For anyone interested, there is the MicroSolutions BACKPACK tape drive for
about $420 mail order.  It connects via the parallel port and is QIC-80
standard using 2120 tapes for 120MB to 250MB compressed.  It was reviewed
favorably in PC MAG April 14, 92.  There are BACKPACK diskette drives, too.
Transfer rate depends upon the speed of your PC.  I found no difference
between a 386 20MHz and 386 33Mhz backing up.  But using a Toshiba T1000
8088 4.77 MHz slowed things down drastically (used DOS 3.2).

I am reducing the price from $725 to $650 for a quick sale.

Bondwell B310:

  80C286, 12MHz (zero wait state) CPU
  2 Meg. RAM
  1 1.44 Floppy Drive
  40 M Conner Hard Disk Drive
  2 RS232 serial, 1 parallel, 1 CGA port.
  3 rechargeable batteries.
  Adaptor/charger
  Size: 13x12.2x2.2 inch.
  Weight: 8.5lb (w/battery pack)
  10.5" supertwist, nonglare, high contrast LCD display
  Real-time calendar/clock (battery backup)

Prefer to sell it as listed above. For 2MB memory, about 1.4MB of it is 
configured as a RAM drive and is very nice in running programs including
WordPerfect. The hard disk can be turned off and therefore no noise except
your typing keystrokes can be heard.

I include 3 rechargeable batteries. For new batteries, each would cost more than$50. 

The 2MB memory is very useful. If you have not used a RAM drive, you deserve a
try. The memory upgrade costed me $125. It may still cost $115 today. Think of
the price of memory upgrade and two rechargeable batteries (around $200), it's
like you get a 286 laptop with 1M RAM and 40 M HD for $450, isn't it?

I have read lots of theoretical stuff on this chip, about how it is and isn't 
a 486.   I have some documents from which indicate:

	- Intel 486sx/25 does 83.61 Landmark benchmark

	- Cyrix 486slc/25 does 78.40 Landmark benchmark

	- Intel 386sl/25 does 32.54 Landmark benchmark

Ergo, I figger performance is equivalent. 

The 486slc is a 16 bit chip, which means fewer pins.   Ergo .8 sq inches
instead of 2.25 sq in. 

The power figures on the chips are:
				Active		Suspend
				-------		-------
	Intel 486sx lp 		2.5watt		500mwatts
	Cyrix 486slc		2.0watt		.5mwatt
	

I presently have an Tandon NB 486slc here.  The only "benchmark" I have run
is running Xenix and Wordperfect and rebuilding the index on a large training
manual.   In that test it seemed about 25% faster than a AT&T6386e (20mhz
386DX with big ESDI disks).  That is a lousy benchmark for the rest of you, 
but I will run anything (within reason) anyone wants to send me.

Hi to all.  Here's the system forsale:

Toshiba 1000SE Laptop

80C86 CPU
1 Meg RAM
1.44 Meg 3.5" diskdrive
8" x 5" backlit LCD display, 80 x 25 characters, CGA
MS-DOS 3.30 on ROM and disk
Under six pounds
10" x 12" x 1.75"
--> Brand new battery (just purchased yesterday)
Ports:  Expansion, Comms, Printer/External diskdrive
Compartments for expanded memory and an internal modem

This system is *ideal* for taking notes.  It comes with Volkswriter III and
the manual.  Volkswriter III has a 170,000 word spell checker, and math
capabilities.  Plus, the whole thing fits on one 1.44 Meg disk, with over
300K room left for writing files.  That way, you won't have to deal with
carrying a lot of disks around.  Includes diagnostics and supplemental disk,
the system disk, and the power adapter.

First person to offer $350 gets it.  Also, if you have a 9600 external modem
that's Hayes compatable, I would happily work that into a trade.

P.S.  Sorry about the mistakes on the first posting.  I thought it only had
640K RAM.  Actually, it does have 1 Meg RAM.  Darn.  :)

P.P.S  People have been asking if the T1000SE can hold a harddrive.  Does
anybody out there have one with a harddrive in it?  Please let me know.
Otherwise, I'll just call Toshiba.

