Here's a one-line program that will tell you how much RAM is installed in your Model 100/Tandy 102 computer, regardless of how many files or what programs are currently in RAM. (Spaces have been added to the one-liner to make it easier to read, but are ignored by the computer when you type it in.)

(Just curious to know if there is a trick way show how many memory modules are already installed on the M100). Fm: Mike Nugent (TMN East) 71426,1201 To: william edmisten 72737,3703 (X) Okay, we'll can let the computer tell you how much RAM is already installed. The Model 100/102 stores this info in memory locations 64192 and 64193. Just go into BASIC, type the following line and press : PRINT 64 - (PEEK (64192) + 256 * PEEK (64193) / 1024)"K" That command takes the info from those memory locations, converts it to "human talk" and prints it on the screen for you. -- Nuge --
