- I keep on seeing posts about the Psion 3...I've never seen it. I once
- owned something made by Psion, though. It was about 4'' x 9'' x 1'',
- and tall, not wide. The case kinda slipped on from the bottom. On the
- top were various ports, and I also had a bar-code reader for it. What
- was this machine, (I no longer have it) and how does it relate to the
- Psion 3?
-
- I was looking through Byte and they had a ad in the back for the
- company selling something they called "Palmtop computer", for $300. It
- looked kinda one of the Franklin dictionaries, but had the word Psion
- on it. What is this?
-
- In general, a short review of the Psion 3 would be great.

- Greg,
-
- I purchased my Psion 3 about 2 months ago. It is a MS-DOS-compatible
- machine running an 8086 processor. However, it has its own
- menu-oriented operating system, which gives it a very easy to use
- interface. This OS is also process-based, so you can have multiple
- things running simultaneously.
-
- It comes with a MS-WORD-like word processor, that has text-style
- capability, and can even show proportionally-spaced text (unusual for
- a palmtop), boldface, and italics. It also comes with the standard
- agenda, phone book data base, alarm, password, and world map
- capabilities that most palmtops come with, since they are primarily
- targetted to execs. There is a nice, full function calculator with
- scroll capability, and hex format for us hackers. It can even dial
- touch-tone phone numbers.
-
- However, unlike most other palmtops, the PSION has a distinct
- programmer-flavor to it. It has a built-in program editor, and its
- own programming language (called OPL - a funny combination of BASIC
- and Pascal) and compiler. OPL gives the programmer very easy access
- to the menu, windowing, and graphics capability built into the
- machine, making it very easy to write applications with nice
- interfaces. OPL functions can even be incorporated into the
- calculator, so that you can write your own calculator functions. An
- OPL manual comes with the machine. There are indications that Psion
- also has a C compiler for it, but I have no info on this (wish I did!).
-
- The case, when closed, is 6.5" x 3.5" x .875". It fits easily into my
- old HP41C leather case. The LCD screen is 16 lines by about 40
- characters (about 40, since I use the proportionally spaced option).
- The screen contrast is adjustable from the keyboard (another unusual
- option for palmtops). There is an auto-off capability that is
- settable. When the machine is shut off, it remembers EVERYTHING, even
- what you were last editing, and anything that was running. I
- previously had one of those Casio organizers, and it had an auto-off
- mechanism that was not settable (hard-set to about 5 minutes) and that
- couldn't be turned off (the Psion's can), and it lost anything I was
- working on (unless I manually saved it) when it shut off. I returned
- it after about 3 days because of this brain-dead feature. Some Casio
- design engineer should be hung by the thumbs for that one.
-
- The keyboard is QWERTY, but obviously smaller than normal. It takes
- some getting use to. I myself am not too fond of the pressure
- required by the keys (that Casio was nicer there), but have gotten use
- to the spacing. Some standard symbols have been re-arranged to allow
- use of the calculator without using the shift key (+ and * are
- unshifted).
-
- I also purchased the Link cable and software for IBM PC's - it gives
- the Psion full file transfer capability. The PC hooked to it becomes
- essentially a remote disk(s) that the Psion can access directly from
- its menu-oriented OS. Word-processor files can be converted into and
- out of RTF format for transfer to and from MS-Word and other WPs. The
- Link can also drive a printer - but I haven't tried this.
-
- It has 256K of builtin RAM, which is shared by the OS, applications,
- and files (initially, the OS takes up about 45K). There are two
- expansion slots. Psion sells their own memory cards and ROM packs.
- There are two types of RAM cards - "Flash" cards that operate like
- EPROM and need no battery backup, and normal RAM cards that do need a
- battery backup (lithium hearing-aid type). RAM cards range up to
- 2Meg, so a completely populated Psion can have 4.256Meg available.
- The flash-cards must be bulk-erased, and so cannot be used to extend
- the OS/application dynamic memory space - they're for files only.
-
- The machine runs on 2 AA batteries, and a lithium hearing-aid battery
- for emergency backup. After 2 months of everyday use, I just replaced
- the AA cells (it tells you when they're getting low). It can also
- take a 9v external power source. Mine cost me $350.
-
- I have recently received a copy of the Psion newsletter - you get it
- for sending in the warranty card. Psion seems to make all sorts of
- hand held computer widgets - a new one even has built in cellular
- phone data communication capability. Psion recently moved from
- Connecticut to Concord, Mass (their headquarters is still in England,
- I guess). The address is:
