Or it could be a CD4016 which is the same. (Same pin layout)siggi wrote: ↑Sun Sep 02, 2018 2:44 pm That are 4 analog switches (IC version of a relay). Maybe a CD4066?

Re: Lambda colour kit
Re: Lambda colour kit
Hello to all,
I found a Lambda colour interface
and I'm trying to use it with a ZX81 modified for video composite output.
I connected the video interface input to the zx81 output, then I connected a cable on the interface video output (not analog TV).
When I power on the computer the screen is blue instead of usual white.
W/o powering off the ZX81 I use its direct video output and display appears as usually, and keyboard is working.
I tried to initialize the interface as said in manual (poke 12301,1 then initialize to 7 (black) memory from 8192 to 10240, then RUN, ZX81 seems to hangup...), and still nothing when back on interface output.
Is there a physical modification to do inside the interface itself?
Something wrong in init process?
The ZX81 has an internal 32KB memory.
Thanks in advance for any help.
Olivier.

Re: Lambda colour kit
The Lambda Colour Pack occupies memory from 8k - 16k. You have to make sure your 32k RAM does NOT occupy this area.
The Lambda Colour Pack has 1k RAM, but it occupies area 8k - 12k. Area from 12k - 16k is occupied to enable/disable the interface.

Re: Lambda colour kit
I have one as well, and have used it with the Lambda, but havn't tried it with the ZX81.
However since my color CRT broke, the interface has been put away.

is there a way to translate the pdf to english or at least an english copy of the document?siggi wrote: ↑Sun Oct 06, 2013 7:37 pm Some information about the color module can be found in the German ZX-Team magazine 6/1992 (at page 19) in Tom's forum:

See also page 13 of 1/1996

The schema can be found at page 14 of 2/1994

The modules offers additional color ram starting at address 8192. Poke this and the following addresses to set the color.

Re: Lambda colour kit
For translation, Google Translate is decent. But, looking at those PDF's, they don't appear to be OCR'd, so you can't copy the text from the document. About your only option is to hand type the critical sections that you need into Google Translate and have the German translated to English.
