So, it's taken me a while, but here are some more of those D&D variant rules being used in early 1980 in Fayetteville, Arkansas: the first version of the D&D rules I learned.
I shd stress that these are for the most part typed, with the exceptions hand-copied.* Nothing was typeset or xeroxed** from a book or even a magazine.
Group I 01-65
Group II 66-95
Group III 96-00
Eagle-Winged Human 01-30
Bat-Winged Human 31-36
Other were 99-00
Common Troll 01-20
Common Ogre 21-44
Cave Troll 45-56
Hill Troll 57-67
Frost Giant 68-78
Fire Giant 79-84
Hill Giant 85-90
Storm Giant 91-96
Mountain Ogre 97-00
Ogre Mage 01-25
Mountain Troll 26-45
Cave Giant 46-70
Stone Giant 71-99
Hellmarch Troll* 00
*2% chance of being a troll mage

--also on this page, probably just because it fit, are the rules for changing ability scores, lowering one score in order to raise another:
Str to Agil 2:1 not reversible
Str to IQ 2:1 reverible
Str to Wis 3:1 "
IQ to Wis 2:1 "
Wis to Dex 2:1 not reversible***
Next up comes the Characteristic Table, listing all the pluses and minuses you get based on what race your character turned out to be, with the ability scores listed along the top and the character race along the left margin. The ten characteristics given are Str, IQ, Wis, Dr, Dex, Ag, Voi, Com, Sz, & Con.
For example, a Hobbit (so named) gets no change to Str, IQ, or Wis; +6 Dr, +4 Dex and Ag, no change to Voi and Com, -12 to Sz, and +6 to Con.
By contrast, a Stone Giant got +10 Str, -33 IQ, no change to Wis, Dr, Dex, or Ag, -5 to both Voi and Com, +55 to Sz, and +10 Con.
Also on this page are possible bonuses and penalties for rolling really well or really poorly on characteristics. If you rolled 18, you could roll again. A 16 on this second roll gave you +1 to the characteristic [=19, I suppose]. A 17 gave you +2, and an 18 a +3 and the right to roll again (and so forth). Similarly, if you'd rolled a 3 when generating the character you had to roll again. A 5 on this second roll gave you a -1 to that characteristic [=2, I suppose]. A 4 gave you a -2, and a 3 a -3 and you had to roll again. I'm not sure how a characteristic score of 0 or below worked; hopefully not many had to face that dilemma.
Also on this page is a note that female characters all get -3 to size, and two more minor random tables
L 01-30 N 31-70 G 71-00
G 01-30 N 31-70 E 71-00
As you can see, this game really believed in random dice rolls.
More to come.
(*by me -- my handwriting was more legible in those days)
(**because we didn't 'photocopy' back then)
(***this tends to confirm my memory that you didn't get to arrange the scores: you had to take them in the order rolled. So if you wanted to play a magic-user and rolled a high strength and low intelligence, you were just out of luck)
