I have uploaded them to the download section of the site (see the link to the page on the left). These emulators are:

• my EACA/Videogenie/System-80/TRS-80 emulator is now at version 1.6.1
• my Commodore 264 family emulator Yape is at version 0.83
• my HomeLab/Aircomp emulator has a bug fix release 2.2b (potential crash under Vista and staying in memory after quitting issues fixed)
