Whilst sifting through the loft I came across this brochure
https://1drv.ms/b/s!Ag4BJfE5B3onmNYe9v2yiv2abf2Afg?e=0EjFbM
for the Compaq Security Enhancements for Microsoft Windows 2000, which
evolved from the Digital product "Secure NT"
I wonder if any one actually used these products and can talk about them?

I have been working on a project for some time to connect a IBM3270
compatible Alfaskop terminal with its IBM 3274 compatible cluster
controller to the Hercules mainframe emulator.
Yesterday I eventually succeeded. I was able to login to TSO on my Hercules
system that ran MVS 3.8j.
Here are a couple quick video clips:
https://youtu.be/H1Sxt7xjn4Yhttps://youtu.be/CFfB3yCN9OI
To achieve this I created a small piece of hardware I called SyncDongle,
essentially it's just a few level converters, connectors and a STM32F103
blue pill.
On the hardware I run a small piece of firmware, BSCBridge. It bridges
between the sync serial BSC used by the Alfaskop cluster controller and the
BSC variant that the 2703 emulation inside Hercules is using.
More information here: https://github.com/MattisLind/alfaskop_emu
and here http://www.datormuseum.se/peripherals/terminals/alfaskop
There are good chances that the SyncDongle/BSCBridge combo could work with
a 3274 or 3174 controller as well but I haven't tested since I don't have
one. But no guarantees given, though. If someone has a spare 3174-51R,
-61R, -81R or -91R I would be very interested in it.
Actually there is a good chance that it could work with general BSC use.
Maybe for NJE between Hercules and a real IBM machine? Or 2780/3780 RJE
terminals? Or other third party 3270 terminals using BSC.
The BSCBridge firmware only supports non transparent mode at this point, it
works fine with Alfaskop since it does not support anything else. Maybe a
showstopper for 3174 with 3279 terminals? SHouldn't be that difficult to
add transparent mode if needed.

I have a Sunblade 100, got it on ebay for $103.00, landed on my
doorstep. I hacked the nvram chip with a pair of AA batteries, which
should keep the thing going for a hundred years.
I really wanted a STOP key, and found an ad on Ebay for new Type 7 usb
keyboard/mouse, bought the set.
I used a plain jane USB keyboard to install OPENBSD and that works just
fine. The type 7 keyboard works great on a pea sea, and, if the Sun is
booted, running an operating system, it works fine there too.
If the type 7 keyboard is plugged in at any time prior to booting from
media, any time the OpenBoot prom is in charge, the prom reports no
keyboard detected and defaults to a serial console. This happens even
if the type 7 keyboard is plugged in ALONG WITH the generic USB
keyboard I am using successfully with the machine right now.
An advertisement for the type 7 keyboard gave me a clue that this is a
known problem with some early SunBlade machines and that I would need a
Firmware upgrade. I've looked on Oraclle's site for Sunblade 100
firmware upgrades and not found them.
Can someone link me to the latest firmware for the SunBlade 100 so I
can get it to recognize this keyboard?
At present I've got OpenBSD 6.7 running with X and a light window
manager. Got Dillo running as well, so I can surf. Woot woot! I miss
my SParcstation 4/330 though.
Thanks!
Jeff
The OpenBoot Prom utility however, does not see this keyboard at all.

It is apparently true. He had heart troubles, but this was unexpected
and certainly a shock to his family.
I met Curt here, on Classiccmp, about twenty years ago. We are both
hardcore Atari 8-bit computer geeks, but we met in this forum.
He is missed by many as he touched many. Please pray for his soul and
for peace for his wife and children.

Folks,
I first heard this last night (UK time) but from an unconfirmed source so I waited until this morning and woke to find a tweet from AtariAge confirming it. Seems that Curt Vendel of the Atari History Museum amongst others passed away unexpectedly yesterday.
Sending condolences to his family and everyone who knew him. Taken far too soon. RIP Curt.

Subject: Re: Factory Rodent Urine, was Re: Sun SPARCstation LX boot from
CDROM?
To: Chuck Guzis <cclist at sydex.com>
Thanks Chuck,
Unfortunately it is well past cleaning.
The lead/tin alloy has corroded into a hard oxide with very high melting
temperature.
Lead oxide melts at 800+ degrees C and tin oxide at 1300+ degrees C.
This is well past the 300 degrees C a soldering iron produces.
Most importantly the copper pads below and some of the tracks are gone
completely.
About 70% of the board is pristine. Only the section which has been exposed
to the liquid is corroded.
I can't say for sure that it is rodent urine, but when I tried to reflow
the corroded solder joints it faintly smelled like my firewood where rats
nested one winter.
Of course there is no chance for a rat or even the tiniest mouse to get
into a fully assembled Sun/Sony CDROM with the affected PCB side facing
down and somehow urinate upwards towards the PCB.
As the drive was never before disassembled it could only have happened
during manufacturing.
20 years ago when I put the drive and other SPARX LX gear into my display
cabinet I could have easily found a replacement. Now it won't be easy.
The sad thing about it is that everything was pristine when I put it in my
cabinet.
Cheers
Tom Hunter

After having a run of almost half a dozen IDE hard drive failures recently in
a short period of time (on my older desktops which use them, I've decided that
I should see if there's an IDE emulator (using SD cards) available I could
switch to. (I'm not sure why I had so many failures in such a short period; I
can only conclude that they're too old now, and reaching the end of their
service lives.
So soes anyone have one (or more) they can recommend? (IDE simulators only; I
don't want to have to mess around changing anything more than I _absolutely_
have to)? I did find these guys:
http://store.mesanet.com/index.php?route=product/category&path=74_64
in an online search - the CFADPTHD seems like it's close to what I'd want,
except it's Compact Flash; I'd have preferred SD but I guess converting
their interface to IDE is more work.

