Hi
This is why I think it is important to find ways to move
data from and to old media. This is why I've been working
on the methods for transfering data to and from the H89
hard sectored disk. I can take advantage of the higher density
storage of the newer media and still restore the software
to a media that can be used by the older machine.
It is best to save as much older media as possible but one
also needs to be realistic. A room full of tapes can easily
be put onto a single disk drive of today. First level of importance
is to save the information.

We have a couple of large format plotters in working order. One is an HP
A3 plotter the other a very large Calcomp. I thought it would be nice to
show these actually working and am searching for plot files of the
classic pictures, for example the cut-away drawing of the space shuttle.
Anyone know where such data files might be found?
Regards,

I have a couple of VT320 serial terminals available if anybody can
use 'em. Baud rates up to 19200. Suitable for logging into a Linux
box (or similar Unix box) over a serial port, or for setting up
networking gear via a serial console port, or for many other classic
computer applications.
Free to collector, North Bristol (M4/M5 junction), UK.

Hi Ed
I do have a number of the Donner resistor patches and a
few of the capacitor patches. As Doug states, the resistor/cap
patches can be made with standard dual banana plugs. The
resistors usually start at about 10K and go up to 10M.
Values of 1,2,5,10 are typical. You want these to be stackable.
The capacitors are 0.1 and 1.0 uf. You want to use caps with
low dielectric absorption and good temp stability. These
are used for integrators that can run over several seconds.
And, no, I don't want to part with my patches. Pomona
makes what you need.

Norton had a program called wipedisk, which wrote to the whole drive, and
there are some shareware programs also. However, if you use Fdisk and
remove all the partitions, and then create a single partition, then do
a format /U/V then that will pretty much clean out everything. I have
heard from some sources that nothing is ever completely gone and No Such
Agency can actually pull data off a drive that was erased and reformatted.
I have a hard time believing that one. Are you concerned about security,
or just erasing and initializing the Drive?

I just pulled a really interesting-looking expansion board from a dead
Heathkit H-89 I acquired a few months ago, and I was wondering if anyone
knew anything about it, and/or had documentation and software to support it.
And I know is what I can see; can't find anything on 'net.
It's an N.O.G.D.S. (New Orleans General Data Services) HA-89-3-B. This
thing is a whopper, the only thing it doesn't seem to have on it is another
CPU. It has:
* AY-3-8910 sound chip;
* SC-01-A voice processor chip;
* ADC0809 (there are four ports marked JOY1-4 on the board, so I'm assuming
joystick pots);
* 8253 Timer chip (some of its outputs extended to a 10-pin header);
* 8259 Programmable Interrupt Controller;
* TMS9918 video display processor and supporting RAM (there's cable running
off the board that terminates in a RCA jack), for a second video display
apparently;
* AM9511 math coprocessor;
* a couple of PALs and the usual array of buffers and decoders.
So for all things, this looks like it was meant to support some really
interesting applications on the H-89, maybe drawing/CAD, etc. (but the sound
and voice chips?). The machine it came in also had a battery-backed
real-time clock expansion board (with AA battery that leaked down onto the
flyback transformer, yuck), and a parallel port board.
I'd love to play with this thing, but I thought I'd ask before I spent
hours following traces...
--Patrick
Interesting coincidence... I was talking to someone this week who wanted
to recover some H89 discs that have the FORTH programs he wrote for using
this board.
I'll see if he still has the manuals.
I thought it was Ventura Publisher for the PC version of DRI GEM?

Worth saving, especially if in good condition. Color screen. Dual 1 Meg 8"
floppies, External HD available (I had a NEC 5 1/4" drive for one once) .
Crossover machine CPM-86 & MS-DOS, used DR's Graphic extensions (GSX?), ran AutoCAD
1.X.....
Of all the collectibles that went through my hands it is one of my favorites.
The biggest disadvantage is it is large and heavy.
