Clarence,
The Evergreen Upgrade processor, http://www.evertech.com plugs into
the upgrade socket next to the original 486 sx-25 on my PS/1.
I had it in the Tandy at one time,and there it just goes into
the socket in place of the original.
On the box, they have:
Uses 133 MHz 5x86 processor with internal clock tripling/
quadrupling, 16K of level one cache, and on-chip floating
point math unit.
Replaces 486SX,DX,SX2,DX2 or DX4/75 processor or plugs
into the OverDrive socket.
Supports both 168/169 pin 486 sockets and 237/238 pin
OverDrive sockets.
Also it has:
Triples or quadruples existing clock speed.
Installs in minutes (it does).
They give you a nice installation guide, not needed, just
plug it in and go.

I have two other computers that would need this processor.
I think it gives more performance increase for the $ than
RAM as long as one has at least 8 mb<g>.
It's about $60.00 after rebate and just plugs in as is and
works perfectly.

Also in the box you get a disk that allows you to perform
performance benchmark tests before and after, it's really very nice,
works on any computer and a useful addition to one's toolbox<g>.
On my Tandy, I had 24,276 on the 486DX-50, prior to upgrade
and 34,424 on the Evergreen after upgrade.
By comparison, my Pentium 75 shows 58,806. The PS/1 with
the Evergreen installed is 27,571 running in an overdrive
socket. My Compudyne with an AMD DX4-100 gets 44,019.
My PS/1 using the Evergreen runs at about 100 Mhz according
to the disk's report.
I checked with Micro Warehouse 1-800-397-8508 and they have
it, part # EX6744. They have an online rebate coupon for $40.00
so the net price, without shipping added is $60.00.
Evertech.com also has a list of retail stores on their website,
and I notice that Office Depot in my town has this processor
for sale. I've seen it there, along side the ones to upgrade
Pentium 75's to 233mhz, etc.
The part number on the box is:
Evergreen Part# 131.
