Does anyone have an old RS catalog need sheet for 304-611 bargraph

Hi to all,

Yes Eric, before you say it, its another antique part

I need the info on an RS bargraph module part number RS 304-611, its a 10 LED bar with what I believe is a LM3914 built in. See Pics

Also a pic of another antique I just found in the bottom of a box of bits, an RS clock IC still in its original box from god knows when

Knew I should have kept the old catalogs.........Doh!

I remembered this one from a couple years ago: ( link to a thread here on Electro-Tech, with datasheet )

https://www.electro-tech-online.com...m3914-integrated-led-and-lm3914-driver.19696/

Careful with the soldering, if I recall, back in the 70's when I used one, the PCB traces came up way to easily.

hi Al,
I have one those timers in a box 307-611 and I have been searching through the old datasheeta for ages, its circa 1980.! I'll look again tomorrow I'm covered in muck and spiders webs. I recall its 1.5V operation.

I see that Zevon has sorted the Bar graph.

hi Al,
You are out luck this time.
My Digital clock timer module is a RS 308-499 , about 4*2 cms.

Hi Eric and zevon8,

Thanks for the info on the bargraph zevon8, it gives me all the info I needed.

As to the clock IC Eric, I have discovered a floppy from many years ago with the correct RS number written on it (by me I assume) and it has a PDF for a clock IC but I am unsure if its the right one, I must have thought it was at the time!

Have a look, it also may be useful to anyone with the RS IC so I'll post it.

As to the painting, I bet you won't get far today, people around here are starting to build Arks! hehehehe
