[ Retro Scan ] HP 95LX

Hewlett-Packard HP 95LX HP-95LX Handheld Computer Pocket Computer Palmtop PC User's Guide Cover scan - 1991HP-95LX: Like a computer-shaped cookie that you can't eat

In case you didn't know, the HP 95LX is a small, portable IBM PC compatible machine running a full version of MS-DOS that ran off of two AA batteries. It marked the beginning of HP's palmtop computer line, which I wrote about recently in a slideshow for PCMag.com.

The HP 95LX is special to me in particular because I've had one for over 20 years now. My dad bought the machine slightly-used from a friend not long after it came out. After fiddling around with it for a while, he gave it to me, and by 1993, I had it in my collection.

Using an RS-232 serial cable my dad built for me, I managed to transfer some MS-DOS programs to it (a few text-mode games mostly, and a few HP 95LX apps I downloaded from CompuServe), that I remember taking to school and using once or twice just for kicks. I also used that serial cable to hook the 95LX to a modem so I could call BBSes with it.

The worst thing about the 95LX — aside from its 1/4 CGA screen that doesn't let you run many MS-DOS apps — is that if you don't have a plug-in memory card, you lose all your saved data on the RAM disk if it runs out of batteries. Sure, it has a backup coin cell battery (or maybe two), but if that runs out, you're out of luck. The PC Card-like memory cards cost a lot of money back in the 1990s, so I never had one until recently.

Still, it's an amazing little machine. Very capable — if you have the patience to use it. A few years later, HP got everything right with the 200LX, which is still a popular portable MS-DOS machine among certain diehards today.

The IBM PC Turns 35

August 12th, 2016 by Benj Edwards

Benj's IBM PC 5150

35 years ago today, IBM launched the IBM Personal Computer — the first-ever IBM PC. While it was simply called the "IBM Personal Computer" back then, we now know it more commonly by its model number, 5150.

PCWorld recently asked me to do something to celebrate this anniversary, so just a few days ago, I took apart my personal IBM PC 5150 and documented the process on my workbench. And back in 2011, I wrote some other articles about the IBM PC on the occasion of the machine's 30th anniversary.

In fact, I've done a lot of coverage of the IBM PC over the years, so I thought you guys might enjoy seeing a collection of all of them in one place. Here we go.

[ Retro Scan ] Disemboweled IBM PC 5150

June 30th, 2016 by Benj Edwards

IBM PC 5150 Apart Components Inside Advertisement Scan - 1982Is somebody gonna clean this mess up?

Here we have a biggole two-page IBM PC 5150 advertisement spread from 1982 — published not long after the launch of IBM's first PC in August 1981.

It looks like IBM is trying to play up the bare-metal technical angle for Byte readers, who likely were building their own PCs from kit parts just a few years prior (and some still were doing it then).

The result, quite frankly, is a huge mess (looks like my workbench). And the advertisement didn't come out too well in the magazine print run, which makes the image dark and muddy. It's not my fault, I swear!

I particularly like the phrase "the RS232C interface that gives you the world" in the advertising copy. It implies using the serial port for networking — that is, in connecting to remote computers. It's funny because back then, that statement was a hyperbolic boast that was not meant literally. Online services were limited to a teeny-tiny fraction of the world population and their capabilities were limited. Today, networking does really give you the world.

[ Retro Scan ] Dogs and Families Love IBM PS/1

IBM PS/1 IBM PC Dog Family Smithsonian Advertisement Scan - 1991Now you'll have more time to spend with your dog

I've previously featured a later-model IBM PS/1 that also happened to be my brother's college computer, circa '94. But here we see an ad for an early — if not the first — model of the PS/1. This is back when PS/1 systems had the OS and a nifty mouse-based GUI program launcher built into ROM. They also shipped with Prodigy on the hard disk. I'm starting to really want one of these for my collection.

[ VC&G Anthology ] Origins of the ASCII Smiley Character: An Email Exchange With Dr. David Bradley (2011)

November 6th, 2015 by Benj Edwards

IBM Smiley Characters
10 DAYS OF VINTAGE: Day 5

The famous IBM PC 5150 turned 30 in 2011, and I spent quite some time preparing for that important anniversary. During my brainstorming process, I thought it would be fun to celebrate the 30th anniversary of another famous cultural icon — the "smiley" ASCII character, which originated with that seminal IBM machine.

