eCesys 486 66 system
The eCesys 486 66 system, setup to run NEXTSTEP for Intel v3.2 in early 1994. It had 16MB of RAM and a 700MB SCSI Quantum ProDrive hooked to a DPT-2021 ISA SCSI board. The system was built around a fast JCIS motherboard with ISA, VLB, and the unique WinGine local bus graphics subsystem which provided one of the fastest framebuffers for the graphically intensive NEXTSTEP operating system.
I purchased NEXTSTEP Developer v3.2 for $299 at academic discount from my university. Retail for that package was $5999 - for the OS and dev system alone!
In 1996, I upgraded the motherboard and processor, first to an AMD 486 DX4 120 and, later, to an AMD 5x86 133 which I ran, overclocked, at 160MHz.
