Hi Guys,
I've just posted another update to my ImageDisk program to my site.
The main improvement is that I have added a new program called BIN2IMD which
allows you to create .IMD images from raw binary sector dumps (such as you
can get from many other formats, emulators or just by "taking apart" another format
image). It's pretty flexible, and can make mixed format disks etc. ussing sets of
rules you give it telling which sectors from the binary file go to what tracks/sectors
on the disk. This is essentially the opposite function to the /B option I added to
IMDU in the last release. I have used it to make physical disks from binary images
sources which were not previously .IMD format, and it has proven very useful.
Also, since ImageDisk is getting quite mature, I have added a manual, separate
>from the help files. Feedback appreciated.
I have also made some minor cosmetic fixes, spelling corrections, and improved
the file selection manual entry mode in ImageDisk so that you can directly access
files from other paths.
For anyone who doesn't already know: ImageDisk is a program for archiving and
restoring soft-sector floppy disks to image files using the PC floppy controller
hardware. It is compatible with any format which can be read/written by the PC
hardware (including mixed mode/density formats). The image file format is
fully documented, allowing you to access the data from the diskette by other
means if you need to.
Regards,
Dave

Subject: OFFER_ Sun Sparc Station 5 Total 6 gb-New Windsor Area
My son has moved and could not take this computer with him. It is not
a typical computer rather a UNIX. It is made by Sun and all pieces
are from Sun. Features included:
Sun Monitor
40 mb Ram
Solaris 2.51
CDE 1.1/WABI2.2
External CDRom
External Hard drive
2 Internal Hard Drives
24 Bit Graphics Card
External Sound Speaker.
He is asking $125.00. Pictures available upon request.
New Windsor, NY is in Orange County, NY, USA. Anyone nearby
interested? I'm not big into the sun stuff or i would have jumped at
it and no, I know nothing of the poster/owner.

It would be wise and even a good idea to see whats inside and what model
as if you don't know we can't even guess.

Lacking further infomation it's really hard to guess from here.

Yes, but there's a limit on the size of a single drive in ADFS.

I have an ADFS E copy of the contents which I could zip/tar if that's
any help. Or if you have a spare DD 3.5" disk I can make a copy (I
have some software to do that much). I think what you're really
looking for is the NetMgr program.

I use Firefox exclusively (took IE off the system completely even registry)
and it renders fine for me. Major nit I have is their site is slower than
sludge even on a DSL which is typical for MSbased sites.

Yes, I've run them that way -- but only under ADFS. I don't know what
the Level 3 Fileserver would make of that. It can't hurt to try.

Ah, another reason you probably ought to pay another visit here
sometime!

Not terribly, but enough to know that VG Anylan carries Ethernet
packets; it's only the physical layer that differs. No carrier
sense/collision detect but instead it uses access rules called Demand
Priority to ensure there will never be a collision. That,
incidentally, is why the switches are smart and not like ordinary
Ethernet switches. Also VG Anylan uses all four pairs in the cable;
10baseT and 100baseTX only use two pairs (100baseT4 uses all four
though, and for the same reason that VG Anylan does -- more bandwidth
on inferior cable. VG stands for "voice grade", ie Cat 3 or similar).
Anyway, Ethernet packets are one reason a card can be both Ethernet
and VG Anylan.
Also most HP cards were made dual-standard -- one physical 10baseT
interface and one physical VG Anylan interface -- as a transition
mechanism. Often they had two connectors , but sometimes just one that
can be configured or autoconfigures. HP's website lists these as
dual-standard, probably by detecting signals on the second and third
pairs.

Well, that's fine for a Filestore. I'm not sure it'll work for a Level
3 Fileserver, because that expects to just use a winchester. I'm
willing to be proven wrong, however.

That won't work. Those disks are 3.5" disks for a Filestore, in
Filestore format. How are you going to write Filestore format from a
zip archive?

They are Vero cases. Not particularly cheap. No, the software
protocol didn't change. Anyway, that wouldn't affect the test
circuits.

The 100VG Ethernet cards use all 4 pairs of a CAT3 cable to get 100Mbps
bandwidth. As such they are NOT compatible with Fast Ethernet switches.
However, I have a crossover cable that I have used to interconnect two
Intel 100VG cards. This is the crossover cable:
gr-w or-w
