- Installing TeX on a single-drive ST

- Being the continued adventures of a TeXhacker

-
- The TeX installation described in my TeX First-Aid article was
- developed on, and described around, an ST system with two disk drives.
- Configuring the program on a single-drive system has proved more
- difficult: this article is the result of the experience of some users
- brave enough to attempt a single-drive installation, and of
- experiments conducted since the publication of the first article.
-
- The INITEX and TEX programs are somewhat sensitive to disk changes
- while in operation, even if the 'logical' drive B: is used in the TeX
- setup files. In particular, if errors occur in INITEX, and a new disk
- is inserted to receive the result of the \dump command, portions of
- the format file appear to be overwritten with chunks of the output
- log file. So, first rule - if you are attempting to install on a
- single drive system and INITEX throws up any error message at all,
- type <x> to abort the generation - it is not worth persevering.
-
- Second rule (and this goes for installing on a double drive system
- also) - INITEX must be run in the same memory space as the final TeX
- installation will have. Running INITEX in a full megabyte of memory
- will result in a TEX installation which will not cohabit with a
- RAMdisk. The minimal LaTeX installation appears to require about 700k
- RAM, so before starting to install TEX, set up a RAMdisk of c250K.
-
- TeX and LaTeX installation pre-load a number of the basic fonts into
- the resulting format files, so the TeX font metric files (extension
- .TFM) need to be available to the INITEX program. There is a problem
- of space on the LaTeX building disks in particular, but with a RAMdisk
- available, this is no problem: simply unpack the TFM files into the
- memory drive. So (for example) to install LaTeX, you should have the
- following:
-
- RAMdisk:
- \TFMFILES
- *.TFM - all TFM files
- (TEX2:\TEXINPUT\TFM\TFMFILES.ARC)
-
- Base TeX disk:
- \TEX
- \TFMFILES
- *.TFM (as above)
- \STDIN
- *.TEX (TEX2:\TEXINPUT\STDINPUT\STDINPUT.ARC)
- *.STY
-
- TeX format file creation disk:
- INITEX.TTP (TEX1:\TEX.ARC)
- TEX.POO
- TEXSETUP
- LPLAIN.TEX (TEX2:\TEXINPUT\LATEX\LATEX.ARC)
- LPLAINO.TEX
- LATEX.TEX
- LFONTS.TEX
- EHYPHEN.TEX (TEX2:\TEXINPUT\HYPHEN\HYPHEN.ARC)
- TEX\
- (empty directory to keep INITEX happy)
-
- Edit the file TEXINPUT so that all entries with drive/path indications
- have the value A:;, except for the entry tfmpaths which should
- reference the RAMdisk directory to which the TFM files have been
- unpacked (e.g. tfmpath=M:\TFMFILES;), and the \dumppath entry, which
- should reference A:\TEX. Load the shell you are using, then place the
- format creation disk in the drive, and type the following:
-
- INITEX LPLAIN
-
- After a number of information messages, the system should come to rest
- at a <*> prompt. If an error message appears, stop (type <x>) and
- check that the disks are properly set up and that the TEXINPUT file
- has the correct entries before trying again. Assuming that you are
- safely at the <*> prompt, replace the disk in the drive with the base
- TeX disk and type \dump<return>. More disk activity, more screen
- messages, and (all being well) a file LPLAIN.FMT in the TEX\ folder of
- the base disk will result.
-
- Note that to use TeX on a single drive system may require some
- juggling of disks and files. With a disk formatted to 820k, with the
- LaTeX format file, TFM files and one or two LaTeX styles, there is
- about 300K disk space free: just enough for the LKURZ source and
- resulting DVI file, for example. Viewing and printing the files will
- require copying the DVI files to the appropriate printer or screen
- font disk: on my NL10 font disk there is about 138K free, which again
- is enough space for LKURZ.DVI.
