1. Once you have entered Applesoft and initialized the Cluster One interface you should not need to issue the CALL 51712 command except for the following circumstances If you intentionally Or accidentally press the RESET button on non Apple II Plus systems and get to the Monitor the proper procedure for reentering Applesoft is to type cntrl C return If you use cntrl B you must reenter the command CALL 51712 as described in Section III B 2 3 Radio Shack TRS 80 On the TRS 80 there should be no normal sequence of events where you must reinitialize the Cluster One interface If necessary for some reason you should first turn off and then on the TRS 80 and proceed according to the procedure shown in Section 11 8 3 Note that the Cluster One interface must be reinitialized whenever you enter DISK BASIC from TRSDOS I This section describes the steps to be taken if there is no response to a Drone command after a reasonable amount of time has elapsed l First check to see that the Cluster One system is running This can be observed by looking at the console diagnostic display which should show the usual rolling letters in the POLLING row with occasional pauses for servicing Drones If this is not the case notify the System Administrator who will analyze the situation and restart the system 2 If the system appears normal and others can issue commands and are receiving the normal responses first reset y2. 01 see odd error codes above i VII A Disk organization Cluster One disks are physically recorded in IBM standard Single density format with 16 256 byte sectors on each of 77 tracks per side The logical organization of the disks is unique to the Cluster One and the details of that organization need not be known or understood by the user It is not compatible with any other file system from other manufacturers such as CP M The disk consists logically of two parts the directory which describes the types sizes and locations of files on the disk and the file area which contains the files Management of the space within the directory and file area is done entirely by the Queen The limits on number and sizes of files depends in part on that organization and may change with subsequent releases of the Cluster One operating system Current limitations are as follows single sided double sided disk disk Number of files 127 255 Total number of 1216 2432 file blocks Each block contains 256 usable bytes Files are currently stored contiguously so occasionaly a file cannot be saved although there are enough free blocks Future releases may eliminate this problem in the meantime the MERGE utility Section VIII C can be used to compact the file area and produce a single contiguous free area Each file on the disk is of a particular type indicated by a single character The following types are of particular intere
