Is anybody out there using a monochrome monitor on their 1000 to overcome the flickering interlace problem? I have a need for the larger resolution, and I can sacrifice the color. What monitors are good for this? How to connect? What fonts are good for 640x400 monochrome, etc? Please respond via email. Thanks! -mike Mike Landis, Dept. of Computer Science, Duke Univ., Durham, NC 27706 ARPA: mdl@cs.duke.edu CSNET: mdl@duke UUCP: decvax!duke!mdl

I'm using a Magnavox Computer Monitor 80 (the composite one, not the IBM TTL one), heavily overscanned (704x480, or something like that). It works great with an Amiga 500 or Amiga 2000. However, a monochrome monitor has problems with the Amiga 1000. Color signals introduce cross-hatching, due to the chrominance signal impressed upon the luma. If you run a grey-scaled workbench and set up all your software to run grey-scaled you can get around this, but some software doesn't allow changing the pallete on their private screen. Also, it gets hard to find the cursor in greyscale on a 704x480 screen when you have an editor window filling most of it. An orange cursor at least gives you something outstanding to search for. But you'll probably run with white text on a black background, with the cursor greyish, and there's a heckuva lot of text to look through to find it (83 chars x 52 lines or so). -- | // Eric Lee Green P.O.

That would be kind of fun? I remember Richard@gryphon mentioning A-A fonts, and Tom Rokicki even built some, I think. Whaddya think? Can we have a mono-amiga with pretty anti-aliased fonts? Sort of a cheap NeXT look? ron

Sort of a cheap NeXT look? NeXT doesn't have anti-aliased fonts; just the other features you mentioned (2-bit gray scale and high (92dpi) resolution). Ali

Sort of a cheap NeXT look? ^^^^^^^^^^^^^^^^^^^^ Contradictio in terminis ? I haven't seen much usable examples of anti-aliased fonts yet. And I certainly wouldn't impose that on an Amiga with a 2024 greyscale monitor. For anti-aliasing you need at least 100 dpi if you don't want to see any individual pixels and maybe 16 greylevels. Any idea how your blitter will think about that ? Tom van Peer. tom@pcg.philips.nl or dinsdale@liaison.sun.com (whichever is closer to you)

And I certainly wouldn't impose that on an Amiga with oh, well, i guess i blew this one. I still want to try the mono with MoreRows. It sure ought to make AmigaTex look pretty nice ... I wonder where all the original info about NeXTs use of anti-aliased fonts came from? I haven't seen it, i was going by what I have heard on comp.sys.next ... Shoot. ron

I recently purchased a Kraft 14-inch monochrome monitor for my
Amiga, but I can't seem to get it to work correctly. The monitor
has a db-9 connector that looks like this:
CGA TTL
1 - ground ground
2 - ground ground
3 - digital red reserved
4 - digital green reserved
5 - digital blue reserved
6 - digital intensity intensity
7 - reserved video
8 - horiz. sync. horiz. sync.
9 - vertical sync. vertical sync.
It is obviously a dual-mode monitor. I made a cable that
(supposedly) connects the Amiga 1000 up to a CGA-compatible
(RGBI) monitor, but no-go. The machine boots, but the screen
never even shows hints of light. I know the monitor works
on a monochrome PC, so that's not the problem. And it looks
incredible since it's built for interlace, so I'd really
like to get it to work with the Amiga.
Does anybody know any reasons why it might not be working
for me? I would really appretiate any help that anyone could
give. Thanks alot. -Mike
