1988 – While not the first version of the PS/2, the Model 70 was introduced with the 80386 processor. 16, 20, and 25 MHz clock speeds. The Model 70 also used a 25 MHz Intel 486 processor in a complex called the Power Platform.
If you wanted to upgrade to the 80486, you would have to replace the PS/2’s BIOS chip along with the processor board.
The model 70-A21 sold for $11,295 and included 2 MB of RAM, 120 MB ESDI hard drive, MS-DOS and OS/2. If you wanted a monitor for it, you would have to put down an additional $595 for the 8512 VGA.
Model 70 was a desktop case and Model 80 was a tower. IBM also introduced the PS/2 Model 25 LS and PS/2 Model 50 Z.

Microsoft Released Windows 286 and Windows 386 on May 27, 1988
1988 – In competition to IBM OS/2, Microsoft releases 2 versions of Windows 2.1x – One version for x286 computers (aka Windows 286) and one for x386 computers (aka Windows 386). Windows 2/x386 introduced the protected code Kernal – applications would run as a virtual 8086 mode, and MS-DOS programs could run in parallel. Windows 2/x386 also provided EMS emulation, which would give Windows memory management features. System RAM beyond 640k could be used, and felt like banked memory. Finally, it has a Presentation Manager mode, to compete with OS/2
Windows updated this software to 2.11. It was finally retired when Windows 3.0 was released in 1990.

Windows 386 full video. Linda needs to save the client, so she loads Windows 386 with Presentation Manager
This was the promo video for Windows 386. It starred Victoria Carver (as Linda) as an executive who had to save a client. She was given a task to make a presentation by 5 pm. She decided to load and use Windows 386 to build this presentation. Using the “Mission Impossible” theme throughout, Linda is confronted by a fellow employee – Mike the mainframe guy. He wants to help Linda out, but Linda knows that the mainframe subroutines simply take too long to write. He then spots Windows 386.
“You are not suppose to be running OS/2 – we haven’t finished evaluating it” Said Mike, the mainframe guy.
“It’s not OS/2. It’s Microsoft Windows 386. It has the same interface as the OS/2 Presentation Manager. So, when OS/2 is recommended, I’ll be ahead of the learning curve.”
“As usual. What else does it do, besides look like OS/2?”
At this point, Linda shows Mike the interface. Of course, Linda then creates the presentation and keeps the client. The video is written like a cheesy 80’s soap opera, and goes on for twelve minutes.
