IBM PS/2 Model 55 SX WORKING! w/ IBM PS/2 Mouse Excellent Shape!

Description

IBM PS/2 Model 55 SX WORKING! w/ IBM PS/2 Mouse Excellent Shape!. Shipped with USPS Priority Mail Large Flat Rate Box.
This 55 SX has been confirmed working as shown by the screenshots with an accompanying IBM 8515 Color Monitor, available elsewhere on my page (Unless bought, then disregard this and move on while whistling innocently). It is 99% stock original parts, the only exception being a replaced Dallas 1287 Clock Battery. This system will be shipped with accompanying cables, a copy of the IBM 55 SX Startup Disk that we burned, four spare Dallas 1287 Batteries, and an IBM PS/2 Mouse in excellent condition.
Cosmetically as you can tell, it has basically no yellowing, internal corrosion or leakage, powers on reliably, albeit the video out can be a tad finicky from my experience. It also shows Errors 162 and 163 on startup which we were unable to address. HDD has not been tested but it was respondent to keyboard and mouse input during testing.
