products were not likely to become available for the RISC OS platform, despite the company encouraging Acorn and others to provide them. Once again in its history, Computer Concepts insisted that it was not abandoning the Acorn market, noting the introduction of various product upgrades and peripherals for the Acorn machines, while promoting Xara Studio – "really like an ArtWorks Version 2" – to users of the Risc PC with PC processor card. Since the Computer Concepts name was not suitable for international use, the Xara name had been adopted to market PC-based products. Computer Concepts had been developing its own operating system, Impulse, along with a hardware product (originally named Equinox) consisting of two IBM PC-compatible expansion cards providing Acorn's ARM-based chipset that would "take over processing from the host PC" and run the Impulse operating system, although the company had also stated an intention to make Impulse available for the Archimedes and thereby support its own applications running on Acorn's own hardware. With the introduction of RISC OS and the elimination of many of the concerns about the earlier Arthur operating system, the company announced support in their applications for both Impulse and RISC OS, but ended up only releasing RISC OS versions of applications such as Impression. Another hardware product that was planned but not apparently realised in its original form was a laser printer card for IBM PC-compatible machines, employing Acorn's ARM chipset and Computer Concepts' own PostScript clone. A package containing the PC, printer card, a fax card and scanner was "expected to cost about £4000", and was set to be announced at the Personal Computer Show in September 1988 as "the launchpad for an ambitious office system". Acorn had already delivered a similar direct-drive laser printing solution to Olivetti by the time of the planned announcement, with the intention of incorporating the solution into Olivetti's ETV range. Fax and printer cards both subsequently featured in Computer Concepts' Archimedes-based product line as the FaxPack and LaserDirect, respectively. Having been announced early in the life of the Archimedes, FaxPack was delayed after "serious interrupt latency problems" were experienced with the Archimedes' original operating system, Arthur, which impaired the product's ability to receive faxes. With the original hardware undergoing regulatory approval, and with Acorn unwilling to commit to fixing the problem at that time and suggesting changes to the FaxPack hardware instead, Computer Concepts suspended development and
