Just as an update on the Vault OS planning stage ... now that I have the tablet PCs (which came without any bootable hard drives) up and running ... has anyone used CA-Clipper 5.3b 32 bit protected mode for DOS?
It's apparently got a graphic GUI, multitasking multiuser environment, an IDE for 4GL style design (similar to VBDOS) and a full scale SQL database with server and LAN support built in right out of the box. The database supports streaming of binary data like BLOBs for images and sounds.
All I know about it is from talking to a guy ten years ago who swore it was the greatest thing he'd ever seen running in the DOS environment.
After researching it a bit on the internet, I discovered it has some support for real-time and embedded style control in addition to a report designer, menuing ... the works. There's also an open source version called CLIP but I need to learn more about that as well.
This might be better than Damn Small Linux, smaller run-time, there is even a documented watchdog function to reboot the system if it falls over ... !! This might present the best possible environment to run the Vault OS on if you are staying in the DOS x86 system.
After running Damn Small Linux for a while I noticed it has to access the flash a lot. It's very quick but there have to be fifty megabytes of files there to support the base functionality of DSL for most stuff. That seems like it might be overcomplicating the system when my original goal with VBDOS was to keep it idiot simple and all running in one big integrated foolproof system.
Any feedback appreciated.
