Exporting LisaWrite and other files to a modern Mac

(1/2) > >>

Over the last couple of years, I've picked up 5 Lisas and 8 ProFile hard drives. It's been a great learning experience, thanks to several members here and elsewhere.

One of my recent purchases is a ProFile hard drive that worked for the usual 10 minutes before its RIFA capacitor let loose the magic smoke. That was long enough to verify the drive's functionality, confirm that it was already in the LOS 3.1 format, and see that it contains dozens of documents from the late 1980s. Most from LisaWrite, but others as well.

Interestingly, the documents were created by a college professor in Virginia. He was teaching courses about Artificial Intelligence and Machine Learning, as well as math. His course outlines are all on this particular ProFile drive - along with lots of significant personal and family-related documents. Truly amazing that this gentleman was teaching classes about AI and ML in the 1980s. It's a treasure trove of information.

Google searches lead me to believe that he's still alive and kicking at 79 years young. I plan to reach out and offer to send him these documents, but I would like to retrieve and translate them into modern file formats so they are accessible to him.

Questions:

* What is the easiest way to convert files from LisaWrite to file formats that a modern computer can use?
* How should I move files from the LOS 3.1 environment to a modern Macintosh? I can use a 400K floppy disk, but they'll be in the LOS format and Mac OS 9 cannot read them.
Advice would be greatly appreciated.

The Lisa-to-Macintosh Migration kit was an Apple product that ran on LOS and would convert many 7/7 documents to Macintosh documents (on a Mac disk).

LisaWrite files are converted to (an early version of) MacWrite files, which still might take some fiddling to convert to something current.
LisaDraw files are converted to MacDraw (predecessor to MacDraw II and MacDraw Pro).

IIRC, the files that have no contemporary Mac equivalent are converted to text.

The conversion isn't perfect (particularly in the case of the Lisa's equivalent of OLE which allowed embedding documents from multiple 7/7 tools in one document) but useful and probably worth a try in this case.

Since the ProFile with the original documents may not have much lifetime left, I suggest the first priority is making a backup.

HTH & good luck!

This is especially interesting to me as I've worked in artificial intelligence professionally for many years.

The early-mid '80s were an interesting time in AI, as some of the techniques which have powered today's AI boom were introduced to the field back then. The computers and data that could realise their full potential were decades away, however, and so for a time in the '90s and early '00s it was assumed that those methods were a dead end.

Of course the '80s also featured AI technologies that --- well, let's say that they have yet to enjoy a similar renaissance!

All that makes this ProFile an interesting time capsule indeed. It would be interesting to see where this professor worked in the AI field of their time, and what their outlook on the future of AI may have been. It would also be interesting to see whether the Workshop is installed on the computer, and whether there are any programs that the professor or an associate has written.

I echo sigma7 in saying that it's essential to get a block-level backup of the drive (e.g. with Blu) as soon as possible. Note that as the Office System apps don't really have a way of closing documents without saving them, I'd refrain from even opening more documents until you have a drive backup saved in a secure place. The ones you have opened already have probably already lost their original save dates+times, even if the file contents have not changed.

Thanks for sharing this with us!

Very interesting!

Yes, getting a BLU backup is priority #1. Once you have a backup, you can use LisaEm to pick through the contents without modifying the originals.

I know Ray’s lisafshtool has a utility for extracting files from the disk, but (1) I don’t know if it works on ProFile images, and (2) you’d lose all formatting, which would be nice to save somehow if possible.
