SECTION TWO - FRONT PANEL OPERATION
This screen gives internal information about the system. Lines 1 through 5 show memory
allocations to DOS, CNC overlays, and the heaps. Line 6 shows the MS-DOS version and
whether the CPU is an 80286, 80386, 80486, or 80586. Lines 11 & 12 show the compiler and
blocks pre-allocated for canned cycles, text cycles, and custom M and G codes. Line 13 is a hex
dump of the BIOS ROM area at F000:0. Line 14 is a hex dump of the Disk Emulator ROM at
CA00:0. Line 15 gives a guess at the Bios type and Disk Emulator type.

The first line gives the front panel version. The next two lines show several abbreviations and
numbers:
AK Acks received from keyboard encoder/controller
RT ReTrans received from keyboard encoder/controller
TO Timeouts on transmissions to keyboard encoder, detected by keyboard
controller
SR Slice resends - timeouts detected by CNC
SS Slice sends - standard sends to keyboard encoder
NK Nacks detected by keyboard controller
DC Spindle DAC value send to keyboard encoder
PE Parity Errors detected by keyboard controller
TL Time Limits detected by keyboard controller
CL Control pressed received by keyboard controller
(used to indicate data/command mismatch)
