[Kenwood] TS-950SDX EPROM discontinued

[kk2ed at comcast.net]

Ok guys...

I have 27C512 eproms ics here in my shop.  If someone is willing to send me their original chip, I will gladly read it and make the hex code file available to those in need who have access to a programmer (aka eprom burner).  For those who don't, I will burn a new chip for the cost of the chip and usps charges, which is approx. $10-12 for the blank chip, and $5 for usps priority mail. Those not in a rush can have it sent 1st class mail for around $2 or so.

You missed mine. The eprom is a 27c512 dip. Under the sticker might be a
dash number (i.e. -30) for speed.

The programmed version is the RJDVF Portion. If you have a programmed
version, Eric said he could read it and program another EPROM. He just
needed the type of EPROM.

And you missed my point:

Qty.  	Part Number  	Description  	Alternate Part  	Price
Discont. 	 27C512RJDVF  	 MICROPROCESSOR TS-950SDX
$23.22

Note the "Discontinued".
