Another Electronic Teleprinter for the collection

Seems I have another machine for the collection

This is a BT Merlin Super Cheetah.

I have all the original documentation, and service manuals, and this is a complete system, Keyboard, and printer

Works on V.21 for line connection, so I need to figure out how to get this onto I-Telex

It's a pretty soulless thing, but nice to find a British Electronic machine that might just work.

The PSU is full of lovely Rifa Dragons, so there will be little testing until I have replaced these.

For I-Telex you will need a modified analogue modem board.
Not to throw away the unfortunately now useless modem boards we modified them for use as V.21 teleprinter ports. But only one port per board.

Power supply now out on the bench - given the relatively small number of capacitors on this supply, I will replace all of them, some of the electrolytic units are showing signs of distress, with the tops noticeably bulging.

Hopefully this will make the supply reliable for another 30+ years.

The back up battery for the memory had not been removed prior to storage - this is a problem, they have leaked and have contaminated the rear of the main PCB, as well as caused some corrosion of the communications sockets to the rear of the machine - this will need some careful cleaning to stop any further deterioration.

More pictures to follow later today

That doesn't look like a telex machine anymore, more like a PC! :suspect: ;)

hi Rainer,

Yes, it is very similar to a PC, the design is quite close, but the electronics are certainly not :)

I cannot post too much here - Henning will ban me for lack of gears and motors :)

No worries Sean. I am curious if the machine has got a printer at least. :)

Hi Henning, yes, this machine has a printer - As soon as I have the power supply board finished, I will post some better pictures of the complete system.

Hi Sean,

nice teleprinter. The monitor looks like an old qume terminal.
Is there a microprocessor in the teleprinter or has the system special integrated circuits like in the siemens t1000 teleprinter ?

Please provide more photos. ^^

Regards
Thomas
