To add my wee bit 'o wisdom...

The 1:1 interleave of the afor mentioned LaCie drive probably indicates 
caching being done inside the HD.  Most HD I see connected to Pluses are
2:1 or rarely 3:1 interleaved.

Only one brand of HD did not initially work with a PLUS.  That drive would
act as a System (startup) Drive for all Macs but not the Plus.  The manufac-
turer (need not be mentioned) stated, upon phoning, 'send it back for ?PROM?
replacement.'  It worked upon return!  The problem was an incompatibility
fully acknowledged by the manufacturer. 
  
 I suspect that 'lots of errors' in using a HD might be driver related?  The
HD in my PowerBook indicated *total failure* at times when working with Silver-
Lining but okay with Apples HDSC setup formatting...  Soon after the PB internal
hard drive died.  So 'lots of errors' in this case might have been an early
indication of hardware problems.  (An intelligent person might have RUN to do
a full backup - but not ME.  I lost much of what was on the drive.)

The dealer probably didn't have any. I ordered a PB145 direct from Apple
on August 4 (they started taking orders August 3). I received it via
FedEx on Wednesday (two days ago, that's about four weeks). 

Apple usually takes a while to get machines out into production. Two
weeks ago, I doubt they had many (if any) 145's.

I have installed several of these systems and use one myself at home with
System 7. The reason I went for this was because of the quality of the
screen as I observed it at MacWorld Expo almost two years ago. The quality
is almost as good as Apple's own monitors and better than most 3rd party
monitors. The accelerator speed is noticibly faster than a stock SE and
maybe even faster than a Mac II. It's hard to say. Theoretically it should
faster than a Mac II but I think there are architechtural differences which
may hamper the Mobius. In any event, mine does not have a math coprocessor
or PMMU.

Most software runs fine on it--certainly Word 4 & 5, Excel 3 & 4, MacDraw
II, THINK compilers, telecommunication programs, etc. Notable exceptions
are programs that use sound. The sound routines in the SE ROM does not work
right with accelerators. Mobius knows this. It can cause my Mac to crash.
So I turn off sound and just live with it.

Would I do it again?

Maybe. It's cost effective, for sure, and I could not have gotten anywhere
near the package in an upgraded system for anywhere near the price. (sell
the SE, buy a IIcx, monitor, etc.) However, I feel the limits of 4MB RAM
and no color QuickDraw.

Be careful with this advice on picking up LC VRAM for a Quadra.
This only works for the 700 and 900 but it will not work with
the 950. The 950 requires faster VRAM than the 700/900. (I'm
sorry, but I don't remember the speeds in either case. I think
the LC had 100ns and the 950 requires 80ns, or was it 80ns and
70ns, respectively?)

If you want to lose lots of money, then it is a good idea to do

  Bob, what is probably happening is the dreaded 'memory effect' common to
NiCad batteries.  If the battery is not fully (or at least close to it)
discharged before it is recharged then a "memory barrier" is created at the
point where the battery started to recharge.  Thus the amount of charge
that a battery can take is reduced, and the batterie does not last as long.
 The best thing to do with these type of batteries in order to get the
maximum life out of them is to run 'em right down to where the "10 minutes
of power..." dialog comes on, then put 'em the recharger and let them
charge all of the way.
  Unfortunately once the barrire is there I don't think that there is
anything that you can do to get rid of it.  Also the projected life span
for the Apple batteries is only about a year anyway, so yours could just be
getting a little little long in the tooth.

  What I did for my 170 was to buy the Battery Charger/Conditioner from
Lind Electronic Designs out of Minneapolis.  This charger will fully
discharge the battery and then fully charge it.   With this I've been able
to get 2 - 2.5 hours of useful time on a PB 170 with 2Mb of RAM and 10MB of
virtual memory running MS Word 4.0.

The new EtherNet card is a better card then the old EtherTalk card. It has
an onboard CPU that offloads some network functions from the Mac to the
card itself. As such, it requires the A/ROSE System Extension which will
be installed when you use the Network Installer disk that comes with the card.

However, under A/UX, the CPU offloading capability of the card isn't
used at all. The new card has a larger buffer (64k vs. 16k) so that helps
out a bit under A/UX.

The EtherNet card uses Apple's "standard" ethernet connector (the same used
for the LaserWriter IIg and the Quadras) and requires an ethernet "adaptor"
to convert from it to whatever-your-net-uses... the cost for this adaptor
is about $100!

Not really; it's true that it takes longer to draw when you
draw into a lot of colors on the screen, but if you set the
screen back to the depth it was before; you get the same
speed you had before.

You get the option to use more colors at a slower pace.

   With a 512k VRAM you get 256 colors on a 640x480 display (13" Apple RGB), or a
   zillion (<2 million) colors on a 512x384 display (12" Apple RGB). So you in
   fact do need this SIMM for 256 colors on a 640x480. The 256k VRAM only gets
   you 256 colors on a 512x384 display.

You don't get zillions of colors; you get 32768 of 'em (15bit)
The LC internal video cannot produce 24bit color (millions)
However, QuickTimes native format is 15bit color, so the LC is
actually not too bad as a QuickTime player - especially if you
add a 040 card...

Numerous times in Inside Macintosh it is documented that the input
handshake on the Macintosh serial ports is also the external clock pin
and is connected to the *TRxCa and *TRxCb pins on the 8530 SCC. 
However, nowhere can I find out how, after connecting some neat clock
signal to this pin, to tell the SCC to use the external clock rather
than the baud rate generator.  This could have something to do with the
fact that I don't have any 8530 documentation (does anyone know how to
get some?), but I don't like the idea of directly playing with the SCC
chip itself, especially because of machines like the IIfx.

So, is there some secret _Control call that can be made to the serial
driver to tell it to do this, or if not, what bit(s) of what register(s)
of the SCC do I set/reset to use an external clock?

Any information or help is appreciated.

Thanks,

p.s. If it helps, I'm only trying to get a baud rate of 115,200--
