I was born on July 24th, 1938. If I am not the oldest member, then someone else will have to answer - unless I missed your response. By the way, what is the current (unique) list count: cctalk / cctech? Remember that I am a software addict (as opposed to 95% who are hardware addicts) using MACRO-11 under RT-11. My first system in 1960 was the IBM 650 (which has been discussed recently) using SOAP (Symbolic Optimal Assembly Program) as the name of the Assembly Language. The optimal referred to the location of the instructions on the drum which were placed in the next available location on the drum so that the instruction was available ASAP after the previous instruction was finished. The drum size was 2000 words of 10 decimal digits - or about the equivalent of 20 KBytes. I probably used the IBM 1620 in 1961 with assembler. I seem to remember the Univac 1107 in 1963 with FORTRAN. The IBM 7094 arrived in 1965 with FORTRAN and assembler. Then came the CDC 3300 in 1967 with assembler. The next 5 or 8 years are a bit of a haze. The CDC STAR-100 was included during that time period using assembler and MALUS. I seem to remember about 1 MByte of core memory and a program address space of 32 TerraByes (with a 48 bit address). I can't remember the disk drives at all. The PDP-11/05 seemed to arrive around 1975 with MACRO-11 under V02.? of RT-11. The disk drive was a DEC RK05 with 2.5 MBytes per removable media. I think the memory was 32 KBytes of core. Although I occasionally used a VAX after that, I seem to remember running RT-11 on a PDP-11 of some kind ever since 1975. At present I have many Qbus PDP-11 systems available with most not assembled. If I ever get the energy, there are probably enough parts to put together about 2 dozen Qbus PDP-11 systems, mostly PDP-11/23 and PDP-11/73. I still design and write programs, mostly in MACRO-11. But lately, I tend to run RT-11 under an emulator since the emulated features are much better than the real DEC PDP-11/83 that is still available.
