1-1 PRODUCT SUPPORT.

1-2 This is basically a quick reference manual that will aid both the dea.ler and the user who have general questions regarding the KA YPRO II personal computer. It is not meant to be used as a detailed technical manual or an operator1s manual.

1-3 CRT. (Refer to Figures 1-3 (A) through (D) and Table 1-3).

a. When working on the CRT and associated circuitry, take care not to touch the two metal deflection rings at the end of the neck of the CRT as this will severely distort the display. Also, there is high voltage present, so keep this in mind when making

adjustments. Align the CRT by reaching in and grasping the white taped coil on the neck of the CRT and turning the coil in the

direction required to square its display. Turn the coil a little past alignment, as it will turn back a bit when you release it.

Remember, avoid touching the metal deflection rings at the rear of the neck of the CRT.

b. The controls for adjustments on the video board shown in Figures 1-3 (A) and (8) should normally need no adjustment, as they are aligned at the factory. However, should it be required, they can be adjusted. The names of the adjustments make their uses apparent. Note that the horizontal size adjustment is a coil and requires a special non-metallic tool. This is a delicate

'component, so use extreme care. If the BRIGHTNESS control on the video board is turned up too high, then the raster will be

apparent when the front panel BRIGHTNESS control is turned all the way down.

c. Figures 1-3 (C) and (D) show the geometric distortions possible on the CRT display and their acceptable tolerances.

Figure 1-3 (D) shows an example of perfect video alignment with the capital letter E positioned on the borders. If CRT

adjustments are required, alignment should be made as close to perfect as possible.

d. Table 1-3 lists the video signals on connector J 1 of the main board and the voltages on the video boards. Take care when removing and reinserting the connector on the video board, as repeated removal and reinsertion could loosen the connection. The video signals coming from the main board are separate, not

composite as in a TV signal. Also, one easy way to see if you have the 12V on the video board is to turn up the BRIGHTNESS control on the board and see if you have a raster by turning the front panel BRIGHTNESS control all the way down.

e. The display will jiggle on the CRT if the video drive lines are too near the flyback or the power supply. If this is the

case, physically move them away, and the problem should disappear.

1-4 DISK DRIVES. The disk drives should require no maintenance other than occasional cleaning, using disk cleaning systems avail-·

able from your local computer supply store. However, if you should work on the disk drives, take care when handling their connectors, as the pins are easily damages. Figur.e 1-4(A) shows how the disk drives are jumpered. Drive A has pins 1 and 14, and pins 2 and 13 jumpered in location lE, while Drive B has pins 1 and 14, and pins 3 and 12 jumpered in location 1E. A terminating 150 9hm resistor pack is in location 2F in the drive attached to the last connector at the end of the drive ribbon cable. There is no resistor pack . in location 2F in the other drive. The disk drives are shipped with white disk head protectors, and these should be in place in the drives upon receipt of the computer. When returning faulty drives to the factory, the disk drive head protectors must be in place, or else the warranty is void.

1-5 KEYBOARD. The 76-key alphanumeric detachable keyboard is connected to the computer by a four-wire cable (refer to Table 1-5 for pinouts) and is powered by +5 VDC through the cable. An easy way to tell if your keyboard has power or not is to depress the CAPS LOCK key and see if the red LED indicator lights. Use the cable that is supplied with the computer, as different cable

lengths cause a mismatch of impedance which can result in

problems. Especially do not use phone cords as they are typically not low enough impedance. Incorporated in the keyboard is an audible device which beeps or clicks as indicated (on tlow to

defeat the clicking see The KA YPRO II User1s Guide: Sample S-BASIC program in the appendix). The keyboard uses the standard 7-bit ASC II characters, with special functions available by use of the

14-key pad to the right of the standard keys and the four arrow keys.

