I much prefer DR-DOS to MS-DOS, but I'm quite fond of DOSShell (believe it or not.) Currently dosshell reports incorrect dos version when I execute it under dr-dos 7.03, and setver doesn't seem to have any effect on that. Any advice? Will PC-DOS dosshell work under DR-DOS?

Has anyone used an old version of PC-Anywhere with a serial/wifi bridge adapter to remotely access an old PC?

Supposedly they emulate a Hayes-modem over wifi somehow. Anyone tried this? How do you "fake" the connection into the PC over wifi, do . you need two of the serial/wifi bridge adapters?

I found references to a 1.2mb 5.25" 6.22 version, and a 360kb 6.22 upgrade set, so I guess my options would be to install 5.0, upgrade to 6.22 via the 360kb images, or create my own 720kb 6.22 set. I'll try the second option first.

I've got about 8 sets of genuine 6.22 1.44mb install media but I'm coming up blank on 720kb. I'd like to get it installed on my Tandy 1000TL but it only has a 720kb drive. I suppose I could install the drive in a system with 1.44mb floppy if I need to.

I wonder if the guy who decoded the SOundblaster CMS upgrade PAL would be up for trying these? I'll have to find his thread.

yeah. We'll see. Do you know of anyone off-hand that does this kind of work, and how much it costs? Not afraid to drop a little bit of money into a project like this.

you are looking into reverse engineering that aplleII hardware emulator card right? It was kinda disappointing seeing it has 8 PALs... it makes no sense sending them for cracking it will be too expensive for this many chips :( Yep precisely. The Trackstar 128 can be upgraded to an E by swapping …

I am looking a board with a lot of PAL16L8 chips (which are brute-forceable from what I understand) and a single PAL16R8 chip. My understanding is that the L chip is logic only, while the R chip actually contains some form of microcode. Presuming they are in fact write protected, have any advances …

I've got a handful of early IBM flat panels, model number 9507. They support rudimentary power saving via two PS/2 pigtail connectors that have passthrough connectors for PS/2 keyboard and mouse. I thought several of them were nonfunctional but it turns out they work well, but the proprietary power- …

How you define Tandy 1000 Soundcard ? with DAC? or only PSG ? I`m working together with dreamblaster, and i`m sure you can buy a working product these year at least with PSG. Also a LPT Plug is in the works, so you can use your LPT Port for 3 Voice Sound. A Friend at dosreloaded.de is activly …

Sadly …
