The model 1 (aka "TRS-80") was available with 4K. When converting to the
"Level II [Microsoft] BASIC", it was usually upgraded to 16K. BUT,... it
WAS possible, with some difficulty, to get them to do the ROM upgrade
without the RAM expansion.
The naming of "Level II BASIC" often led to confusion, and erroneous
references to the machine as being "model 2"

I don't know whether the model 3 was available with 4K. I think that it

I am confident that the model 2 (8" "business" computer) was never
available with 4K.
