1-1 '!be in:fbrmation and procedures covered by this manual assume sane technical krlc:Jwledge on the part of the reader.
'!be J;X>licyof Kaypro Corporation is to repair computers to the modular level only. ENen Kaypro1s repair technicians do not repair switching power supplies, CRl' assemblies, or disk drives. Repairs to Irodular oomponents not manufactured by Kaypro Corporation (J;X>Wer supplies, CRI' assemblies, disk drives) are Nor oovered by this manual.
H:>wever, we do not discourage dealers and technicians who have the knowledge and the tools to repair to the compalerlt level :from doing so, on out-o f warranty Kaypro canput.ers. '!be adjustment am rerroval/replacement in:fbrmation in this manual is organized by module type, with the exception of reIOOVal/replacement infbrmatioo 1br the KAYPRO RCBIE, which is placed in a separate sectioo due to the di fferences in chassis design and hardware module placement in that machine.
1-2 As Kaypro keeps in step with oomputer technology, the models have changes which a ffect FCC ratings. 'nle proper rating is a ffixed to the back of each oomputer. Caltact the Kaypro Engineering Department if you need further in1brmation.

Turn off the machine. 2. Disconnect AC power by unplugging the power oord :from wall outlet. 3. Remove the ten screws :from the chassis hood: there are two on top and :fOur on each side. 4. RsIove the hood :fran the chassis. 1. IDwer the hood onto the unit. 2. Align the two holes on top of the hood with those on top of the chassis. 3. Insert the two flat-head screws into the holes on the top of the chassis and start them, but do IDt tighten them yet. 4. Insert the eight round-head screws, :fOur on each side, and start them. 5. Tighten each screw securely. 5-1 Kaypro Corp:>ratioo has small amounts of touch-up paint fur Kaypro hoods and chassis available to the dealers. Contact the Hardware Technical Sugx>rt personnel to obtain this paint. O:::casionally a customer's computer will have scratches on the hood or chassis. A small amount of rubbing compound, when carefully applied, will often smooth out very small scratches on a hood or chassis. Should painting be necessary, there are two sizes of sable paintbrushes to have CD hand: size 00 and size 000. 'Ihese brushes are available at any art supply store. 5-2 6.0~ '!he :fOllowing sections contain schematics, chip layout diagrams, and IC lists (by U-number) :fOr Kaypro mainboards. 'nUs is not intended to be a theory of operation, but rather an aid to locating possible problems on a mainboard. Consult an appropriate databook (TrL, Zilog, etc.) if you need to find out the internal \t.Orkings of a particular IC. MAINBCNID TRClJBLESHoorING TIPS: A blank EPRCM can be used to help troubleshoot Kaypro mainboards 0 f series 81-1112J, 81-240, and 81-100. '!he appropriate roodel of EPRCM (2732, 2716, etc) allows a quick check of the board. It will usually :fOrce the data and address lines to toggle" at approximately the same amplitude, allowin;;J the technician to use a scope to spot affected lines. I f the video display does not show a screen filled with alternatin;;J "g"ls and apostroJ;:hes, you have a problem in the video RAM or associated circuitry. You can check the main RAM and associated circuitry quickly with a scope by lookin;;J at pin 14 on each of the RAM chips. There should be a pattern of signals like this: For the 81-240 board: U212J (D7) lC711 U21 (nG) lC711 U22 (Ds) toggle U23 (D4) toggle U24 (D3) toggle U2s (D2) lC711 U26 (Dl) lC711 U27 (00) toggle '!he U-mnnbers of the main RAM chips will vary dependin;;J on which mainboard you have, but the pattern will be the same. 6-1 I 1 21.

A group of video signals (CCf2J through CC3) are includErl as illustrations of the timing relationships between the various video signals. Note that only one of the I/O signals on U57 will be low at any given time. State of the machine: The door of drive A is open: the machine is waiting to boot. The signal measurements were made using a Tektronix oscilloscope, model 2213. It has a bandwidth of r.c-6f2J MHz, sensitivity of 2mV/em, a sweep delay of f2J.l microseconds to 1 second, and a graticule display measuring 8 x lf2J em. Signal Ml from pin 27 of the cru (U63) was triggerEd on. This signal is shown in the top half of each display and was channell. Ground for the signals shown on channel 2 was established at first graticule line above the bottom of the display. Each square of the representation is the equivalent of one square em on the graticule. The scope was set for 'N/div. for all figures, am. was set for .5 micro-sees/dive for all figures EXCEPl' figure 6, which was taken using 1 micro-sees/dive - Figure 1: Pin 6 of U63, 2.5MHz clock signal.

A group of vide::> signals (a:0 through CC3) are included as illustrations of the timing relationships between the various vide::> signals. tete that only ~ of the I/O signals on US7 will be low at arr.t given time. State of the machine: with a blank, 2732, EPROM inserted in place of IX>rmal EPROM at location U 47. The door of dr~ve A is open: the machine is waiting to boot. The signal measurements were· made using a Tektronix oscillosoope, model 2213. It has a bandwidth of OC-6f2J MHz, sensitivity of 2mV/em, a sweep delay of f2J.I microseconds to 1 secald, and a graticule display measuring 8 x lf2J em. Signal Ml from pin 27 of the CPU (U63) was triggered on. This signal is shown in the top half of each display and was channell. Ground for the signals shown on channel 2 was established at first graticule line above the bottan of the display. Each square of the representation is the equivalent of one square em on the graticule. '!he soope was set for 'lV/dive for all figures, and was set for .5 micro-seeS/dive for all figures EX.CEPl' figure 6, which was taken- using 1 micrcrsecs/div.

Because of the number of manufacturers from which Kaypro gets its diskette drives, no attempt is made in this manual to show alignment procedures fur each of the drives. If you have access to a drive manual fur a particular model, and have the Dysan Alignment Diskette (Dysan's part number: 224/2A) the knowledge, and an oscilloscope, go ahead and align away. Kaypro Corporation's policy is to do no repairs on these components. Ibwever, since the company recognizes the fact that many customers want a KAYFRO computer in which both drives have the same outward appearance, we provide a guide fur determining models of diskette drives from the placement of the LED and the drive door closure. This section also contains diagrams and instructions on jumpering the various models of diskette drives to be used as either A or B (or, in the case of the KAYFRO 10, C) drive. DISK IIUVE CLFANING Generally speaking the majority of people clean disk drives too often. l.hless the environment is especially dusty or dirty, under commercial use there is 00 reason to clean the drives more than twice a year. Use care in selecting a cleaning kit. Many of the drive head cleaning kits on the market are very abrasive.

As with the diskette drives, all models of hard disk drives are :functionally interchangeable. No adjustments are meant to be made by dealers (or are made by Kaypro technicians, :fOr that matter) on these hard drives. And, since recovering in:fbrmation from a hard disk which has "crashed" requires a clean room, I'X) direct.ioo.s :fOr per:fbrming such an operation are incl1.~ed in this manual. Be aware that true head crashes are very rare occurrences, however-most hard disk problems can be corrected without the need to replace the drive itself. (See the symptom-fix guide.) We cannot stress strongly enough that dealers instruct their customers to ALWAYS back up their data while working on a hard disk. In many cases NOl'HING can be done about the loss of data in a hard drive failure. 10-1 1.8.2 liB::RIPrI '!he hard disk drives used in the KAYFRO 10 are irrlustry standard, 5-1/4 inch half-height drives offering Winchester. technology.
