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

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.

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.)

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 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.

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.

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 #computerchronicles

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.

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

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?

@ajroach42 What do you want to know? First real micro OS. MSDOS borrowed a lot of ideas from it.

@ajroach42 Worked great. Ran a BBS on one for years. The MSDOS file tree is better than CP/M, but it looks and feels like MSDOS for the most part.

@Ricardus I know that CP/M was available on many different hardware architectures.

I'm assuming software would need to be cross compiled between systems, and there wasn't some kind of early VM?

@ajroach42 I've run CP/M emulators on MSDOS, but not a VM as we know them today. I think CP/M was mostly on Z80 machines.

@ajroach42 That video has a demo of Concurrent DOS, and I love how one of the other guests on the show says the multitasking OS brings no real value to the table because it's not really an app that does anything. And we're going to have to sell the general public on the idea of multitasking. 😃
