NTSC has a total of 525 horizontal lines per frame, with two fields per frame of 262.5 lines each. Each field refreshes at 60Hz.
PAL has a total of 625 horizontal lines per frame, with two fields per frame of 312.5 lines per frame. Each field refreshes at 50Hz.
The 1084 monitor is NTSC here in North america it wont display the top and bottum of a pal screen because NTSC monitors only display 525 lines. The screen size is the same but on Pal monitors the lines are closer together.
I will be silling my 1960 next week on ebay unless you offer me something resonable. I am up in Canada so shipping may be around $60
NOTE: Just for your info some US communities up until recently were still using a 50hz signwave on the electrical grid and as time has gone on have converted to 60hz as this messed around with the internal clock running slow in computers due to the fact that they use the frequency of the power to keep time. Thats why you still see some companies lable the power supplies with the 50/60hz lable unlike in Canada where it has always been 60hz.
