IBM Personal/370 Processor

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

From datamuseum.dk (via Google Translate):
   The P/370 is a plug-in for an IBM PS/2 with 32-bit Micro Channel. The card has 16M / 370 storage. (...) The card supports VM / System Product, VM-ESA 1.5 (370 feature), and corresponding MVS and VSE".

Cards associated with the P/370 (these do NOT provide ability to run 370 code):

  • S/370 Channel Attach
  • S/370 to MMC

Other "Personal" S/370 Products

   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)

IBM 7437 Technical 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".
