LocoScript
LocoScript was the word processor bundled with the Amstrad PCW. There were four major versions for the PCW, and two for MSDOS.
8-bit versions:
- LocoScript 1 (1985) was bundled with the Amstrad PCW 8256/8512 (3" drives) and PcW 9256 and 10 (3.5" drives).
- LocoScript 2 (1987) was bundled with the Amstrad PCW 9512 (3" drive) and PcW 9512+ (3.5" drive), and was a common upgrade for the other models.
- LocoScript 3 (1993) was only available separately. It added semi-scalable fonts.
- LocoScript 4 (1996/7) was only available separately. It added support for images (in MDA format) and colour printing.
Most PCW documents, on either 3" or 3.5" floppy discs, are thus likely to be in LocoScript 1 or 2 format.
(The PcW 16 did not run LocoScript.)
While standard LocoScript had a relatively wide range of characters, there were some specialised versions for particular scripts, such as Euro-Arabic LocoScript.
PC versions:
- LocoScript PC (later LocoScript PC Easy)
- LocoScript Professional
File formats
Each major version of LocoScript changed the file format. Newer versions could read files from older versions, but not vice versa.
- LocoScript 1 is relatively well documented.
- Schneider PC International 1988/01 (pp84-97) has a fairly detailed description of the LocoScript 1 format (in German), and provides Turbo Pascal source for a program LOCOCONV to convert it (updated in the 1988/10 issue, pp92-97). Versions of that program exist in various places:
- Werner Cirsovius' site (on Wayback machine) had a copy. Wayback Machine doesn't have all the code, but the whole website is archived as a .7z here.
- A modified/translated version is on Frank van Empel's site (search for LOCOCON).
- Another, briefer description of the LocoScript 1 file format (in English)
- The character encoding used for the text portions is the Amstrad CP/M Plus character set, except that the C1 controls range was used for control codes (different ones from the C1 control standard, which probably didn't exist yet) instead of the box-drawing characters of the CP/M Plus set.
- Schneider PC International 1988/01 (pp84-97) has a fairly detailed description of the LocoScript 1 format (in German), and provides Turbo Pascal source for a program LOCOCONV to convert it (updated in the 1988/10 issue, pp92-97). Versions of that program exist in various places:
- LocoScript 2 and up: no known descriptions (although plenty of software exists to read them). These versions had a greatly expanded character repertoire, more than can fit in a single-byte character set. They share some of the same basic structure as LocoScript 1.
- Reportedly, Locomotive/LocoScript Software did produce format documentation for at least Loco 3 and 4 documents, the latter called The Structure of LocoScript 4 Documents and released under NDA; they don't seem to have made their way online. Refs: David Langford's columns in PCW Plus 114 (March 1996) and PCW Today issue 8 (Winter 97/98).
LocoScript documents did not have a conventional file extension. The default filenames it suggested were DOCUMENT.000, DOCUMENT.001, etc.
Converting LocoScript documents
Probably the most difficult problem with converting LocoScript documents into more readable formats is not the conversion process itself, but the fact that the majority of LocoScript files were stored on 3-inch floppy disks, which are now difficult to access. See the linked page for ideas for how to deal with this.
LocoLink (and the later 'LocoLink for Windows') is a hardware / software combination that connects a PC parallel port to the expansion connector of an Amstrad PCW, and provides the software tools for both transferring LocoScript documents to the PC, as well as converting them to RTF or TXT formats. Note that the later PcW 16 has part of LocoLink built-in, and while this means documents can be transferred from an older PCW to a PcW 16 and then onto a PC, PcW 16 computers are few and far between, making this option unlikely.
PCW LocoScript used CP/M format for its discs, so LocoScript files are likely to be found in a CP/M file system.
Once you are at the stage of having individual document files:
- AILINK by Ansible Information is former commercial software for Windows, now free, which can convert PCW LocoScript 1-4 documents to more modern formats such as RTF, keeping most of the formatting codes and special characters (not Greek and Cyrillic). It can do bulk conversions. If you're not trying to read actual floppy discs with it, it should work fine under modern Windows. It runs adequately on Linux under Wine.
- The PC versions of LocoScript could read PCW files, and had an export function to other formats, but are no longer particularly easy to acquire and run themselves.
