Another nifty hack, Leo, though not as perverse as usual :-)!

Hmmmm ... and by my count, two versions of "munching squares", Matt's
DME v1.27, and some stuff I've submitted (ushow, scnsizer, etc.)
Hello doc ... are you there ...
And now to the real point of this posting ...

3.4b? b? Has Jim released the new version? The Manx support BBS has not
been answering for several weeks now, so I am not up on 3.4b's progress or
availability. How's it look, Leo?
BTW, dunno if this is a compiler problem or a "feature" of EHB, but if
the "dancing square" is at the top of the screen when you click the RIGHT
mouse button, it'll take a bite out of one of the upper rectangles ... can
sorta make a game out of it! Hmmm ... maybe EHB *is* as perverse as your
other stuff ... :-)

(which I forget off hand). The README file also says that the version I
have is preliminary. Every bug that could be fixed has been fixed. This
implies that there are still a few limitations, but I haven't bumped into
them yet. Jim says that it should be out Real Soon Now.

An artifact of using the screen's RastPort and not the window's.
When you hit the menu button, Intuition LockLayers() all the windows,
putting to sleep any task trying to render to them. However, the screen
RastPort isn't connected to a layer, so it just happily keeps drawing away
all over your menus and menu bar. This isn't something you want to do if
you're writing a "serious" program.
The reason I render into the screen RastPort is to gain a little bit
of performance. Windows are a superset of layers, which have clipping
routines attached to them. Drawing through a clipping routine slows things
down a bit, which is why I bypass it. So sue me.

I didn't make it to BADGE last night, but the pass along is that Jim has
bundled-up v3.40b, and shipped it off to Manx for release and distribution
(last week).
Also, Steve Walton tells me (about the "bugs"):
+ that is, those which aren't fixed aren't
+ really bugs but rather non-ANSI interpretations of syntax in the front
+ end which will remain until version 4.1. Some mysterious libraries
+ with "i" as their middle initial (i.e., mi32.lib) turn out, according
+ to BIX, to be for handling those 68881 add-ons which treat the chip as
+ an I/O device rather than a coprocessor. I'm told the Starboard 2
+ MultiFunction Module falls in this category.

Naw ... much more fun to try and "eat up" the entire horizontal bar :-)!
BTW, I hear Viacom is pretty slick, Leo (or did he say "sick" ?) Hope doc
will get it posted pretty soon ... I hear he's having "mailer problems"
again (sigh)!

After encountering three machines without EHB, I asked Dale Luck at
the last BADGE meeting what his estimates were on how many Amiga 1000's have
EHB capability.
He guessed that the current percentage of Amigas with EHB is about
10%. I suspect it's a bit higher. His explanation was that there was
indeed a new rev. of the chip which made it into the first thousand or so
production machines. Then Commodore started using an older rev. because they
had about 50K of them laying around and didn't want them to go to waste.
Assuming 50K machines without EHB, and 150K machines in place, I
suspect that percetange is more like 66%. Hmmm. Oh well, that's why I
cooked up the 'ehb' program - so you could find out.

Extra-Half-Brite mode on their Amigas. Everyone having an Amiga and
reading this forum is invited to participate in an informal survey...
On xanth (specific addresses below), I have created two aliases:
amiga-ehb-yes -- meaning: "Yes, I have EHB"
amiga-ehb-no -- meaning: "No, I don't have EHB"
Run Leo Schwab's EHB test program (from <33...@well.UUCP>). Then...
If you DO have EHB mode: send a letter to "amiga-ehb-yes".
If you DON'T have EHB mode: send a letter to "amiga-ehb-no".
*** DO NOT MAIL YOUR RESULTS TO ME! YOU MUST USE THE ABOVE ADDRESSES! ***
(This means you should *not* reply to this letter to vote!)
In a few days after sending your letter, you should receive a response
confirming its receipt. The letter itself is not read by anyone, so
the Subject: and body should be empty.
After not receiving any new responced for a week, I'll post a summary.

conducting a survey of how many USENET readers with Amigas have EHB.
The votes have started to come in less frequenty, so I thought I would
repost the instructions again to catch anyone I might have missed or
to remind those who forgot. The aliases immediately send a response
to every vote they receive, so if you never got a response, try again.
(I've had a few mailers choke on the replies, but I think I was able
to reroute those around the bad mailers). -- tad ]
