[Coco] Why haven't we got this?!!

Thu Jan 23 13:30:55 EST 2014

I have tested it on my Panasonic FS-A1 WSX with a 512KB memory mapper
and it runs at an impressive speed for a Z-80. But the panasonic has a
1.5x turbo mode, running at 6Mhz.

The video just shows a Multivue like screen clicking some menu choices. Yes, the menus are a little more like "Windows" but that's just a matter of where you put them and how you arrange them.

If you notice when he clicks on "drives" in the menu choices he gets file selections almost instantaniously and programs run in a blink of an eye. ummmmm Even a PC with an intel 486 wasn't that fast. That's running on modern day equipment not an 8-bit Z80. I get the same results in Nitros9 on an overclocked VCC on my AMD Quadcore machine

>> This being said, these guys have put a lot of work into this and it looks really good. The rescaleable/resizable/relocatable/overlaying windows was something the OS9 upgrade team was working on in the early 90s when Tandy and Microware pulled the plug. Just read all the notes and docs on the Brother Jeremy Upgrade disks. All this was being done. A lot of it was completed. No one knows where the sources went. I'm sure Boisy, Alan deKok and others looked pretty hard to find them but from the notes in the nitros9 repo, most of what they got, they had to disassemble from Brother Jeremy's disks and if it was written in C, then it was (for the most part) lost. Those disks only included the "finished" features and none of the planned and unfinished stuff.

>> What the Symbos developer did was take a lot of these features and integrated them into an OS9 like OS then added support and drivers for the "super" features of the FPGA emulators. Most of which will run only on the FPGA super machines with the basics being able to run on the originals.
>>
>> Again, it's pretty impressive stuff. The only reason we don't have this in Coco and OS9, is that every time someone starts a project to "expand" the capabilities of the Coco, in FPGA or RPi or any other "project" system, they get baraged with "That's NOT a Coco !" and "The Coco didn't do that !" and "I only want it if I can run my 1984 floppy drive that only runs when I clean the heads and beat on it with a hammer for 10 minutes" and then everyone else is wanting Windows 8 features and unreal additions.
