It sure does. I think we have had that pop up on the list several times. It's a
good cable. But $36 is way too much. I build the same thing for less than $10.

Sorry, I wasn't clear in my description. I was talking about a regular USB to
DB25 cable, not a TPDD cable.

Hey John,
Sounds like it’s along the lines of my Pebble watch. It uses an epaper
transflective display that looks better the more sunlight available. And it’s
battery would also last a week.
Unlike the Fitbit though, you could write custom apps for it using the SDK that
was available. It’s
A tpdd cable needs to have a 2x4 female pin header with ttl signals on
one end, and a db25 male with rs232 on the other end.
Unless you wanted to make a tpdd cable that only connected to modern pcs?

The old serial cables do. But the new FTDI USB cables have a standard USB end
with the FTDI + Max232 chips in it and the other end is the RJ45. Here is an
example.
Don't the cisco cables have a rj45 on one end, and db9 on the other?
Don't you need a dupont connector for the tpdd, and a 9-25 adapter for
the M100?
And do they actually include dsr/dtr?
Myself I am hoping to no longer use the db25 pcb. I just made a new
version just for the heck of making a

I picked up a Amazfit Bip smart watch just before prime day for $60. It's

Brian,
I appreciate the insights. My first reaction to seeing your new board was that
this was a good solution. But after reading through your post, I changed my
mind. It's probably still much easier (and cheaper) to buy the FTDI cable
designed for CISCO routers, clip off the RJ45 end and then
Kinda sorta maybe possibly. I had thought about using one of the
variants of max232, instead of the 3 transistor hack. But in the end,
the 3 transistors is probably the cheapest and simplest circuit to make
a tpdd work, and this new circuit with the part that Rick Shear
identified, really

Ah, all good points! I didn't figure the ROM used IEEE floating point, but
I didn't realize how different it was!

Very interesting notice

Brian,
I noticed you have a new DB25 PCB on Osh Park. I suspect the whole TPDD cable
was intended to take a TTL level floppy drive and bring it to a standard RS-232
level. I'm wondering if that same PCB could be used with one of the inexpensive
TTL level FTDI USB to serial converters to create
Hey John,
I was reading the posts about posits ... pretty interesting.
But the Model T ROM doesn't actually use IEEE floating point format ...
It uses a format where the first byte contains the sign bit and 7-bit
exponent, followed by 3 or 7 bytes of BCD encoded data. For the
exponent, 40h
Kurt, no problem at all. You've done some nice work to accomplish this.
Very cool. Steve

Nice to see there's still work being done on the low level parts of
compander science.

I was using the "é" character, but I found the problem: Since I'm
using a QWERTY keyboard, I use numpad code ALT+130 to type this
character.

If there's a need for a PDF of the game manual, I have a good clean (iirc) hard
copy and a scanner.
