Undocumented Standalone Tests for the 3100

All commands are entered from the '>>' prompt. Each of the commands below are prefixed with a 't '. So, to do the system test, the following would be typed by the user 't a'.

Command         Description

a               System test
b               Display bad memory table (used after m command)
C               Color mask test
c               Cache test
D               DZ test (serial lines)
d               Disk RAM test
e               Ethernet Standard Address test
F               FPU test
f arg           Video test.  Arg is one of:
                     b=blue
                     c=color bars
                     e=screen filled with E

                   type any character
k               Keyboard
L               LANCE chip test (ethernet)
l               LED test
m               Main memory test
n               Network RAM test
P               Mouse test
p               pcc test
R               CSR test
r               RTC test
s               SII test
t               TLB test
V               VDAC test
v               Video RAM test
w               write buffer test
There are also some commands which specifically test various SCSI devices. The command prefix for these is 'scsi '. Prior to issuing any of the commands for specific defices, the 'scsi pb' command must be issued to size the bus.
Command         Description
-------         -----------
pb              Size SCSI bus and configure
cd arg          Canned disk test.  DESTROYS ALL DATA.  The arg is the SCSI ID
ct arg          Canned tape test.  DESTROYS ALL DATA.  The arg is the SCSI ID
cr arg          Canned CD ROM test.  DESTROYS ALL DATA.  The arg is the SCSI ID
(hey, wait a minute, destroys all data on cdroms? somehow I don't think so ;-)
