On Hardware 5: Printers

To round off this series, printers. Given that my business produces software which churns out pages of calculations, printing has always been important.

My first ever printer was a dot-matrix printer coupled to my Commodore PET – it was an Epson TX80 dot-matrix printer customised to work with the PET – very slow, very noisy. You can see an example of the output on this Greentram museum page. When I moved to a BBC computer, it was replaced by a Star NL10 which became my first PC printer, then being replaced by a Star NB24-10 which gave much better resolution.

Along side these, my correspondence (my plan drawing business lasted until 1992) was printed on daisy-wheel printers. Initially I had a Silver-Reed EX-44 electronic typewriter with added computer interface. A Triumph Adler TRD7020 (1986: £148) followed; it was built like a Rolls-Royce and was bought from Boots when they gave up their unsuccessful home computing venture. It sounded like a machine gun when printing at speed! The third, a Silver-Reed EXP800 wide carriage printer was bought from Morgan (1988: £250) – I was amazed to find that ribbons for all these printers are still available. Wikipedia reminds me that “Most daisy-wheel printers could print a line and then, using built-in memory, print the following line backwards, from right to left.” This was always memorising!

The first SuperBeam manuals were originated on the NB24-10 printer, then photocopied, but it was obvious that something better was needed, so 1989 saw me finding £1426 for a Brother HL8E laser printer. This gave good service until it was replaced in 1995 by a Lexmark Optra S with duplexing, £1,643. This was a lovely piece of work but in the end the duplexer wore out (too many church newsletters!). It was cheap to run too, courtesy of a Wembley supplier of remanufactured cartridges.

Needing a new printer and doing a lot of printing and copying at the time (1999, well before everyone was using the internet), I took a very deep breath and shelled out £4,610 for a Canon GP215 copy-printer – initially I’d thought machines like this to be far too expensive, then was tipped off that for copiers the going cash price was around 50% of list, the latter being set so as to make lease deals look cheap.

Time proved the Canon to be one of my best purchases ever: it was still going strong when I emigrated, having printed several hundred thousand pages at less than 1p per side. The six bins each held a different colour paper – long standing users of SDA’s software will remember the product leaflets on different colours (SuperBeam: gold; SuperHeat: green; ProSteel: purple) and the personalised blue order forms. The printer selected the required colour without manual intervention.

Meanwhile two other printers were at work. A 1994 Epson LQ570+ (£199) did sterling work printing continuous feed floppy disk and address labels by the thousand. Then when we switched to CDs a HP DeskJet 950 printed CD labels.

Here in Australia? I now do very little printing compared with times past. My current printer is a top of the range Brother mono laser with duplexing, current cost about A$500 (say £250). It does much the same as the Optra, 15% of the cost. Nice, but as with monitors, nothing to stun a 1990 time traveller!

On Hardware 4: Monitors

This part is a bit different: no astronomical drops in price, just more year on year for the same money.

Pre-PC, my Commodore PET came with its built-in mono screen, 9”, 40×25 characters. Then my BBCs were coupled to the default Microvitec Cub 14” 1431 colour monitor.

On to PCs. My Dell came with the optional VGA monitor, resolution 640×480 pixels, when many users were still using EGA (640×350) or CGA (640×200). My next three monitors were all 15” VGA, costing around £200-250. The next step up was my 1995 Christmas present to myself, a lovely Idek 17”, offering a superb 1280×1024 resolution. It stayed on the books until 2001 and was a joy to look at.

Then the seismic change. November 1999 saw my first purchase of a TFT (flat screen) monitor, a 15” Panasonic LC50S, 1024x768px. As it was an ex-display model I got it for ‘just’ £637. Two more 15” screens followed, Nov 2001 (£385) and Aug 2003 (£205), then a 19” Benq FP91V in Oct 2005 for £257. Then in April 2007, a year before emigrating, these were replaced by a pair of HP W20 screens for £144 each.

On coming to Australia I started with a couple of Samsung monitors 22”/24” each costing around A$300 (say £150). Surprisingly one failed after a couple of years and was judged beyond economic repair. I’m writing this looking at a 2015 27” LG monitor which I plan to keep for a good few years yet, supplemented by a Hisense 43” 4K TV which serves as a second screen and is used for 4K testing.

So unlike some of the other posts in this series, perhaps not much to see here? A 1990 time-traveller would be dumfounded by 2TB drives for little more than pocket money; as for today’s monitors, polite appreciation at best?

On Hardware 3: Storage

This post covers memory and disk storage. Both have shown a fall in price that would have been unimaginable 30+ years ago. And with the advent of SSDs and memory sticks, the two are now closely intertwined.


In 1979 I started with a top of the line 32K Commodore PET – £100 more than the 16K version – so that’s £6,400 per MB. 1983 saw a BBC B with 32K, then 1986 a BBC Master with 128K. Then in 1989 I joined the PC world, my first Dell having 1MB.

By 1992 4MB was the new norm; late in the year 4MB cost me just £72 – £18/MB. During this time memory prices fluctuated significantly, 16MB costing me £429 in 1994.
By mid 1996 a 16MB SIMM cost just £85 – just over £5/MB. Then it was 32MB sticks: £100 in August 1997 and £68 six months later – £2/MB, then June 1998 I added a 128MB stick for £99, breaching the £1 barrier. June 2001 saw 256MB for £96, 27p/MB and that was the last memory I bought – since then I’ve bought ready built systems with more than enough memory.
But today? On Googling UK component suppliers and picking the first, I can buy an 8GB stick for £37 – that’s less than 0.5p per MB – or to look at it another way, at 1979 prices 8GB would cost just over £52 million!


Pre-hard disk, my PET and first BBC used cassette tapes for storage. Adding a floppy disk drive to my second BBC cost around £400. Then for my first PC, I paid extra for a 40MB hard disk instead of the standard 20MB. For the next 20 years I was buying ever bigger hard disks – now I’m nowhere filling the one in front of me.
Some purchases along the way – price per MB in brackets: Mar 92: 130MB/£264 (£2.03); Aug 93: 340MB/£249 (73p); Jun 95: 540MB/£139 (26p); Aug 96: 1GB/£119 (11p); Jun 98: 6.4GB/£129 (2p) and my last separate HD purchase, Sep 01: 40GB/£133 (0.3p).
And now? You can buy a 2TB drive for £54 – that’s next nothing per MB, though SSDs, given their falling price, are now almost universal. 2TB at 1992 prices: about £4.25million!

USB sticks

Disk or memory? You decide. 64GB for £6 – unbelievable to those of us who remember what memory used to cost.
