- TITLE: Ooops! (EXTRA_HALFBRITE not yet!)
-
- It appears that I have made something of a gaff!
-
- My Information Elves (you know them -- they're the "i.e." in
- foo (i.e., bar)) now inform me that the chip rev that includes the
- EXTRA_HALFBRITE display mode discussed in my earlier message is
- not yet in the production line for Amiga computers. The chip in
- question is the custom chip numbered 8362. It is the large chip
- closest to and running parallel to the power supply. The current
- Amiga production runs include revision number 5 of that chip
- (8362R5). EXTRA_HALFBRITE first makes its appearance in R6.
-
- [For those of you who like to get anthropomorphic, the 8362 is
- also known as Daphne or Denise depending upon just how long you've
- known her.]
-
- What this all means is that EXTRA_HALFBRITE mode is not available in
- consumer Amigas at this point. I can guarantee that Amigas produced
- after Q1 1986 will have the necessary chip rev -- possibly sooner.
-
- Apparently what confused the I.E.'s is that a batch of Amigas was
- made with R6's to insure that we hadn't busted something. We hadn't.
- Thus the little guys made the assumption that production was going
- to continue with R6's.
-
- It is to blush.
-
- Meanwhile, my statement that consumer machines handle HAM displays
- correctly is true. This function is also handled in the 8362 and
- works fine in R5. Some R5's were not, however, tested for this
- function back when we were making pre-release machines for developers
- and are not running fast enough to do HAM properly. All consumer
- machines HAVE BEEN properly tested for HAM function along with the
- rest of the battery of tests and burn-in procedures done as a matter
- of course on the Amiga assembly line.
-
- I apologize for any confusion this has caused. The I.E.'s would
- apologize too except, right now, they're hiding under the sofa.
