SBC6120 with a teletype

Recently I bought a Teletype (a Texas Silent 700 model 703), it is special as it uses thermal paper and it is surprisingly silent :-).

I installed the light guides on the SBC6120 indicators, so now they are much more visible.

I had to replace an internal dip-switch and find a power supply for it, unfortunately I could not find a suitable power connector, for now it is connected with a pair of crocodile clips. The power input is AC-Earth-AC and a suitable voltage is from 20V to 26V, the current is about 1.5A.


The serial connection is at 300Baud surprisingly slow... 30 cps... This was how computers were operated before there were VDU (or CRTs as you prefer), it is very interesting. Next I'll try to install the Adventure game... The serial cable that came with the machine had to be tweaked in order to make it work with the SBC6120.


Here is a clip of theSBC6120 booting connected to the TI Silent.
