Hewlett Packard HP 620LX

Technological improvement occurred rapidly during the late 1990's with regards to portable computing and the Hewlett Packard HP 620LX is a fine example of this (with some caveats). The 620LX was the follow up to the HP 300 series, one of which I reviewed here. Released in 1998, the 620 took the basic premise of the 360 and added new bells and whistles to make it the then go-to model. These included a new version of Windows CE (v2.11 compared to 2.00), a faster SH3 processor (75MHz instead of 60MHz), double the memory (16Mb), more ROM (10Mb) and most obvious of all, a colour screen. Now before anyone gets too excited, when I say colour, I mean 256 colour CSTN with the same 640x240 half VGA resolution as the 360, so nothing special even compared to the laptops of the time. However, colour was something new and it was a useful feature to add, certainly making the built-in Internet Explorer somewhat more user friendly. All this for a launch price of £699 ($899). In today's money, that's north of £1,200.00!!!

That's the extended battery right there. The case is nifty too.

First up, that new tech meant a bigger device, and, as you can see from the picture below, it’s a fair bit larger than the 360LX and the much older Psion Series 3. The card is for scale. That extra space didn’t entirely go to waste as the keyboard, whilst keeping the calculator style of the 360LX, has slightly larger keys and they are more widely spaced. This does mean that it is easier to type on and I got up to a decent, accurate speed with it. It's still not in the same league as the follow up Jornada series or the Psion 5's (yet to be beaten) exemplary keyboard. There are also some application softkey shortcuts above the keyboard and four to the right of the screen.

Yes, I still buy books from a high street shop! What's your problem??? ;-)

It certainly looks the business.

As the device has a colour screen, the keyboard and symbols have a splash of colour themselves and the unit itself is a rather tasteful black rather than the dark grey of previous models. Think Psi-Corps compared to the dull Earthforce Security...

Also doubles as a make up mirror. So I am told...

A note on that screen. It is very readable but uses that popular tech of the time, the resistive touchscreen. This means that you really need the included stylus to get any real use out of it and it’s reflective as hell, as you may have noticed from the pictures. Being CSTN, it does appear rather washed out but you can change to contrast to help out with that.

That reflection is me taking the picture. Told you it was reflective...

That extra bulk (1.29 lbs vs 1.01 lbs of the 360LX) meant that the newer machine was no longer a jacket pocket “whip it out when required” (oohhh-errr, missus!) device. Nope, the 620LX was just too damn big and that was with the smaller battery. The picture with the carry case also shows the extended battery that adds a smidge more weight and sticks out of the back of the device. That said, the extended battery does mean you can make it through a full working day with extra to spare, not something that could be said of the standard power pack.

As per the 360LX, the software is the usual Windows CE mix of office applications and utilities, with just what seems minor enhancements. There is the expected compact flash card slot for additional memory and a PCMCIA Type 2 slot for network, modem and VGA adapters (amongst other things). A word of caution here though: any use of the PC card slot means a dive in battery life, and the extended battery isn’t much help here.

What makes it useful to this day, removable storage.

You can also get a very fragile docking cradle that acts as a syncing aid, but in reality, is neither use nor ornament and its true purpose was to take up desk space at home when you weren’t being an always connected on the road net-warrior (how '90's!).

Even with two rather suspect batteries, the 620LX is still very usable today and, if using a rucksack or other large bag, would be the go-to device if I couldn’t carry the Alphasmart. That would also include a mains adapter as twenty year old battery cells are unpredictable, as well as a spare back-up battery as those coin cells get chewed up pretty badly when the main battery goes. And that pretty much sums up the caveats with this device. It's a bit too large as a handheld and the move to a colour screen meant ditching the ubiquitous AA battery for a lithium-ion pack that also meant carrying the mains adapter around for when the pack inevitably died. 

620LX, 360LX and Series 3 - at least the screens got bigger.

Upon its release, the 620LX was described as a laptop killer. Bigger and of more use than a PDA, smaller and more portable than any laptop at the time, it seemed to be the perfect middle ground. Yet, as time was to prove, it wasn’t. Practical use was hampered by the form factor (the keyboard too small for real touch typing, the screen too small for more than one person to view at a time) and the abomination that was Windows CE/Handheld PC – an operating system that never truly knew what it was supposed to be. Tech also improved with laptops and when you’re paying seven hundred quid for something, you want it to work well. Ultimately, business users (for that was who HP were aiming for with the 620LX) didn’t jump ship to the product and by the time the Jornada 720 was released in 2000, the writing was on the wall for the device format.

Pretty similar but the bigger keys do it for me.

That is not to say that some silly fools continue to try to get some use out of these devices and as I said above, it’s a handy machine and a good back up.

This will be the last of the retro tech pieces I’ll be doing for a while, the main reason being that I have pretty much bought the machines I wanted to and these cover pretty much everything I need (and there is no way I am paying that much for an Apple eMate 300!). You could say I am a fool for using this old tech but to be honest, it works for me. I am not a fan of touchscreen keyboards, adding a keyboard to a tablet is akin to adding a chocolate handle to a frying pan and modern day small keyboard devices are rather expensive. So with that, if you’ve missed any of my previous pieces, the links below will take you to them and below that, a picture of the collection:

A Psion of the Times

If you are of a certain age and have an interest in tech, the name Psion may mean something to you. Coming to prominence during the 1980's home computer boom as both a hardware and software supplier, Psion rode the wave and successfully launched a range of electronic organisers, helpfully called the Psion Organiser, that whilst clunky and very 80's looking, their job well enough to gain a dedicated following. This allowed them to progress from the calculator-like Organiser II with a pocket computer that defined the company into the 90's and still, to this day, gives certain individuals a sense of glowing nostalgia when seen in public.