Thanks

The T1000SE can't hold an internal hard drive, but the T1000LE is the
exact same machine that includes an internal hard drive...the T1000XE is
also identical except that it has no floppy drive, only an internal 20m 
drive.

Why the sarcasm?  I could respond in kind, but i'll bite my fingers

I don't put the keyboard to a desktop unit on my lap, and I sure as
hell won't put an entire "laptop" machine on my lap, so who cares if
the keyboard is wider than my lap.  I don't, and frankly that's all
that matters!
 
You can call it a tomato for all I care, I just want a machine that

Has anyone heard of Uniron/Unitron U3000 laptops?  Fry's (a local
Bay-area chain) is selling these laptops (4Mb RAM 80Mb disk 25MHz 386SX)
for $1549, which seems to be a pretty good deal.  I was curious who
makes these, if they're reliable, where to get builtin modems, RAM, etc.
It has a fairly nice keyboard, and runs both Linux and 386BSD from
floppies without problems.  Thanks in advance for any info!

(There's nothing about these in the PC Magazine review of laptops, nor
is there anyone selling them in Microtimes, as far as I can tell.
Tope-a-lap hasn't heard of this brand either.)

I have the 4641, which is basically the same thing with a hard disk.
The display is actually double-CGA (AT&T/Olivetti 6300) 640x400.
Most software is available on 3.5" 720K diskettes.

The main problem with selling it is that it's a 12 pound laptop in a
world full of notebooks.  It's probably worth a few hundred dollars.

Do you mean full size keys, or dimensions of the entire keyboard are the
same as a desktop?  I have a Micronics laptop that uses full size keys,
but it is only 14" wide; the numeric keypad is "embedded".

  Amstrad used to make a HUGE luggable system, 8086 based, which had a full sized 
keyboard. I never typed on one, so can't give you any description of the feel, 
but it definately had the size you are looking for. Just don't plan on using it 
on an airplane tray, plan on checking it like a suitcase.
  You'd have trouble finding one of the beasties, though. I remember seeing close out 
sales several years ago, so you'd have to do some searching in the classifieds to find
one.

I'm currently using the Backpack Tape Drive from MicroSolutions. It is
a "250 MB" version [ (DC2120 tape) ""=compressed option ]. It connects
directly to the parallel port with no added hardware, so is ideal for
laptops. The street price of the unit is about $400-450, so while not
as cheap as the stacker mentioned above, is definitly less than
1000+. I haven't used other tape units, so I can't compare transfer
rates, but the longest part of using it was the initial formatting of
the tape (about 1.5-2 HRS!). A full backup of about 80 Meg took about
an hour, I think, which was done with compression and verification. A
changed file backup afterwords, done without compression and backing up
about 5 Meg took 15 min or less.

They advertise that support for MS LANmanager, Banyan Vines and Novell 
Netware is included. Does anyone know how. Do they have ODI driver and
use ODIPKT? Or NDIS driver and NDISIPX (would help LANmanager and Vines
too)? If so, ODIPKT or DIS_PKT would help a lot while waiting for the
packet driver.

They can of course have made an IPX that drives the Ethernet circuits
directly. In that case we have just to wait for the packet driver.

Now, which way is it?

Everybody's just gonna have to wait because I ordered one
the day the ad came out and I *still* haven't seen it in my
mailbox.

(I'm speaking colorfully, of course.  No one would deliver 
computer equipment, even an "inexpensive" PocketPC, to a
mailbox.  And I wouldn't let a USPO employee, no offense to
them, within 10 feet of my computer.)

When it arrives, I promise a post to the appropriate comp
groups.

I will say right now, however, that I for one am certainly
expecting it to be a "real pc," since that's what the ad
says it should be -- a handheld computer with real keyboard
keys, a half-height 80 x 25 screen, running DOS 5.0 and
Works 2.0 (still the best integrated sfwe pkg for MS DOS)
and leaving you the upper 384K of conventional RAM for
storage.

I expect to be able to type endlessly without a whole lot
of crimping, do basic text manipulation, competent terminal
emulation, and, if I decide I want to use it, electronic
personal management a la Sidekick.

We'll see what Zeos delivers!
