Application for Equation Editing (?)

Post by saba »

Hello!

I have recently set up Basilisk II, and have managed to transfer a bunch of files off some old Mac diskettes that I have had lying around forever. I also managed to identify and install a majority of the applications I used once upon a time to create these files. But there is one application I can't find. The file type is EFIL, the creator code is EQED. I have borrowed a real Mac (to support transferring data off the disks), and when displayed on the Mac screen the icons look like in the attached picture. Appparently some kind of equation edotor. I have tried Equation Editor 1.0B, as well as Expressionist 3.14, no success.

Does anybody here recognize the file/creator codes and/or the icons? It would be nice being able to fire all the old stuff back up again.

Nothing comes to my mind, but I will mention that it is worth checking (and requesting) at Macintosh Garden if you don't get an answer here.

They have a forum: https://macintoshgarden.org/forum

Thank you for the Macintosh Garden forum hint, I'll give that a try too.

I think the Application is called MathWriter.

Yes, that is definitely the one! thank you so much. Perfect match on icons. Now comes the challenge of finding the actual SW, but it's MUCH easier when you know what to searh and ask for.

On this subject, maybe Tyler can help. I found this database of creator codes and file types:

https://www.macintoshrepository.org/104 ... -database-

It opens in Panorama, and I was able to open it in Panorama 6 running in a High Sierra VM (where I found that it listed MathWriter as the probable creator of the file the OP asked about), but when I tried to use the Text Export wizard to export the text, I got an error. Is anyone able to open this database and export it to a modern format?

EDIT: Tyler tells me that the database is downloadable in Excel format here:

Next time, I'll know to ask Tyler before spending time on these problems!

Edward,

You can get a final excel file of the database here:
http://www.lacikam.co.il/tcdb/

It seems MathWriter isn’t on any of the Macintosh repositories. It’s for sale on Amazon, but I’m sure someone may have a copy here.

Thank you so much for valuable information. For sure it must have been MathWriter I was using back in the days at university, both creator code in TCDB and icon as shown in the .pdf scan of the manual comfirms this.

There seems also to be at least a couple of copies residing in different locations in the US:

The second of those links is to a book. The first is a catalogue record but not a link to the software. The app doesn't seem to be accessible anywhere...

Yes, of course I am aware those are just records, not the actual SW. But the Princeton record states

"Description
Computer program.
1 computer disk ; 3 1/2 in. + guide (vii, 106 p. : ill. ; 23 cm.)
"

So it seems they own not only the book but also the SW. If this record is reflecting current status, one could in theory borrow the item from Princeton, including a 3 1/2" disk. Though only possible for students, it seems.

So yes, they are both catalog records, but still some kind of evidence that the software still exists somewhere in the world. That was all I tried to show in my post.

You are absolutely right. The book did seem to come with a disk.
