When you do a dir C: can you read what was originally on the hdd prior
to the upgrade attempt? If so, try booting with a DOS 5.0 boot
diskette which contains sys.com in A:, then copy command.com to C:
and do a SYS C: from A: as well. This might get this system bootable
again. On the other hand, if you can access your original data, now
would be a good time to back it up. Good Luck.

We just gave a teacher a Magnavox Headstart 486SX PC. It has a large
yellow sticker on the back that reads "DO NOT FORMAT THE HARDDISK". So
what do you think he did? :-) Tried upgrading DOS. (5.0 > 6.2)
Dos says, "Wanna format the harddisk?" User says "OK, Whatever..."
Now we have a dead PC. It will boot off the floppy, it will do dir C:, but
it refuses to boot from the harddisk. I'm thinking they hid something
proprietary in the bootsector. Anyone else know anything? We have no docs
for it, but there's another PC like it in the building somewhere, I have to
go find it... Would it fix my problem if I were to get the partition
table off the other (good) machine and write it to this one, would that fix it?
We already laplinked it to another Magnavox Headstart and tried transferring
everything back, that finished OK but still won't boot. I'm getting ready to
hand the guy a bootdisk and say "Here, you have to boot from that..."

The Grappler/Grappler+ thing came to mind, but I came across a
Grappler+ a couple of months ago, had the presence of mind to note it
as such in my inventory, and don't remember there being any obvious
RAM on it. That probably says more about my memory than about any on
the card though, and I can't remember whether the Grappler I had in my
old ][+ was a + or not, just that it didn't have RAM. Whatever it is,
it's a parallel printer interface.

Huh? The necessity was that there be some way to hook a ][ up to a TV
set, because not having to buy a monitor kept the overall cost of the
][ down for the many people who were willing to do that. But
designing an RF modulator in meant more work, time, money (and hence a
later, more expensive product) to get the sort of FCC certification
required for devices that are expected to produce RF.
Read what Kip wrote again:

What Apple did was to get someone else to make and sell the RF
modulator. They didn't make it, they didn't sell it, and the ][
worked fine without it (using a monitor with composite video input) so
when they went for FCC type acceptance they didn't have to include it.
Of course, something needed to happen to make sure that all those
prospective ][ buyers knew what they needed to get to hook the ][ up
to the TV, and that it was readily available to them. Kip? Care to
shed any light on how this was accomplished?
Anyway, I installed a brand-new Sup'R'Mod in my then brand-new ][+
before I turned it on for the first time, and I expect I wasn't the
only one who did, so you can't take the presence of a Sup'R'Mod as an
indication that what's in front of you is a ][ as opposed to a ][+.

I am in search of BYTE Magazine from Issue #1 until December 1977.
Does anyone know where I might find these for sale and what a
reasonable price would be to pay?

No, it's not necessarily a legit copy. Autodesk sold one license
of the software, not one for each upgrade. You can't give away your
old disks if you upgrade. Licenses do not multiply when you upgrade.

Leaving aside your quick dismissal of swaths of software precedent,
how exactly do you define "separate, licensed copies of software"?
Your "disk equals license" rule seems far too wishy-washy to me.
What's special about a disk? Are you saying that every copy a
company sends you is a separate "copy" that can be given away?

A few years ago someone wrote a letter to the editor of Scientific
American about this moth. The letter quoted a letter from Thomas Edison
which uses "bug" in this way and explains the term.
The moth can at most claim to be the first time a bug was caused by a
_real_ bug.

I added another 50+ volumes to the Vintage Computer Library today. A very
ecclectic bunch of books, manuals, leaflets (no I didn't count the
leaflets). I love collecting the books because in the dry times where I
don't find much hardware they still can give that "what a find!" thrill,
especially when you find a book from the 60's (or sometimes even the
50's!) on data processing or computer science with lots of nice pictures
of old data processing gear.
However, today's quick trip to the thrift store produced a very cool piece
of hardware. I found a California Access "Bodega Bay". It's an Amiga 500
expansion chassis! First of all, Bodega Bay is a cute play on words,
since that is also the name of a northern California coastal town, perhaps
where this particular piece of hardware was manufactured. I remember last
year picking up a California Access 3.5" floppy drive with a DB-25
connector, and now I know what it went to!
The chassis is a desktop PC sized case. Inside there is a passive
backplane with several slots. There are two cards occupying two of the
slots. One is a memory board and the other is a hard disk controller. The
chassis also houses an ST-225 hard drive. The 3.5" floppy was removed
>from the A500 and re-installed inside the chassis. What is very
interesting about the backplane is that it also seems to have 4 PC-style
16-bit slots. I only had an 8-bit card handy to try out but it fit
perfectly in the "8-bit" portion of the slot. I am almost sure this unit
could allow one to use IBM compatible hardware. Am I wrong about this?
The passive backplane extends into a protrusion coming out the front of
the chassis and plugs into the side expansion slot of the A500, which
connects neatly to the chassis to form one unified computer system.
Does anyone have any solid technical information on this? Unfortunately
in all the books and manuals I brought home not one was for this thing.

Hi,
I was hoping you could help me. I have an old TRS 80 model II I just
don't have room for anymore. It comes with three BIG hard drives
(physical size rather than storage capacity). Would you happen to know
anyone in the Toronto area willing to give it a home?
Thanks...Ennio
