Decided to dig out and clean up the Colt this weekend. In great condition aside from the dust. Never seen onboard video, floppy and hard disk controllers on an XT, quite unique. Had a nasty 3.6v battery which had leaked a tiny bit. Anyway everything off to the sink for a scrub up and swift desoldering of the battery. Floppy heads were pretty dirty and the drives made all sorts of grinding noises when in operation, so rails were clean and lubricated. Threw in a coprocessor just to see if it worked, it did! Unfortunately the hard drive was a bit cranky, making noises similar to the floppies before they were lubricated. Drive would read a bit then grind a bit then error out. Looked like the stepper motor was seized up. Put a but of oil on the outside bearing, didn't work so thought I'd take it off and do both sides. Whilst that in fact did do the job, unfortunately a washer was somehow left loose inside the case, it worked for all of 30 seconds before I picked it up to move it and the washer made it's way into the moving parts and.... well let's just say it's fucked. RIP WD93028-X... a bit annoying but there are a few of them around on ebay. Anyway reassembled the machine and everything is working as it should and looking sweet if you ask me. Decided not to retrobright this as I'm not going to keep it so whoever it ends up with can make that call. Will be in the Retro FS section shortly.
