The Nova 1200 executed core memory access instructions (LDA and STA) in 2.55 microseconds (μs). Use of read-only memory saved 0.4 μs. Accumulator instructions (ADD, SUB, COM, NEG, etc.) took 1.55 μs, MUL 2.55 μs, DIV 3.75 μs, ISZ 3.15-4.5 μs.<ref>{{cite book |url=https://github.com/ForgottenMachines/Data-General-Nova/blob/main/Nova%201200%20Technical%20Manual.pdf |title=Technical Manual For the Nova 1200 |volume=I |publisher=Data General |id=015-000002 |date=1971 |page=1{{hyp}}4}}</ref> On the later Eclipse MV/6000, LDA and STA took 0.44 μs, ADD, etc. took 0.33 μs, MUL 2.2 μs, DIV 3.19 μs, ISZ 1.32 μs, FAD 5.17 μs, FMMD 11.66 μs.<ref>{{cite book |url=http://www.bitsavers.org/pdf/dg/mv8000/014-00648_MV8000_PrincOps_Apr80.pdf#page=378 |title=Eclipse MV/6000 Principles of Operation |publisher=Data General |id=014-000648 |date=1980 |at=Appendix F, Instruction Execution Times}}</ref>
