Once NOSE was running, we began converting the Gamma software. This process took 4-6 man months but lasted about 6 months as, in the process of the conversion, we discovered that the interface between the SCSI disk controller and memory was not able to transfer disk blocks larger than 1024 bytes (the pitfall of being a beta test site). For the most part the conversion of the Gamma software was almost trivial as, by porting NOSE first, the differences between the two systems in initiating disk and message transfers were completely hidden from the Gamma software. In porting the code to the 386, we did.
