Title: Help! A1200 revisions...
Post by: Legerdemain on April 07, 2004, 02:50:32 PM
Hello!

I'm merely curious, since I am about to sell of one of my A1200:s to a friend I'm interested in knowing which different revisions are said to be a probable cause of trouble when starting to expand the A1200.

One of them is rev. 1D4, the roms (3.0) are put inside a socket (which is put on the socket on the motherboard) since they have some crossed legs. The connector to the mouseport on the motherboards is a male (the port on the back is connected via a flat cable and only consist of the actual port).

The other one is rev. 2B, the roms are put directly into the socket on the motherboard with no legs crossed. The connector to the mouseport on the motherboard is a female (the port on the back is connected via another card which seems just like an extension of the motherboard).

Which revision is the one I should keep, considering I am in the midst of towering up my AMiGA, adding Mediator and such?

Would appreciate any kind of answers or suggestions to this.

A good place to look would be www.amiga-hardware.com , they have a list of the mobo revisions and the timing fixes required for use with certain accelerators.

Im lucky Ive had a A1200 for long time and have a 1A revision  :banana:

Mines a 1D4 - Running an apollo 040/28, towered, no problems at all.

But some say it has timing issues... never come across any.

Keep them both! I doubt you have got much more than 1000 hours left between them, and when one dies you'll be happy to have a spare.

@Bloodline
That's an extremely depressing prediction you made! That's only 21 days each.
