I recently came into possession of this PC:
I haven't been able to find much about this PC, only that it is a 100 % IBM compatible PC running at 7.16 MHz.
Apparently, there is a switch somewhere to select turbo mode and normal mode (haven't found it yet 😀).
This PC also has a colour monitor (model 3584-01), which is one of the main reasons why I bought this PC, since I've been looking for a colour CGA monitor for a while now.
However, when I power down the PC, the monitor displays this image (I then have to also switch off the monitor):
Is this "normal" for an older monitor of this type?
If I let the PC stand for a while (say a day or two) and then power up the PC, the monitor initially has some "jitter" which then stabilises as it warms up.
What could be the cause of this and how must I address this?
Any other information about this PC is appreciated (manuals, documentation), etc.
