AY-5-3507 data sheet

[Reinhard Zwirner]

Dear experts,

Trying to repair an old Sinclair DM235 DMM I'm searching for the data
sheet of AY-5-3507 display driver(?) which is, BTW, cross referenced to
MP3202. Can anybody help? My highest degree of happiness would be
receiving the schematic of DM235 ;-) ...

Full of hope

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.

Full of hope

There is always hope

Hi Joerg,

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

So, what about this?

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.

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

<ftp://ftp.eskimo.com/u/m/mzenier/AY-5-3705.pdf>

5 pages, 168k bytes.

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

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 <ftp://ftp.eskimo.com/u/m/mzenier/>).

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).