?I archived the entire website in the summer of 2019, shortly before it went offline in the Fall of 2019. When it became clear that SWTPC.COM was not coming back on line, I chose to host the content at https://deramp.com/swtpc.com/ so hobbyists could still have access to the excellent material Michael pulled together. Mike Evenson also hosts a copy of the website at http://www.swtpcemu.com/mholley/.
Anything you can do to preserve and host the material at swtpc.* is much appreciated!

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

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.

Before I ebay buy a monitor, original IBM 5135, will it match the scan rates of the IBM of the IBM Professional Graphics Controller?
I wanted to keep this system looking all original IBM.
Will I need a different monitor, Princeton or something like that?
Your recommendations appreciated.
Thanks,

Contacts have been made to secure disposition of Bill Dawson and Mike
Holley's site/contents. As part of that effort, I pointed swtpc.org to what
used to be swtpc.com (and also swtpc.org). So if you go to swtpc.org you can
traverse both sites. But that is not why I'm posting..
So in doing this and fixing a few links, I noticed there was a lot of
pictures and info on "first computer store in..." information, apparently
written by Mike Holley and we were just talking about that topic here. Some
may want to go hunting for the computer store that was an adult movie place

Hello all, apparently I've been in this group now for weeks but my
spam filter thinks it's all spam. Fixed that, I hope.
Does anyone have any leads on a MIPS Magnum R4000 or Jazz-compatible
machine? I've been working for a while on trying to round out my
collection of alt-arch WinNT machines, and the Magnum has proven to be
the most elusive.
Thanks
I need advice on a path forward then. From emails I got from Michael, Bill
Dawson gave him authority over both swtpc.com and swtpc.org.
Originally, Bill Dawson had swtpc.com but Michael was managing/uploading
much of the content there under the mholley subdirectory
(www.swtpc.com/mholley). Michael registered swtpc.org and I set that as a
redirect to the subdirectory on swtpc.com. Michael stated that at some point
the sites would be merged and he would be the sole site maintainer.
So now I am hosting swtpc.com and swtpc.org, and ownership of the site is up
in the air. Whoever owns swtpc.com doesn't have an A record, which
effectively kills off swtpc.org (redirect fails) as well. All that good
content (and there's a fair amount) is no longer accessible. I see herb
johnson ripped the site and has a copy over at deramp, but no clue if that
is a complete copy that descended from Bill or Mikes wishes.
My initial plan - since I have no registrar access to swtpc.com and it
doesn't point to my name servers, nothing I can do. But swtpc.org at least
still, is pointing to my nameservers. I will change the apache config from a
redirect to the real contents (but not sure if it should bring up the
content that was swtpc.com or swtpc.org). At least a real site will be up.
That being said, I am moving the sites I host free from one server to
another. That project is ongoing the past few days. I would like to move
swtpc.* as well, but see above.
If someone has a reasonably cogent claim to the content I would hand the
site (both) to them. If it's long been gone and other copies are complete
and commonly used, then I could just delete it but hesitant to do so. I
would like to decommission the old server but this should be resolved first.
Feel free to send me advice/thoughts/claims/rants off-list.

Subject: CYCLOID faceplate for Altair computer...
I seem to remember this being discussed many years ago, but I can't find it.
Anyway, there's an Altair on epay right now with a CYCLOID faceplate.
If I remember correctly, this is just a replacement plastic insert that was
sold simply to "freshen up" an Altair where the original had worn badly,
as so many did. I've done a fair amount of searching but I can't find an
ad or other reference to the product. Does anyone recall the time period?
I would assume it was at least a couple of years after the introduction of
the Altair. 78 or 79? A pointer to an advertisement or one of those "new
product" paragraphs that many of the magazines did back then would be
most helpful.
Thanks,
Bill S.

I decided to get a tvga8900 for mine, as fiddling with 15khz ttl is
just too flaky and problemmatic. Having a real cga/ega monitor would
be cool if I could justify the cost and the space, but a native fix is
an isa vga card so that's my solution. I'm refurbing a 5170 for use as
an imaging tool, ISA tester, etc.
Best,

A wild guess that maybe some on the group may have these files.
I bought the books from abe books, a few dollar's each. They are (vintage 80-90's) but of course the code floppy disks are not there.
Did anybody keep these files?

I hope you say no, because I will probably learn more by keying in the code in the text, and finding my errors.
