This library contains the executable program used to "park" the heads on hard disk drives. This program must be "patched" with the cylinder number that the heads are to be positioned over. The program supports two hard disk drives connected to the WD-1002 hard disk controller. The 8080 assembly language source for the TURBOSAF program is included. Notes are included in the source on how to patch the executable version (TURBOSAF.COM). Before using this program you must customize it for the Winchester Drive(s) that you are using. Failure to do this could cause damage to your hard disk. Not all hard drives have a dedicated shipping zone for parking the heads. If your drive does not then simply wait till the select light goes out and turn your machine off, there is no benefit in running this program. Of the three drives that are available from Plu*Perfect Systems for use with the Advent TurboROM, two do have such shipping zones but this is atypical. Shugart 604 has shipping zone at cylinder 180 Rodime 252 has no landing zone and it is impossible to seek beyond cyl 305 Seagate 225 has shipping zone from cyl 615-670 Use your text editor (WordStar in non-doc mode or Perfect Writer) to edit the equates in the source file to match your situation. Then assemble it using ASM which is supplied with your CP/M system. "ASM TURBOSAF" (This takes the file TURBOSAF.ASM and generates a file TURBOSAF.HEX.) Generate a COM file with LOAD which was also supplied with your CP/M system. "LOAD TURBOSAF" (This takes the file TURBOSAF.HEX and generates a file TURBOSAF.COM.) You can now run TURBOSAF before shutting down your machine. Appropriate zones are: ST225 = 650 RO252 = 305 doesn't do anything SA604 = 180 TURBOSAF is supplied by Advent and Plu*Perfect Systems to support the hard disk drive added to a Kaypro computer with the TurboROM installed.
