If anyone have the following machines, can you run this BASIC program and show   
   the result from SUM 0 to SUM 7?   
      
   Tandy 1000 (Original 01.00.00 user only), 1000EX, 1000TX, 1000HX, 1000TL ,   
   1000TL/2   
      
   This is BIOS checksum program   
      
   10 CLS   
   20 DEF SEG=&HF000   
   30 FOR B=0 TO 7   
   40 GOSUB 60   
   50 NEXT:END   
   60 A=0:FOR I=&H2000*B TO &H2000*(B+1)-1   
   70 A=A+PEEK(I):NEXT   
   80 PRINT"SUM";B+1?B;"=";A   
   90 RETURN   
      
   According to Tandy 1000HX, the result is following as.   
      
   SUM 0 = 729800   
   SUM 1 = 734842   
   SUM 2 = 881996   
   SUM 3 = 702017   
   SUM 4 = 862721   
   SUM 5 = 531629   
   SUM 6 = 902557   
   SUM 7 = 941086   
      
   I don't know if this value is correct.   
      
   Tandy 1000 BIOS doesn't have checksum byte.   
   So it can't be verified BIOS checksum is correct or not.   
   But this program is helpful to check the BIOS sum.
