+Notes
+---
+
+The Microsoft Chart 2.02 disk is clearly not an original distribution disk.
+
+The disk image contains "SPERRY Personal Computer MS-DOS 2.11 version 1.11 Copyright 1981,82,83 Microsoft Corp."
+with a COMMAND.COM dated "3-16-87".  It boots but then crashes when COMMAND.COM attempts to display the current date.
+
+COMMAND.COM appears to be loaded too high in conventional memory, because it builds the current date string above
+segment 0xA000, so when it attempts to print that string, DOS finds only garbage (0xFF bytes, and no terminating $).
+This suggests that either there is a mismatch between the IBMBIO.COM, IBMDOS.COM and COMMAND.COM files on this disk,
+or that there is something special about the BIOS found on a SPERRY computer that is critical to booting these files.
+
+I'm sure with further debugging we could find out one way or the other, but let's leave that for another day.  It's not
+clear it's really worth the effort.  To start, the IBMBIO.COM, IBMDOS.COM and COMMAND.COM files should be placed onto
+their own MS-DOS disk image and archived appropriately.  A search for the rest of the SPERRY OEM distribution files
+should also be conducted.
+
+I would much rather post copies of original distribution disks here, but this is all we've currently got.
