This is a good buy.
Several ppl was asking just 1-2 weeks ago for 14MB ram upgrade.

And I can vouch for the seller - I've bought from him once before - dead on
accurate in his description and fast service.

Hi.
Got the 14mb board Ok, but have a problem.
Put the board in and Falcon will not boot.
Have tried cleaning simm contacts and different jumper positions, but still same.
Put the 4mb board back in and all works Ok.
All I have to do is plug in the board, or is there something else to do ?
Theres not a lot to go wrong, maybe try another simm, any ideas ?
Cheers

They need a particular type of SIMM. The 16Mbyte SIMM MUST be made up of 8 chips of 4Mx4 and not 2Mx8

Fit a SIMM with 2Mx8 chips and it won't boot.

I had the same problem with DJBase's Atlantis. I had perhaps 20+ 16Mbyte SIMMs of various makes and only one had 4Mx4 chips

The SIMM in the photo has 8 * 4Mx4 chips

wow... never knew the issue.
My other Falcon had a similar looking memory adapter with 16MB ram. Came with it when I purchased the Falcon.

I posted about it a few times but got "that's rubbish" from Simbo (who was selling 16MB SIMMS at the time) but I've got enough empirical evidence that this is true.

[Jammer]

Not sure what to do next.
Anyone willing to lend me a simm to see if it works ?
Thanks

No comment.

If you were based in England then send me a PM with your address and I'll "loan" you my working 16Mbyte SIMM

Have you tried changing the jumper? In the photo above it looks like it is set to the (correct) 14MB setting though

[Athlord]

Hello,
i am sorry about that.
why do you not report to me via pm?
Cheers
