[cctalk] IBM RT Graphics

Hello! I have an IBM 6152 aka IBM RT system I rescued. (It may be a 6151?) I'm 90% sure it has colour graphics. The system does seem to POST correctly (according to the LED on the front) but the CRT is dead. I'm wondering if anyone has built an adapter to hook this to a VGA monitor. I'm a bit confused by the pinout. It has high and low bits for the RGB (and associated grounds for each colour.) So I'm not sure how that would work hooking to a more modern monitor. http://bio.gsi.de/DOCS/IBM/615x/faqshard.html Otherwise I need a crash course in fixing CRTs. -- -Jon +44 7792 149029
