[comp.sys.amiga.hardware] B2000 - what rev?

I have an early B2000.  It had to have the mod to keep it from eating
the first characters entered after a reboot.  The motherboard has 4.0
printed on it, but I seem to recall someone from CBM saying something
about a version sticker (which I can't find.)  What version do I have?

==>  Dave Haynie - are you listening?

I also seem to recall some mention of some mods to bring the motherboard
up to 4.5 equivalence.  What difference will this make?  What should it
cost?  Are there any other updates that need to be made?  I plan on
adding a 2630 to the system at some point.  What is the current version?


                           Thank you,

As long as this is being asked, I might as well add my two cents:

I have a 4.0 B2000 w/ a 4.2 sticker, my keyboard doesn't throw away the first
couple of presses, but it IS one of the keyboards that will not work with
some (older) games... Here are some questions:

	Will the ECS Chips (Agnus & Denise) work w/o problems in my
	machine?

	Will a modern '030 board e.g., 2630 work ok?

	What are the advantages/costs/possible ways of upgradeing
	to the latest mb revision?

	Sometimes sprites get mangled, this happens mostly on PD games, is
	this a consequence of my machine being old, or is it something else?
	(these same programs work fine on other peoples machines)

Thanks to all,

-->Tony<--

I have exactly the same motherboard as you, as well as the same questions. 
I may have an answer to your sprite problem.  I've noticed this happening on
programs such as Dynamic Studio (sprites for bar count and metronome) and
pointer hacks (only a few).  It seems that this blur only occurs if you've
shifted the screen from where the program thinks it should be.  I use
morerows on an NEC Multisync II so my screen is quite shifted.  If I boot
from Dynamic Studio with their sys-config it's fine, otherwise it's pooched.
 Basically I just had a script copy the sys-config from Dynamic Studio to
system-configuration and switch to that config every time I ran DS and then
back again when I was done and that worked fine.  (Incidentally I don't have
that problem any more...I switched to Music-X :-)

  Unfortunatley I also have a REV 2 A2088 Bridgecard and do wish to speak to
David "god" Haynie about that in E-Mail.  Many problems with it too.  I know
I'm drifting but does anyone else have flaky Bridgecards (ie. a truck drives
by and you have to re-seat it and then fiddle for hours to get it working
again -=>Dave?).  I'm particularly interested to see if the new ones are as
flaky as the old.
