Anyone loaded 8K Basic (4.0) with an SIO-A Rev zero ?
Well, I can't.
I can load 4K Basic just fine using switch A14. I tried the
recommended A13 with 8K and no go. A14 doesn't work either. A little
had dissasembly showed it was looking for A14 A13 and A15 A14 A13
patterns, so I tried those combinations. When I had A15 A14 A13 up, I
got "MEMORY SIZE?". However, hitting any key results in that key
being echoed to the screen in an endless loop.
I tried to duplicate what I was doing on the Altair32 emulator, but it
appears to be running a 2SIO, not a SIO-A card. Er... "virtual
card". It would be really cool if there was a database of card stats,
along with a graphic of them. You could click and drag cards in & out
of your open-topped Altair graphic to easily reconfigure your system.
A toy for the hardware geeks as well as the software ones. I can see
custom made virtual S-100 cards for sale on ebay....(Rich, are you
But that's another life. In this one, I can't even get Basic running
