  • Plugging a monitor into a speccyI have a Philips CM8833 MKII with built in speakers and wanted to know can i use this for a spectrum and if so how would i go about it. thanks

    The CM8833-II does NOT have a VGA port. A lot of them have a DB9 that accepts RGB. There are lots of models of the CM8833, so it is hard to be specific. I would get a composite mod on a spectrum and use that.
