The Mac Portables did ship with 1.44mb drives, but that doesn't
necessarily mean that's what yours has. I came across one once that had
been replaced with an 800k.

So you actually get a happy Mac when you insert that disk? Have you
tried a genuine System Tools disk?

wait, mine was the ZX81. C'mon guys, let's all sell our computers on ebay!

Service engineer installing an RL02 in top of a mostly empty 50" cab has
it topple forward and suffers injury. Reason, failed to extend and tighten

Two fatal, payment over $25,000,000. Reason, no shoulder harnesses.
Special note: Private pilot didn't have required valid flight review for
that two year period needed to exercise the privilge of pilot in command.
The pilot did not have the required flight time in the previous 90 days
to exercise the privledge of carrying passengers. The purpose of flight
was commercial photography (private pilot cannot hire out). The plane
was modified illegally and improperly to mount a camara for the purpose of
the flight was the cause of the loss of visibility for the pilot. The FAA
issued in 1978 a directive that all aircraft will have shoulder harnesses
installed. Despite an illegal operation, non complying pilot and aircraft
an excuse was found to force libility on the manufacturer of the plane of
some 40+ years age.

Well, I made some progess with the Mac Portable today. Although I still
don't know what the Sad Mac code $0F means (all the FAQs that I've read skip
>from $0E to $10).
Here's what I've found:
1. The portable won't accept a 1.44mb disk created with a PowerMac
but that contains System 6.0.1 (I get the disk with the "X" in it). I
thought that the drive was a 1.44mb disk.
2. It will not accept a 400k disk.
3. It will not accept an 800k disk formatted by an SE/30 which
contains System 6.0.1.
4. It *will* accept an 800k installer disk, but it complains that the
disk contains a "minimal" script file, and that I need a "full" install
script. Arrrgh...

I still don't get it. Anyway, while we're on topic, has everyone
heard that the U.S.S. Yorktown's NT system crashed, causing it's
engines to fail and forcing a towboat to pull it back to shore?
The Navy is considering installing more NT systems; they won't install
UNIX due to some protocol, not sure. Check www.osnews.com/news for
the link to the story.

This is slightly different. It is difficult to see spinning blades,
and people in third world countries who aren't used to helicopters
are known to injure themselves, not noticing them. Especially if this
was the same guy who drilled his brains out :) I assume you've all heard

Not really. the trick used in 9900s is to use load to start a rom based
program that copies itself to where ever needed and then turns itself off.
The way I'd do it is to put a small rom at F000h and ram where the old roms
were. The old rom can then be located at D000h with only a few bits (one)
needed to turn off the old roms and the boot room. I do this all the time
with Z80s to get the system totaly ram based but with the advantages of rom
start up/restart. The trivial trick is to make it seem invisible. the big
advantage is if you want to use the memory for something else you can but
makesure to do a relod if you want things back to normal.
I recently got an extra console that will be modified so that a pair of
32kx8s will map in to where rom, and 32kb expansion ram would be.
IE: 0000->3fffh and A000->FFFFh. using 2 32kx8s keeps the chip count low
even though 50% is wasted, besides they are cheap. The effect is the
system could be much faster as it does not need the PEB access for base
ram.
I may want to yuse the full 64kb of the pars so I need to know how one of
the larger cards like the corcomp 512k map. Do they do it as if it were
multiples of 32k or are the two segments (2000->3FFFh and A000->FFFFh)
mapped seperately or is it done in 8k segments?
< Just a little FIFO would work well, but then, if the CPU bottlenecks

Not really it's a matter of buffering the data and post processing it
when the tide slows or issueing an Xoff/suspend to stop the flow before
the buffer overfills. This situation is nothing new, though in the world
of CPU with clocks in the UHF region people may forget that. However the
problems of data arriving faster than it can be processed is old hat.
Besides with a ramdisk buffering a few kb of data is nothing.

Okay, for me it's easy: <http://www.sinasohn.com/clascomp/> 8^)
Not listed is a "101 California" terminal, a Zenith keyboard terminal,
Fujitsu Stylistic 500, Everex 386 Laptop, and the 128K mac, Altos 8000, HP
3000, HP 9000/310, and hp9000/345. Hmmm. And the odd 8-bit atari, and the
MSX machine, and a few others that don't really fit into my collection.
So, it's a little over 100, of which 80+ are portables.

Yes, I find that very odd too. The address lines, page selects, and R/W
signals on the 1MHz bus are unidirectional (direction: out of Beeb) so
about the only things the Graduate could control would be the NMI, IRQ, and
analogue input lines.

There was never a Tandy 4 Meg card. Bob Snapp had boards to take a 16
or 6000 up to 8 Meg, but the memory management permitted only a max of
1 Meg "user" RAM -- the rest could be used as RAM disk, permitting a
/dev/swap far larger and faster than Tandy hardware. It was damned
impressive to see his stuff at the Tangent conference in Fort Worth in
1986, 15 terminals (plus console) filePro databases faster than a stock
system could with three users.

Actually, except for the 6000HD which would only accept one external
drive after the internal, all hard disk subsystems for the Model
II/12/16/6000 line would permit four external drives, either all 8.4
Meg (the 8" Shugart "original" system) or any combination of 5, 12, 15,
35 or 70 MB (the later 5.25" system). At least that was the case with
official Tandy hard drives.Those latter would also attach in quantities
up to four to any of the Model One/3/4 product line or the Color
Computer. That's what always surprised me when PCs and compatibles
were limited to two drives, at least until SCSI and EIDE.
