                    INSTALLATION INSTRUCTIONS FOR TurboDOS




Th堠 COLEX-88 famil computer requir th usua precaution fo al 
computer installations.



A)   Computer System Chassis
     
     Some specific areas to pay attention to on the computer itself are :

     -    Good quality power supply 

          Voltag dip o spike fro nea b heav machiner (suc a 
          elevator o powe tools ma cause th compute t sto i           
          extrem cases.

     -    Good air flow

          B sur tha th botto an bac sid o th compute ha enoug 
          spac fo fre ai flow  Th ai intak i fro th bottom thi 
          shoul b a coo a possible.

     -    Good grounding

          B sur tha  grounde powe cord an grounde powe outle i 
          used to shield the system from external noise.          

     -    Accessable location

          Sinc th flopp dis wil b us  fo archieva storag o data a 
          wel a fo exchang o dat wit  othe systems th flopp dis 
          driv mus b easil accessable.

     -    Dust free, Dry environment

          Dus buildu o hig humidit wil caus th compute t fai i 
          extrem cases  Th Compute shoul b locate i  dust-fre 
          locatio (Preferabl no o th floor wher n wate o 
          condensatio  ca ente th syste chassis.







B)   Peripherals

     Th COLE compute i designe t wor wit rang o standar compute 
     peripherals.

     1)   Terminals
     
     An Vide displa termina usin  "RS232 o "V24 interfac ma b use 
     wit th system  Thes terminal ca b locate u t 5 meter fro th 
     compute system.

     Th COLEX-88 require tha DT (pi 20 i activ (+7V fo dat t b      
     outpu fro th system  I th termina doe no hav  DTҠ output       
     the a activ "DTR mus b simulated.

     Not tha th standar TurboDO syste expect DT t b use t contro 
     th flo o dat  t  terminal I  termina canno proces dat a      
     th spee i i sent  i shoul mak DT inactiv t sto dat fro th      
     CPU.

     Th recommende spee (bau rate i 19,20 baud  Othe speed ca b 
     accomodate a a option  XON/XOF dat contro i als possibl a a      
     OE option.


     2)   Parallel Printers

     Th syste support  paralle printers  Thes shoul b Centronic      
     compatible  Th distanc fro th printe t th compute shoul b 
     limite t 1 meter o cabl length  Th syste ca suppor  paralle           
     printer a th sam time.


     3)   Serial Printers

     On seria printe ma b connecte t th syste fo eac terminal  Th 
     seria printe cabl an DT requirement ar th sam a th vide 
     terminal  Th bau rat i se a 120 baud  XON/XOF dat contro i 
     no supported.
