#atari8bit

I've got this vintage #Centronics to #Atari #SIO connector. The last time I tried it (last year sometime), I could LPRINT a line from BASIC, but line endings weren't correctly interpreted. (Unsurprising; Atari uses $9B as its line ending.)

Coming back to it today to see if the adapter was configured to interpret line endings correctly, I mostly got timeout errors in BASIC and twice only, some garbage, while trying to print.

(Printing via the parallel port on a Thinkpad 760CD running Windows NT4 works perfectly. So it's not the printer.)

Any tips on how to proceed further with troubleshooting this connector?

A sketch of the connections on the SIO connector to the board in the Centronics adapter. All connections are accounted for and are good.
The business side of the little board in the Centronics connector. Three of the chips have stickers on them which I'm loath to remove. The 24-pin DIP chip has a sticker with the text "(c) 1984 WW ATARI20E". The 40-pin DIP has a sticker with the legend "WW 04-1986 Test OK: fp SN 17499".
A close up if a line of garbage printed on green bar paper. Most of the characters printed are not even in the ATASCII character set. At the end of the line is some valid text "0 DIM A$(80)"

There's been a bit of buzz in the #atari8bit #retrocomputing scene lately about #Fujisan, a cross-platform GUI wrapper around an updated version of the #atari800 emulator, which claims to bring #FujiNet-PC support.

I've tried it on a fresh install of Debian 13, and in my minimal testing so far, it appears to work and is quite straightforward to get working.

Fujisan can be installed painlessly from a DEB (github.com/pedgarcia/fujisan/r - it needed one dependency), and FujiNet-PC can be built by following (some of) the instructions at github.com/FujiNetWIFI/fujinet (In short, install the build prerequisites, skip the PIO stuff, clone the fujinet-firmware repo and run ./build.sh -cp ATARI. Start FujiNet-PC by running the run-fujinet script in build-dist).

In Fujisan settings, on the Hardware tab, select "Enable NetSIO (FujiNet-PC support)" and click OK. Cold boot the emulated Atari. FujiNet will start on the emulated Atari.

Kudos to Paulo Garcia for this work, and to @tschak, @mozzwald and everyone else who contributes to #FujiNet.

I'm looking forward to experimenting further with this.

A screenshot taken on my Thinkpad X240 running Debian 13. Fujisan is on the left, booted into MyDOS using FujiNet-PC, which is running in a terminal on the right, and writing its log to STDOUT. MyDOS shows a listing of the files on the MyDOS disk mounted via FujiNet-PC.
