with its 'small' ARM processor runs the OS and programs, and the 
'massive''Vision' (hence I think, graphics centered) one is just 
idling(actually kickstarting the ARM core at boot time only)  ?


My recollection is that the processors in the RPi are both ARM variants, 
although the one dedicated to graphics has got a lot of extra stuff 
bolted on. What the RPi is doing is an interesting alternative to e.g. 
writing a loader in Verilog to run in an FPGA, with the objective of 
having no ROM-based loader intruding on the address space. It's now at 
least semi-open, and I think I've read of interesting stuff being done 
with it.


The DSPs in the BB's OMAP chip are general purpose (i.e. rather than 
relying on bolted-on special hardware) and are fast enough to do things 
like emulating an MFM disc drive in real time (i.e. as a drop-in 
replacement for obsolete hardware) or a 100MHz logic analyser

Didn't first (single-core) series of RasPI had similar 'theme' ?

with its 'small' ARM processor runs the OS and programs, and the 'massive'
'Vision' (hence I think, graphics centered) one is just idling
(actually kickstarting the ARM core at boot time only)  ?

good for high-speed stuff. However unlike the main processor I believe
these have to be programmed in assembler.


I believe the two I/O processors are Cortex M0 and can be programmed in
just about anything, probably even FPC with a little work.  Nice in that
realtime tasks can be handled with dedicated CPUs while user interfaces can
be done in non realtime code.

There are also more open source based ones like BeagleBone.
There is also the $9 "chip" computer
Not sure if these count as altoids, never heard that before :-)


American brand :-)

Beagle bone is more expensive, but more open sourced


Particularly notable due to a couple of DSP-like processors which make 
it good for high-speed stuff. However unlike the main processor I 
believe these have to be programmed in assembler.

No, all the RPi 1Bs had 512MB (except for the very early ones), as well as the 
B+
RPi2 and 3 had 1GB.

Paul, this is very usefull information. Thank you.

There are five similar "Altoids tin-sized" single board processors I'm 
aware of.
The Raspberry Pi , The Orange Pi, The Banana Pi, The ODROID, and the 
ASUS Tinkerboard. The Tinkerboard is sometimes referred to as the 
Maker Board.


Processor:
All of the Orange Pis, All The Banana Pis, The ODROID C1, The 
Raspberry Pi 2B use a Cortex A7 processor.
The Raspberry Pi zero uses an ARM1132F-S (Don't even ask me how they 
can sell a computer for $5 retail!)

The Raspberry Pi 3B and the ODROID C2 use a Cortex A53.
The ODROID XU4 uses a Cortex A15/A7
The Tinkerboard uses a Cortex A17

Cores:
The Raspberry Pi Zero is a single core.
All the others are quad core.

Memory ranges from 500 meg to 2GB depending on model.

Instruction Set:
The Raspberry Pi Zero uses an ARM V6 instruction set.
Raspberry Pi 2b, 3b; Banana Pi M2, M3; Orange Pi One, PC, Plus, Plus 
2; ODROID C1 Plus, XU4 all use the ARM V7 instruction set.

The Raspberry Pi 3B and the ODROID C2 use the ARM V8 Instruction set.
I could not get a solid answer for the Tinkerboard but some people 
believe it's an ARM v7 instruction set.


In theory any of these that use the ARM V7 instruction set should be 
equivalent to the Raspberry Pi 2B and in theory if they have a Linux 
operating system with the same modules it requires then the version of 
Lazarus/Free Pascal for Raspberry Pi should work on them. The 
operating words here are "in theory." There can be subtle differences 
in the associated hardware on the board beyond the processor. Probably 
you just have to try running apt-get or whichever installer it 
supports for the version of Linux it uses and find out.


I've ordered a Tinkerboard myself to play around with. Amazon says 
it's been delayed until April.
