custom made for using the Thesaurus Linguae Graecae Data. When the
Packard institute first produced this data with a huge donation from
Packard himself to pay for all the man-hours, they
found there was no hardware that could easily edit the stuff
electronically. So they made it.
Ibycus was revolutionary in that you could type English then press a
button and type Hebrew from Right to Left. It took IBM PC about a decade
to catch up with this. ( Actually, mixed Left-to-Right
English and Right-to-Left Hebrew was first available on the Amstrad CPC
computer, using software made by me. I needed it for writing my thesis,
and I sold it to most of the synagogue newspapers in the UK, who all
bought Amstrads because PCs weren't capable
of doing this.)
Very few Ibycus computers were ever made. I think there were only a handful in the UK.
