Here is a list of 1980's / early 1990's computers I own (listed by year):
1980: Apple II plus, TRS-80 Model III
1981: Vic 20, TI-99/4A (2 - 1 NEW in box!)
1982: Atari 1200XL, Commodore 64
1983: Kaypro II, Atari 800XL (2)
1984: Apple IIc, IBM Portable PC 5155
1985: Amiga 1000, Kaypro "New 2", Commodore 128
1986: Colour Computer III
1987: Amiga 500 (2), Mac SE, Compaq Portable III
1988: Amiga 2000HD
1990: Amiga 3000, NeXTstation
1991: Mac Classic II
1992: Amiga 4000
1993: SGI Indy
Notice how only 2 are actual "PCs". I generally hate PCs, but these two were free and they are from the 80's. The IBM has a nice "clicky" keyboard & amber screen and the Compaq has a plasma screen.
I now use a couple "modern" computers (which I got free) running BeOS, but the keyboards I use with them were made in the 1980's - nice "clicky" 1984 IBM AT (best keyboard ever) and 1986 Model M.
Besides the clicky IBM keyboards, the "award for best keyboard feel" goes to (surprisingly) the TRS-80 Model III, TI-99/4A and the Kaypro "New 2".
