DO NOT USE DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time it is unfortunately not possible to white list users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

They were in the early 90s as they were sold for 486 CPUs amongst others. (PGA extraction tool)
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

I bought mine on Ebay a few years ago, but I think you might find some on Amibay.

We have a PGA extraction tool. A new '030, a ps/2 mouse adapter and an Aries 169 pin ZIF socket. And a free gift from the exxos store :)

I'm hoping I can dismantle the 169 pin ZIF socket and create the correct pin layout, then I will never break another 68030. I'll attempt that later today.

The socket which was given to me didn't need any modifications.. I use one to test 030 CPUs in a DFB1X :)

Lift the upper layer up, carefully to not snap the tangs. It popped up a little and I was able to recover the tangs one at a time.

I tipped it over and all the pins fell out. Then I reinserted them hopefully in the correct pattern, remembering its a mirror image if you're looking at a real CPU

Put the lid back on and carefully put the tangs in. And we have an '030 specific ZIF socket. :lol: Now back to work!!!
