GENERAL

SECTION 1INTRODUCTION TO CALCOMP

Cal i fo rn ia Computer Products , Inc . , was founded in 1959 fo rth e purpose of des ign ing , manufac tur ing, and market ing a d ig i -t a l p l o t t e r . CalComp has developed many graphic products andtoday i s the acknowledged world l eader in computer graFhics .GRAPHICS PRODUCTSCalComp's graph ic products today cons i s t of many d i f f e r e n thardware and software i tems covering the complete range ofcomputer graph ics . Products may be conf igured to th e pa r -t i c u l a r needs of cus tomer app l ica t ions .

GRAPHIC SYSTEMSGraphic systems are genera l ly used as per iphera l equipment toa genera l purpose d i g i t a l computer . CalComp systems a re sup-por ted by computers manufactured by major computer companiesthroughout the world . The genera l purpose computer used witha CalComp graphic system i s r e fe r red to as the HOST computer .CALCOMP HARDWARECalComp Graphic Systems are cen te red around a graph ic outpu tdevice (p lo t t e r ) with con t ro l l i ng hardware and opt iona laccessor i e s .

System ConfigurationsA p l o t t e r must be p a r t of a system in order to provide se r v ice . CalComp p lo t t e r s are designed to operate both in of f l ine and online conf igura t ions . Figure 1-1 i l l u s t r a t e sthese tw o conf igura t ions .When th e p l o t t e r i s used in an off l ine system, the p l o t t e rda ta and con t ro l commands are generated by a hos t computerand output to a por table medium e . g . , magnetic tape orpunched cards . The data i s inpu t on a CalComp con t ro l l e rwhich converts the data i n to s igna ls and dr ives th e p l o t t e r .When th e p l o t t e r i s used in an onl ine system (see Figure 1 - 1 ) ,the p l o t t e r commands are output d i rec t ly to a CalComp p l o t t e rthrough i n t e r face e l ec t r o n i c s suppl ied by CalComp or supp l iedby th e hos t computer manufacturer . The p l o t t e r may be connec ted through a CalComp c o n t ro l l e r . The data may no t god i r e c t l y t o the CalComp p l o t t e r in some systems, but may be"SPOOLED" or t ransmi t ted to a Jcerminal to which the p l o t t e ri s connected.

CalComp PlottersCalComp produces the fo l lowing bas i c types of p l o t t e r s :

Electromechanical ink-an-paper p lo t t e r s Elec t ronic /microf i lm p l o t t e r

The elect romechanical p lo t t e r s include drum and f la tbed p lo t t e r s ; each ava i lable in var ious s i zes . The e l e c t ron i c /microfi lm p l o t t e r uses a CRT (cathode-ray tube) with a camera.

Drum PlottersCalComp's drum p lo t t e r s pre sen t computer output data in anunin te r rup ted manner. A continuous se r i e s of g raph ics ,drawings, or maps can be completed in rapid sequence, wi th thepaper advancing under computer con t ro l in to pos i t ion fo r eachsuccess ive presen ta t ion . A se r i e s of p ic tu res can be runsevera l t imes fo r updat ing or addi t ion of new informat ion,because o f the repea tab i l i ty f ac to r . Continuous p lo t s up to120 f ee t in length are produced by the ro t a ry motion of thedrum and l a t e r a l motion of the pen ca r r i ag e .

Flatbed PlottersThe exposed p lo t t i n g sur face o f CalComp's f l a tbed p l o t t e r smakes it poss ib le to view the graphic pre sen ta t ion as it i sbeing p lo t t ed . Fla tbed p l o t t e r s are w el l su i ted to onl ineopera t ion where r ea l - t i me graphic ou tpu t i s r eq u i r ed . Thef l a tbed p l o t t e r i s p a r t i c u l a r l y adapted to automat ic d r a f t i n ga p p l i c a t i o n s . The ' f l a tbe ds ' can handle a var ie ty of p re p r in t ed forms and s p ec i a l mat e r i a l s which normally are n o tp r a c t i c a l fo r pr in t ing and punching in r o l l form. Thisf a c i l i t y al lows fo r easy updat ing of prev ious work or ad d i t i ons to p repr in t ed forms .

CalComp Basic Sof tware conver t s the u se r ' sdata to commands which produce d i s c r e t e , e lec t ron-beam de f l ec -t ions ( r e l a t i v e to the X and Y axes) and i n t e n s i t y v a r i a t i o n son the face of the ca thode-ray tube . The CRT disp lay i s t r a n s mi t t e d through the camera l ens system and recorded on microf i lm . The exposed f i lm may then be processed to produce e i t h e rpos i t ive o r negat ive t ransparenc ies fo r d i r e c t viewing or fo rp r in t i n g in a va r i e ty of processes .

Basic SoftwareBasic sof tware i s a s e t of c lose ly r e l a t ed subrou t ines t h a tgenera te ou tpu t fo r con t ro l l ing a d i g i t a l graphic sys tem. Theprogrammer i s not requ i red to communicate with th e hardware ini t s own data s t ru c t u re . Ins t ead , he communicates with the s e tof subrou t ines in a manner such as :

"move the pen to spec i f i ed coordinates""place some charac te rs a t a cer ta in loca t ion onthe page""draw an annota ted ax is""sca le and draw a l ine through a se r i e s ofpoints"

This kind o f communication reduces the problem of fo rmat t inggraph ic ou tpu t to the l ev e l o f fo rmat t ing the data fo r ap r in t ed r ep o r t .Basic Sof tware cons i s t s of Host Computer Basic Sof tware (HCBS)and Graphic Cont ro l l e r Software (GCS). GCS i s used only inse lec ted systems. HCBS cons i s t s o f those subrou t ines whichare r es iden t on the user ' s computer . Output fo r CalCompgraph ic systems i s produced by var ious types of HCBS. StandardHCBS produces a compact data format while CAL-EDIT HCES pro-duces an ed i tab le format; both used with CalComp e lec t rome-chan ica l p lo t t ing systems. A COM HCBS produces a compact dataformat incorpora t ing the add i t iona l c a p a b i l i t i e s of an e lec -t ron ic p lo t t ing sys tem. GCS i s the sof tware which res ides inth e CalComp programmable c o n t ro l l e r , i n t e rp re t s the appro-p r i a t e data format and dr ives the p l o t t e r .
