Hiya,
Ahhhh, memories. The first system I worked on was an IBM System 3-15d w/ 512K of transistor RAM running the 1978 RPG 2 and 1979 COBOL compilers and OCL. It had 8" diskette stations, 80 column MFC stations, a chain printer and 2-40meg disk stacks with a tape deck for archive. It would take about 20 minutes to compile say 500 lines of source and run a 2000 record program.
I remember the day the owner came in with the first IBM PC, 2 5-1/4 diskettes, orange monitor. What stuck out in my mind was the big red/orange power switch on the side of the case that was the same one as on the side of the chain printer. We laughed at the little box running PC DOS and "Basic"
I never had any of the early personal computers as I always had midrange and mainframes to work on so my first PC as a Gateway Pentium 60 with 4 Megs of RAM, a 420Meg HD, a 14" color monitor running DOS 5 with Windows For Workgroups 3.11. Cost me $2100 bucks, no CD ROM, no sound card, no modem.
I'm still in the computer field, I specialize in building scalable private clouds. At the house I run a multi hypervisor cloud consisting of Hyper-V 2008/2012 and ESXi 5.1 hosts with a mix of RHEL and Windows guests on FreeNAS storage. Ya, I'm a geek....
