I do now if this was ever released in the USA or not. This was another memory snapshot cartridge.
Freezes – Freezes and saves programs to disk
One File – Programs are saved in one file
Compacts – Programs are compacted to reduce disk space used
Saves More – You can save 3 or more programs per disk
Not Needed – The cartridge is not needed for loading saves
Upgradable – The cartridge used RAM and disk based software for instant low cost upgrading
Monitor – Use the machine code monitor to cheat, gain extra lives, etc
Also for Tape to Disk backups
The cartridge was also reversed engineered and a reproduction was sold on Ebay.
Claims: The worlds fastest copier! It takes only 21 seconds to duplicate an original diskette, one keystroke provides the user with a complete backup. It works every time!
Also 21 Second backup will not work with the Burst Nibbler Cable. The program looks for this cable and will not work if the Burst Nibbler cable is found. This is because the cables are different.
This disk is VERY RARE and sells for over $100 when it pops up on Ebay.
The ECHO was developed by Jim Drew.
The Echo and it’s software was released before the Shadow (Megasoft)
The Echo software also because the Supercard version
From Jim Drew, “ECHO was sold for about 6 months or so (through my company called “UnderWare”) before it was renamed as Supercard and sold through Utilities Unlimited, a spin-off company that Reggie created due to the Shadow disaster which destroyed Megasoft. UnderWare had ads in Compute!, RUN, and several other magazines. I sold ECHO, X-RAY (a density display), and a few other products. ”
