Oh, my, sic transit Gloria mundi. I don't think anyone ever called it "Lotus 1-2-3," it was just "Lotus..." nobody knew that or if Lotus had any other product. But let's also take time for a tip of the hat to the utterly forgotten Context MBA.
"Integrated software" was very much in the air then. In fact for many years, and contrary to popular belief at the time, Appleworks outsold Lotus 1-2-3, but was "invisible" because it was sold directly by Apple while the bestseller lists were compiled from sales by distributors like Ingram and Corporate Software.
I believe Context MBA actually preceded Lotus 1-2-3, and was a very, very impressive achievement at the time. In addition to 1-2-3's three functions, it also had a reasonably capable low-end word processor--think WordPad--and a decent communications package/terminal emulator (you could use it to download data to put into the spreadsheet). It had a decent user interface and a high degree of integration--it wasn't just a suite. But it had an interesting Achilles heel: it was written in UCSD Pascal for portability.
"Portability" was sort of trendy at the time, because there was such a zoo of incompatible PC architectures. (The shakeout and dominance of the IBM PC architecture happened with surprising speed). Pascal and C vied for language of choiceCoding for portability had worked wonderfully well for Multiplan, Microsoft's spreadsheet. In a world of dozens of incompatible personal computer architectures, Microsoft could deliver Multiplan quickly on everything. (I remember a friend using it on his Commodore 64). But it imposed a performance penalty, which for some reason wasn't too bad with Multiplan but was with Context MBA, and it ran sluggishly on the IBM PC.
Lotus took the diametrically opposite track, writing in assembly language and often breaking the rules and bypassing OS and BIOS to write directly to the hardware. Lotus 1-2-3 actually became a standard informal test of PC compatibility; it wouldn't run on anything that wasn't a very faithful clone of the PC. Because of its speed, it virtually erased Context MBA from the market and from collective memory.
My personal limited experience with Context MBA was on an HP9800, a 68000-based 1981-vintage $10,000 desktop computer intended for scientific and technical applications, with good HP-IB (IEEE-488) capability. On that platform, Context MBA ran well and was a solid and very likable piece of software.
