For the kinds of access you are looking for you really want filesystem level sharing, where DOS can read files but it can't assume complete ownership of the blocks. That's where things like NFS, SMB, and EtherDFS come in. There is also a new program called NETMOUNT that was announced on the FreeDOS …

Want to replace the caps on my PCChips M321 386 motherboard (https://theretroweb.com/motherboards/s/pcchips-m321-rev.-2.x) because of fast external battery drainage (see: https://www.vogons.org/viewtopic.php?t=105673). Found these two capacitors which seems to be a good match on Mouser: Panasonic …

I'll get the DIP sockets replaced and then fit those new caps and see if we get a fully set of lights on the POST card. Sorry for the bump but do you remember which caps you used? Want to replace mine too (same board, same crappy capacitors). Found these two as a good match on Mouser: Panasonic EEA …

You could do with leaving them in another day and checking voltage again. Reason I say that, is because if you measured them out of circuit initially at 1.6V, it could either have been a truly new fresh battery, or because modern meters pull so little current a part used or stale battery that would …

Had the same issue a couple of weeks ago. My issue was the 3.5mm cable I used that was too thin and picked up interference from power cables. But there can be other issues as well. For example a ground loop. There are some (US specific?) power line filters that can mitigate this. Also try to connect …

Nice you got it working. Maybe you also want to take a look at Backup Exec. It was quitte popular back then. Used it a couple of months again for my HP SCSI tape drive and it worked great.

Both nice motherboards. It's mainly a 100MHz/1024KB vs 133 MHz/512KB cache difference. Don't know how much memory you want to put in it but if you want to deck it out I would go for the GA-486AM. Else for the GA-5486AL.

In the end, what I've done is built a completely new system with an ISA slot because PCI sound cards suck in pure DOS. That would be the easiest way indeed but not all PCI sound cards suck. The above mentioned SOLO-1, ALS4000 and Yamaha sound cards work perfectly fine for 99% of the DOS games. That …

For PCI sound cards you can also look for an ALS4000. Got one of those and also the earlier mentioned SOLO-1. Both PCI cards work great under DOS.

Closed report. There is nothing wrong with charging for work performed. If anything there should be more of it, since people would then quantify their work and would likely help prevent burn out.

Can't give advice on what the best workflow is for these kind of things. But before you delve into this it's maybe a good idea to look if it's already available.
