Thanks for that info. So I wont panic about the 1 hz difference. I've got an old microbee amberscreen monitor I've been meaning to hookup and I might try that today. I'm assuming they're ] chars but they are a little blurry, could be ?'s . The original RF Modulator is dodgy so i've hooked a new one up and this produces a very black screen with little noise. The orignal is a snowstorm.
How do you turn on test mode? I don't know about that. I'm curious. Is it a dip swtich thing? Mine has 48K RAM and I just took delivery of an entirely new batch of 4116's to replace them if they are faulty. Chances are they may have been zapped over the last 20 years. I wonder if the Char Gen chip is OK.
It's been a while since I looked at the dip switches, Can you remember what the correct settings are? I have 48K RAM with BASIC in ROM.
By the way, can you see the yahoo group?
The screen wiggling is normal because the vertical frequency is about 49 hz and it beats with the 50 hz of your tv, creating a 1 hz disturbance. The only way to get rid of it is to use a good quality green-screen monitor.
I'm not sure about the ] characters, never seen that before. What happens if you turn on the test mode?
I am near Campbelltown.
How much RAM do you have? Are the dipswitches set properly?
