Producing PC's thru Lincoln Gerber
1) Write PCP file
(also do INNER and PPLOT if a multi layer)
2) :DRAW2;PCPLT
Modes(?) - type T[LL] for Lincoln Lab mag tape, or
X[LL] for PLX file for :XGP ;PLOT
This will produce a MAG file and LOG file for every
input file. The device is necessary to make aperture
equivalences the same for MAG or XGP
3) Write MAG file on 9 track tape, 512 character (128 word) blocking.
On DM, type ":DRAW2;RAYTH"
"OutAscii/Rec[512]<cr>"
<file-name>
4) Read MAG file back to disk for comparison.
"InAscii<cr>"
<file> TAP
Run MAGGOT over file. (?)
5) :DRAW2;PCPLT
Modes(?) - type Y[LL] to produce drill tape file (DRL)
6) :DRAW2;TD
Rotation ? Flip ? Offset ? Output to DSK
This produces a .PTP from the .DRL file
7) On ML, do :Q AI:DRAW2;PUNCH (can't run punch directly from TD)
Setup paper tape punch, type file name in response to prompt, e.g.
Type input file in Lisp format: (FOO PTP AI DRAW2)
8) When done, quit out of it, and type (YANK). Put tape in reader
and type output file [e.g. ...format: (FOO PTR AI DRAW2) ]
9) When finished, go back to AI and do :DRAW2;PDRILL and
read in DRAW2;FOO PTR. Perhaps do PLOT (.PLX), probably do LISTING (.LST)
Null file name defaults to input first name.
The .LST can be SRCCOM'ed with a .LST generated from the FOO PTP.
