Fuctional Block Dia gr am ww L J I I I 5toraKe r- -- r----' Select Circuitry I I I us eu The POP is a state-o f-the-art microcomputer. It rec eives instructions for the opera tion of differen t ga mes fro m individual Read-Only-Me mory (R OM ) game c artridges. The POP in terprets data from the .;ame con t rolle rs and executes comma nds on t he te levision screen. Figur e I-I is a bloc ". diagram of the functional flo w of the PO P. GAME CONSOLE The POP board sets in a me tal enclosure tha t shie lds the mainboard fr om rad iating · e lectron ic noise which originates in the telev ision set. AT ARI ves PO P Field Ser vice Manual 1-1 MAINBOARD • m. co m Th e mainboar d is a Prin ted Circuit Board (PCB) wh ich holds th e po wer supply, the RF modulator, the microprocessor (M P U) c hip, a combinat iu,' Random Access Memory Input/Output (RAM-I/O) chip, and a Television Interface Adaptor (TIA) chip. The board also includes numerous capacitors, resistors, tran3istors, and other assorted electronic components. Po wer Supply • RF Modulator us eu The power supply is composed of a +5 vo lt regulator, filter capacitors, and the power O N/OFF sw itch. Unr eg~ lated DC is supplied to the logic po rtion of the PCB fr om t he AC power adaptor. A suppy of +5 is routed thro ugh a filter circuit to the RF modulator. Th is reduces the a mount of RF radia tion generated by t he ga me. The RF module converts the signal r e ceived from the Telev ision Interface Adaptor to a frequency t hat a telev ison can r eceive and int erpret. A coaxial cable passes this signal from the RF module to the c able mounted t o the oack of the television. • Microprocesso r Chip • ata rim The 6507 Microprocessor (MPU) ch ip is an 8-bit microprocessor that is re sponsible for the coordination of all circuitry in the POP . It c ontrols and monitors t he functions of t he RAM and the TIA, reads informat ion from the ROMs and instruc ts t he TIA in what to disp la y. Random Access Me mory-Input/Output Chip • w. Temporary storage of data from the MP U is prov ided by the 6532 Random Access Memory-Input/Output (RAM - I!O) chip. This ch ip scans the I/O joystick lines for input. It also kee ps track of the internal timing of the chips for accurate video coordination.! Television Interface Adaptor Chip ww This ATARI proprietary c hip genera tes audio and video signals which are r equired by t he RF modulator. The TIA a lso contains the analog-to-digital c onverter circuitry that allows the MPU to understand signals originating in the paddle game controllers and to keep track of all player missiles a nd c ollision registers. The TIA outputs are proc essed by additional Circuitry in to a composite v ideo, sound and color signal which is routed to the RF module. It also generates the Sync signal for the unit. • Color Circu it The master oscillator consists of a c rystal, t wo transistor s and additional circuitry which oscillat e at a frequency of 3.57 MHz (plus or mi ,'us ,004). ATARI VCS POP Field Se rvic e Manual 1-2 SUMMARY m The POP is a micc oco mp uter tha t enables the user to sele c t any o f the ATARI ROM cartridges ins talled on the PCB and pla y it for a predetermined period of ti me. ww w. ata rim us eu m. co Three c hips on the mainboard allow for the interaction bet ween the game and the playe r. These chips are t he microprocessor (MPU), t he Random Access Me"mo ry Input/Output (R AM-I/O) and the Television Interface Ada ptor (TIA).

I. The POP Ga;ne ROMs must be modified according t o POP ROM Modification, page I (part nu mber FDI00029 ), regarding placement and /o; replacement of Game RO Ms. This ensures t hat you are not repairing ,. game RO M wh,ch is to be la ter re moved. 2.

I) Zener Diodes (lN37 47 - COl7654) two each. 2) Capacit ors (.0047uf - COI4180-08) two each. ww 3) Masking compound. B. Attach the Zener Diode t o t he capacitor (See figure 3-U. Make c e rtain that the polarity is correct. C. Make certain the holes into wh ich the assembly (built in Figure 3 .1. ) . ·is to be inserted are clear of all solder . D. Insert and solder t he two assemb lies (built in Figure 3- 1) into the two locations indicated on the POP PCB (See Figure 3-2). E.

The screen should be steady and unchanging. A gray or blue horizontal reference line extends across the screen about four bars from the bottom. This reference line is thinner than the bars around it. R7 0 ;hould be adjusted to t he bars immediately above and below the reference line co within one shade of each other. (The bars should be goldenrod in colo<.) Proper operation of the unit is indlcated .by being able to make this adjustment and by consistent co lor within the entire span o f each bar on the screen. Minor glitches on the edges of the color bar are acceptable. Leave this test on for at least 60 seconds in order t o catch any intermittent pr oble ms, such as a bar momentarily changing colors or b lank ing out. us eu m. co m • *** NOTE * ,. * ww w. ata rim Figure 3-6 is a black and white re presentation of a color telev ision screen.

They are a ll very sensitive to stat ic elect ricity and can easily be erased by careless handling. Always keep the chips in the ir plastic carr ie r t ubes or on conductive foam when not handlinlC them. Make certain you are well grounded when handling t he c hips. Atari stronglY recommends that you wear a conductive grounding band (whic h ties from your arm to ground) when handling the chips. The chips are also suscept ible to damage from stress when being removed from or in serted into the sockets. Alw ays use a chip puller when removing the chips. Do not pry the chips out with a screwdr iver or a ny other tool. ww w. Failure to follo w the above guide lines resu lts in unusually high chip failure rates and extra expense.
