Weird A3000 memory problems

[cv643d]

Hello

I have an A3000 that came with a strange zip to 72 pin memory adapter, it didnt work, as was discussed in a previous thread here. I bought a new 72 pin adapter that worked on the sellers A3000 and it didnt work either when I tried it on mine (with his working 8 mb x 2 Simm sticks of memory)! showing 0 fast mem in Workbench. I am 100% shure I mounted booth of the adapters the right way.

I dont know where to go from now, any A3000 gurus here who can help me out on this one, can it be a jumper issue?

The only thing I did to the computer was I desoldered the battery because it started to eat on the motherboard (its running with no battery now). It was jumpered as an NTSC machine when I got it, which is strange since Im in Sweden where we use the PAL format. The previous user I think didnt have a lot of Amiga knowledge judging from the harddrive contents and layout, maybe he switched jumpers? (I have no possibility to get in contact with him).

Another strange thing is the chip memory only shows up as 1,5 mb even though I the memory sockets are full on the zorro side of the motherboard. But I dont think the kickstart is copied to the ram...  Shouldnt I be getting 2 mb of chipram?

/Thanks for watching.

Yeah...  I really need help with this.

Hello, thanks for the input.

Avail gives me maximum 2 mb, and 1.5 used memory. It must be the softboot  rom you described. I wonder since I have Escom 3.1 roms, if it is built in the roms that it will softboot the rom?

I cant get any 1.3 - 2.0 boot screen but thats maybe normal when you are running with 3.1 roms.

I tried every possible setting on the jumpers from the A3000 page on the Amiga Hardware site above but no go.

I think I need to track down a turboboard to see if it will work. And I'm gonna check out that A3000 site.
