I am sure most of you, just like me too, want to get their hands on the lightest laptops possible today. We are all looking for portability.
So,what did the first commercially available portable computer have going for it? Well, it was super light at a whopping 55 pounds. It also cost $19,975, more than some cars do these days.
Have a look:
Yep, that’s a “laptop”. Kind of. Here’s the full details on the IBM Portable PC, model number 5100:
First introduced: September, 1975
CPU: IBM proprietary, 1.9MHz
RAM: 16K, 64K max
Display: 5? monochrome monitor 64 X 16 text
Storage: Internal 200K tape (DC300)
Ports: tape / printer I/O port
OS: APL and/or BASIC
When you check out the Wikipedia page for the IBM 5100, here’s what it says:
A single integrated unit provided the keyboard, five-inch CRT display, tape drive, processor, several hundred kilobytes of read only memory containing system software, and up to 64 KB of random access memory. It was the size of a small suitcase, weighed about 55 lb (25 kg), and could be transported in an optional carrying case, hence the “portable” designation.
So it was the size of a small suitcase? Yeah, how’s that for portable? If you ever find yourself complaining about how clunky and big your gadgets are, remember this guy lugging around the $20k “ultra portable” IBM 5100:
