Yes, the fonts. It was not real Hebrew in the way Unicode allows for, but it looked like it.

There was also at least one (maybe only one?) DOS program that allowed for use of varied international fonts, called Multi-Lingual Scholar. It was expensive, and required a dongle. But it was also reasonably flexible for linguistic work, allowing right to left input in dead languages like Syriac as well as in left to right polyphonic Greek and so on. I don't know much more than that about it, although I used it a little back somewhere between 1986-87 in a University setting (Edinburgh -- we didn't have Macs).
