Sure! I wrote a small "parser" that generated the font. I'll clean it up and send it to you so you can use it if you want.
It requires some special handling of the punctuation ( . , : ), it works ok for me, but not the"flying goose" yet, need another flag for that ...

And as Meindert also mentioned, I probably also need to add a driver (like 245) to get ISA driver to work. But I still have some gpios free on the Tiny for that!

Thanks.

Feel free to use my code. That uses a 74LVC245 as a level shifter and also has the ISA drive to emulate a ROM. It's all pretty simple really.
