Jen, Since I didn't have the live machines easily available, I ran the BASIC factorial program on a emulator called Vice, which is freely available. It is pretty accurate. This link contains screenshots of my results and slight modification of the program for clarity: https://drive.google. com/open?id=1Y1WKpUfp11GPe26577764dXo_8OKsy80 As for the time counting to 10,000 C64 = 9 minutes, 9 seconds PET = 10 minutes, 47 seconds Vic-20 = 5 minutes, 30 seconds (I have no idea why it is faster on an older machine) Let me know if you need this done on the real machine or if emulators are OK. Boot time for all of them is about 1 to 2 seconds. Very fast. Almost immediate. Jeff Brace On Sun, Mar 11, 2018 at 10:48 PM, C.J.

Hi VCF,
Connor S has come the last 2 workshops at VCF with his Dad and loves working on vintage computers. He has been working on the 5th Grade Science Fair project for the past few months. Connor is comparing vintage to modern computers and has been researching and testing the Altair 8800 (clone), Apple II GS, Macintosh SE, iBook G3, Commodore 128 & Mac Book Air. He would like to add the C-64, PET & VIC-20, but doesn't have access to run tests.
Would someone be willing to run the following 3 tests on the *Commodore 64*, *Commodore PET *and *Commodore VIC-20 *this week for Connor to include in his results?
1) Boot Time into OS Time in seconds from turning on the power switch to computer fully loaded in OS
2) Highest factorial calculated (BASIC; Hope I typed his program correctly) Connor's guess it that the PET & VIC-20 will only be able to calculate 33 factorial.
10 INPUT "NUMBER"; A 20 B = A 30 B = B - 1 40 PRINT A "*" B 50 A = A * B 60 PRINT A 70 IF B > 1 GOTO 30 80 END
3) Time (in minutes) to count to 10,000 in BASIC using this program.
10 I = 0 20 PRINT I 30 I = I + 1 40 IF I < 9999 GOTO 20 50 PRINT "DONE"
You can e-mail results to Connor S (& me) at *basicprogrammer10@gmail.com <basicprogrammer10@gmail.com>*. Connor will be happy to acknowledge and thank who ever helps with this additional data on his science fair poster. He would be happy to share final results at an upcoming workshop, if there is interest.
Thank you, Jen (Connor S's Mom) :)
