".. The Calc/Word-Result dongle is made of leftover "Bridge64" for Vic64, they just cut one wire on the contact.
I used to work at Handic Software ...
While looking around more on the net I saw that they said that they have found out handic software dongles containing character rom chips ... So what I wrote is not correct for all software from Handic Software with dongles. And yes, they was only used as dongles. Some vic64 games there where the game in the cartridge.
I remember that bridge64-roms were used as a dongle for another program from same company. .."
