I see, I think you mean the EGC (Enhanced Graphic Color board). I never had an EGC board but I have the user guide of it. The board adds three bit planes to the one of the Indigeneous Card (IND), so it provides 16 color capability to the higher screen resolutions and it adds the flexibility of a color/shades of grey Look-Up Table (LUT) The video bit planes are laid out as folows: A0000h-A7FFFh Bit plane 0 (EGC) A8000h-AFFFFh Bit plane 1 (EGC) B0000h-B7FFFh Bit plane 2 (EGC) B8000h-BFFFFh Bit plane 3 (IND) The MDA card has the following memory layout: 4k of RAM at address 0B0000h for its display buffer. This address is not completely decoded; the entire 32k from 0B0000h to 0B7FFFh is filled with repeats of this 4k area. I/O addresses 03B0h-03BFh. As you see the memory of Bit Plane 1 overlays that of the MDA card completely. So I think it will cause serious problems. Are you familiar with the card? Do you have one? Greetings, Hendrik

the 'x' denotes subsets, such as 3002P, etc.

Question about DEC PMI Processors & Gear Acquisition

On the PDP-11 processors and RAM (and > QBUS to UNIBUS adapter -- KTJ11, I think it is called -- in the 84 and > 94) the PMI is all on only the CD slots of the board. Correct, PMI memory on PDP-11 machines is just communicating on the CD slots. No ribbon cables. However, I'd like to point out that the 11/83 also can use PMI memory. The thing to understand is that for the memory to be connected on the PMI, it needs to set *before* the CPU on the Qbus, and be PMI capable. The same memory placed *after* the CPU means it acts as normal Qbus memory. Some difference in performance. When sitting in the 11/84, the memory sits after the CPU, but all the first four slots are PMI slots in that box, always. Actually, PMI is also not only on the CD slots. A few signals in the AB slots are working differently than in a Qbus as well. And to point out one last, obvious thing, the PMI on the VAX is a bus, even through it's on a ribbon cable. Why would that make it not a bus? Johnny

Tektronix TC-2000 on eBay

by rampaginggreenhulk＠yahoo.com

it's either dead broke or suffering from oxidation/microbial issues. Not worth 120$ to me, but if you're interested perhaps you can talk them down (considerably). Mine was delivered working, but after I pulled it out of storage it exhibited the same behavior as that. Fairly rare, but they turn up.

Where's Jim Leonard? There's a GEM driver in three incarnations (ATTDEBP6.SYS for GEM 2.1 SDDEB7.SYS for GEM 2.2 SDDEB8.EGA for GEM 3.0) that supports the Display Enhancement Board. The FreeGEM driver source at <http://www.seasip.info/Gem/drivers3.html> includes the latest source for this driver; it's in the files whose names begin DEB. -- John Elliott

Setting up a DMC11 on TOPS-10

by robert.jarratt＠ntlworld.com

Some work is being done to get a DMC11 emulation into the SIMH PDP10 emulator. I would like to get DECnet running on TOPS-10 over the DMC11, but I have absolutely no idea where to begin, I only ever used TOPS-20 and never with DECnet and never did any admin things on it anyway. Can anyone offer any pointers on how to get started? Before anyone asks, I understand that TOPS-10 uses the DMR11, but this is so similar to the DMC11 that it may not notice the difference or I can fix the emulation for the minor differences. Thanks Rob

If you think "extreme programming" is horse shit, then you don't understand what "extreme programming" is all about. Go read Kent Beck's book.
