The '''Goedhart VisiCom''' is a text telephone for the deaf and hearing impaired that was made by the Dutch company Goedhart Electronics. The general design seems to be from 1995, at least that is the date on the main unit's motherboard.

==Function==
The VisiCom is to be connected to an ordinary computer screen and can be used to transfer text over an ordinary telephone line ([http://en.wikipedia.org/wiki/Dual-tone_multi-frequency_signaling DTMF]) between VisiCom users. As soon as one letter is typed it appears on the other user's screen. It works in a kind of a half duplex mode: only one user ''should'' type at the same time but both users ''can'' type simultaneously. That, however, would result in gibberish. Typing an "X" would tell your communication partner that you are done writing and it is his turn. That's why the X legend is red. The double stepped, red keys on the top of the keyboard are function keys to control the VisiCom's software interface.

In The Netherlands, there is an operator service run by the Dutch national telephone company (used to be PTT, now KPN) that translates messages between ''teksttelefoon'' users and normal, i.e. audio, telephones (used to be Teleplus, now [https://www.kpnteletolk.nl/ Teletolk]). It seems that the Goedhart VisiCom cannot be used with the new Teletolk service.

==Keycaps==
The keyboard's keycaps have [[Inverse cross mount recognition|inverse cross mounts]] and are [[Double-shot molding|double-shot]] except for the red function keys which are pad-printed. There are no [[stabiliser]]s present except under the space bar.

==Switches==
On the inside, there is a large PCB supporting the switches. It was produced by [[DS Keyboard Technic]], and uses [[Printec-DS Sicotast S7]] switches.
