I have an unused and unregistered copy, complete, of Zenith Data
Systems/Heath Company's "Breakthrough Timeline" which appears to be
a
timeline creator/project manager. It has the original box, manuals,
key
template, registration certificate and the original 5.25" 360k
floppies
(still in the envelope). From scanning the manual it's roughly
1986/87
vintage and should run on most any machine from 8086/8088 up
through our
present array of hardware.
Really good condition visually too, might be good as part of a
collection.
Need $12 for it which includes mailing in the 48 CONUS states.
First
come, first serve. Email me direct for info.

You don't cut it you grind it! If done on a lathe you turn the rubber
part and run a high speed grinder against it. It's insures it will be
concentric and gives a smooth surface.
the alternate is to spin the tire and work against a hard surfaced
abrasive board.

disconnect the motor and power it from a supply rather than risk cooking
the drive electronics.

that is an issue too. the solution is to demount the moter and work off

Hello, all:
Another crazy project...
While working on my old-DOS decompilation project, I've found that it
would be handy to have some sort of ICE hardware/software to watch the
boot-up sequence, examine specific registers, test code fragments, etc.,
without crashing my PeeCee. I've been using Debug and testing code fragments
to watch changes in the registers.
Can anyone point me to a GNU/shareware software-based ICE program, much
like NuMega's Soft-ICE Windows, that can do this for DOS? Is it even
possible to use a software-based ICE in this instance (because it's before
DOS boots).
How about this...how about a virtual PC running under OS/2 or Windows
NT? It would have to be re-bootable (without crashing the host operating
system) and support hot-key break-to-debugger. Sort of like a cross between
the vMac Macintosh emulator and WDEB386 (the Windows Kernel debugger). It
would be odd to emulate an 8088 on a Pentium 233MMX...hmmm...sounds like a
project.
Any thoughts???

I'm not sure anything beyond ethernet would strictly be considered
'classic', but I have a set of DS5000/200s connected via FDDI.

So I've captured a few new machines - now all I have to do is figure out what to do with them.
1. Fortune 32/16 - System, seperate SCSI tape drive, no HD. No software. Help!
2. 7 (count 'em, 7) Wang systems. I'll have model numbers &such tomorrow (something along the lines
of PC-02). Only three monitors, only one keyboard. Two 5 1/4 flopies per, no software. Any help
would be a start. Most have Network cards of some kind - is this ethernet? Each has two BNC
connecters. Almost looks like a daisy-chain system of some kind.

I've seen them in computer magazines (Computer Shopper) for $15-20. You
may also be able to try a computer show.

I know I've seen these, but would anyone have some suggestions as to
how to go about building a little board to connect laptop IDE drives to
standard PC IDE interfaces? I gather it would just involve lining up the
pins, and adding in some power. I have seen them for 20$ US in stores,
but my searches as of late have uncovered nothing. anybody do this on a

One thing to check first. Has the drive roller turned to goo? the tend
to age badly and turn into a sticky mess. I have a fix however.
If that is ok with the cover off whatch the action of the led on the
controller board. If show activity all is good.
generally, if the drive roller is good you can count on the rest.
