Amiga 2000 Motherboard resistor packs
« on: June 15, 2021, 08:11:06 AM »
Hi all,

Can any one help me identify what the resistor packs are on a B2000 V4.3 motherboard? Specifically the one at RP900 next to the CPU socket. See pic.

And where can I get new ones as I need to replace at least one of them.

Thanks in advance.

Perfect. Thanks for the links.

After checking continuity and finding no broken traces I decided to pull Agnus from the socket. I don't have a chip puller so to avoid damaging the socket I managed to push the chip out by gently pushing a rod in the holes underneath the socket. A thorough clean with isopropyl alcohol of the socket and the chip. Reseated Agnus. Powered on an bingo I get the insert floppy boot screen! machines has function for more than 5 years and now its up and running. Installed GVP hard card with SCSI drive, CD ROM, Gotek, Picasso II, Flicker fixer and CSA Magnum 40/4 040 CPU board.

All working except the CSA SCSI. No autoboot hence why I have the GVP card installed which works fine.

Best.
