ShaBLAMM! NiTro-VLB
NiTro-VLB was a computer system that used a QED R4600 microprocessor implemented on a VESA Local Bus peripheral card and designed to function when connected to a host computer system using an Intel i486.The NiTro-VLB conformed to the ARC standard, and was produced and marketed by ShaBLAMM!Further, as a "parasitic" or "symbiotic" coprocessor, the NiTro-VLB was designed to co-opt the host 486 processor from running, and used four megabytes of the host 486 motherboard's system memory as a DMA buffer (although the NiTro-VLB required its own separate DRAM main memory, in addition to any memory installed on the host 486 motherboard).This is a type of "parasite"/"host" upgrade card configuration, in which an entire motherboard and processor are implemented on an expansion card designed to connect to a host motherboard's expansion slot.Such configurations are rare among computer systems designed to run Microsoft Windows.
