CompuAdd 810 Utilities Disk

[jmetal88]

So, I don't know if anyone in particular (besides a couple of people I've already privately messaged) might be looking for this stuff, but I found two copies of the CompuAdd 810 System Utilities Disk at my parents' house this weekend. Unfortunately, the 720k copy was completely unreadable and the 360k copy was severely damaged, but I was able to recover a number of files, some of which are useful additions to the system.

Here is the archive:

Note that the CLOCK.SYS driver was acquired separately, and didn't appear to be on the disk I was trying to copy, but all of the rest of the files are straight off the 360k Utilities disk. Of particular interest, the SW and DIAGMENU utilities that are mentioned in the 810's manual are on the disk, and appear to be functional (although I did not get far in DIAGMENU because it seemed to want to set up the hard disk, a process I didn't want to go through because I am now using an XT-IDE in the machine).

UPDATE: DIAGMENU will not actually run the diagnostics, even though it lets you set them up, because it is missing several support files. Oh, well. At least SW is present and working, the chief upshot of which is that you can use it to set your system speed in your AUTOEXEC instead of having to remember to press the keyboard shortcut after you boot.

UPDATE 2: I manage to extract the CLOCK.SYS driver off the disk image I made of this using a hex editor. Its directory entry was damaged, but the file itself was intact. I have tested it out and it runs, and shows an updated version 1.1, as opposed to the 1.0 version shown by the driver I previously was using.

Here is a direct link: http://mkgraham.dx.am/CLOCK.SYS

I have also added it to the archive in place of the other CLOCK driver.

I decided to upload the best image I was able to make of the disk as well. The directory entry is damaged so unfortunately it is not usable as a 'restore to floppy' type image (I do not know why DOS seems to be able to read a partial directory entry and yet it does not show up in the image -- maybe a Kryoflux would do a better job with the duplication but I don't have one to try), but maybe someone adventurous could try to manually extract the other files as I did with CLOCK.SYS above if they feel they have a reason to. I think I've gotten the most useful files off the disk already, though, so I'm probably not going to do much more with it.