1-6 POWER SUPPLY. The power supply used in the KA YPRO II computer is either a California DC power supply or a Boschert

power supply. Both supp~):' .plus and minus regulated 12 VDC and +5 VDC and dissipate approxhnatefy 60 watts. One important

difference between them is that the Cal DC power supply has two five-watt power-dissipating resistors located in the upper corner (these are the 1K & 10K Ohm rectangular ceramic resistors) that normally get quite hot. Therefore, the power supply cables nearby should be tied down behind the power supply circuit board, or damage could result. There are two fuses associated with the power supply: one (2 Amp) accessible on the back panel of the KAY PRO II, and the other (3 Amp) on the power supply board. If work is done on the power supply, make sure that the plug is oriented correctly when reconnected, with the black wire on top and the white and green wi res underneath. To change the power supply from 110 V AC to 220 VAC, refer to Figures 1-6 (A) & (8).

2-1 REFERENCE INFORMATION. Several figures and tables are included as reference information. They contain a variety of

useful information concerning the KAYPRO II, including control key sequences, main board component locations, and video control

codes.

2-2 Changing Baud Rate. The KA YPRO II has a RS-232C serial port (J 4) to interface with external devices. Both the computer and

the external device must be set at the same baud rate (tne speed at which data travels). To get the baud rates listed in Table 2-2, output the HEX value listed to port

o.

2-3 I/O Pin Connections. Table 2-3 lists the pin numbers and . designations for the RS-232C connector labeled IIJ4 SERIAL 1/0."

2-4 SERIAL PORT ASSIGNMENTS (refer to Table 2-4).

For modem (serial channel A) : PORT 4 is the Z-SO SIO data port.

PORT 6 is the Z-SO 510 control and status port.

Received character available is obtained by testing bit 0 of the status port; Transmit Buffer Empty is obtained by testing bit 2 of the status port. Other details can be found in the Z-SO

documentation available from Z ilog •

For defeating handshaking on the RS-232C connector:

Pins 5 and S are jumpered to pin 6.

To tell CP /M to reconfigure output from parallel to serial interface, enter on keyboard the following:

STAT LST :=TTY : (This process can be made permanent on a diskette by using CONFIG.)

The serial output is an S-bit word with one start, one stop, and no parity.

3) Machine works short time-- 1) U 88 bad then dies (no boot, no reset)

When suspecting bad video, put two computers back to back and swap video cables from one to the other. This will help determine where the problem exists.

When the problem is with the disk drives, keep in mind that it may look like a bad drive, but it may be due to something else. It is best to approach any problem in a logical manner. First, check to see if the Read IWrite protect slot on your diskette is taped. If it is, then you won't be able to write onto the diskette. Second, your diskette may be bad, so try a known good one. Next, if you suspect a disk drive, then you can restrap them to narrow down the problem (i .e. change

"B" to "A" and vice versa). See paragraph 1-4 for more information.

Check to see if the drive is turning inside. Also, are the LED s on or not? All of this will help· determine where the problem may be.

*Note: There are some versions of the liB 111 main board out in which U2 and U67 are not CMOS ICs, but regular TTL ICs as in the nAil main board (see Table 2-1 (B)). This is the way those particular liB 111 boards were designed. So read the number on an IC to be certain

of the correct replacement. ~/

Page '17

The following table lists only the differences between the two versions of the main board in regard to integrated circuits--that is, between main board (81-110A) and main board (81-110Bl). The main board number can be found on the side of the main board opposite the com- ponent side in the corrier where the connectors are. The IC s Iisteu below are those which are found on the ^II A" main board that are dif- ferent from those similarly designated on the liB 1" main board (see Table 2-1 (A». An asterisk "*" following an I C designation indicates that chip is present on "A" main board, but not on the "B 1" main board.

KAYPRO II TECHNICAL NOTE: Video software driver

The KA YPRO II video section was designed to imitate the control sequences of a Lear-Siegler ADM-3A terminal. For most commercial software this means you can "install" or customize the display char'ac- teristics by choosing the ADM-3A from an install /config menu. For custom software or those instances where there is no choice of "ADM-

3AII on the menu, the following information may help~
