Re: First Television to use ICs
Yes - the CTV174D proudly proclaimed "IC Colour Lock" on the front panel!
The SL901 originally used was mounted on the 'wrong' side of the decoder panel and had the heatsink horns coming out of it. Pre solder wick, most panels were badly damaged when someone had used a 50W Weller to remove it.
The power supply, IF and timebases were pure CTV25/162 Mk3, but the decoder and output (now RGB and transistorised) panels were completely redesigned. I wondered if the use of the SL901 was to road test the IC before using it in the A823?
