Saw this archived Northgate Computer ad that had appeared in a May 1991 edition of InfoWorld. The $3,699 "Editor's Choice" PC was powered by an Intel 386 CPU operating at a base clock speed of 25 MHz...and it didn't even come with Microsoft Windows!! The bundled operating system was MS-DOS 4.1. The "Blue Screen of Death" (courtesy of Windows 3.1) was still on the horizon. The SlimLine 386SX-16/20 computers still had a 1.2 MB 5.25" Floppy Drive installed. Northgate made pretty good PCs and arguably the best keyboards outside of the ones that came with the early IBM PCs. Back in May 1991, 4 MB of RAM & a 100 MB hard drive was considered pretty darn good. I'd say personal computer technology has tremendously improved over since that those days and is downright affordable compared to back then.
