Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

On my maximite (UBW32 + Color MaxiMite adapter by MGB), with firmware v4.1 or v4.2 a strange thing happens:
When you run a Peek: PEEK (keyword, ± offset), with any 'KEYWORD' the video gets dirty with a line.
The background not must be black.







My card is defective or is it a bug?

Maximite is connected to my keyboard, video-vga and sdcard.

While here the mouse is connected via RS-232.
(Save portion of the screen with peek RVIDEO, GVIDEO and BVIDEO)




Can anyone try it?.

Thank, Raros

Doesn't happen on my B&W MM.

p.s. Just tried again in reverse video and I do get something similar. If I run this twice
font#1,,1:For i=1 to 500: ? peek(progmem,i);:next

I get a black line through characters 6 thru 11 on lines 3 thru 9 on a colour VGA monitor.Edited by shoebuckle 2013-01-30

Ah, a bug... and just when I thought that I had squashed them all.

Thanks for the heads up, it will be fixed in the next version.
