Does the doorstop iMac at InfoAge provide a true value of these things?

New board member: Erik Klein
by Evan Koblentz 14 Dec '15

14 Dec '15

Folks, Earlier tonight we announced that Erik Klein's VC Forum is becoming part of the VC Federation. With that deal, the Federation board -- myself, Jeff Brace, and Corey Cohen -- voted to add Erik himself to our table. Although the non-profit Federation will own the forum, Erik will continue managing it. Erik will also be our west coast representative, especially re: an event that we haven't yet formally announced, but which is partially cited on the Federation web site. ;) (We really can't talk about that until things are settled with the venue and various partners. Trust me, we'll shout it from the virtual rooftops when it is official!) Erik joined this email list a couple of days ago. Please join me in welcoming him!

Getting Data off old Atari Floppies
by John Heritage 14 Dec '15

14 Dec '15

Dear Hobbyists, I went to VCF East 2014 and I remember a really good presentation on the best practices for getting data off of old floppies.. things like assuming your first read may be your only successful read, etc.. Can someone point me to a web link or send me the tips for restoring data off of old floppies? I have a # of old floppies including (I believe) snapshots of an Atari 8bit BBS I used to run with my father. Some floppies are in OK condition, others not.. and I need to know the order of operations for preventing damage to 'future floppies', etc.. Should I be cleaning the drive after every single disk? what's the best way to clean the drive?, etc... I plan to use a USB or RS232 to SIO type adapter and probably the Atarimax APE software (windows or DOS, tbd) as the 'destination', Thanks much :) P.S. Bonus points if someone can tell me if a 1050 is suitable for doing all of this work.. My old floppies are a mixture of 810 format (single density) and 1050 (dual density). I also think some 810 disks were written in happy drive format, but I believe a 1050 will still read them, just not as fast as a happy 810 drive would.. John H

Classic Tandy compters, New York and The Big Bang Theroy
by Kelly Leavitt 13 Dec '15

I know many of you don't watch sitcoms, but I'm a fan. For those of you that don't partake, you can stop here... So, here's a link between this nonsensical show and our hobby. Specifically, one of the characters (Howard Wolowitz) is named after an early developer for TRS-80 computers. I started working on databases on TRS-80 model II computers. The database we used was called Profile. It was created for Radio Shack by the Small Computer Company in Hawthorne, New York. The Small Computer Company was founded by Howard Wolowitz in 1979. Bill Prady, now a producer for The Big Bang Theory, used to be one of Howard's partners. So, it ain't much, but to me it was fun when I figured this out.

On mobile browsers, when you press the "menu" button, the sub-menus are now indented so you can see the hierarchy. Thanks yet again to Steven T.'s web designer Darren for this improvement.

> they go from $20-$30 to as much as over $100 plus shipping. The "plus shipping" is significant in cost and risk. That depresses the sale price. Consider packing and shipping a forty-pound CRT terminal in a plastic case. Of course you want the case to remain intact and not cracked. You also don't want the CRT shadow mask or yoke to "shift" from impact and misalign the color display (look it up). And consider these are close to two decades old: time and high-voltage ozone have degraded the plastics; so has exposure to light and chemicals with chlorine (bleaches, floor cleaners). Few know how to pack items in these circumstances; and "return for refund" makes no sense because you won't get either your original OR return shipping back.

Teletype Sounds Video Posted (with PDP 11/05)
by william degnan 11 Dec '15

11 Dec '15

Here is a video that has a lot of teletype keyboard that can be used for sound capture in hi-res so hopefully this will do. Except for the non-percussive keys like SHIFT, I noticed no sound difference between keys including LF vs CR. https://www.youtube.com/watch?v=uepU_gTkMFY This is the PDP 11/05 S I was working on last month, with ASR 33 Teletype as printer/keyboard. Entering, editing and running a simple DEC BASIC counter program. -- Bill
