The files in this directory are from the archives of Issue, the organization I founded in 1986 and ran until about 1994. Winding up Issue was much regretted, because among Sirius users a sense of comradeship existed unlike that for any other micro.

Yours still Siriusly,

Notes

If you have a Sirius with no operating system (boot) disc, by far the easiest way to go will be to find someone with a working Sirius and have him make you a copy. At present I have an archive disc but no means of making a copy, and the disc format is non-standard. However, be assured that there are still working machines owned by Sirius enthusiasts out there!

Enough information is here to boot a Sirius from nothing but it would not be a trivial task. On each boot disc MSDOS.SYS has been archived by PKZIP (on the Sirius the Bios and DOS are combined in MSDOS.SYS, which is normally a hidden system file). However what has not been saved is the (disc) bootstrap to MSDOS.SYS - you would need to run SYS, FORMAT, SYSELECT or SYSGEN to create a bootable disc. Of course you need a booted Sirius to do this! IDRIVER is a device driver for an expansion board we produced which interfaces an external MFM (720K) drive, but we never got round to writing the code to boot off the external drive. It is also possible to boot from the serial port.

An interesting project would be to write a PC program which booted a Sirius via its serial port. Then you could restore the OS, download the rest of the stuff here and Lo! a working Sirius, started from nothing.
