-READ.ME You will not be able to boot this diskette. Boot your PRO8 system from your usual system disk. IMPORTANT: Make a copy of this disk and put it away in a safe place. If you've done a speed-up modification to your Kaypro you may need to switch your machine back to 2.5MHz before using the COPY programs. You may try it at 5MHz but go to the slower speed if you have any problems. When transferring files between different floppy formats and different drive types, it is more efficient to use PIP.COM. This disk contains all the files you will need to use and modify your PRO8 system. Other New Files and their uses..................................... CONFIG83.COM This is your new replacement for the CONFIG program that you got with your Kaypro. It is modified to work with 63k CP/M systems. Use it as you would your old CONFIG. This program also allows you to set configuration data for the PRO8 system. RCONFIG.COM The PRO8 rom Version 3 can support the Micro Sphere RF.COM ram disk. If you have their ram disk see RDISK.DOC RDISK.DOC for information on these files. ************** NOTES ON THE PRO 8 AND 4+ MODIFICATIONS **************** ** CAUTION **** CAUTION **** CAUTION **** CAUTION **** CAUTION ** When working on the drive cables (NEAR THE SWITCHING POWER SUPPLY), please disconnect the power cord from the power jack located at the rear of the cabinet. Switching power supplies are touchy creatures. Drive Idiosyncrasies: Jumper options for most drives are located directly behind or near the drive data cable edge connector. Terminator resistor packs are located near the jumper options and are usually socketed. ************ TEAC DRIVES: ************ Teac drive ribbon connectors are mounted upside down from other drive manufacturers. If you mix Teac drives with Tandon drives the drive data cable may be too short. To jumper the Teacs change the HS option to the HM option. The drive select options are set by DS0-DS1. Drive A: corresponds to DS0; drive B: corresponds to DS1, etc., also remove the IU jumper. ******************** TANDON 101-4 DRIVES: ******************** To set up the jumpers do the following: 1. W9 open 2. W19 closed 3. Jumper on W13 - sets up for 6ms step rate 4. W10 open 5. W11 open 6. W12 open 7. W14 open To jumper drive select do the following: 1. W1 ==> drive A: 2. W2 ==> drive B: 3. W3 ==> drive C: 4. W4 ==> drive D: The onboard processor only checks the jumper options upon power-up so make sure you power down after the jumpers have been set. *********** CDC DRIVES: *********** Make sure the "M" option is jumpered and drive selection is done by jumpering drive number 1 for drive A:; 2 for drive B: and so on. ************************ MITSUBISHI M4853 DRIVES: ************************ Move the HS jumper option to the HM option. Drive select options are DS0-DS3, these correspond to drive A: - drive D: respectively. The terminators are soldered in but there are 7 jumpers located behind the terminator. Removing these jumpers isolates the terminator from the board. 4+ Notes: Teac 55 series are half power drives, therefore four drives can operate off of the KAYPRO power supply with our 4+ decoder board. Tandon or CDC drives (if you add drive C and D) will require their own power source. Make sure you only have one terminator (resistor pack) located on the last physical drive of your system. Exceptions to this statement follow: If you are using 4 Teac 55 drives then the terminator needs only to be on drive D:. If you are using drives (for C and D) that require their own power supply then a terminator is required on drive B: as well as on drive D:. A 600 OHM terminating resistor pack should do the trick. This way when you need to take your KAYPRO and use it independent of your C: and D: drives, drive A: and B: will be protected by the terminator on B:. Decoder Board Installation: Remove the (drive) I/O cable from the mother board at J6. The decoder board plugs onto the exposed male header at J6. The orientation of the decoder board is male right angle pins toward the drives. The micro-clip has to be attached to +5 volts; J5 pin 6 will do. PRO 8 Notes: Kaypro II to 4 conversion: When picking up A11 from U59 DO NOT bend out pin 2, just tack on to the exposed part of the pin. Don't forget to change U73 to the 74S04, this faster part is critical for the select pulse from U72. ** CAUTION ** It is recommended that a 3 wire soldering iron be used on all modifications. This will eliminate the probability of damage to any static sensitive chips you may be soldering on. **** If you are having problems and have an old Kaypro check U82 (the floppy disk controller). If it is a 1793 disregard the rest of this note. If it is a 1791 you must do the side select circuit a little differently. Bend out pin 6 of U73 and solder from this bent out pin to pin 32 of J6. (Before you had jumpered from U73 pad 6 to J6 pin 32. Remove that jumper). Now bend out pin 13 of U72 (the PIO). Jumper from this bent out pin to the bent out pin 5 of U73. (Originally we jumpered to E40, remove that jumper). The reason for this is that the original design of the Kaypro used this line to strobe or test for busy on the unused side of the system port. This arrangement was never used for anything but it tied up that bit on the PIO. We are just avoiding that traffic by direct jumpering.
