Bitsavers down?
What happened to www.bitsavers.org? It has been down for at least the past 24 hours. I can still ping the website, but http requests time out. The bitsaver domain name here in Australia resolves to 208.77.18.144. Thanks Tom Hunter

Re: Bitsavers down?
Hmmm - I just tried a VPN into the US and the bitsavers website is up and running. The IP address is the same, so it is not a DNS issue. Al, is Bitsavers blocking some HTTP access from Australia?

Re: michael Holley?
Sorry, I did not see your post that there was no concern of losing Michael’s SWTPC content. I simply did not want to see more great material disappear from the internet as our peers age and become unable to maintain their web presence. I’ve seen that happen over and over now. I’ll remove my mirror of Michael’s SWTPC content. You can contact Michael Evenson and let him know his assistance in preserving the content for the benefit of the hobby community is also “unauthorized.” I presently pay for 150Gb of bandwidth on deramp.com to host material for vintage computing hobbyists. I’m surprised the swtpc.org bandwidth requirements are high enough to be an issue that requires your “grace” to allow us to view its content. Mike

I tried the IP address from nslookup (same as Tom) and got no result either. Tracert reports through to nocarrier.net (same IP as bitsavers) though. Steve.
Re: Bitsavers down?
It is all good now. Last night I tried to look for some PDP-11 documents and it didn't work. As it didn't work today I thought I better report the problem. Thank you Jason for unblocking us down under. :-) Best regards Tom Hunter On Sun, Aug 30, 2020 at 4:27 PM Steve Malikoff via cctalk < cctalk@classiccmp.org> wrote: > Tom reckoned > > Hmmm - I just tried a VPN into the US and the bitsavers website is up and > > running.

Re: michael Holley?
I cannot see where the problem is. Thank you Mike Douglas for taking the initiative and mirroring the website! I appreciate it and everything else you are doing. Mike Douglas and Mike Evenson please keep the mirrored content up and running. If J's "grace of bandwidth" is reduced by having an alternate source for the material accumulated by Michael Holley so what harm is done to anyone? J there is more bandwidth for your other stuff. Be happy. Don't start fights among friends. Lets stick together. There is enough nonsense happening in this world already. The "swtpc.com" domain registration is still active but it doesn't point to any IP address. The registration expires on 2021-10-31. So J if that is your domain please update the domain registration so that it points to the material. Peace. Thank you all!

Re: Sun SPARCstation LX boot from CDROM?
I removed the PCB off the CDROM drive and on closer inspection noticed a region of substantial corrosion of solder joints on the component side. About 70% of the PCB had solder joints that were nice and shiny like brand new. The remaining section near the front of the drive was quite badly corroded and it also looked like there was some liquid spilled over that section of the PCB (component side). When I tried to re-solder a few of the worst affected components they just fell off and the copper track below them was gone. When heating the solder joint the solder wouldn't melt it was just pure led & tin oxide. Interestingly as I heated the solder joint there was a faint smell like rat urine. I now wonder if 25+ years ago during production of the CDROM at the Sony factory some rodent relieved itself over one or more PCBs and next morning the PCB got assembled into a CDROM drive. It worked for a few years before I put it away in my display cabinet. Slowly over the next 20 years the uric acid corroded solder and tracks. This could not have happened after the assembly because of the small opening in the unit where the caddy is inserted and also because the component side is facing down. Anyway this is the sad end of my Sun CDROM drive. :-( Tom Hunter On Sun, Aug 30, 2020 at 1:23 PM Tom Hunter wrote: > I have now installed an old Adaptec AHA-2940 Ultra SCSI card with > micro-SCSI interface in a Windows XP PC.

These numbers are usually normalized to a JEDEC workload. From that you can often extrapolate to your workload if you know it well enough... It is one of the things I evaluate for Netflix's CDN SD and CF cards almost never do unless they claim industrial use. Ditto USB sticks, but with more industrial models available. Warner >

The warranty duration is a good starting point. If it's the absolute legal minimum (i.e. two years in the EU) then that tells you all you need to know.
Re: Looking for an IDE simulator
Technology wise, there is an inherent limitation on the number or writes with the SSD design. While it is not as simple to calculate as a mechanical system, it does have a limitation. I don't know the exact number with the current technology, earlier products had write life times in the tens and hundred of millions of writes. bb On Sun, Aug 30, 2020 at 1:38 PM Peter Corlett via cctalk wrote: > > On Sun, Aug 30, 2020 at 11:02:50AM -0500, Jules Richardson via cctalk wrote: > [...] > > I found it next to impossible to find information on what - if any - > > technology a particular SSD uses to extend lifespan; while manufacturers all > > compete on things like capacity and speed, very few of them seem interested > > in telling us how long their product might last. > > The warranty duration is a good starting point.
