    Default MITS Altair Timesharing BASIC 1.0

    Hi Folks!

    Does anybody happen to have an image / copy of Altair Timesharing BASIC on paper tape?
    I'm restoring a couple of model 33 Teletypes and thought it might be a nice project to build up a multi-user system with an Altair

    Cheers,
    Dave

    I know of BASIC on papertape here (and other places)

    but time-sharing BASIC is only available on disk images, as far as I know. If you're just running an Altair and a single teletype you don't need timesharing anyway.

    Hi Bill,

    Yes, I've had the standard versions of BASIC running but the manual for Timersharing BASIC contains instructions for loading it from paper tape so I assume it was an option early on. I've gotten one Teletype running but I'm working on another 2 units. I just think 3 users on Teletypes connected to an Altair would be pretty cool......and noisy

    Cheers,
    Dave

    I have the disk based version (Ver 1.1 and Ver 2.0) archived on my website (http://deramp.com/downloads/altair/s...aring%20BASIC/), but I have never found the paper tape/cassette version. This version did exist - see the write up in this issue of Computer Notes: http://altairclone.com/downloads/com...1977_03_01.pdf.


    If you ever find, please let me know!

    If you can dig that up I would make an Altair clone just to demo it!

    Note that you can use paper tape to boot the disk version of Timesharing BASIC. This was a standard procedure for those who did not have the disk boot loader PROM (DBL). The instructions are in the Timesharing BASIC 1.1 manual. Also, see a demo at https://www.youtube.com/watch?v=FKNa...ature=youtu.be

    Using a Teletype and paper tape on a machine with disk drives just seems wrong

    I must admit, I've not looked into what is needed to run the disk version. I'm assuming it requires MITS disk drives & controllers?

    Mike, thanks for the link. I love reading through these period articles and learning about how this kit was actually used back in the day.

    Will let you know if I ever come across a paper tape version.

    Cheers,
    Dave
