Looking for weight of vintage computers for Science Fair Project
by Connor S 19 Mar '18

19 Mar '18

Thank you to all who have helped with Connor's science fair project comparing 13 micro-computers! We've been learning so much and greatly appreciate the help testing and interpreting data so far. Connor S. has put together some graphs on time to boot, factorial calculations & time to count to 1,000,000. He also made a comparison table based on information we could find on each computer. We've had difficulty locating the weight of some computers on-line. If anyone can help, we are still looking for the approx. weight of the following computers. (Weight should include computer, disk drives & monitor, if possible) - Commodore PET - TRS-80 model 1 - Atari 800 XL - TRS CoCo 3 - Vic-20 -Tandy model 102 Thank you, Jen & Connor S.

Thank you Tony! The tablet network is about to become much more reliable. In the next week or two we're changing over from the Pi and cheap home router to the new server and a Cisco access point. That should dramatically improve the network. I'm excited about it.

Help Needed for Science Fair with Commodore 64, PET & VIC-20
by C.J. Slade 17 Mar '18

17 Mar '18

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(a)gmail.com <basicprogrammer10(a)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) :)

Museum report

Busy time for me -- warehouse today, Trenton tomorrow, museum docenting Sunday. Still new-ish volunteer Laura and I did warehouse work from about 2pm-7pm today. She put a second coat of paint on the new UNIVAC pallets. I consolidated the huge collection of slide rules into fewer boxes. Then we spent an hour or two playing shelving unit Tetris -- moving things around the warehouse for better efficiency. The result is some things are in more logical places now, and other things that were in the unsorted area were moved into the sorted area. So a net positive. We took another hour cleaning the pile of empty boxes. Threw away some boxes of odd sizes or in poor condition, nested others, and neatly re-stacked all the common banker boxes. We also sorted through a few boxes of miscellaneous stuff and generally straightened up some cluttered areas. It's been an impressive improvement in the warehouse this past year. Jeff B. and Adam deserve most of the credit for it. It is a pleasure now to go in there and see wide aisles with a good amount of open space. We'll need that space for the next huge project (probably post-VCF East) which is to sort, organize, and consolidate our vast collection of books, magazines, and manuals. Trenton will be fun tomorrow but what I'm really looking forward to is the historic and rare minicomputer being delivered here Sunday. What kind is it? Don't you all want to know. :) I will announce it and post pictures when it gets here.

Semi-OT: stereo speakers for museum
by Evan Koblentz 13 Mar '18

13 Mar '18

We're going to need four matching stereo speakers (one for each corner of the exhibit room). I plan to wire together the two at each end of our rectangular space so they're all "front" speakers; this won't be a 5.1 system (but I'll probably put a subwoofer someplace discrete, so it maybe "2.1" so to speak..... I wanted to install speakers in the ceiling. IA management said no. Thus we have to go with conventional speakers. I think the usual black speakers will be ugly against our white walls/ceiling. Does anyone know if decent speakers that are affordable and available in lighter colors? Alternately, if black is this only option then how could we camouflage them?

Trenton is this Saturday
by Evan Koblentz 13 Mar '18

13 Mar '18

We'll have our usual table at the 43rd Trenton Computer Fest this Saturday. Haven't decided what I will bring for a demo machine. (They saw my favorite demo, the Lego system, last year.) Perhaps the Mimeo because it's small-ish and I know a lot about it. I'm not giving a talk this year. But I will attend the dinner banquet.
