nah, some voodoo gzdoom build will most likely be like the Quake2/DOS port - can't say I look forward to it the definitive way would be to add low-res voxels support to the classic dos engine , not sure how/if this can be done or if anyone cares enough - just thinking out loud here since I was …

Diodes have a 'polarity', so you have to put it in the correct way. I guess worst that can happen is it blows up again.

But it throws on each cylinder/head a format error!, Format retry, drive 0 recall error! Estimated time is 3h8m. IMG_20230418_100702.jpg FYI. it can't output to device PRN which is kinda an alias for LPT1 or the device to which a printer should/could be attached. The error message has nothing to do …

if you have a tl866 you can use it to find out the ID of the chip and then look up the ID in the infoic.xml file so you have the name for the chip. that's how I'd do it in windows. if you have a tl866 working in linux, the minipro program will suggest which chip it is using the id.

You set the path variable to the directory where the executable is located. Not directly to the executable. in your case that would be PATH=D:\; you can add more paths (directories) by seperating them with a ; as in PATH=D:\;C:\DOS;C:\UTILS; at least that's the way path works in dos. don't know if …

This is one of those monitors that uses Green Blue leds with red phospor coating to turn it into white. The driver for the green leds wasn't delivering any power due to one broken component. An SR5100 …

FYI, aside from scsi2sd you have rascsi, bluescsi, zuluscsi, and you can reflash the firmware on a acard aec-7722 to a 7726 and hook up a harddrive to it or a sata to ide converter to the aec. Just some more options for you to consider as harddrive replacement.
