Morning all.

Way back in the olden days before Windows in the era of DOS 3.2. long before PowerPoint was a dream, there was Harvard Graphics. A real POS program but it would let you build a presentation like Power Point does today. Some of our customers would print it out on their crazy expensive inkjet printers and bring it to us to make copy slides so they could present it with a slide projector.

We had a film recorder that would take the digital file directly to photographic film at 4096x2732 resolution. It used a language called SCODL that as I remember stood for Scan Conversion Object Display Language. Anyway, it was real picky about how it worked. We had a electronic box with lots of lights on it that could convert the file, but it took 30 minutes per slide. This was in the days of a IBM PC AT running at 6 Mhz, with 2 MB of RAM and a 32 MB hard drive. I figured out how to get the computer to send the file directly to the film recorder in "only" 8 minutes per slide. It required you to change some drivers in the Autoexec.bat and command.sys files. Those drivers messed up lots of other functions for regular operations. So I had to boot from a special floppy. A 5.25 inch 360K floppy. When the slides were sent, reboot and be back to normal.

Good Friday morning everyone!
