===IBM 7437 VM/SP Technical Workstation===

In April 1988, IBM introduced a System/370 [[workstation]] that had been shipping to some customers since August 1987.<ref>{{cite magazine | last=Cortino | first=Juli | title=IBM 'personal mainframe' goes public this summer | magazine=PC Week | volume=6 | issue=16 | date=1989-04-24}}</ref> Officially called the IBM 7437 VM/SP Technical Workstation (and later also known as the Personal System/370), it was a freestanding tower that connected to a [[Micro Channel architecture|MCA]] card installed in a [[IBM Personal System/2|PS/2]] [[IBM PS/2 Model 60|Model 60]], 70, or 80. The 7437 tower contained the processor and a 16{{nbsp}}Mbytes main memory, and the PS/2 provided I/O and disk storage.<ref name=Cain>{{cite magazine | last=Cain | first=Matthew | title=IBM quietly sells a VM workstation: single-user system | magazine=MIS Week | volume=9 | issue=45 | date=1988-11-07 | page=8 |url=https://archive.org/details/sim_mis-week_1988-11-07_9_45/page/8}}</ref> The 7437 ran the IBM [[VM/SP]] operating system, and one IBM representative described the 7437 "like a [[IBM 9370|9370]] with a single terminal". It was intended for existing S/370 users and its November 1988 list price was $18,100 for a minimum 25-unit order.<ref>{{citation | last1=Fisher | first1=Sharon | last2=LaPlante | first2=Alice | title=IBM's VM/SP Device Cuts Mainframe Load | periodical=InfoWorld | volume=10 | issue=45 | page=113 | date=1988-11-07 | url=https://books.google.com/books?id=RzsEAAAAMBAJ&q=ibm%207437&pg=PT112}}</ref> One of its intended roles was to provide a single-user S/370-compatible computer that could run [[computer-aided design]] and [[Computer-aided engineering|engineering]] applications that originated on IBM mainframes such as [[CADAM]] and [[CATIA]]. Graphics support was provided by an IBM 5080 graphics system, a floor-standing tower. The 5080 was connected to the 7437 through the PS/2 via a cable and MCA adapter.<ref>{{cite magazine | last=Smalley | first=Eric | title=Quiet IBM Entry Lets Users Run VM on Desk Top | magazine=Digital Review | volume=5 | issue=22 | date=1989-11-21 | page=19}}</ref>
