Applications for school administration and financial management - SIMS and SCRIPT (a COBOL-based school administration system) - were also offered in a bundle with the R140 workstation. The database application development tool DataFlex was announced for the R140 in mid-1990. Legacy Despite Acorn stating an intention to offer a Unix system from as early as 1982, with the National Semiconductor 32016 platform being the proposed vehicle for such a product, technical difficulties with the 32016's chipset led to the Acorn Cambridge Workstation - the surviving product from the Acorn Business Computer range - shipping with a proprietary Acorn operating system instead of the planned Xenix-based Unix offering. With the development of the ARM chipset, however, Acorn was finally in a position to deliver its own system capable of running Unix, announcing work as early as the autumn of 1987 on an "upmarket ARM-based workstation to run the Unix operating system" for release in mid-1988 to compete with Sun and Apollo models in the higher education market, featuring a built-in WE32206 "arithmetic co-processor", and eventually bringing the R140 to market alongside the second iteration of ARM2-based Archimedes 400-series models and the R225 and R260 to market alongside the high-end, ARM3-based Archimedes 540, all within the space of a couple of years. The introduction of the R225 and R260 renewed the enthusiasm of some commentators who conceded that the earlier ARM2-based R140, alongside competition based on the 80386, 68020 and 68030 processors, were underpowered to run "wedding-cake configurations" of the X Window System, Motif, X.desktop and other software, but considered Acorn's ARM3 products, alongside competition based on the 80486, SPARC and 88000 processors, to be more capable of such tasks. Nevertheless, Acorn discontinued R260 production in 1993, shortly after announcing the floating point accelerator unit, which had been promised for 1991 and repeatedly delayed, and subsequently offered no new RISC iX system products. Although there were expectations that Acorn's corporate parent, Olivetti, might have provided opportunities for ARM-based Unix workstation products, leveraging its relationship with AT&T as the proprietor of Unix, it became apparent that AT&T's own interests lay with products based on the SPARC architecture, with AT&T also having an ownership stake in Sun. Olivetti's own workstation strategy was incoherent at the turn of the 1990s, with the company announcing products based on MIPS and Alpha architectures before settling on Intel's architecture once again. Olivetti itself had previously made a workstation,
