Re: Q: Plotter bed repair with MonoKote?

I find that it is too much pre-stretched I carefully remove some of the stretch with a heat gun and a frame to hold it. You'd need to experiment some. It has to have a little stretch left to shrink. Dwight From: cctech on behalf of David Collins via cctech

For anyone that isn’t familiar with the XP1000, it’s seriously worth rescuing. It’s a Compaq system with an Alpha 21264 CPU in it. Basically it is something like a DEC PWS 433au/500au/600au. Good for both OpenVMS and Tru64. I know they made at least a 500Mhz and 667Mhz version (I have
