AY-5-3507 data sheet

Can't help you there but I can't imagine that the MP3202 could possibly be in such an old instrument:

Probably a duplicate numbering because it sure ain't a display driver.

There is always hope :-)

Hi Joerg,

As to this type of MP3202: I'm afraid you're right.

So, what about this?

Best regards

Possibly the information is wrong. General Semiconductor was acquired by Vishay but chances are that the old datasheets and all that have ended up in the dumpster. Maybe someone has an old databook? That's why I keep those but unfortunately I don't have that one.

I have scanned the 5 pages from my 1980 databook and zipped the jpgs.

Haven't done this for a while... From the 1977 GI databook

I wonder if the old readership of sci.electronic.components is still subscribing?

Thank you very much! But, unfortunately, it's the user manual I already have ...

Ah, the problem with hand typed urls. And I double checked it, or so I though. Well, the part number on the file at the server is correct... (Workaround, go to the directory with ).

Here's some hints.

Jpegs aren't good for scans of line drawings. They either bloat or the quality sucks if the compression is too high.

Use monochrome pictures with a one bit per pixel based file format with compression. The Group 4 CCITT (fax) compression on a monochrome image (that's one available mode for tiff or .pdf files) will get you 30-50k bytes per page. .Gif or .png are pretty good, too, but about twice that.

The OCR/font based systems like djvu or the one (whose name I don't remember) in newer .pdfs is even better, maybe 3-5 times smaller. (But I don't have the software to create those or even view some of them. As a neo-luddite late adopter, version 1.2 or 1.3? pdfs seem to work best).
