Xerox Alto - Salto Simulator

Post by geophoto3 »

This may be old news - but just in case anyone is interested - the "Salto" emulator can boot and run a number of disk images from the original Xerox Alto. The code is available on bitsavers. The software must be compiled - I've done so with Ubuntu 10.10. The source code is here:
http://www.bitsavers.org/bits/Xerox/Alt ... lto-0.4.2/:
There are a number of disk images here:
http://www.bitsavers.org/bits/Xerox/Alt ... lto/disks/

I've been able to play a few games and mess around with Bravo. My real interest is in Smalltalk 76. The disk image is there, but it either does not work or I don't know how to start it. Any hints?

If the image hasn't been corrupted, you use the 'bootfrom' command

bootfrom xmsmallboot.image

I don't recall it working correctly, though.
The Computer History Museum is waiting for a signature on a release of the Alto
software for non-commercial use. When that happens, I'll put up some other images
that I've been holding on to.

yksoft - thanks for the windows build! Nice!
Al - thanks for the tip - I'll give it a try. I really hope you get the permission you need. I'd love to see more of this important historical stuff available.

Awesome work on the emulator.
And thanks to yksoft1 for the Windows version. I am very keen to try it out, but the Mediafire download link does not work (file not available). Can someone please re-upload ? TIA. :)

Edit: Before anyone says "Google is your friend", I searched on Salto +Windows +MinGW and similar searches in Google and got no results that provided a working download.

Actually they did release a bunch of Alto files: http://xeroxalto.computerhistory.org/

But these aren't in disk image format, and I'm not sure if anyone has gotten any of that going under SALTO.

I tried out the Salto simulator at https://github.com/brainsqueezer/salto_simulator and it's very cool. Is that the latest version? Are there more disk images available? Is anyone currently doing development on it? I'm working on restoring an Alto, so I want to learn more about how the software works

In order to get Smalltalk 76 working you'll need another Xerox Alto emulator called ContrAlto: http://www.livingcomputers.org/News/Ann ... lator.aspx. It is very slow so you must be patient. Loading Smalltalk can take up to 20 minutes.

With some luck you can get image editor working ;).
