This card as best I can determine, was never directly offered, but was available only by contacting IBM. Pretty uncommon...

   "IBM 7437 Technical Workstation" IBM 7437 VM/SP Personal Workstation

As of November 1988, IBM was shipping a workstation version of the System/370 hardware intended to run IBM's VM/SP operating system. Officially called the IBM 7437 VM/SP Personal Workstation, it was a freestanding tower that connected to a MCA card installed in a PS/2 Model 60, 70, or 80. One IBM representative described the 7437 "like a 9370 with a single terminal".

Also, this thing is part of a whole family of mainframe-on-PC hardware and software that the VM team was largely responsible for.
* XT/370 (basically two hacked 68000s with partial S/370 emulation microcode, enough to get CMS running)
* AT/370 (ditto)
* 7437 VM/SP Technical Workstation (a PS/2 Model 60/80-sized tower, that you cabled to a MCA card in your Model 60/70/80, and gave you a full S/370)
* Personal/370 Adapter/A (faster 7437, on a card)

P/370 Complete  

"The P / 370 is a plug-in for an IBM PS / 2 with 32 bit microchannel. The card has 16M / 370 storage. My card was mounted in a PS / 2 model P75, a portable rebranded Hitachi with gas display, also known as the "sewing machine".

The card supports VM / System Product, VM-ESA 1.5 (370 feature), and corresponding MVS and VSE"  Please direct all mis-translation errors to Google Translate 

If anyone speaks Dutch, I'd like to get an ISO of the CD and IMG of the diskettes...
