Hi all
Just joined and I already want help.
Couple of years ago got a Z80 machine off Ebay called Rade Watson.
Powered it up and it came on but flickered. STUPIDLY I buinned the monitor that I got with it because I deemed it too unsafe and antiquated. It had been damaged in the post.
Now I cannot get any picture out of it on a monitor.I am thinking that it may be 60hz display.???
It has a 6845 crtc chip to work the display ( which I do not know much about ) and I think that it is a CPM machine as it came with 2 x 5.25 fdds.
Anyone with any info as I am just starting to get back to it and get it working. I think I have determined that the screen ram resides at 4000H after dissambling the 2532 rom.
Thanks in advance
Brian
