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

by ian.finder＠gmail.com

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) and a 50 pin connector marked P4. The other is a single slot 9UVME board with (8) 30 pin SIMM slots with 1mb SIMM in them, a couple of Weitek chips, another 50 pin connector labeled P4, jumpered with a baby backplane to the other board, and 6 led on the front. Anyone know what these are and where to get drivers? They appear to be Sun 3 era, and the boards are labeled ?Sun OHC? with a megatek sticker. They do not appear to work out-of-box in my 3/260 as console devices- the Kernel does not identify them correctly. Thanks.

What's the secret to LK201 leaf springs?

by athornton＠gmail.com

I got an LK201 recently that was a little damaged in transit. A couple of the keycap assemblies and their corresponding leaf springs have come off. I can see how the leaf springs fit on the little posts on the keycap assemblies, and I can see where those snap into the board, but what I don?t see is how to get that put together and then keep it together while I turn it over and then get it in place. Clearly there is some simple trick I am missing. What is it? Adam

What's the secret to LK201 leaf springs?

by marvin＠west.net

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 ran across it on a YouTube ad (first time EVER I bought something from an unknown YouTube ad!) This apparently is the same type of UV curable "glue" used by Dentists. It cures in about 4 seconds! > My guess is that the formed over part has broken off (you might find > some little white disks of plastic, about 1/8" diameter, rattling > about inside the case).

ISO: DEC VR100 and early X releases

by derschjo＠gmail.com

Hi all -- I was fortunate enough to be able to complete my VAXstation 100 setup this week, after a years-long search for parts. (In particular the M7452 fiber optic interface and the fiber optic cabling itself.) After futzing with the 4.3bsd kernel and compiling X10R4 on my VAX-11/750, I actually have it running! (See the below for a picture) https://1drv.ms/u/s!Aqb36sqnCIfMo_cUO4EiMWOHZVk8yg I'm kind of amazed that it all just worked after all this time. As you can see, I'm using an LCD for the display, and that just won't do. The official monitor for the VS100 was the VR100; a 19" monochrome CRT with BNC inputs on the rear for H and V sync and the video signal (ttl level signaling). Anyone have one of these? I'm also looking for earlier releases of X to run on this -- the VS100 was the development platform for X (and W ran on it at one point as well). I haven't been able to track down anything prior to X10R3. Does anyone know of an archive of these earlier releases? While I'm at it -- anyone know precisely what I need to use this under VMS? I believe 4.7 was the last VMS release that supported it, but there were additional packages that needed to be installed to support it, and I'm not entirely sure what they are. Thanks as always, Josh
