	I talked to the the Mobius reps and Daystar Digital folks while
at MacWorld Expo last week and both said that their versions of the
40 Mhz 68040 cards won't be out until sometime in 2nd quarter '93 - both
companies are waiting on Motorola to deliver this cpu in quantity.
	At the Daystar Digital booth, I noticed their 33 Mhz '040 card
had a daughter card plugged in, and after asking a rep, he confirmed it
was their 128K cache card.
	I went back to the Mobius booth and noticed that their card had some
unoccupied sockets at one end. When I pressed a Mobius rep about this,
he verified it was indeed, a place to hang a 128K cache card, along with
possibly "other things". He wouldn't reveal what "other things" were, although
he bragged that their card had more lines and more controlability than
the corresponding Daystar Digital card. The cache card would go for somewhere
around $300-$400. I'm guessing it might be some sort of high speed coprocessor
or QuickDraw accelerator, or even a compression daughter card.
	Other observations...I asked the Mobius rep how many working 40Mhz
'040 cards they had - he said 1 (I'm pretty sure that's what he said).
I guess that's all the prototype cpu's they could get from Motorola. Also
the Mobius rep said that for the first 6 months of its delivery, the card
would come with a socketed rom, so firmware upgrades would be possible by
shipping a software patch combined with a new rom. The Mobius card had
2 or 3 ASICs along with a couple more chips. The Daystar Digital board
had a bunch of PALs on it. I guess this is just different design philosophy.
	I didn't ask about AUX compatibility for either manafacturer.
	I'm going to take a wait and see attitude and I'm anxiously awaiting
any magazine reviews which tests both companies 33Mhz card, since this will
give a good preview of both companies 40Mhz version.  BTW, the Mobius ad
in MacUser magazine lists the price for a 33Mhz Speedster 040
as $1299 (with FPU). At the Expo, ComputerWare was selling the Daystar Digital
33 Mhz Turbo 040 for a Mac IIci for $1499 (srp of $1599). The cache card
for the Daystar board was selling for $379 ($399 srp).

Subject: SE Sad Mac -- ROM Checksum?

Keywords: SE ROM CHECKSUM REPAIR
Organization: SQ Software via The World Public Access UNIX, Brookline, MA
Date: Wed, 13 Jan 1993 04:39:22 GMT

Hi foks,

I have a Mac SE which on powerup gives the following Sad Mac error
codes:

00000001
0000FFFF

I've been under the hood and I disconnected the SCSI disk and the
Floppy drive to try to isolate things.  I then swapped the RAM SIMMs
with fresh ones.  I then removed the ROM chips from their sockets and
reseated them.  It consistently gives the same error code on powerup.

My understanding is that this indicates that the Mac failed the "ROM
Checksum" test.  I'm wondering:

1)  How likely is it that this indicates a bad ROM chip?

2)  Any recommendations on where I might get the parts to fix this
problem? 

3)  Failing that any recommendations on where I might get someone else
to fix this for me?

I've seen some ROMs for some mac's available through mail order.
Anybody have any experience with this?

Thanks,

Yes, the HP LJII does have both of these, and an optional I/O port as
well; however, not all are active at the same time, and you have to
manually switch.

Well, excuse me all for asking what appears to be a blatent FAQ (indeed, as 
one person bemoaned, they should include a note about it with the monitor).

But this seems like a really stupid design flaw, what is the justification for
it? I know I will probably cease to notice it soon, but why have it at all?
Not all monitors have this problem, especially the VGA for IBM's. In short--
what's so damn great about Sony Trinitron's that justifies the line(s)?

  There is no socket for a FPU on the 160, but Dynamic Engineering will
piggy pack one (I forget the cost).  Their number is 800-487-4655.
Conisder your warranty void if you do though.

  The Duo 230 doesn't have an FPU, by the way.  The 170 is a serious 
option though...

I've been having fairly severe battery life problems with my
PB100---I'm only able to get about 30 minutes of life from the
battery.  

I would simply think "oh I need to buy a new battery", but the machine
isn't very old, and I would guess the battery has seen no more than 40
to 50 total discharge-recharge cycles.

I would be curious to hear if other PB100 owners are experiencing
similar difficulties.  Do I have a faulty charging circuit in the PB?
It does charge the battery at least somewhat in that I do get a
half-hour of usage.

One possible additional factor:  for a couple months, I didn't discharge
the battery at all (I just used the machine on my desk and left it
plugged in all of the time).  Will this kill a battery?

Thanks,
Fred

In Apple's 1/6/92 press release on the new workgroup printers, there is the
following statement:
 
>>>>>
As a special introductory offer, Apple will ship the LaserWriter Pro 600
with 8MB of RAM, enabling users to take advantage of 600 dpi resolution and the
superior grayscale printing capabilities of PhotoGrade.
<<<<<
 
I just visited two Apple dealers who were completely unaware of this offer.
Both of them thought that the LW Pro 600's that they had in stock were shipped
with 4MB, and they had no paperwork describing how to obtain the additional
RAM.  Does anyone know what is going on here?
 
OK, let's now assume that if I buy the LW600 now, I do get the additional
4MB RAM.  Is this the same as the PhotoGrade upgrade kit (M5861G/A), or
do I still need that kit for PhotoGrade or 600 dpi printing?
 
By the way, the new Apple Lasers look like very slick machines.  A couple of
months ago, I was ready to pop for the LaserWriter NTR or the T.I. microLaser
Turbo.  A little voice on the net whispered "wait a few weeks," and I'm
glad I did.

My friend and I each got a spare battery and a floppy bar from 
ComputerLand of Delaware in their going-out-of-business sale a couple
of weeks ago. (My friend actually bought his 210 there at the same time,
it was $100 more than educational, but the lack of sales tax made up
the difference).

I have not however seen the floppy drive itself, or the minidocks, yet. I
am using the system with the floppy from my 100. I sold the 100 to another
friend who doesn't need the floppy (he is using it as a library-trip machine
and offloading over apletalk to his quadra.).

If anyone sees minidocks please post!

Now my big question is why-o-why did e-machines decide to not pass through
the internal modem port on their minidock?  I called them and they said
"Well, we figured that when you are docked, your on a network, and you have
access to a big fast modem on yournetwork".  I can't believe they assume
every docked duo is on some giant net! What morons.  It would have cost them
about $0.50 in parts to pass through that port.