To me, the the smiley character (seen above in its original and inverse forms) is best known as the protagonist of pseudo-graphical text-based games like ZZT.

VC&G Anthology BadgeTo find out the origins of this whimsical denizen of Code Page 437, I sent an email to Dr. David J. Bradley, one of the creators of the IBM PC, whom I had corresponded with before. In fact, Dr. Bradley is best known as the inventor of "CTRL-ALT-DELETE" keyboard combination that once reset almost every IBM PC-compatible computer.

I never did get around to writing that Smiley celebration as I planned, but I just ran across my conversation with Dr. Bradley recently, and I still find it interesting. With Dr. Bradley's permission, I am reproducing a transcript of our email conversation below, which I hope will aid future IBM Smiley researchers in their quest for information.

[ Retro Scan of the Week ] IBM PS/1 Imagination System

September 14th, 2015 by Benj Edwards

IBM PS/1 Imagination System Box Scan Photo - 1994IBM and Disney go together like peanut butter and petroleum jelly

Just before my brother left for college in the fall of 1994, my whole family went shopping for a new PC to send off to school with him. We made our way to an IBM PC factory outlet near Durham, NC. Upon walking in to the store, I remember being amazed by rows of 20-foot tall warehouse-style shelves, each one stacked with large boxes for IBM PC systems. A salesman met us at the door and apparently steered my father toward this: the IBM PS/1 Imagination system. I guess it was a good deal.

The machine itself came equipped with a 25 MHz 486-SX CPU, 4 MB of RAM, a 2400 BPS modem, and a Disney Sound Source (a sort of primitive SoundBlaster that plugged into the parallel port). Unlike earlier PS/1 models, this one shipped with MS-DOS 6 and Windows 3.1. It also came with a suite of pre-installed Disney software that my brother promptly deleted.

My dad also bought an unusual IBM-brand external ISA CD-ROM drive that required its own peripheral card. There wasn't enough room in the PS/1 case for a CD-ROM drive and a 5.25″ floppy.

After college, my brother took this machine to work with him as a programmer, and he used it there until it was long outdated — probably until 1999 or so. It now rests safely in my collection, although the hard drive is now shot, and I think the power supply is fried too. Almost a decade ago, its rubber feet chemically decomposed into the most abysmally black and sticky tar that you can imagine. I need to restore the machine.

Just recently, I found the rather large shipping box for this computer sitting in my mom's attic. Today, it holds miscellaneous housewares. This "scan" is actually a perspective-corrected photo of the side of that box (here is the original photo).

[ Retro Scan of the Week ] IBM's Bizarro Alt-Reality PC

June 29th, 2015 by Benj Edwards

IBM Instruments Computer System advertisement - 1983The IBM Instruments Computer System

What a strange machine. The IBM Instruments Comptuer System was a completely modular 68000-based PC with its own custom OS (CSOS, according to Wikipedia, which stood for "Computer System Operating System" — ???). It also utilized Motorola's rarely-seen Versabus bus architecture. The ICS was aimed at scientific and engineering use, and it launched in 1982 — the year following the launch of the IBM PC 5150.

Has anyone used or seen one of these? This is an oddity of oddities. Thank goodness the IBM PC didn't end up like this.

[ Retro Scan of the Week ] Family Quizagon Night

Quizagon family Apple II IBM PC Commodore 64 VIC-20 computer game advertisement - 1983“Whoa…what’s in these brownies, Grandma?”

Thanksgiving is almost upon us again, so it's time to gather around your home PC for a game of…Quizagon?

Yes, Quizagon. A game I've never played, nor will I for the foreseeable future. It looks like a hexagon-themed family trivia game, which is not my bag, man. But what a great photo.

Instead, I'm going to host a The Seven Cities of Gold marathon on an Atari 800XL with my brother. We plan on exploring a completely new continent while interacting vigorously with the natives. Meanwhile, my brothers- and sisters-in-law will be playing Sonic & All-Stars Racing Transformed on my dedicated gaming PC that is hooked to the flat-screen living room TV. It's a great kart game to play on Steam with four Xbox 360 controllers that's easy to set up and jump into. Fun times shall be had by all.

By the way, I first used this amusing scan in a 2009 Thanksgiving-related slideshow I did for Technologizer (hoping I'm not repeating it on VC&G). If you're in the mood, here's some other Thanksgiving-related material from the VC&G archives.
