I went looking for some replacement parts, and ended up with a complete second IBM XT chassis, and another complete XT.
The XT chassis is incomplete and has some sheet metal missing as it was previously converted to hold a Pentium 4 board. It donated its screws, plastics and fittings to complete the chassis of the restored XT. I had considered scrapping the rest, but since these old XT cases are rather interesting in themselves, I'm considering having some welding done and then a powder coat so it could be used to hold a newer machine. Perhaps an AMD Ryzen machine in an IBM XT chassis?
The second machine is an unmarked XT clone. This case needed some repairs as well, and I'm currently in the process of rebuilding it and replacing some missing rivets that were holding it together. I'm confident I can make this second XT machine work as well, so now I'll have two systems to mess around with.
I also purchased some other new components for the machine, including two Western Digital MFM/RLL controller cards, a LaserROM CD-ROM controller card, a complete set of genuine IBM MFM cables and replacement cork keyboard and case feet. Also included but not pictured is a Microsoft InPort Bus Mouse and controller card and an XT-IDE drive interface card with 64MB of CompactFlash storage for data transfer.
The cork replacement feet were a find in themselves. These are replica replacements, made of the same material and grain and custom made to IBM specifications for diameter and thickness. I didn't expect to ever find a set of these.
With the replacement cork feet and the plastic screw cap from the donor chassis, I was able to finally complete the underside of the machine, more than a year after the chassis was repainted.
With the screws from the donor chassis, the XT now has a complete set of IBM factory genuine hex-slotted zinc plated screws as well, with enough spares left over should the machine ever need them.
The Seagate ST-412 had to be removed and has since been shelved due to the condition of the motor assembly. The bearing whine became progressively worse and while the drive still works beautifully, I would rather have something in better condition in there. The machine currently has the factory MiniScribe 8425 reinstalled, but another drive like a Seagate ST-225 could be on the cards at some point in the future.
Next, I'll look into reattaching the factory labels and case badges, once I have the correct adhesives. If I order a replacement drive from overseas, I'll order a sound card for the machine as well. The video card still needs an aftermarket CGA-VGA converter to allow the standard video hardware to interface with newer displays. I'll be on the lookout for an appropriate era and model of IBM keyboard to match the system as well.
I have several other machine projects on the go as well now, including the Clone XT, two 486 based machines, a Commodore 64 and another Commodore machine that I'll give everyone a sneak preview of...
...but that's another thread in itself.
