FileStore Service Manual 113
Checking the test equipment (validation)
Equipment required
(1) A known working FileStore.
(2) This document and the equipment called up in Equipment required, above.
Validation procedure
(3) Set up the equipment undergoing validation (EUV) as described in Connecting the test
station above.
(4) Connect the known working FileStore as described in Connecting the UUT, above.
(5) Cycle through all the tests in FServTest five times.
(6) If the EUV fails any of the tests it must be repaired and the whole assembly retested
from the beginning of this procedure.
(7) If the EUV passes all the tests it may be considered sound.
Modifying the test software
If it is necessary to modify the programs for any reason, it is most easily done with a Second
Processor, connected to the ‗Tube‘ port of the Master Microcomputer. This should be
attempted only as a last resort and after Acorn Computers Limited have been contacted.
WARNING
Any changes made to the test software without the written approval of Acorn Computers
Limited will not be supported and are carried out entirely at the risk of the modifier.
The programs as provided are in a highly compressed (‗crunched‘) form, so they are not
particularly easy to change (although in absence of a second processor, there is no choice).
The directory S.source contains the programs as they were before they were crunched along
with a file called DoCrunch that generates the compressed versions. (Type ‗*exec docrunch‘
- this uses the programs HiBASIC and Crunch from the directory S. Library.)
The test software is provided on a 5.25‖ disc and contains the following files:
!Boot Start-up file
ReadMe A summary of the test software programs
FServMenu Main menu, used to run the other programs
FServCMOS CMOS RAM editor
FservCopy Sector-by-sector disc duplicator
FServEdit Disc structure editor
FServFmt Formatter for FileStore hard discs
FServInit Initialiser for FileStore hard discs
FServSoak Disc and Econet soak tester
FServTest E01S circuit board tester
FSDB Machine code for use by FServSoak
P1 Parameter file for use by FServSoak
Library Library containing system utilities
source Directory containing ‗uncrunched‘ source
