Re: [M100] Virtual cassette idea

The m100 can receive files via the cassette port from almost any audio source. The trick is to use a an audio transformer. Something like an 8 ohm to 1.2k ohm. The 8 ohm end connects to the output of the audio device. The 1.2k ohm end connects to the ear end of the m100 cassette cable. I have

Re: [M100] Model 100 serial port

Testing thus far reveals that pin 25 of the UART doesn't fluctuate at all. It sits a 6.7 volts even when I'm not sending data. I wrote a BASIC program that sends a character, waits a half a second then sends another. I'll do more testing but my first impression is that it's the UART. Kurt

Re: [M100] Model 100 serial port

Is there somewhere a description of how the DVI interface works, and what signals (type & speed) come out (and where) of the Model T ? Did you need to load any software on the T to make it work, or was a simple screen 1,0 enough ? Is there a general description of the workings of a DVI,

Re: [M100] Model 100 serial port

Correct; the HC is definitely a better replacement for the 40H, but I'm pretty sure that in a pinch the HCT would also work. m - Original Message - From: "Francesco Messineo" To: Sent: Wednesday, August 02, 2017 1:05 PM Subject: Re:

Re: [M100] Model 100 serial port

Other tricks that might be helpful: - for another alternating bits sequence, repeatedly send capital letter "U" (a different sequence of alternating ones and zeros). - for a long pulse, set the baud rate to the slowest speed that the serial port supports and then send 0x00 or send 0xFF On Wed,

Even easier, in BASIC open the com port & set up a loop which sends 0xAA each time through the loop On 8/2/17, Kurt McCullum wrote: > Thanks John, > > That sounds doable for me. At least I'll be able to find the culprit. At 300 > baud I should be able to pick up a

Re: [M100] Model 100 serial port

Thanks John, That sounds doable for me. At least I'll be able to find the culprit. At 300 baud I should be able to pick up a signal. Kurt -Original Message- From: M100 [mailto:m100-boun...@lists.bitchin100.com] On Behalf Of John Gardner Sent: Wednesday, August 02, 2017 9:24 AM To:

Well the good news is the problem is somewhere between the db25 and the UART :-) -- John.

Mike, that reminds me of an old joke. Q: How many programmers does it take to change a light bulb? A: None. It’s a hardware problem. All kidding aside. Yes it’s probably an IC somewhere. I’ve done my fair share of board work over the years but tracing this down and repairing it is likely

Re: [M100] Gopher

Hey John, For a WiFi enabled Model T using a Woolly board, Gopher is the main protocol I was thinking about. Trying to support HTML / Flash / Javascript, etc. on a machine this old with a 40x8 LCD would be a bit futile I think. If (or should I say when) Woolly becomes a reality, it would

Re: [M100] Model 100 serial port

Well it’s officially a dead serial port. When connected to a PC I can receive but not send data. I then took a loopback cable and put it on the M100. Nothing! Not sure if I can fix it or if I should part it out but for now I’ll set it aside for another day. Kurt From: M100

Re: [M100] Model 100 serial port

Thanks John, Yeah the chunky cable thing is an issue but I’ve got a 25 to 9 pin slim adapter for that. I can receive data but not send. I’m breaking out some testing cables that I used a couple years back to see if I can get it working. If there isn’t a difference then I have a bum serial
