I have a new in box Commodore Amiga 1000 Prototype

NTSC A1000's had the daughterboard, PAL ones didn't.

Yeah, I think you are right. My A1000 (ntsc) had a daughter board.


So is this one PAL or missing the daughterboard,  or could it possibly be a rare NTSC version w/out daughter board?


These are great pictures btw.  Thanks for the quality and quantity.  Super awesome find.

Seems odd that you would need a board just to work in the computers native country.

Yeah, you wouldn't know.  It's hard to know every model let alone what they all look like inside.

I don't know for sure, but I think the large daughter board was eventually shrunk down to the be the "Gary" chip later on.  The PAL machines came out later than the NTSC and probably had Gary in them by then.  I believe later models of the A1000 (ntsc) no longer had the daughter board either, but a Gary chip as well.

So A1000s came out before Gary existed I believe, that is why it is sort of odd this has no daughterboard.

I could be wrong but I believe that particular chip wasn't ready so they had to use lots of programmable ones. By the time the PAL one came out they'd had time to mask the custom chip properly.

Nice fine, though! And for goodness sake don't modify it unless you know exactly what you're doing....!

I think it is the same with EHB mode.  Early NTSC 1000s didn't have EHB mode.  Later NTSC A1000s had EHB and all PAL A1000 had EHB.  

Anyone know when the first PAL A1000s were released?

No! Put that soldering iron DOWN!

Just unsolder all the pieces and sell them separately.  :-)
