Luxury! My first computer (Sinclair ZX Spectrum) had 48KB RAM total, and IIRC 8KB of BASIC RAM available.
Guess I win this round, unless there are older farts than me - Commodore VIC-20 with 3.5KB RAM which was plenty for me to do really cool things with in BASIC and 6502 machine language)
My first computer was a TRS-80 Model 1 with Level 1 BASIC. 4KB of RAM and 4KB of ROM.
It predated the VIC-20 by just under 3 years. You might have had 3.5KB free for BASIC programs but the VIC-20 had a comparatively spacious 5KB of RAM and 20KB of ROM.
I did start earlier than the VIC-20 (with TRS-80 Model 2 at school) but you definitely take the title :)
