(1979) The PDP 11/44 (hostname "gigant") is a low-cost successor of the PDP 11/70. The 11/70, brought to the market in 1975, was the first "large" PDP. Large means a 22 bit addres space and a memory limit of 4MB. Do keep in mind that user programs are still limited to 16 bit addressing and hence restricted to a limit of just 2x 64KB, when using separated I&D.
The cost of a new 11/44 has been about half of the listprice of an 11/70. The PDP 11/44 had no Massbus like the /70 has, so it was not possible to use diskdrives with a transferrate too high.
