All of the 2001 series had 9"display, earlier ones displaying whitish-blue the rest gool 'ol green phosphor. The original BASIC (Powers up with *** COMMODORE BASIC ***) has neumerous bugs and lacked disk support the upgrade BASIC (### COMMODORE BASIC ###) had many bug fixes and is very close to 64 BASIC in operation and syntax. There are two motherboards associated with the 2001 the 8k static ram motherboard (only in original PETs) which was limited to 8k ram and used MOS RAMs (Which they soon stopped producing, they just weren't good at memory chips) and the later Dynamic RAM boards which were expandible to 32k.
