I have a rev 0 machine with 48K + 16K Apple Language Card - and nothing else. No disk controller, nothing. All other slots are empty.
When I power up with the Language Card installed, I get an all-white screen in lo-res graphics mode. Pressing RESET takes me to Integer BASIC.
When I power up without the Language Card, I get the same all-white screen. Pressing RESET takes me to the monitor, and CTRL-B from there takes me to Integer BASIC.
My understanding of how the Autostart ROM on the Language Card should work is that power-up should perform an automatic RESET and take me directly to BASIC if there's no disk controller installed.
I swapped in a spare Language Card, with the same result.
Am I misunderstanding the Autostart ROM? Or could there be something wrong with my motherboard?
