TI Programmable 88 - What we missed... - Joerg Woerner - 03-06-2012

Just read the contents of the 428 pages USER'S REFERENCE GUIDE for the TI Programmable 88 and you understand what we miss...

Yes, it is THIRTY years since TI canceled their most exciting calculator project.

Maybe they cancelled it because the HP-41 already existed for a few years at that time;-)

They canceled it because they lost a fortune with the TI-99/4, had already a delay with the CC-40 and had - after the third or forth redesign - still issues with the 4-bit processor brain.

The manual is missing 407 pages. Do you have a full scan available?

Anyone interested in starting an emulator for the TI-88???

Re: TI Programmable 88 - What we missed... - David Ramsey - 03-07-2012

If you'd like a good scan of the manual, without all the bleed-through, let me know...


Re: TI Programmable 88 - What we missed... - Olivier De Smet - 03-07-2012

With the roms and hardware docs why not?

I had a 58C in 1982, cheaper than my 41cx I bought in 1986 :)

P.S a 42s emulator is soon to be publish for android ...


Re: TI Programmable 88 - What we missed... - Eric Smith - 03-07-2012

That would be nice!


Re: TI Programmable 88 - What we missed... - Marcus von Cube, Germany - 03-07-2012

I'm interested.


Re: TI Programmable 88 - What we missed... - Geir Isene - 03-07-2012

Please.


Re: TI Programmable 88 - And why not a simulator ? - cgh - 03-07-2012

Hello TI fans,

We were speaking about to "bring life to the TI-88" on our forum in Silicium.org.

Here is the thread (in french): http://www.silicium.org/forum/viewtopic.php?f=46&t=30341

We were more thinking about a simulator (like free42), instead of an emulator.

If people want to join us, for programming, or giving all kinds of informations, documents, manuals, everybody is welcome !

At this time, I do not believe that something has started, except the nice graphics by Charognard

Remember: "They don't know that is was impossible, so they do it"

Re: TI Programmable 88 - What we missed... - David Ramsey - 03-07-2012

OK, lemme restate that...

If you (Joerg) would like a good scan of the manual without the bleed through, send me a paper copy of the manual and I will scan it for you.

I got pretty good at this a decade or so back when I scanned hundreds of paper listings of old HP calculator programs...


Re: TI Programmable 88 - What we missed... - Dave Shaffer (Arizona) - 03-07-2012

How do you skip the bleed? By setting a threshold somewhere in your scanning program?


Re: TI Programmable 88 - What we missed... - Joerg Woerner - 03-07-2012

David,

Same question: How do you do this?

Ther original manual is from awful quality and I failed with binarizing it and decided to stick with 8-bit grey scale.
I spent 40+ hours in February and early March to scan and photoshop it(align, contrast, re-size, moving notes to the right position and removing ton's of speckles).

Should we re-do it?

Regards,
Joerg


Re: TI Programmable 88 - What we missed... - Gene Wright - 03-07-2012

And, I still thank you both (David and Bill) to this day for doing all that TI documentation (and some HP) scanning! :-)

Hope all is well.

Re: TI Programmable 88 - What we missed... - Garth Wilson - 03-07-2012

When you scan, put a black piece of paper behind the page. Increasing the contrast digitally helps too, bringing white paper back up to white while black ink is still really black.

Hi Garth,

You beat me to the same recommendation. A few years ago, I did some scans of TI User's programs. I put a black piece of paper behind them, did color scans, which gave the page an overall gray background. Used a photo editing program to increase the contrast ratio, which caused the gray background to disappear. Then converted back to b/w tiff. Results came out pretty good.

The scanner software that comes with most new scanners can probally do all this in the initial scan.

Re: TI Programmable 88 - What we missed... - David Ramsey - 03-07-2012

As others have replied, the "black piece of paper behind the scanned document" is the big trick. Tweaking contrast and a couple of other settings helps, too. It's pretty easy, really, especially if you have good scanner software.

I'd be happy to give it a try. I have several good scanners here; the Fujitsu ScanSnap scans both sides of a page at once and does an amazing job of image processing to remove bleed through and speckles. If that doesn't produce a better result, I have a Canon photo scanner and some really good software for it as well.


Re: TI Programmable 88 - What we missed... - David Ramsey - 03-08-2012

I have yet to restore the FTP files that resulted from all that scanning. My original server, circa 2003, died last fall and I had to make a panic run to the Apple store to replace it. I should do this...

This helped so well with individual two-sided printed pages on scanning for the "PPC DVD", that I permanently taped a black sheet of construction paper to the inside of the scanner lid.

You might want to try to scan with a pure black sheet of paper behind the page, this will reduce the bleed-through significantly (might even eleminate it). Then do some contrast adjustment. At least this is how we did it "back then" :)
