Me and Wade are pondering ordering a bunch of long strips to keep on hand for our 720 board woes. I hate keeping specific sized sockets on hand. So my question is this:

Is there somewhere I can buy long socket strips at a reasonable price, so I can cut them to size as needed?

Just buy decent dual wipe sockets...

Unless all the pins are perfectly straight on your chips, you're likely to damage the machine pin sockets when you insert the chips -- especially since you're dealing with SIP strips instead of full DIP sockets, and it's likely you won't have soldered the SIPs perfectly perpendicular to the board.
 
Well dang, I guess I have to order specific sockets then. I've used pin strips before, and it works great. It is nice for when you have a single chip that needs a new socket - just grab a strip, cut to size, and install.

I figured surely buying bulk pin strips would be cheaper than buying formed full sockets. I was wrong.
 

For Machine pin sockets - I (GPE) have Jameco beat on all sizes.

But, for SIP sockets -- there is a seller on ebay that is constantly selling 40 pin SIP sockets at a very cheap price - something like 10 for $9 (can't remember exactly how much) ... considerably less than my cost and I buy them by the case.

SIP sockets typically cost considerably -more- per pin than DIP sockets. I assume it is mainly because the DIP sockets are produced in higher volumes.

To keep spacing proper when attaching a SIP socket - use another DIP socket to hold the two SIP strips in place. Plug the DIP socket into the two SIP strips, solder the SIP strips and then pull the DIP socket.

Me - I always use DIP sockets as they are easier to use. But, I normally don't have to worry about whether or not I have a certain size.

There are cheaper sockets out there.
Avoid single beam or single leaf sockets like the plague.
Twin leaf usually work ok. There are good ones... and *cheap* ones. I used to use a lot of MillMax twin leaf sockets - but they don't make this type of socket anylonger.
Excellent advantage to using a machine pin socket is when you have a bad plated thru hole at the socket -- you can solder the socket at both sides of the board. I have had to resort to this many times when fixing other people's "repairs".

GPE...is that Great Plains Electronics?

I have a couple of questions:
Do you carry wire wrap sockets?
Do you carry pluggable wire wrap sockets?
Do you have 6502B (2Mhz)?

Nope, no wire wrap sockets - never had anybody ask for them before. For sockets - I only carry standard machine pin DIP and SIP sockets. I'm considering adding some dual wipe IC sockets - decent but low cost ones.

And, I'm out of 6502's completely. Getting real tough to find them unused.
I have been trying to work with Western Design Center for better pricing on these and to finally remake 65C32's. But, these guys won't budge an inch....

hehe, doesn't matter now. I'm getting rid of this eternal headache. There are sockets galore, and they all need replaced to really know for sure what the problem is. There is a 6502 chip that is a problem, but apparently it is another hard to find chip. The socketed ram chips are a common problem. The CPU chip is apparently obsolete, so you probably couldn't do anything on that front.

Mainly, a kit would consist of a ton of sockets, all of the board connectors, the molex connectors, and pins. The CPU board has this really small pitch connector, and from what I've been told it (and the pins) may not be available. I don't know for sure.
 
I have 36 pin machine pin sips listed on my site for $2. Buy 10+ and I can do $1.20.

Im not sure what size(s) your looking for but I also have dual wipe sips in 12 & 16 pin lengths.

PM me the part number of the cpu chip and rams in question and I will see what I can find. Unless its a custom cpu I can probably find it.

Nothing like replacing bucket loads of flakey IC sockets.

Surprisingly... one version of 6502's are still made. They are 65C02's made by Western Design Center. These have a CMOS (low power) core but have TTL compatible IO pins. There was one function that was different with these -- I cannot remember what it was but for 99.999% of the people, it didn't matter.

They also make 65C21's -- a compatible version of the ever present 6821 with low power CMOS core and TTL compatible IO.

The only problem with WDC parts is they are too expensive.

Ed, I just got a great buy on new 6821's, they are in the states too. I think I have 150 of them coming.
Next thing is to find some 6532, they are getting scarce.

I have to agree here. Dual wipe sockets are inexpensive too so having a bunch on hand is pretty practical.
