One thing I've tried and seems to work quite well (on another application) is UV curable plastic. The last thing I fixed was when the post holding one side of the exit paper tray broke off, and I used the UV curable plastic to fix it (still working just fine.) The trade name is Bondic, and I

Seeking "MEGATEK" Sun 3/4 era (?) VME Graphics accelerator information and driver

2020-09-13 Thread Ian Finder via cctalk
I picked up a pair (1 set) of these very neat old graphics boards. Alas I have no idea what they are or if there is hope of using them. One is a dual slot 9U VME board that has gobs of video ram all over it, including a board labeled Z buffer. The only output are (3) BNC connectors (R,G, and B) a

> Alas I have no idea what they are or if there is hope of using them. Megatek built graphics terminals and I think plotters that were used in CAD shops. Prime used them with some of their CAD offerings. Megatek also did boards for at least DG, -11, Modcomp systems, maybe others. In fact, some

Hi I've had a VAX 4000/300 sitting around for the past couple of years. The second time I tried to switch it on there was a bit pop from the power supply. The 12v module of the H7874 PSU is completely dead and despite my best efforts I have not been able to fix it. Tonight I decided to remove tha
