ST 11:30 PM EclaireXL Bug #52 (Closed): Atari Control Picture

CORE14, PAL & NTSC exhibit the same behaviour. When displaying the attached Atari Control Picture, the colour blocks in column 0 are only displaying the rightmost 4 pixels, not the entire 8.

Yes, everything on the ATR I attached works. I will attach the version of Veronica BASIC I was trying to use. This evening I will arrange my desk better so that I can... Stephen

ST 02:40 AM EclaireXL Bug #48: CORE13 - Veronica BASIC not working

OK - I got the rotator demo working. However, I cannot get Veronica BASIC to load. It either hangs or says it cannot communicate with the cart. Pressing F10 causes my monitor to see the input switch, but I get a black screen, and have... Stephen

Guys - I am very sorry. I was not loading the BIOS first. Veronica is working properly. I tried to delete this, but must not have appropriate permissions.

ST 02:14 AM EclaireXL Bug #48 (Closed): CORE13 - Veronica BASIC not working

I've tried various RAM and NTSC/PAL settings. When I run "detector.com" from the attached ATR, the screen flickers and I get "Veronica Not Detected". My Veronica is a black cased Revision 2.0. Stephen

ST 02:18 AM EclaireXL Bug #50 (New): CORE13 - Option on initial powerup does not disable BASIC

When initially turning on the Eclaire, holding F8 does not disable internal BASIC. However, once booted, if I hold F8 then press F10 to restart, BASIC does get disabled. The built in self test shows the keyboard is responding. Stephen

ST 02:17 AM EclaireXL Bug #49 (Closed): CORE13 - NTSC/PAL switching

I've noticed several times when I switch between PAL and NTSC, then do a "save and apply", when I exit, and exit the main screen the core has frozen and no keys respond (F10, etc.) It doesn't seem to matter if I go from PAL to NTSC, or ... Stephen
