In the early 1970s a socket to hold multiple DIP chips was being sold under
the brand name DipStik. Up to six chips were inserted in a trough in the
socket, a top screwed on with thumbscrews on the ends. It had solder lugs
on the top and bottom for each of the chip pins.
We are restoring an old electronic device that was built in part with
these, but due to some corrosion we could use replacement DipStik units if
anyone has them.

Does anyone on the list have or have seen the stand that DEC sold with the
VT52? I'm just curious; does the stand screw into holes on the monitor or
does it just sit on top?
>From what I've seen before it just looks like an office chair base with a
top that is the correct size.
Thanks,

the 2.6.0 diag 6.0 bootable and 6.0 patches are probably the most interesting
has there been ANY posts about the Explorer simulator in the last decade?
I've also not verified any of them are what the label says
I ran into a couple that were overwritten. Some I know are correct, because
there were multiple copies.
Hi Ali,
I'm planning on a USB controller, but I've seen ISA projects that are also
microcontroller based so I think it wouldn't be awfully difficult to
replace the USB data pipe with an ISA one.
Zooming out, I have a list of USB controllers to build:
- Kennedy 9800 tape drive
- IBM 6360 8" floppy drive
- IBM <something> 5 1/4" floppy drive
My friends think it's silly, and they're probably right. =P

So, I used SIMH to do an install of a complete OS on
an RA81 disk. I would like to move this to a real disk
and try it on a real PDP-11. Is there a way to do this
using dd on a BSD machine? I tried but it created a
non bootable system. Well, actually, it starts to boot
but then fails very early in the startup process. I used
"dd if=filename of=raw-device bs=1024". Could it be that
the block size needs to be something else?
I know that VTServer and PDPGUI can move disk images but
it would take a week at 9600 baud and I think very little
likelihood of it ever completing successfully.

Hello everyone - since people have already been asking (we even had
someone call the hotel to try to register - that's some refreshing
pro-activeness), we can confirm the date of this year's Vintage
Computer Festival Midwest will be:
September 14-15, 2019
2019 will bring a NEW LOCATION which will be announced in the coming
weeks. So don't call the old hotel - they're already sad that they
lost us*.
Updates will be posted first to our site at http://vcfmw.org, as well
as our mailing list, which you can join there.
Thanks to all who have attended in the past and are considering it
this year. This one will be something special**, for sure.

Anyone who thinks logic starting from common sense has anything to do with
the workings of legal systems is likely in for a rude awakening at some
point.

Fred,
Are we being a little sarcastic or serious? :)Honestly, a sw implementation would be interesting but would it work on vintage hw? Or are you suggesting for use only with a modern system??For example here is my dilemma: my stinkers, whom you have met, are getting old enough to want to mess with my stuff. *shudder* i mean cool! but I really don't want them ruining my one actual original disk for any programs I own. So what I do is make backup copies just like in the old days. And before someone suggests emulators, it is just not the same. I mean if we wanted to emulate everything why bother even preserving hardware?Problem is when we have copy protection, as many games or old SW do, then you need a Copy II PC board. I have one and they are fairly common but ridiculously expensive now a days. So it would be nice if the functions could be duplicated in an easy to use manner. Kyro Flux is powerful but not for everyone. I want an FDC that would cover 90% of the vintage hobby (i.e. Apple II, Mac, and IBM). An FDC that combines a CompatiCard IV with a copy ii pc deluxe and a Match Point card would cover all of the above plus then some.Just a thought.... ;D
