Does anyone on the list know a source for the kits to change SIMMs to
SIPPs. I believe you soldered the tips on. Or better yet a source for these
hard to get 30 pin RAM chips.

I've seen SIP modules made out of SIMMS with bits of wire soldered to the
tinned pads. Of course, it really wasn't a pretty modification. I've never
seen the pins available anywhere, but a company like Mouser Electronics or
Digikey might stock something suitable.
If you are handy with desoldering, you could always retrofit a board with
SIMM sockets instead of SIP sockets. There might be SIMM sockets available
with pins that would fit into the SIP socket too.

You'll have to find out how to get some, but check out product # 3620 at
mill-max.com.
Die-Tech (die-tech.org) makes leadframes, including for SIPs, and might give
you a substantial sample. Their products 5000-5006 look exactly right.
These are from a discussion on Usenet a few months ago that I happened to
remember.

SIMM sockets that would fit into the SIP ones, if they were low-profile
enough, would be the best solution. This is for older GRID LTs and they
are flush with the motherboard inserts, so desoldering sockets isn't an
option. I did find one site that had an adaptor to convert SIP ram to SIMM
but not the obverse. I'll take a look at the sources you mention.

Somewhere in my piles of stuff, I have about 10 never soldered
SIMM sockets, cut into individual units for just that purpose.
The pin spacing matches SIPP sockets. If you can't find another
source, let me know and I'll go digging.
