Open Source RISC OS Business Software

CRC RevEng is a portable, arbitrary-precision CRC calculator and algorithm finder. It calculates CRCs using any of the 113 preset algorithms, or a user-specified algorithm to any width. It calculates reversed CRCs to give the bit pattern that produces a desired forward CRC. CRC RevEng also reverse-engineers any CRC algorithm from sufficient correctly formatted message-CRC pairs and optional known parameters. It comprises powerful input interpretation options. Compliant with Ross Williams' Rocksoft(tm) model of parametrised CRC algorithms.

Fireworkz combines the features of Wordz (a word processor that you can use to write letters, reports, books, invitations, shopping lists, schedules and other documents) and Resultz (a spreadsheet that you can use to perform calculations, analyse figures, and produce colourful charts) enabling you to do even more; incorporate live results in your reports, or perform an automatic mail-merge to your friends or customers. If you are using Microsoft® Windows®, Linux or macOS, and don't know what RISC OS is, you may be better off using LibreOffice!

PipeDream 4 can be used for word processing: to create letters, reports, invitations, film scripts and books. You can also use PipeDream 4 as a spreadsheet: to create ledgers, simple shopping lists, complex scientific models and cash flow forecasts. You can even use PipeDream 4 as a database for storing parts lists, names and addresses, details of personal collections and mark sheets. PipeDream 4 requires RISC OS 3.1 or later to run. If you only have RISC OS 2.0 or 2.01, PipeDream 3 is the one for you.
