I have a tape image of ALTAIR BASIC 5.0 [14JUL78] [DISK EXTENDED VERSION], I don't remember where I got it from, and it starts at 0000h. It's not a straight binary image, it needs to be loaded with a standard Altair tape boot loader, either the MBL running from a PROM, or one toggled in on the front panel. If you don't have MBL, you have to be sure to use the correct first stage loader for your tape. In either case, you have to set the sense switches correctly to tell the loader and Basic which terminal device to use. Let me know if you don't have a copy of the first stage loader and the switch settings, I can probably dig them out of my manuals.

Geoff.
