I don't know much about this either.. but since the schems specify +5 for the mono pinout I would assume it needs it? For either mono or color you might as well hook it up.

I would probably just try to dig up a CGA monitor and see what happens.. might as well go color since you have to dig up a monitor anyway :)

I finally set up my bench again this week and started messing around with the 9100s again.. but I havnt been doing much other than assigning RAM & ROM sig refs for a few games..I don't have a TL1 manual or programmers manual handy.. I think Chris L still has them, I gave them to him to scan many moons ago.. Is the TL1 manual online anywhere?

I ran through all my Star Wars PCBs the past 2 days.. I was pulling the matrix PROMS and just checking them in my 29B.. I would guess there would be 2 ways of testing them on-board.. A script that writes blocks of the PROMs into MBRAM and then verifying them there, or using an I/O pod and grabbing a sig.. I have a big stack of Asteroids boards on the que as well, I guess its the same story with the state machine PROM?

So after fixing 6 main SW pcbs.. I go through the AVGs and out of 8 of them, 5 have bad custom address controllers.. grrr... Anybody have any SW sound boards? For some reason most of mine are missing :(

Must the monochrome be optoisolated & power the Video card with +5VDC or can I use the CJUMP & run a monochrome monitor?

What is Intensity voltage level/range normally on a monitor? (I'd like to use a non Fluke monitor)
