Steve Jobs' Macintosh -- the machine that my kids and I will remember ... forever!

We Didn't Own an External Disk Drive, BTW

And notice that the word, "Macintosh," wasn't even on the front of the original Macs.

The specifications shown below (taken from were enough, even with only 128k RAM, to enrapture my family for years--although I did upgrade to 512k somewhere along the way. Imagine! That's only one-eighth of a kilobytes (a thousand bytes--where a byte was/is only eight bits)! Today, with megabytes (millions of bytes), gigabytes (billions of bytes) and even terabytes (trillions of bytes) showing up in the specifications of active memory ... we can't even imagine what's in store for tomorrow.

Thomas Edison, stand aside ... you have company. Steve Jobs was indeed an inventor of the first order.

I think you are looking at another posting--one I had of Chris Christie, no?

Halcyon days, those first Mac ones. Much like the Apple ][+ ones. A new world indeed.
