Hi,

does anyone have the Operating System chip (U6) from an XF551 disk drive for sale, mine has died big style.

Cheers
 
Are you sure it is the ROM? XF's are notoriously poorly built. A lot of problems cone from dry solder joints on the SIO connector.
Also if you have or know someone with an EPROM programmer you can update the OS to HyperXF etc
 
Hi Mimo,

it is the OS chip. Looks like the drive has been stored in a damp enviroment. Seven of the legs have rusted through, with corrosion showing in the chip carrier. I have replaced that, and checked for dry joints on the PCB. So I definitely need th OS chip.

Regards
