Indivision AGA A1200 issue
« on: January 23, 2010, 03:09:32 PM »
I just acquired an Indivision AGA A1200 scandoubler with firmware 1.20 (dated 10/2008).  I installed it without incident and booted up my A1200 that had previously been using a different internal scandoubler, which I removed.  Workbench under OS 3.9 had been running at dblNTSC, I believe - noting too odd.

I got the Individual Computers startup screen, but then nothing - just blackness.  

I rebooted, holding both mouse buttons down and got the boot-menu displayed just fine.  I then proceeded to boot -- still nothing on screen.  I rebooted again back to the boot menu and booted with no startup sequence and got the shell fine.  I ran a few demos - display looks good.

I've tried various boot scenarios to try to get fully into workbench, but it's never worked - and along the lines, often, the machine will just stop putting out a video signal.  I will boot into start menu and can tell that the menu is there from the sounds of the machine as it goes through its boot process, but still zero video signal (different from black screen) -- only a power cycle will put me back into a situation where the board does as described at the beginning here.

Does the Indivision have these issues for most folks?  Any way I can edit the prefs from the shell (no startup sequence) so my HD boot is into some "easier" res -- not that dblNTSC should be a problem.

Ideas?  Thanks.

(I will say that, to my eyes, what I _have_ seen of this board in running demos is a lot nicer looking than the scandoubler I was using previously, somehow. Oh, I'm running a 19" Sony CRT, btw.)

CSG chips here.  It grabs fine.  Like I said, if I cycle power and start over with the double mouse button, I get that screen, so it's not like it's not connected.  

Having trouble finding the drill to upgrade firmware via google. Can someone point me? Also, we might be in a catch 22 on that one.

As far as LoadWB, when I do that after boot with no start, it loads, but no prefs will run - an issue flashes in the title bar faster than I can read it, in repeated attempts.

Tnx.

UPDATE: Oh wait, it seems my Lisa is HP but Gayle and Alice are CSG.

Still, it seems to grab well and I don't believe there's an issue with contact.

Thanks guys.  I got the prefs changed to dblNTSC and that boots just fine.  Flashed up to v1.5 firmware.  Then moved to HighGFX, which works fine, but has those glitches everywhere, as many have reported.  Odd.

Is it me or does this seem to do a better job than a couple other scandoublers at just typical scandoubling PAL?

Still, every so often it stops doing signal at all on reboot, and I have to reboot a few times to get the signal back (w/ v1.2 had to cold start).  Dunno.

Well, I am using this with a Sony 19" CRT (circa 2002) - so many of the issues you list re: LCDs drop away.
