Doing file(1) on it, I get...

$ file zap
zap: mc68k COFF object not stripped (demand paged)

 I also happen to have another version (not from github)

$ file sun/zap
mc68020 demand paged dynamically linked executable not stripped

_That_ one is a Sun3 binary.

Maybe install Oracle VM VirtualBox (freely available as Open Source
Software) on your 64-bit Windows system and run a 16-bit or 32-bit
environment inside of that which can run PUTR. (Or install some other
VM software of your choice).

I run Windows 2000 inside of VirtualBox occasionally when I need to
run some old 16-bit code that won't run in a 64-bit environment. Files
can easily be moved between the VM and the host system.

I used PUTR in the past when I wanted to assemble some code with the
RT-11 assembler but wanted to edit the source code elsewhere and then
transfer the code into a SIMH disk image.

I've found the most convenient way to do this, for a file or two at a

Two more options.

Get PUTR from dbit.com and use it to move the files onto an image

I have an 801, 802, 803, 816, and TPC-I. I think I still need to image the
ROM from the TPC and 802.

One thing I noticed is that the 803 ROM isn't the same as the later ROM
shipped with the 803H. The earlier rom tried to talk to a hard disk using
the code from the 802, at the wrong IO port. I ended up burning a copy of
the 803H ROM from Bitsavers, and then was able to get it working with a
hard disk interface.

It'd be nice to have a copy of the disk and ROM for reference. It seems
like the disks that TeleVideo used failed early and often, so it's probably
best to image that sooner rather than later, and hope that it still works.

An image from an 816 disk would be more useful, though, since I have the
rest of the 816.

SIMH question

[Charles via cctalk]

This may be a silly question... but how can I transfer a text file from my 
PC into SIMH for PDP-11?
Is it even possible to create a disk or tape image from source code? 
Attaching files requires them to be images...


I have significant changes to make to TSGEN.MAC (TSX-Plus definitions file) 
and it will be MUCH easier to edit it on my laptop with a screen editor, 
than in SIMH (or on the real hardware) using the line editors!


The only method that comes to mind is to start the actual 11/23+, open the 
text editor for input, then use a terminal program like Teraterm to "play" 
the file as though I were typing it in.
But I don't have the rest of the TSX-Plus source files, linker, etc. so I 
would have to transfer them using VTserver anyway...

thoughts?

thanks

RE: Telex 20 Meg 10 platter very heavy monster drive needed drop line off list..r

[Tom Gardner via cctalk]

ISS was an independent company in the era (late 60s) of the 714 (IBM 2314 
compatible).  It was later acquired by Itel (a leasing company) and then by 
Univac and sort of disappeared in the 80s.

Depending upon your application almost any plug compatible 2314 might work or 
could be made to work.  The interfaces were very much 2314 like except the PCMs 
and OEMs didn't use IBMs +/- 1.5v signaling levels on the interface but instead 
used DTL driver/receiver signaling.  There was also some weirdness in the power 
sequencing all of which can be worked around if u are up to it.

The thought had crossed my mind, but only as a last resort.  I'm not
entirely sure what the internal fault is, but the end result is two rows of
every character have all bits stuck "on."  I've verified that the ROM
addressing is correct and that there's nothing on the output side causing

The desktop models (-60 and -95) have a large integrated main boards with 
plug-ins for comms options.
I have one of each, I have them pulled apart right now to take pictures.

Some decent pics of the -60R are here:

Could you take some pictures and image the 5" floppies?
Is this one of the big floor standing units  (1174-10C) ?
Did you get any docs with it?

I was wondering what TS-8xx systems you have that supported RS-422,
and if you've dumped the firmware from them.

I can request the TS-806/20 in the collection and dump the firmware
and disk if that would be of help

Considering that 925s are really common, and a replacement EPROM should be
easy to source and program, this sounds like an overly difficult approach
that will yield something different than what he wants.

Is the ROM totally bad, or just losing a few bits here and 
there? If the latter, you could probably read it out, figure 
out how the rows, columns and characters are mapped, and fix it.

I should be able to do that for you if you don't find someone else with a
dumped room sooner.

Ultrix 3.0 VAX

[Dennis Grevenstein via cctalk]

Hi,

I am looking for images of Ultrix 3.0 installation tapes for VAX.
I know that there are some on bitsavers:
http://bitsavers.informatik.uni-stuttgart.de/bits/DEC/vax/ultrix/3.0/

However, I cannot boot them in simh. There are also 4.0 images
that boot fine. I then installed 4.0 and looked at the 3.0 tape
images. I could extract the base 3.0 filesets, but the standalone
parts that allow booting a system appear to be missing. Thus,
I could not even setup a remote installation environment.
Can anybody help me out with bootable Ultrix 3 tape images?

thanks,
Dennis

Do you mean DIGITAL/Compaq FORTRAN for Windows? Or something older such as VAX 
Fortran which had many extensions.

Televideo 925 character rom dump

[Josh Dersch via cctalk]

Hi all --

I'm working on a Televideo 925 terminal with a few problems, one of which
is a bad character generator ROM, (a MOS 2332).  Does anyone have a dump of
this already, or have a working 925 they'd be able to dump the ROM from?

Thanks in advance,
Josh
