[M100] MiniNDP

2023-12-12 Thread Brian K. White
MiniNDP now supports 512k and the Bank button in RAM100.CO / RAM200.CO is functional. https://github.com/bkw777/NODE_DATAPAC#minindp Now to figure out how to operate it from BASIC to reimpliment the lost BOOT program that apparently could read a copy of RAMDSK.CO from the device without ha

[M100] Question about TPDD/FB100

2023-12-12 Thread runrin
Hey all I acquired an FB100 recently, popped it open and checked the belt, and it looks brand new. I spent a few hours building some of bwk's TPDD cables tonight and testing it out, but I'm struggling to get the drive working. When I connect the drive to my M100 and use the TS-DOS rom, the drive

Thanks Runrin, I was pretty happy with how the Pi Zero version turned out. I've had this setup in some form or another for several years. The original version of this was on a larger raspberry pi so I have used USB to serial adapters without issues. Initially the Zero was run off of a USB to seria

Wow Brian! This setup with the Pi attached to the back looks amazing. It's attached so cleanly as well. I appreciate you doing the `stty' at the end, hopefully mirroring your setup will help me get things working better on my end. I do wonder if the fact that you are using the Pi's GPIO pins to d

Thanks Mike, all good suggestions for sure but I was aiming to make the worst possible situation to push the flow control as hard as I could. John, before you questioned it I was certain, but now my memory may be failing me but I seem to recall the T200 stealing the flow controlines to run the lat

BTW, another tip: if you're sending a text file to the M100, send it without Line Feeds (i.e. only CR) if possible; that will save time since there's no scrolling, and that's how the M100 sends files anyway. On Tue, Dec 12, 2023 at 5:43 PM Brian Brindle wrote: > > This has come up in discussion a

I've never had any problems at 19.2K using Windows so, as John suggests. there may be Linux-specific issues. There are buffers in most if not all USB-RS232 adapters and also in the program on the PC at the other end, and sometimes these need to be tuned a bit. When I send a 25K file from TeraTerm

[M100] 19.2Kbps on the Tandy 102

2023-12-12 Thread Brian Brindle
This has come up in discussion a few times so I wanted to show that 19.2Kbps on the Tandy 100 is possible with only software flow control. Here is a video of me creating a 500 line 40 col file that is 20KB, transferring it to the M102 and back again using the 19.2Kbps serial connection. It gets sl
