On June 16th, 1987 the SDF-1 BBS received its first caller at 300 baud. Happy Birthday to the SDF user community!

What was your first modem? Mine was a 300 baud VICMODEM for my Commodore VIC-20 which included a type in terminal program in the user guide.

You had to manually dial the number with the phone, unplug the coil cable from the handset when you heard the carrier, and plug it into the modem!

Page 7 from the VICMODEM manual as follows. The following computer program is for use with the VIC 20. This is a third method of turning your VIC into a terminal. You may type this into the computer and then start it by typing "run", those of you learning to program may find some of the routines interesting! For your convenience, we have provided an explanation of the listing. Terminal Software for the VIC 100 OPEN 5,2,3,CHR$(6) 110 DIM F%(255), T%6(255) 200 FOR J=32 TO 64: T%(J) =J: NEXT 210 T%(13)=13: T%(20)=8: RV=18: CT=0 220 FOR J=65 TO 90: K=J+32: T%(J)=K: NEXT 230 FOR J=91 TO 95: T%(J)=J: NEXT 240 FOR J=193 TO 218: K=J-128: T%(J)=K: NEXT 250 T%(146)=16: T%(133)=16 260 FOR J=0 TO 255 270 K=T%(J) 280 IF K<>0 THEN F%(K)=J: F%(K+128)=J 290 NEXT 300 PRINT " "CHR$(147) 310 GET#5,A$ 320 IF A$="" OR ST <> THEN 360 330 PRINT " "CHR$(157); CHR$(F%(ASC(A$))); 340 IF F%(ASC(A$)) =34 THEN POKE 212,0 350 GOTO 310 360 PRINT CHR$(RV)" "CHR$(157); CHR$(146);: GET A$ 370 IF A$< >" " THEN PRINT#5,CHR$(T%(ASC(A$)): 380 CT=CT+1 390 IF CT=8 THEN CT=0: RV=164-RV 400 IF (PEEK(37151) AND 64)=1 THEN 400 410 GOTO 310 NOTE: Insert a space between the quotes in program lines 300, 330 and 360. Do not put a space in the quotes in line 320. TIP. Once you have typed the above program into your computer, save it on your tape or disk for future reference or use.
