on a board, reachable from Amiga over ethernet. So it can just as well sit in an ISA slot, it's just for getting power. _________________ B5D6A1D019D5D45BCC56F4782AC220D8B3E2A6CC |

I just had the idea by chance. I dunno if feasable or not and I am not a technician who could give a tech opinion on about connecting a Raspberry to Amiga thru its i/o pins.
As Raspberry Pi Zorro expansion I intended if it could be built a zorro card populated with Raspberry Pi circuitry, with data chip and bus transferring hardware connecting DMA with Amiga.Last edited by Raffaele on 05-Apr-2017 at 11:39 PM.
