Kemet mil-spec cap ???

[Mark (UK)]

Hiya!

I don't know what Stan Bakulas or whatever he's called does all day, but
whenever I ask for an item, it's always "NO STOCK" even though the
website says they've got thousands.

Far too difficult to deal with. I've found America II to be one of the
easiest surplus suppliers to deal with, what with me being in the UK.

Yours, Mark.

Hello!

I'm looking for FIFO buffers in 16k x 9 organization.
The buffers are described as IDT7206-15 (IDT) or CY7C462-15 (Cypress).
The number after the hyphen tells about the access time. The
buffers I
need must have an accesstime in 15ns or less.
Does anybody knows where to retrieve theese (need 8 pcs.) or possible
replacements?

The accesstime is critical since they are working as inputbuffers in a
logic analyzer.

best regards

Anyone have this info?

Yes, you can install it youself. The OPt.5 is a small extra board,
basically a video clamp circuit. There is a small ek special IC on the
board, but when you analyze the circuit you will recognize that a quad
op-amp of gain-BW > 5 MHz will work well.
At least at mine it does so.

Scopes with option 5 have a differnt front panel layout. So, you might
get in trouble to realize this with your non-opt5 scope.
But basically: Yes, it can be field installed.

Go buy one from ebay. They are SO CHEAP now, your time is so much more
valuable.

Hi Mr Phil,

If you've bought the Needham Eprom programmer from Lewin, I think
it's a PB-10 and you can still download the software from the site

http://www.needhams.com/download.html

It runs on DOS and it's best to restart the windows in MSDOS mode
before running the programmer or weird thing would happen when you're
programming the chip.

I 've got one myself and it is still in good use. The new software
can program some of the eeproms too.

You can make your own programmer too. I've seen one programmer yaers
ago in the Practical Electronic Magazine that program the 2716 using
BASIC on a UK101. And there was only a few (1 or 2) TTL chips
connected and you need 3 pieces of 9V battery and a zener diode to
supply the Vpp. Today, just do a google search, You would be able to
get a dozen simple programmers connected either to Apple II or the
parallel port of a PC that will program up to 27256.

Hi there,

tell me web address about these?
thanks...


http://www.crystalfontz.com

I've used their parallel LCDs for a couple of years now.

-->Neil


I use the Noritake Itron VFD Displays in all three of their operting
modes, that are serial, I2C and SPI. I did a lot with those LCD (
grafical and text only ones) but I wasn't proud of their bad viewing
angles and temperature sensitivity. And they all needed to much port pins.

As those VFDs have a 4x4 keyboard matrix controller implemented they
save additional port an memory if used with small controllers. Thats
worth the price.

Have a look at http://www.noritake-itron.com/
In germany the GU180x32D-K610A2 costs about 80 EUR which not much
compared with an adequate fully graphical LCD which needs additional
backlight, backlight inverter and negative supply for contrast, extra
keyboard controller and I2C or SPI converter.

Google "MPSU45" and you'll find plenty of suppliers.

But there is probably a cheaper transistor that will do the job. What are

Dial Elec says the following:

Which I interpret as meaning that it's a NPN Darlington, 2 amp. 40V,

BD677. If size is not a problem, then put something larger in its place
such as a TIP120, which can handle more current and power.

Small Transistor type transformer. Marked Calectro 01-729 on top.
Probably came from an old Lafayette electronics store...boy do I wish
they were still around. Does anyone have information on this little
fella?

Thanks very much!

I believe Action Electronics has a display of those in their store. You
might try asking them. http://www.action-electronics.com/

Also I have an Argonne transformer list from an old catalog, which gives
dimensions and pri/secy DC resistance. That could be used to copmpare
and get a rough idea of impedance. Usually with these small
transformers, the impedance is maybe 5 to 10 times the DC resistance.
But it depends.

It is fake. The "Statement on Spam and VoteNader.org" that is flooding the
newsgroups is apparently not from the Nader campaign; it's from Australia.
It is a copy of a page from Nader's web site, but its real purpose is
apparently to make Nader look bad.

As though Nader needed help doing that; as though any major faction
would vote for a Left-wing Arab.

The horror that is John Kerry and the Democrats (oh how loathsome
Senator Kennedy is prancing!), even with a split vote to Nader, will
probably crush Bush the Lesser in November short of all out war or
gasoline at $0.80/gallon (same thing). Do you thing Bush the Lesser
has the big brass clangers to nuke Mecca, the Ka'aba as hypocenter?

Hi,

if you are using a mcu in your circuit, the RI-R6C-001A from TI will
be the best choice. You have to provide four i/o-lines from the mcu
and that's it. Also, you should implement an antenna-network, which
can be obtained from the application notes in the TI-RFID section.
The RI-R6C comes with a so16 package.

best wishes.
