another reason to appreciate vintage computers

I forgot how good or bad the Apple Lisa was for kybd-to-input response but it was slower than molasses in the winter for printing :-( This was just rediscovered by boingBoing: Latency: why typing on old computers just feels better https://boingboing.net/2017/12/26/latency-why-typing-on-old-com.html

museum report
by Evan Koblentz 26 Dec '17

26 Dec '17

Jeff B. and I used Tony's van to pick up two new display cases this morning. Same brand/style as the larger UNIVAC display case that we bought last time, except these are each 18x18 (x72 tall) vs. 40x18. Then we spent all afternoon moving some things around in the microcomputer side of the museum. We're not done, but we called it a day around 7pm. When finished we will be able to display certain things that we couldn't safely display before, such as the blue box and 6501 kit. We'll be back at it tomorrow along with Adam. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation

Looking forward to trying it out on my old Tandy 6000HD, and attempting to image the hard drive in my most recent 6000HD.

Museum inventory database software
by Evan Koblentz 26 Dec '17

26 Dec '17

We're looking for recommendations for an inventory database system. Here are the requirements in no particular order. - Resides online so we can view/update it over the internet (awesome if we could view/make changes via smartphone browser, etc.) - Secure + password-protected from prying outsiders (we're not interested in telling the world what we have at this time) - Evan-usable GUI for when we need to customize the fields/hierarchy (we don't want to have to rely on anyone for this) - Not a kludged-together homebrew thing that only the builder can use (we know you can all make a LAMP stack, that alone isn't the solution) - Commercial "cloud" services are fine, but nothing too expensive (f it works and it's reasonably priced, then I don't care if they use Microsoft...) - Nothing hosted on the accounts/servers of individuals/other groups (VCF is a real organization, we need to keep things under control) - We need something relatively soon. This can't be a slow-moving project that gets 75% implemented in six months. - There are open-source museum applications, but they seem way too big/complicated for us. All constructive recommendations are welcome within these requirements. I saw a company called Airtable which might meet the requirements, but I didn't quite understand how to use it. Granted my only hands-on database experience was Appleworks back in the 7th grade. :)

OT: need help upgrading Linux gadget firmware
by Evan Koblentz 25 Dec '17

25 Dec '17

This has nothing to do with vintage computing. I wear a Garmin GPW watch when I'm running. The model is Forerunner 15 with version 2.40 of their firmware. The latest firmware is version 2.70. Officially, they require Windows software Garmin Connect to download the firmware and synchronize it to your device. Garmin Connect in turn requires a late-model version of .NET Framework. I couldn't get .NET Framework to install in WINE, so I started Googling for manual upgrade methods. I found a few relevant posts: https://forums.garmin.com/forum/into-sports/running/forerunner-620-aa/70154… https://forums.garmin.com/forum/into-sports/cycling/edge-520-aa/125491- Both posts indicate a method of downloading the firmware file manually (done), changing it from (filename).rgn to gupdate.gcd, attaching the watch via its USB charging gadget to your computer, putting the file in the right directory, dismounting the device from Linux, and rebooting the device. Easy enough ... except nothing happens when I reboot the watch and its settings menu still shows version 2.40. There are posts about editing out part of the file using a hex editor, for example, post #6 in the first link that I put above. I downloaded a hex editor and can see the data but I have no clue how to use it. The file is on my personal site: http://www.snarc.net/forerunner15_270.rgn Lil' help?

OT: give me your unwanted and unloved printer/scanner, your laser printer yearning to be free
by Jeffrey Jonas 25 Dec '17

25 Dec '17

'tis the season for upgrading your computers. My color printer/scanner is on its last legs. If anyone has a spare, please think of me. Similarly, my laser printer misfeeds despite cleaning the roller and pads. thanks, and see you on Sat at the workshop! -- Jeff Jonas

museum report - Sat. 12/23
by Evan Koblentz 24 Dec '17

24 Dec '17

I went to the museum yesterday. There were three groups of visitors on campus. One group (a family of nine people spanning three generations) spent about 30 minutes in our section, seemed genuinely interested, asked good questions, etc., so that was good. Then I had some downtime, so I made an improvement to the Lego robot. :) The big front gears driving each tread kept spreading off their axles when the robot turned left/right. I installed a guard on each side to stop that problem. Closed and left at 3:30 because I had a family Chanukah party to attend. InfoAge is closed today and also closed next Sunday for new years. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation

pictures: https://imgur.com/a/MbmWO Three days late due to Christmas shipping madness! Assembled one this morning, works fine. I think the blue solder mask effect is decent. Probably put together a run with hard gold plated edge connector on the next paycheck. Thanks, Jonathan
