However. the new hard drive units were quickly overshadowed by taik of an Amiga version of ATonce, the PC emuiator for the ST. Detaiis were soon confirmed: The Amiga ATonce wiii cost 6200 and piug into the 68000 socket. providing an 8MHz 80286 rattling out a performance of about 6.7 on the weii-respoctcd Norton scale. This wiii probabiy be the fastest emu iator technicailv possibie becausc the poor oid Amiga is stiii held back by the speed of its custom hard ware. Fuii support for Amiga hardware - fioppy drives, hard drives and extra memory - is promised, but the most impressive thing is that MSDOS wiii run quite happiiy in its own iittle window: That's right - mui-titaskingI The tiny circuit board has oniy two chips, the third in the photograph heing the repositioned 68000. One is the actuai 80286 processor, the other the sophisticated ASiC which makes it aiI possibie. For those with weak wiiis, Siiica are taik-ing of providing a fitting service which won't invaiidate warranties. When the Vortex unit hits the streets in "iate October " ther wiii be two PC emuiator hard ware systems avaiiable for the Amiga, for the KCS Power Board has been avaiiabie for some months now. Both boards shouid do weii. for whiie the KCS has ease of fitting. suppiiec DOS and utiiity software and an inté grai RAMexpansion on its side, the ATonce may pip it on price and performance.

Virus aiertI THE worst nightmare of every Amiga owner has corne true: A virus has been distributed on a magazine cover disk. But don'I panic. it's not lmfga Compu fng. rather issue 3, disk 2 of games-based "mag-on-a-disk ' rAMpoge. The virus is of the strain "Lamer H", and given the chance iI wiM destroy as many disks as it can. It is a "boot" virus, in that iI spreads hy copying itseif on to the Brst few tracks of a tloppy. Cnfortunateiy. most commerciaI software uses these tracks for its own pur-poscs. so a rampant virus couid easiiy destroy an expensive software coüec-tion in one session.
