A2000 problems with RAM card

[dougal]

9/10 Times my A2000 will not boot if the RAM card is plugged in.

Instead it will either give a RED screen or Green screen or Blue screen or horizontal lines in different colors. Sometimes it will boot and work perfectly addressing the ram and all.

Works all the time without the card.

The specs are A2000 with Rev 4 motherboard, Kickstart 2 and 512 Ram & an A500 floppy drive. The ram card is a Commodore A2058 with i believe 2MB Ram.

Any idea whats wrong?

NOTE: Sometimes (without the ram card) it will boot to a Software Failiure and i will have to press LMB
NOTE 2: If the card is not inserted fully in the zorro slot (i.e not pressed down hard) it seems to work.

Assuming all the RAM chips are good and jumpers are appropriately set, ensure the edge connector is real clean on that board. Same with the female Zorro on the Amiga itself. Failing that, sound like your power supply might be getting weak. Time to replace the caps maybe?

I tried 2 power supplies so i guess it must be the card.

The card looks clean on the edge connector and i tried 3 different zorro slots on the Amiga.

I must note that the Amiga when i bought it was in a terrible state hence it only costed me 35 euros. It was in pieces.

What could i check on the card and amiga?

Or a leaking battery.

I had removed the battery before it leaked.
