I think it would be kewl to have a clik! drive for my calc or sometype of a drive. I got My graphlink for only $15.

I NEED MORE MEMORY!!! I NEED MORE MEMORY!!!

now THIS is something i'd actually BUY if it was being manufactured, but it seems i'll have to make one myself if it comes to that...

this is a little off-topic, but it has to do with linking...

how do i use that Telnet program? i mean, how do i connect it to the phone line? where can i find more info on building calc-to-phone adapter things?!

The phone to calc thingy is a gray graphlink cable connected to a modem, i think.

You also need a null modem cable/adapter. If anyone could tell me what pins go where in a null modem cable, I would be very grateful. I have quite a few 25-pin serial cables that I never use and would like to make one a null modem cable.

heheh, i actually got this thing to work awhile back... uh, here's what i did. i took the gray graphlink, put it between the calc and a male-male 25-pin serial adapter. within that adapter i removed pin 20 so that the calc wouldn't drain the dtr on the modem and make it think it wasn't connected. on the other side of the adapter i hotwired pins 4 (i forget whether it was 4 or not... find any pin that has power on all the time) and 20 to fake a dtr signal from the computer. the i took a null modem cable that had 25 pin on one end and 9 on the other (null modem cable is just a serial cable with the send/receive wires flipped on one end)... plugged the 25 pin side into the adapter and the 9 pin into the modem. figured out the authentication string and everything and got my email! only problem is its hard to type fast on the calc keyboard but its still fun. if you need any more help just email me... uhh, forgot to change my email... should be josh@pacificds.net
Hope it helps!

Calc <--> grey link (no adaptor) <--> null modem adaptor <--> male gender changer <--> modem <--> phone line

A parallel or serial cable will cause this not to work- you must get the gender changer (it sucks- at Radio Shack, the gender changer and the null modem adaptor cost $6 each). I think it has to do with impedance.

maybe that'll work for your modem, but mine wouldn't establish a connection until i had tricked it into thinking it was connected to a computer but making the dtr pin always on. that's where the hotwiring comes in :)

you need a GRAY GRAPHLINK or a PICLINK. The black one will not cut it. Plus, you can use a standard modem that is external. Old external modems use serial ports to connect. Once you have connected a modem to your graphlink and graphlink to calc, you need to connect a phone line to the modem. That is how it works, i think...

hey guys... about 1/2 year ago i actually built two of the ir links... sami was a big help, even sent me some parts (when i paid him of course) and offered general help. while the irlinks are very very neat they're not near fast or powerful enough. i only used 1 ir led and the range wasn't that great... i couldn't even get it to work with my television. i was able to play tetris and chat but for file transfer they're way toooo slow... but for the price its a great hobby. hopefully he'll be able to come out with a faster, longer range device with some software HE wrote to go with it.

Gold plating the ends of the link would work very well, IF you remember to remove the gold from the places where the black bands were visible before.
I know- we gold plated stuff in chem lab and my newly gold-plated 83+ link actually transfers programs faster now than it did when it was new! I can't say why, I just know it does!

How ironic...
Today in Chem we gold plated pennies...too bad i didn't read this article yesterday!!!

I bought a black Graphlink cable for my TI-85, only to find out that I need the gray cable because my computer is an ancient 486 running Windows 3.1. Any ideas on how to build a gray cable (ie. which pins to what part of the adapter)?
