Upgrade kit for the A3640 (2 wait states removed)

[cadillac46]

My friend, whom I bought this kit wrote to me, that this kit won't work in his A3640.
Another friend have a problem with ROMY 4000. It won't work too. Both bought from Cosmos.

Amiga won't boot with ROMY installed, just black screen. The same with A3640 (rev.3.1). My friend had changed some e-mails with Cosmos, but one day Cosmos stopped to answer.

Hum, I reply to all emails...

I sold about 80 Romy, and you are the only one to have issue...

Are you sure your building rom is correct ?

Here a good howto : http://www.mfilos.com/2010/12/guide-create-and-burn-custom-kickstart.html

EDIT: With Custom ROM 3.9 from you, Amiga has yellow screen. When he's using original 3.1 ROM it works fine. So, Romy is working.

But there is still problem with A3640 - 2 wait states mod. I only know that his card A3640 does not work with your modification. But it works when you insert the old chips. Maybe your chips are incorrectly marked or badly programmed?

Maybe some deflashing during shipping...

I always put some antstatic bags around Romy and the ICs... Don't know if it's enough...

When I flash all ICs, all the time, I "verify" three or four time each IC with my programmator...

Anyway and again, I always answer on all emails : with these problems, I'm ok to flash them another time... Just send me back the ICs and only the Gal plugged on Romy...

OK. I'll tell him to send back IC's.
