This is the REAL Amiga

Never forget it ;D

Uhmmm... which one?

It's the Amiga before it became the 1000!

The lorraine (The name the Amiga company gave it before they were bought by CBM!)

Indeed, my friend bippy.

That's all ONE computer shoonay, each of the stacks of vertical "motherboards" are the original logic arrays of each of the custom chips. So each mass of 4/5 mobos became one chip later.

For example, I think the crap on the left is Agnus.

Next time you think "Amiga", think of this picture, and not that A1 bollox ;D

OH MY

Thanks Akira!

I never knew there was something "before Amiga1000"

...talk about custom chips

Nice! Is there some more info on this?

all that it matters is that nice red display in the black box, wich you cant see in amiga keyboards.

This is the entire Amiga chipset created from what is called 74LS gate chips. Which just shows that the Amiga was what is called a "Gate Level" design. Multiple boards represent each custom chip in the Amiga.

Today chips are designed in HDL (Hardware Description Language) a sort of ultra parallel 'C' language, and then Synthesised into NOT AND OR gates.

Back then all the logic was created with hand built gates.... very time consuming... very challenging compared to today... but at the same time very optimal.

In order to get Commodore (or Atari?) to invest in expensive full custom silicon chips they had to prove the theory behind the hardware. Today we might use FPGA's or CPLD's (programmable chips) but then you had to wire-wrap / solder these logic DIP package chips together.

CORRECTION

Perhaps I was being a little TOO low level. The chips are not basic 74LS series gates (well not all of them) but the fore-runners of todays FPGA's.
