A stepchange came with the [[Longshot Demo]], the first in which he adopted his new pseudonym. This included hardware splitting and combined more effects on screen at once. [[Revolog]] (or Revolution) followed in a similar vein but was a level more accomplished again. At the same time, Longshot participated in the [[Amazing Demo]] with [[Naminu]] and [[P007]] of [[Malibu Crackers]].
[[Naminu]] would soon become one of the members of the new, expanded [[Logon System]]. The "supergroup"'s first release was the stunning [[The Demo]], where Longshot contributed a part two parts but, perhaps more significantly, oversaw the polished, coherent design that was unlike any CPC megademo previously released.
This The [[Euromeeting demo]] would turn out to be his last demo release, but a further innovation was the [[B-ASIC]] utility which enabled Plus programmers to use the new features of their machines from BASIC. Longshot went on to the ST and PC in turn, but has recently participated in French CPC forums such as [http://phenixinformatique.free.fr/ Phenix Informatique] once again. His [http://sergiologon.websystem.9onlinefree.fr/ homepage] contains screenshots from the Logon era, a brief history, and downloads of his personal disc collection.
Though most respected for his coding skills and innovations, Serge's main achievement was perhaps the creation and fostering of the Logon System supergroup, the like of which has not been seen since.
