Either IBM announces new RTs for UniForum next Tuesday, or the company’s avowed commitment to Unix is nothing but a smokescreen to hide the fact that its real intention is to do all it can to corral the AT&T Co operating system and confine it to as few niche markets as possible: there are no hot rumours of new RTs flying around, although one UK reseller is looking for the new models very soon and expects the next generation to support a much larger number of users, possibly by use of a multiprocessor RISC architecture; in the US, the best IBM has said is this year and that the machines will match or better the top workstation in the market, which it sees as being the DECstation MIPS Computer Systems Inc RISC-based machine – but in that interview the company indicated that the new models would not arrive until the third quarter, by which time a whole host of workstations, led by a string of fast Sparc-based ones, will have hit the market and left the DECstation – and by implication the new RT as well – spluttering in their dust.
