Found In: 3000 - (Usually Rev 05, 06, 07) 3000T - (Usually Rev 05, 06, 07) 4000 - (Usually Rev 09, 11) 4000T - (Usually Rev 11) Boxer (Unconfirmed but likely due to its Z3 slots) (Probably Rev 11) Buster is usually used in reference to the Zorro Controller chip in the 3000 and 4000 series machines. However technically its the zorro controller chip in some 2000's and the Zorro III controller version is called Super Buster. Revisions 05, 06, 07 have no support for Zorro III DMA Revision 09 tries to implement Zorro III DMA but is bugged and generally fails. Upgrading to revision 11 buster is generally a good idea as it fixes many of the DMA problems with Zorro III and is also faster than the earlier versions. Revisions - 05 - 06 - 07 - 09 - 11
