So this is my IBM Personal System /2 Model P70 and it’s not quite a laptop, it’s actually known as a portable computer, luggable pc or as I like to call it the suitcase computer. This unit runs on AC power and does not come with a battery.
The P70 is unique as it actually uses a standard PC motherboard, it was designed by utilizing parts from IBM PS/2 systems and quite a few parts are interchangeable, plenty of room in this unit for upgrades with two expansions boards.
The P70 really was a high end computer at its time of release in 1988 and it is more closer to a server than a desktop.
My P70 is a 386DX-20 (20MHz), 4MB of RAM, 60MB DBA ESDI hard disk, 1.44mb Floppy and runs IBM DOS 5.0 and Windows 3.0, I actually found this P70 for $25 and to my surprise it is in absolute mint condition with no broken plastics and fully functional, funny enough when I checked out the details in Excel it was registered to “Campbell Soup Company” and it looks like it has some machinery line software installed.
The P70 has a very bright orange Plasma display, these displays became very common on Laptops and Portable computers during the late 80’s due to the high contrasts available compared to the STN LCD technology at the time. The P70’s display is very cool, it can be pulled out for an adjustable viewing angle.
My only complaint of this unit was the lack of a 16 pin serial but other than that it is a great unit.
