Great work. I always wanted to see how GP worked.
Spectacular content! I believe I was aware of GEOS "back in the day," but I did not delve into its ecosystem at the time. In fact, I don't recall even hearing about geoProgrammer until this video.
GEOprogrammer would have been much more usable if it were an IDE, not many distinct programs loading slowly between each of them, having to manually assemble each file.
Cool, I'd been interested in getting GeoProgrammer (and I had a lot of that Geos stuff) though I think it would have been difficult since I didn't have a REU or a hard drive. Good to finally get a bit more insight into what the program was like.
Have always thought it was really cool (if not totally practical) that the GEOS team chose a rich text editor like GeoWrite as the text editor of choice. :')
I was not aware GEOS is this advanced. Especially for 1987 on a 8bit computer. I only had the base disks back then, so most of these applications never reached me. Thanks for these videos, really interesting stuff! 🙂 Wouldn't the C128 version of GEOS be faster though? I can imagine you can use the same peripherals there. Also it can use the higher resolution of VDC for output which would elevate the GeoWrite experience a lot. I wonder if you can write C64 compatible GEOS apps on the C128 version of GEOS, probably yes.
Wow, that is so early Mac System Software v1.0 -like (from what I remember anyway).
Wouldn't GEOS 128 with its 80col display also be a hardware recommendation in the beginning :)?
That could theoretically create games for running directly in BASIC. It would be a buster to get back into GEOS after running. VLIR was an interesting experiment in achieving virtual memory on a 6510.
Thank you for making this, and for making it look fun! I've always wondered about geoProgrammer, but was never familiar enough with GEOS to know if it'd be worth the time to learn it. Your worked examples of using these various programming tools are useful, well organized, and entertaining. ty!
The architects of this GEOS were truly working beyond the platform.
