Dit is de "layout" van het nieuwste CoCo videobuffer, gemaakt d.m.v. "SMO" techniek. De werking is identiek aan de vorige versie. Omdat het printje aan de onderzijde geÏsoleerd en vlak is, kan het zondermeer met lijm op b.v. de UHF modulator (blikken doosje) gemonteerd. De zwarte massa draad komt dan aan het blik vast (solderen). Het aan u geleverde printje is voor kleur bedraad en getest. Veel succes met de inbouw. Met vriendelijke groeten, KOEN VAARTJES |
This is the layout of the latest CoCo videobuffer made using SMO technique. The functioning is identical to the previous version. Because the print is isolated on the bottom side and is plain, it can easily be mounted onto the UHF modulator (metal box) with glue. The black grounding wire is then fixed to the metal box (by soldering). The print delivered to you has been color-wired and tested. Good luck with the mounting! Kind regards, KOEN VAARTJES |
