in LogicBasic:

--- Code: ---Var T Decimal, A Decimal, R Decimal, Xs Decimal, Ys Decimal
Var X0 Decimal, Y0 Decimal, X1 Decimal, Y1 Decimal

Window Res = 150, 250

T = 0.7 'starting point of spiral
A = 0.03 'increment size - spiral trail width
Xs = 125; Ys = 75
X0 = 0; Y0 = 0 'start point of line

While 1 = 1
R = A * T

X1 = R * Cos(T) * 50
Y1 = R * Sin(T) * 50
Straight Ys + Y0, Xs + X0, Ys + Y1, Xs + X1, Black
X0 = X1; Y0 = Y1
T = T + A

Galileo:

--- Code: ---// Ported from ZX81 Sinclair BASIC to Yabasic by Galileo, 10/2018

10 LET A=1.5
20 LET B=0.7
30 FOR T=0 TO 30*PI STEP 0.05
40 LET R=A+B*T
50 LINE TO R*COS(T),R*SIN(T)
60 NEXT T

B+:
I made a little modification of Archimedes Spiral:

Aurel:
Nice one Mark and Galileo too  :)
I just found it on LogicBasic forum..
hmm this LogicBasic seems very nice dialect...
