C > CIFER SYSTEMS > 2683   

Cifer Systems

The Cifer 2683 was the stand-alone version of a large range of dumb terminals released in the UK by the Cifer Systems Limited Company.

The 2683 was actually a Z80 based 2632 terminal to which a second Z80 card has been added, providing 64 KB of user RAM and a floppy-disk controller. The machine was used as a Z80 software development or general purpose CP/M system. A ROM/EPROM card allowed to develop and run custom programs.

A 300 x 1024 pixel graphics board was also available, including a third Z80A CPU and providing Tektronix 4010 compatibility.

A 2684 was also released, with same features as the 2683 but including a built-in 5.25" floppy-disk drives instead of an external unit.


From Ian Chard (UK):
We had a couple of Cifer 2683s in our student flat about ten years ago. I'm not sure how much I can tell you, but I do remember that the keyboard was much more colourful than the one in your picture. The terminal's bell was a "meep", very high-pitched with soft edges.


Ian Bishop's interesting memories:
I worked for Cifer as a field service engineer during the 80/90s. I had experience of working on all of their 'dumb' terminals through to their Unix 'fan heater' systems.
They had a number of large clients including the Countryside Commission and BLCMP (providing library services to Poly's and Uni's).
The BLCMP version of the 2600 series had a bar code pen attached to the keyboard. It had a seperate board within the keyboard that generated the bar code when the pen was scanned. This was fed to the keyboard port as if you had typed in the code. The pens were always breaking down because the originally used a filiment lamp as the light source. We fitted an upgrade using an white LED which made the far more reliable. The pen tips would wear out though. One version of the pen included a built in date stamp.. A library book issuer could scan a book to a student and date stamp for it's return all in on go !

We were expected to repair to component level on-site. I dread to think what H&S rules were broken when we exposed the CRT on a library counter. Good times though - I did get sick of being taken for a library person at counters by often very rude students. What those staff had to put up with !!!

Cifer also made the 9000 series unix box. It didn't have any keyboard connections and you had to connect a terminal to make it go via a network ring adapter. Up until Cifer being sold off there were several engineers who could service these systems. I became one of the last and used to hold onto the rebuild system that contained all the software needed to rebuild a 9000. The filestore on the rebuild box contained a folder labelled Junta. This is where all the OS Kernals were stored !

The main office/production was in Melksham. I joined the Northwich office - a samll industrial unit. We relocated to Eccles when we merged with another company.
I trained in Melksham workshop when I first joined. We used to receive systems from a sweet manufacturer. To ensure their systems got priority they used to package them in boxes filled with sweets !
Ah the good old days.....

Madeleine adds:
Just to add to this Cifer remains live and well in Wilstire. These terminals are still in use, the 2600 series and indeed the T series, are still maintained on several sites and obviously last a lot longer than todays units!
The colourful keyboards mentionad by Ian Chard were used primarily for the library systems along with British Rail.

Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).

Special thanks to John Ball who donated us this computer !


Is there anyone out there who worked for Cifer???

Many years ago my randfather Gerry Crisp started Cifer with two friends and as the company grew they moved to new premises on Bowerhill Ind. Est. in Melksham Wilts where the company stayed untill it wnt bust. I would be interested to hear from you if you worked for Cifer and so would my grandfather.

Many Thanks

We still use 3 units of Chifer 2683-04-LGB computers. They were modified by MONOTYPE Corporation to support their 272-System. With this system it is possible to make text-layouts and punch control-ribbons for hot-metal composition casters.
The Cifer 2683 computer is the weak part of the whole system. Recently we had to take apart 3 junk machines to repair our units. We always have problems with the display-section.
Is there anybody that could help with spares of these machines?

We had hundreds of Cifer 2634's at the University of Manchester and UMIST back in the 80's. They wern't very reliable and it was my job to do the onsite repairs. This usually resulted in the machine being taken away as they were not too easy to fix.

I seem to remember there were green and orange phosphor versions of the CRT.

There was a guy at Cifer Systems in Melksham we used to deal with for sales. If his name comes up I will post it. I also seem to recall a technical guy who may have been called Don.

We had hundreds of Newbury Data 7007 terminals as well. They were the 'special' versions with many pages of screen memory so you could scroll back and see what the previous user had been doing. The top used to fall off these VDU's leaving you holding the display while the keyboard and main board fell to earth.

What fun.........
