Okay, here's a LISA engineer talking about seeing high resolution graphics at Xeorx back in the 70s.

And the LISA guy is talking smack about the software limitations of the Xerox star (and with good reason, IMO.)

Gary just name dropped Allen Kay and smalltalk.

I've never used CP/M before, and never seriously thought about it before today.

Any grizzled CP/M veterans out there wanna give me the rundown?

I still love Gary, just FYI. He's the best.

On to Episode 2! (I'm going to continue liveblogging.)

Looks like the HP 150 used an 8088, and was not PC compatible.

Ran a custom DOS version. The touchscreen was infrared based, and the computer was "difficult to program" according to BYTE magazine.

And now the HP sales guy is going off on voice controlled computers, and everyone else just kind of side eyes him.

I'm really enjoying

The IBM dinosaur is talking about LANs and how important they will be in the future.

And they Gary jumps in and says, essentially "Yes networking, but not just LANs. LANs are complicated and expensive", and then describes, more or less, the internet.

I really like Gary.

This HP has a printer built in to the monitor.

It uses a 3.5" floppy, has an integrated touchscreen, and a built in printer.

I wonder what OS it uses.

Oooh, Gary is throwing all kinds of shade.

Talking about arm fatigue. Talking about how slow touchscreen interaction is.

But the key takeway remains tight hardware/software integration, which is sorely missing.

This HP salesman is actually doing a good job selling a device with software well integrated to a touch screen.

And Gary follows up asking "do you foresee the touchscreen replacing the keyboard?" and he's kind of smug about how no one is going to re-write their software to interact with a touchscreen.

(I type, with an onscreen keyboard.)

HP 150 - an HP with a touch screen, and an electronic roledex in 1983.

Also, they just put this guys phone number, area code and all, on blast right up on the screen.

I am seriously so excited about this show, and I'm learning so much.

Seriously though, I'm watching the guy that coded CP/M argue with a member of IBM's Mainframe team from back in the 50s.

As far as the history of computing goes, especially in the 1980s, this is the scrappy underdog taking swipes at the grizzled veteran.

(Except that this is almost 10 years after the release of CP/M, so he's not an underdog anymore)

@ajroach42 It was eye-opening for me when I realized the one host, Gary Kildall, created CP/M.

If you'd like to follow along, I'm about 15 minutes in to episode one (decision support systems)

I keep having to pause and watch certain segments over again, because there is *so much* information, and I don't want to miss any of it while I comment on it.

And okay yes, Mad Shade is a huge overstatement. He's being very polite.

But he's *so* *clearly* being just a little derisive towards the mainframes.

And I love it, because the micros represented a fundamental shift in computer culture, a democratization of computing power.

I admire the mainframes for a lot of reasons, and I'll get in to that at some point, but I *love* the ideology of the early micro camp.
