- SCRAM 500 CAD PLOTS
- ===================
-
- In the directory "PLOTS" you will find a file PLOTS.lzh. This arc
- file contains all 12 engineering drawings for the SCRAM 500 in a
- compressed form. The files are all standard HPGL files and can readily
- be printed on a dot matrix printer using the PLT: device - see the PLOT
- directory. HPGL files are fairly bulky and the arc file will blow up to
- nearly 1.5Megs! The files to be found are as follows:-
-
- scram_500_sch1.HP Schematic Diagram 1 of 3
- scram_500_sch2.HP Schematic Diagram 2 of 3
- scram_500_sch3.HP Schematic Diagram 3 of 3
- scram_500_ovly.HP Component overlay
- scram_500_comp.HP Component side tracks
- scram_500_sold.HP Solder side tracks
- scram_ext_comp.HP Component side extender card
- scram_ext_sold.HP Solder side extender
- scram_box_frnt.HP Mechanical drawing front panel
- scram_box_back.HP Mechanical drawing back panel
- scram_box_tube.HP Mechanical drawing extruded case
- scram_box_assy.HP Assembly drawing for main board incl. extender
-
- The files were archived with lz - Jonathan Forbes, Xenomiga Technology.
- And a damned fine job it does too! The format is lzh which gives high
- compression.
-
- PLOTTING HPGL
-
- A lot of information about the SCRAM 500 design is in the form of
- Engineering drawings and CAD plots. The only practical way to distribute
- these is as plot files which can be transformed to HardCopy for perusal.
- The format I have chosen for this is HPGL - the standard plotter
- language. HPGL (Hewlett Packard Graphics Language) is accepted by just
- about any pen-plotter and some laser printers and failing that the Amiga
- can print them using the PLT: DEVICE. See the PLT.lzh file in this directory
- on this disk. There is also an excellent IBM PC shareware program called
- "PrintGL" which does the job. If you haven't used your printer as a
- plotter yet, I think you will be amazed at how versatile it can be. Even
- a lowly 9 Pin FX 80 type dot matrix will render stunning graphics plots.
- I use a 15" wide DX2200 (9 pin) printer and regularly turn out great A3
- schematics. A 24 pin or bubble jet will do even better.
-
- The PLT: device will print out sideways and can scale the drawings to
- any size. If you have a 9" printer (or Laser printer) the plots will
- come out on an A4 sheet landscape. If you have a 15" printer, fiddle
- with the MaxLength parameter for PLT: (see docs) and shove in an A3
- sheet lengthways. You will get great A3 plots. The PLT device will also
- plot a preview to the screen. This can be very entertaining.
-
- SCHEMATICS
-
- Full working schematics for the SCRAM 500 are to be found in the three
- files - scram_500_sch1.HP, scram_500_sch2.HP and scram_500_sch3.HP.
- These files are Plot files in standard HPGL Plotter Language. Due to the
- complexity of the schematics this is the only practical way to
- distribute them.
-
- OVERLAY
-
- The component overlay for the SCRAM 500 main PCB is in the file -
- scram_500_ovly.HP. This file is also in HPGL.
-
-
- PCB
-
- The track plots for the SCRAM 500 are contained in the HPGL files
- scram_500_sold.HP and scram_500_comp.HP. These files are provided mainly
- for interest, however some intrepid soul may want to try and etch them.
- I wouldn't advise it as some tracks are .01" on a .01" grid. If someone
- is really interested in doing a production run of boards they should
- contact me - Gerber files and Excellon Drill files are required.
-
-
- EXTENDER
-
- The files scram_ext_comp.HP and scram_ext_sold.HP are the component and
- solder sides of the extender card.
-
-
- CASE
-
- The files scram_box_frnt.HP, scram_box_back.HP and scram_box_tube.HP
- show how the case is constructed. The file scram_box_assy.HP is a
- cross-section of the SCRAM 500 and case showing how the whole thing fits
- together.
-
-
-
- By the time you have plotted all these files, I think you should have a
- fair idea about what the SCRAM will look like.
