Some ideas come from MAME emulator's GRiD implementation by usernameak.

And big thanks to usernameak personally for his research and consulting

• This is early stage. Lot of things not working.
• So far I am working only on 1101 emulator because need to finish peripheral hardware emulation.
• For now ROM is running up to stage where it tries to boot from GPIB or bubble memory. This is normal in current stage.
• Lot of work to do.
• Don't complain about functionality in this early stage.
• Bubble booting sometimes working

Sorry, Windows support and PC XT hardware removed from original code.
