I occasionally find the need to try and work out what technology I used when, this page is a rather belated effort at capturing some of that information.
It may not be correct and it certainly will not be complete!
Introduction of IBM mainframe computers
Information Builders introduce FOCUS for IBM mainframes. I would later (mid-80's) learn and support FOCUS.
I Left school and did summer jobs for the next 3 years in a mainframe operations department using IBM mainframes
IBM’s “Document Composition Facility” product introduced using GML
Early ’80s sees launch of Acumen, an OLAP/BI language and database developed in the UK by Mars – based on Strategem. I would later (mid-80's) learn and support Acumen, developing a number of key business systems in it and writing a variety of utility functions including charting and date/time utilities.
I Started work in IBM Mainframe operations, also learned to programme in IBM’s APL mathematical language.
I Purchased a BBC “Model A” microcomputer and waited several months for it to arrive!
Upgraded my BBC Model A to a Model B. My first go at soldering electronics. Blew the ADC chip and had to buy a replacement.
Taught myself to programme in a variety of languages including BASIC, FORTH, PASCAL, LISP and 6502 Assembler.
Replaced the BBC Micro with an Amstrad 6128 running CP/M, big mistake, a very boring machine.
Commodore Amiga A500 launched.
Moved from COBOL programming to “Personal Computing”, mainframe style using ISPF, APL, Information Builders FOCUS (a 4GL reporting tool), a mainframe spreadsheet called DynaSoft Dynaplan (AFAIK the first spreadsheet to use 3 dimensions) and and 4th generation tool called Acumen (which would now be called an OLAP tool). Also taught myself PL/1 to do some utility programs. Document processing was done using a mainframe SGML based tool – a good early grounding for later HTML. Later on started to work with PC’s as well, OS/2 and IBM LAN Manager. Word processing using IBM Displaywrite then Lotus Ami Pro.
Acorn Archimedes launched.
Replaced my Amstrad with a Commodore Amiga 500, a fantastic and imaginative personal computer. Learned about computer video, 3D imagery and rendering. The Amiga used Rexx for a system-wide scripting and automation language. I'd first learned Rexx on IBM mainframes.
Lotus introduce IBM mainframe version of 1-2-3 spreadsheet (DynaSoft release Dynaplan v4.0 same year).
ARPANET ceases to exist, Archie released, first commercial dial-up Internet provider.
Moved from Mainframes to PC’s full time, Introduced to Lotus Notes (release 2) and loved it. Got my first palmtop, a Psion 3. Got myself an Amiga 3000 under Commodore’s developer program. Great for 3D modelling (Imagine, Real-3D and Lightwave) and experiments with video.
WAIS, Gopher and WWW started, PGP created.
Demon Internet Services started up in June, 1st low cost (£10 per month) service in the UK.
Got my second palmtop, a Psion 3a. The Amiga’s got stolen along with all my disks and backups!! Replaced them with an Amiga 4000.
“Official” start of SPAM (US law firm Canter & Siegel spam Internet newsgroups)
Moved from using FIDOnet to the Internet thanks to Demon Internet Services.
Finally got my first PC at home after holding out for so many years!
Demon Internet offers ISDN access for £10 per month
Got my 3rd palmtop, a PalmPilot Professional
Acorn leaves the personal computing market.
Got PC number 2, an AMD 1200MHz based one with 512MB of RAM.
Got my 4th palmtop, a Sony Clie PEG-T625 (Palm OS 4.1)
Finally got broadband! Say bye-bye to Demon Internet, hello to PlusNet.
Got an iPad 1 32GB.
January – Got a Humax HDR Fox T2 personal video recorder. Freeview HD, 2 channels.
February – Got iPhone 4 32GB – A massive step up from Windows Mobile.
Apple iPad 2 introduced
