The latest chip date code I can see in that pic is 8445 (on the 74HC112 to the left and slightly below the Portia chip). So at the earliest, that unit was made in late 1984.

The pic here shows the Portia chip (later known as Paula) at the bottom centre. "4703" is written on it. That chip looks to be on some kind of "kludge board", that board plugging into the socket on the motherboard. That may obscure another of the custom chips which could be plugged directly into the motherboard. Another board with what looks like the mouse port connectors on (lower right of the above pic) could obscure another custom chip.

The serial number label on the side says
COMMODORE-AMIGA
DEVELOPMENT SYSTEM
SERIAL NO. D-116
Yes, you're right! I'm going blind

I did some searching on Lorraine and found this page...

That explains it then and that the picture of the breadboards/developer system were some kind of showcase to show what they had developed (not physical linked to one another).. ah, makes sense now.

edit: that photo of the breadboard/developer system were taken in 2003 - Dale Luck owns those apparently.
