Question The quest for the unknown connectors...

Well now I've finally got all the information needed to complete the A1200 motherboard map, thanks to Severin and adolescent for the missing information.

The final version of the A1200 Motherboard Map is in the zone now if you want to take a look at it.

I'm wondering what the four chips to the right of the PCMCIA connector are? They're probably just the controllers for the PCMCIA device. Maybe.

Now about those mysterious unknown connectors. On the A1200 motherboard you can clearly see the IDE hard drive connector to the left of the Lisa chip. You can also see the Amiga's floppy drive connector above the CIA chip to the right. As you can see from this zoomed in picture there are two other strange connectors either side of the RAM chips. Anyone know what these are for? Are they for adding a small fast RAM board that bridges over the RAM chips?

The bottom one is the Clockport connector, in is where those fast serial devices (Hypercom) and other cards connect.

As for the top ones?

Also by the ram is:

U9/BT9 - for a clock chip and battery

bottom left of the board are TP1 TP2 & TP3, iirc they were for terminating resistor packs...
