Hi ,
I am on the waiting list for V1200 and just about to send my motherboard ( Rev 1.D.4 ) off to AmigaKit to get its caps replaced.

I wanted to know if i need to ask them to do timing fixes as well ?
I have no idea if my board requires it

Thanks

Nick

I own a 1d4 as a spare motherboard (without timing fix), I remember that I once successfully booted with it into coffin os, but no further tests have been made.
 
  If you want me to do anything specific, I can do it for you

Hi,
I checked the V1200 on three versions of the 1B, 1D4 and 2B boards.
It works stably on all of them, I didn't do a timingfix. Originally they have E123C, E125C capacitors installed. No E121C, E122C capacitors. Now I'm using an amiga with a 1D4 board and it's super stable.

Same here, just tested my 1d4 did few benchmarks, demos etc and i could not notice any difference from the 1d1 revision

Brilliant thats what i needed to hear!

Ill just get it sent off for a recap then!

To be honest none of the caps look dodgy but I rather be safe than sorry!

I have tested on 1B, 2B, and 1D4 boards, all just recapped, all with timing fixes. the V1200 hasn't crashed once on any of them.

Thatís the right thing to do, sometimes you canít tell they look ok but the V1200 will push the computer to the limit.
