Another 'unboxing' - An IBM PS/2 'Model 30SX'?

Another international package received - this time from Canada (Thank You, Nikolai!). Years ago I joked about creating a PS/2 "Model 30SX" by putting a 25SX planar into a Model 30 286 case. It never got any further than a mock-up level. But several months ago, I noticed an IBM BIOS model referred to as a "30SX" - at the same time of study on an SVGA chip also being in the PS/1 "Pro" 2123, described as "using a Model 30-style case".

IBM was already planning a 35SX and 40SX (that also use the same SVGA chip) for an ISA PS/2 planar based on the 386SX-20MHz CPU. So instead, the "30SX" planar and riser were re-badged as a PS/1 model. Having this planar will help me immensely in populating the additional 72-pin SIMM socket, as well as demonstrating the 512Kb VRAM expansion.