The Series 3 was their first clamshell design, one which nailed the brief spectacularly. What you get is a pocket-friendly device with a hunt and peck keyboard that, by good design, is pretty much capable of decent typing speeds with a bit of use. This is down to the well-spaced layout and the slightly concave keys that help guide the fingers accurately. True, like all Psion clamshell designs, there were issues - namely a slightly fragile hinge and a ribbon connecting the gubbins in the bottom half to the screen that could fray and cause display problems, but that does not take away what they got so right with the Series 3.

There is a screen in there somewhere...

It's alive!!!

The screen, however, is a compromise, fair enough really given the year of release. As you can see, the screen on the original Series 3 is a bit lost in the lid and has a relatively poor resolution of 240x80, and that is one area they improved upon with the following Series 3a, where the display was not only physically bigger but offered a resolution of 480x160. The main processor is an NEC V30 running at 4.7MHz (a reverse-engineered copy of the Intel 8088 that powered the original IBM PC), coupled with 256Kb of RAM and 1MB of ROM that held the EPOC 16 operating system. Not exactly heady stuff at the time but then it did run north of 20 hours on two AA batteries.

A bit of Word.

A World Clock, circa 1991

The aforementioned Series 3a offered the bigger screen, a faster (7.68MHz) processor and double the RAM (and later 1 and 2MB models). The 3c (one of which I carried at university and sorely wish I had never sold on afterwards) bumped the RAM up to 2Mb and had a matte exterior (whilst some US models added a back-light to the display).Finally, the 3mx all offered a back-light and faster NEC V30MX processor running at 27.648 MHz. At that point, the Series 3 was retired for the Series 5.

Now I mentioned the batteries and their expected lifetime. Time was that the AA battery was ubiquitous and if you need to, replacing them was just a shop visit away. These days, with densely packed lithium battery tech, all I can say is good luck with that. True, high resolution colour displays and multi-gigahertz-clocked processors require that kind of power supply, but sometimes it would just be handy to be able to swap out old for new (or rechargeable) ones.

Anyhoo, back to the Series 3. The batteries are kept in the hinge and are easily accessible. The hinge itself is still pretty firm and doesn't feel in anyway compromised by the years of use - not bad for something made in 1991! That same hinge, on the interior, gives access to eight soft-keys - shortcuts for the built-in applications: System, Data, Word, Agenda, Time, World, Calc and Program. Pretty self-explanatory but as memory serves, both the Agenda, Data and Word applications were bloody good for their time and proved more than useful twenty years ago! In fact, I don't think I have used a better calendar application ever. The Program soft-key is of particular note, as having a programming language baked in meant that those who wished could program their own applications for the device.

Check out those short-cut keys.

Connectivity was well catered for too, with two expansion slots for Solid State Disk memory cards and software packs, and a proprietary connection for a serial cable. Later models also offered an infra-red connection.

Using the device today, the screen is pretty easy to read in decent light and the lack of a back-light isn't an issue. The small amount of RAM isn't too much of a hurdle either given what the device was used for and if you wanted to do any serious typing, a memory card was easy (if not overly cheap) to add. The example I have was purchased off E-bay and though the battery contacts need a good clean, it's in pretty good nick. There are always quite a few Series 3 models available but be warned, the more recent 3c and 3mx models go for near £100 or more, proof that they are still in demand today. A quick Google located a UK based company advertising new and second-hand Psion devices so, without doing any advertising, if you do want a Psion of your own, you know what to do.

The biggest hurdle for anyone under the age of 30 using anything like the Psion is the lack of a touchscreen. You see, back when the Series 3 was released, touchscreens were a rarity on portable devices so navigation is purely via the keyboard. There is a menu button and the on-screen menus are very well laid out so with a bit of practice, you'll be zipping about in and between applications with ease. For pretty much any option, there is a suitable key-based shortcut. True, it is not as intuitive as a mouse pointer or a touchscreen but for the time of release, this was pretty good. Indeed, anyone with a passing knowledge of DOS would feel pretty much at home here. How many there are of you in this day and age is up for debate! But in any case, the Series 3 is very usable and with only a small amount of practice too.

Is this a serious tool for 2018? Well, depends on what you want to use it for. As an organiser, the software is brilliant but there is the issue of connectivity and syncing software for the modern day PC. You can get serial to USB cables and a quick search online brought up a handful of useful articles so yeah, certainly with a later model with the higher-res screen, they are certainly usable today. Would you want to pay for one, well that is another matter...

On that note, I'll leave the blog for now, what with Salute at the weekend and then another appearance on Attention Please on Monday evening with Eddie Carter. If you fancy a listen, we're on 102.5FM in the local area or you can click on the Listen section here on the NE1FM website.
