Sitenotice: 11/29/2018: The wiki is back. It turns out, some anti-virus product on my web server had an issue with the latest version of PHP. My server techs have resolved this issue, and things should be working again. During the investigation, I did restore to a backup from September. There is a chance that any changes done since then were lost, but I do not recall any edits. --OS-9 Al

8/30/2016: Massive re-work is being done on the InfoBox Templates. Read that page to keep up with the plan for that, and adding better keyword tags (categories) to all the pages. --OS-9 Al (talk) 15:28, 31 August 2016 (CDT)

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
