| Status | Alpha |
I acquired a old nl:PTT Telecom payphone, type Kimus/Kimas (the name differs, most sources I found called it 'Kimus', but it is stamped as 'Kimas' into the identification plate. I will call it Kimus from now) 2.
It was manufactured somewhere in the mid/late 80's, according to chip dates.
General overview
- Comparable to the German Club Telefon 1. Some parts are interchangable.
- Dialing using both DTMF and pulse dialing, respectively TDK and IDK in Dutch telephony jargon.
- 2 coin inputs on the front, for 0.25 NLG coins ('kwartjes') and 1 NLG coins.
- Amplifier, can be operated using a button on the front
- Separate power supply, 45-60VAC (optional)
Functions
Settings
The Kimus 2 can be set up by a technician using a few plastic 'programming blocks'. Their meaning is noted on a sticker on the inside of the device.
[File:Instelmogelijkheden Kimus2.jpg]
(008 was the former information service)
Translated:
- P1 x 10 = Impulse price (tens of cents)
- P2 x 1 = Impulse price (single cents)
- P3 x 25 = Minimum coin insertion
- P4 x 25 = Internal timekeeping (seconds)
- P5 x 25 = Surcharge per call

I do not know what 'Internal timekeeping' does. I speculate that 'Free numbers' with/without money means that calling free phone numbers requires money to be inserted. Probably to deter prank calls.
Test features
There is a button on the main PCB. Pressing this button will cycle through some test features, described below.
Pictures
blablabla moet dit nog ff invullen obv wiki uploads
Help needed
More info on the technical workings of the Kimus 2 (manuals etc) are very welcome. Romdumps and high quality pictures of the Clubtelefon 1 are also very welcome.
If you are more familiar with reverse-engineering bytecode from ancient MCU's, please get in touch.
I can be contacted at flimpie аｔ bitlair ԁоt nl.
