If you want to talk real poverty, my first 386/486 was in 2001. It was free!
Basically put, I got a Kingspao Model 35 barebones cased 386 SX-25 with an Addonics Monitor and a 101 key keyboard. I had a loose Zeos 486 DX-33 motherboard laying around at home. For the first six months of using that thing, I spent only a grand total of $30 on it - $25 for a brand new EPO 52x CD-ROM, and $5 for a New Old Stock CMOS Battery.
Then we put down about $200 on it that summer - new HP InkJEt 841C printer - the last printer they made with drivers for Windows 3.1. A 56K US Robotics V-90 external Faxmodem, and a $15 Radio Shack mouse. I also bought a $15 DX4 voltage adapted 100MHz CPU for $15.
THAT was the first computer I had internet on. AOL, $21 a month, using AOL 3.0 and AOL 4.0 on Windows 3.1 over MS-DOS 5.00. Then I downloaded MS-DOS 6.00 from a questionable website at the time - it tried to give me viruses....but because nobody used 3.1 anymore they flew over me like a set of Jet Fighters over the bare desert and quickly deleted from the teensy weensy internet cache on my 124MB Maxtor HDD. Oh, and I was doing ALL of my surfing in 16-color 640x480, so everything was dithered, and my serial port - uni-directional. I had to resort to putting a glass of ice cubes w/a barrier over the top of the modem to keep connected any time longer than 20 minutes. Redneck thermal cooling on my modem because of an uncooperative 8250 UART.
And you want to talk availibility and pricing - they were friggin EVERYWHERE. My next PC? Another 486, this time an IBM PC-330 100dx4 6571-W5K from a bank that I was paid with for fixing my ex-room mate's AMD 5x86-133 - which she gave me three months later when she got a Data General Pentium 90. By that point I had a 386 DX-20 that was $3000 in 1988, but again, cost me nothing. People were literally THROWING old hardware at me - "ah yes, Creepingnet likes old computers, I got this old beige doorstop in my closet, I'll let you have it,actually, I'll pay you $5 to take it away".
At the end of 2001, I had FIVE computers. All 386/486 variations. End of 2002, NINE - including several PS/2's, including a 286. End of 2003, I had four macs, six or seven 486's, a few 386's, 2 286's, an XT Clone, a CoCo III, but my "modern" box by that point was actually modern - it was that 386 DX-20 with the omtherboard ripped out and the backplane modified to accomodate a microATX board and had a Pentium III in it.
When the 486's were new, we did'nt have computers. My mom had a Smith Corona electric typewriter that lead to her banning K-Mart for life. The closest thing I had was an Atari 2600, later an NES, and a Game Boy and SNES I bought with my own money. My older sister had a 386, and the other a TAndy 1000 SX that became my first PC in 1997, but were a split family. I think hers was $1500 and ran DOS 5.00. I spent hours on that thing, and she ran it into the ground, until 1997, when the HDD Died. I almost got it, but we could not fit it into my luggage to take it back home from Idaho. It hit a recycling plant years ago or so I'm told......but if it turns up on unlikely chance, I'm running with it!
