Ok now I read it. Doesn't mean I'll remember. I forget stuff I write or
create myself.
Very cool though.

this hack works well with 8085, based on SOD,
I am working on an NSC800 version, so that "Z80" modified M100s can also
transmit video data out the BCR port.
Background:
SOD pin, normally used to drive the cassette port, can be used as
It is a hack I published on the wiki. It is used to for example drive data
to external video.
I can see I need to make my posts more fun to read!!!

BCR Out? I wasn't aware that the BCR had an output pin.

as a suggestion if you included a breakout for pin 2, you could also use
this for Tx out on BCR, in line with the "BCR hack" I posted at the wiki.
as an FYI, I have a MAX232 based adapter board that converts TTL to RS-232,
for use with the BCR port.
I could share that if there is interest.
I used
Thanks for making the BCR breakout board Brian! Definitely will come in handy.

I ended up making a separate breakout board for hacking/experimenting

Right!, Which they have in every direction and config you could want,
easy on amazon, ebay, aliexpress, even startec, lots of laces.
Then the kit is all very tidy.

I added a version that might or might not be more acceptable for NEC.
I have the pcb hanging down so the bottom edge of the pcb is just above
the bottom corner of the laptop. That positions the usb cable far enough
down that the very end of the molded boot is still below the top edge of

Thanks, Mike. Yes that's about the size I was looking for. I'm using them
to pull power from a BCR port, which is just 2 wires.
The slimmer the better. Like this:

I don't know about 9 pin, but Mike Stein found a really good 25 pin when I
was trying to find something good for tpdd cables.

If I wasn't on my phone I'd just try searching "dsub" on digikey and filter
by 9 pin instead of
Gary,
I may have some in stock. LMK if you want pics.

And by "connector" I really meant to say hood. The connectors are standard
but every hood assembly out there seems to be about 3x as large as it needs
to be...

Anyone know where you can source this style of D-sub connector anymore? I
like how slim they are. The only connectors I can find these days are
quite a bit larger.
