I just looked up my original receipt for my IBM PC, from Computerland,
dated April 2, 1982:
IBM System Unit (48k): $2235.00
16kb Expansion: $90
Graphics board: $300
DOS: $40
RF Modulator: $0
Book: $15
Sub Total: $2680
Tax: $176.88
TOTAL: $2856.88 (such a bargain)
After trying the RF modulator, I bought the Amdek RGB monitor
($769). I later added the solder-in upgrade from Amdek to bump it from
8 to a whopping 16 colors (in text mode only, of course...).
