Help - my ram dkb1202 for 1200 passed away!

Hiyas Tiago,

If the DKB card has no memory on it does the A1200 boot with it installed?

have you tried another memory SIMM ?

Recent testing with a Hawk accelerator and a lot of 72 pin edo rams (i have 12 modules ranging from 4mb to 16mb), the result of a bad ram module is a black screen with nothing appening (i have experienced this with some 16mb 60ns that i've tested), so you maybe lucky enough and is just the ram module that is damaged. ( don't know why but all 4mb edo rams work... LOL)

I did try with no simm on the card and with jumper setting to "no ram" and it didnt work.
Tomorrow i will try other simm module, i have other 10 simm modules from other old pcs.

I testes yesterday in a second A1200 and with other 5 memory modules, the card is dead.
I must get a new one, and now that i have a tower project i will try a 030.

@Tiago

if you want my friend, I can have a look at it for you. Its possible one of the PAL chips has failed, if so I MAY be able to repair it for you.

[Tiago]

Will you do that for me?
I could send it to you, i send you the money to send it back (post), and some extra cash for the work.

@Tiago

dont worry about the work, I offer it free my friend, I will say that I cannot guarantee that I can fix it, but I will certainly have a look, PAL chips and traces I can repair, but shoud there be a fault that is out of side of my ability to fix then i shall send it back to you (i wont butcher the card).

With a little luck its likely to be a replacement chip
