I'm trying to remember exactly what my original 386 had. It was a custom built tower by a computer shop. It is likely I'm confusing the number of cards, as well as megabyes with gigabytes - as when I first got it - I vaguely remember 128k increments which were later replaced with 258k increments. (Or was it 258s replaced by 512s ???). Anyway - the math doesn't work out. The box was huge, but not that huge. And I had money back then, but not that much. Your "2mb" number seems far more realistic. I vaguely remember there were addressing issues, not all the memory could be used directly, and it was an odd lot - that is not 2, 4, 8, but something like 3, 5, ... . It also gets confusing since the box was converted to a Venix workstation with additional newer hardware. All I really remember was it had two 80mb Seagate HDs, two floppy drives, a Colorado Tape drive, and that free CD drive MS gave away to Consultants, and literally a rack of cards inside (a graphics card, HD card?, a 'stacker drive' card, a sound card, memory cards, ethernet card, ...) and the base price was $3600 (monitor, tape, sound/speakers, not included <g>). [And also my prized Hayes Smartmodem, which I believe was a hefty chunk of change all by itself. <g>] So yeah, I'll agree with you - I'm probably full of it. -ralph

Increasing memory degraded memory performance. : : Helmut. : And then the BIOS settings needed to get fiddled with. 80ns, 60ns and so one with perhaps 120ns memory chips needed some attention. I think the timing specifications went up to perhaps 180ns or 240ns even, just depending upon how far back you want to gander. I am thinking back to the early- to mid-1990s at this moment when I worked for a computer store and was calling people in China looking to buy memory directly from China (or rather that little island that the British owned(?) -> Hong Kong). Windows 3.x ran on various versions of DOS (some not owned by MS). Sales people pushed a wide variety of memory managers back then, both for "extended" memory and the "expanded" memory managers. I stayed away from anything that dealt with "expanded" memory. I always ended up with too many head aches from trying to get "expanded" memory to work properly. -- Jim Carlock |
