Re: UCSD p-system manuals and disks?
So I have imaged the three disks I found using ImageDisk: http://storage.datormuseum.se/u/96935524/Datormusuem/TEXAS.zip Then I scanned one of the manuals. UCSD Pascal : http://storage.datormuseum.se/u/96935524/Datormusuem/UCSD-Pascal.pdf The problem is that manual has text in red/brown and black. I scanned it in colour. However the actual colour of the scan varies a bit between pages. (Maybe because there are two sensors, one for top side and one for bottom side.) And the scan get very big. Is there a way to create filter this pdf to use three colours and possibly compress it better? What is the best way to deal with scans of documents with coloured text. I know many DEC manuals that has coloured text as well. /Mattis 2018-02-20 17:19 GMT+01:00 Bill Degnan : > These may be uncommon, given they're for the TI 350-era business computer. > They were partially IBM clones, I am guessing the Pascal in particular > would have been incompatible with a regular IBM of the time and these disks > would only work on the TI's.

Yes, you can do that with photo editing programs, which often have scripting ("batch processing") features so you can do it repeatedly. Depending on the quality of the source material it may be hard to get right, though. One technique that's useful in dealing with colors in the way you want to is to convert the images to "Lab" (or "L*a*b") format, as opposed to RGB or CMYK. That separates the brightness information from the red/green and yellow/blue distinctions, and lets you apply curves, or threshold operations, or things like that to emphasize colors or force them to particular values. It will take experimenting with your particular source material to figure out the way. If standard programs don't do the job, an image file manipulation library might be the way to get at this. paul

I discussed exactly this possibility a few years ago with a now departed friend. We did a cursory search at the time and didn't turn up anything. Of course there are lots of smart people out there who do a lot of clever things and never bother to tell the net. My bet would be that nobody has wanted this enough to make their own omnibus front panel when there are still real panels and machines readily available. I guess you can be the first!

I do this for many vintage manuals that had been previously scanned that I've downloaded that have not been OCRed or optimized. BTW: OCR works best when the manuals are scanned for color or grey scale at 600bpi or better.

Re: More S-100 related hardware from Sellam's collection
Hi Sellam Can I ask a favor. I have one of those 8K Piiceon boards. There is one part I haven't figured out yet. Between IC19 and IC20 there two jumper holes. There is also a jumper hole just to the bottom right of IC23. Is there any jumper wires connected to any of these three points? If it is not asking too much. I think for what it is, your $40 is a fair price. Most don't have a way to program 2708s and this should be the same as the ByteSaver for that purpose as well as providing EPROM space for code. With the EPROM to use it, it is great. If I didn't already have one and a ByteSaver, I'd buy it. Mine doesn't have all the program control part across the top of the board. Only two sockets are populated. I spent about $10 to fill in the rest of the parts from Anchor. You should mention if it has programming control for all the socket positions. That might sway a buyers choice.

ISO: Harris Micro-12 (HB-61000) docs
Hi all -- Got me a Harris Micro-12 (AKA the HB-61000), this is a single-board computer based around the Harris 6100 (PDP-8 on-a-chip) microprocessor. I'm working on bringing it back to life and I'm trying to find docs and schematics for it. There's a high-level overview starting on page 5-4 of http://bitsavers.org/components/harris/1979_Harris_CMOS_Microprocessor_Volume_1.pdf, but that's the most I've found. Right now it looks like the FLAG 2 signal on the PIE chip (HD-6101, discussed in the aforementioned manual) is holding the 6100's RUN line low; I don't see anything telling the PIE to do that at reset, nor is anything else attached to that signal that I've been able to find, so I'm wagering that the chip is faulty at the moment. (If I pull the PIE chip out the CPU appears to be running.) Schematics and/or docs would make this a lot easier. Anyone have a copy of these? Thanks in advance, Josh

DEC VR150 montior
Does anyone have a schematic for this DEC monitor? I have one that has good video but doesn't seem to want to respond to video input.
