MDA 1802 board (was Re: Any stories of Dayton?)

I think STDBus is 50 pin. This board has a 44 pin connector. This is similar to what was used on the COSMAC stuff. Maybe it is compatable with that?? ( also used on the KIM/SIM stuff ). Of course, it may just be some propietary bus. Dwight

The main reason I scan at 600 dpi and not save space by dropping to 300 dpi is that the current crop of OCR software seems (in my limited experience) to produce better results with 600 dpi. (I cannot go higher than 600 anyway, but I probably would not bother with 1200dpi because the OCR stuff I have won't even accept it). I'd rather scan the manuals once and wait 10 years for OCR to get to the stage that it can handle the docs with maybe one error per 100/pages (rather than the current standard of multiple errors per page ...). I don't really want to be going back and doing it again! The long term goal is definitely OCR. Although by the time it's good enough we may well all have OC48 feeds to the home and C3D recordable 125GB drives so there may be no need :-) >I did notice that many of the moremanuals pages tend to >show a scanning line when the're first displayed, as if true >white is noisy in some way --it either is light grey or contains >significant dot content. Is that when a page is first displayed (i.e. for each change of page) or just the first page? I assume that you download and then view locally (I have issues with both NS & IE when trying to use then to view local PDFs via HTML ... I assume it would be even worse with a download thrown in for good measure!) >BTW thanks for doing all the work! No problem.

They get strange changes of font on pages 2 & 3 - I wonder if the original has that or whether it's just an artifact of the OCR. A mixture of text and background image (which is also text). I wonder if they might be interested in converting the multiple hundreds of manuals that live on the current crop of DEC document web sites ... Antonio

The stuff I've scanned (like m3100ma1.pdf mentioned above) is usually US Letter size and done at 600 dpi bi-tonal (1 bit per pixel). The scanner happens to LZW encode the TIFF file. There is no option to G4 encode. That usually turns out to be 200-400KB/page but it so happens that one page in that manual did not look too good. So I redid that one page as greyscale (8 bits per pixel) and that just so happens to be over 50% of the total file size (i.e. wipe that one page and you are looking at more like 400KB/page). It's only 14 pages or so, hence one greyscale page makes a big difference. I've seen someone else quote figures of 50-70KB/page for G4 encoded 300 dpi scans of TOPS manuals, which I assume are the typical US Letter size. Obviously going to 600dpi might be expected to produce a factor of 4 increase (i.e. 200-300KB). Or it might not - who can say with compression! I don't see a SC41MS.pdf on that page so I have no idea of the scanning resolution or the encoding. >Can one re-convert PDP^HF files? I've found that using Acrobat 5 in the office I can covert PDF to individual G4 TIFFs (although this is *slow* but it is unattended) and I can then re-import these (in groups of 50 max) which is reasonably quick. But it sucks away time. So if anyone else needs them cut down, be my guest :-) For the few that I've had to process manually (i.e. book format, with pages individually scanned as all-odd-ones, all-even-ones) the conversion to G4 TIFF is a part of the process I use to stitch everything back together in reasonable time. In that case I'm seeing a reduction of maybe 25% in size (although I've not tried to measure it on a reasonable sample ... so don't quote me). If the scanner gets an upgrade that allows it to do G4 TIFF, I'll certainly use it. If a tool turns up that can do unattended conversion of TIFF-in-PDF -> G4 TIFF (or better yet, G4-TIFF-in-PDF) I'll certainly use it. Antonio

Any stories of Dayton?

by dwightk.elvey＠amd.com

Hi Dan I'm not sure but it looks like it may be a "Standard Bus" type board. I don't recall the pin combinations but it looks like the same form factor. There are a lot of different Standard Bus manufactures and you should be able to get cards and back planes easily. Count the pins and look the spec up on the web and see if it looks the same.

Hp200 data cartridge, Intel MDS 800

by lemay＠cs.umn.edu

Inside the box of floppies for the Intel MDS 800, was a single tape cartridge. Its a HP200, certified data cartridge, series 9800. Is this something that can be used with a MDS 800, or is it something that someone else needs? -Lawrence LeMay lemay(a)cs.umn.edu

It looks like: >>> Do you see the system counting down in hex?

That will prevent an auto-boot, but won't keep the system from operating. It's not serious; just serious enough that they wanted to wait for some console input before going ahead. Go ahead and try booting it. > Yes, tried hooking up the AUI port too, but the thickwire > cables I have > won't fit!

I seem to be hitting dead ends That's odd :) They might be strange cables. > all over... but > will try to connect the thinwire to resolve the "??" > reported, and also make > a proper 9pin cable, then will see where that gets me. If you're getting the prompt, the counting in hex, and the CPU ID (something like KAXXX-XX, I think), you're doing fine in the cable department. I suppose if not, maybe the VAX prints its errors to all the ports on bootup. In that case, it won't take input from that port, and you'll need to get the right cable to tell it to boot. You still don't absolutely have to get the network connected, though.

[Semi-OT] Seeking Alpha Pc 104 Motherboard

by dougq＠iglou.com

The subject of my query isn't 10 years old yet, but since it's DEC equipment and there are many DEC fans here, I'd like to post it anyway. About six months ago, a list member offered me one of these Alpha ATX-factor motherboards for a very reasonable price. As often happens with many of us, the deal has not gone through. If anyone else still subscribing has a cache of these and is willing to part with one I'd appreciate it. I'd prefer a trade for a Calcomp Digi-Board III digitizer tablet with 16-button puck, but I could also trade a Mac Quadra 700 or Quadra 650 (as I have a couple extra). I also might have other trade-worthy items; just write me and we can discuss it. Thanks in advance, -doug q -Douglas Hurst Quebbeman (DougQ at ixnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away."
