Altair 8800 Clone Firmware Version 1.81

[AltairClone]

A minor version update to 1.81 has been posted on the support page:

When the Turnkey module is enabled, force the entire 1K address space of the Turnkey module to be ROM even if less than 1K of ROMs are enabled in the Configuration Monitor. This more accurately reflects the real Turnkey module and ensures that ROMs that search for the top of RAM see no RAM past FC00.
