I was flipping through my new “The Complete Guide to NetWare 4.1” and noticed it mentioned syncing time on NetWare servers to external sources. This got me to wondering what server administrators might have used in the 1990s for setting time on their NetWare 3.x/4.x servers. Today we use NTP over the Internet, or GPS […]

I’ve had an Adtran Total Access 908e (TA908e) VoIP/voice gateway for over a year now with the intent of replacing my collection of Cisco ATA and Grandstream ATA for the BBS and other modem stuff. Allegedly it does a better job at VoIP processing and gives me better line density, but first I need a […]
TL;DR: re-re-patching vintage Turbo Pascal programs so they work in modern times on modern hardware Wildcat! v4, a MS-DOS based bulletin board system was written in the 1990s in Borland Turbo Pascal and was not completely Y2k compatible. Internally the Wildcat! database understands the four-digit year just fine. (Wildcat! was not the only BBS software […]
Some new additions to the modem teardown album: US Robotics Courier 9600 HST (manual, photos), “widebody” FCC ID CJE794FAST. This is similar to the 14400 HST I already have in the album, except this one takes 16 VAC power with a male DIN-5 plug. A PDF of the manual already is online at vtda.org, […]
I finally reached the point in my vintage gear lifestyle where I needed to replace old Dallas realtime clock chips that have dead batteries. I opted to try to find replacement chips, taking a gamble with “new old stock” units, instead of trying to grind down the side of the chip casing to attach leads […]
The Internet Archive is invaluable when working with old hardware or software when you need to go look at old version of a website to find manuals, drivers, or general info. Unfortunately a great number of files lived on FTP servers because the web wasn’t really up to hosting them in the 1990s, and many […]
TL;DR: I complain about my failings and show off pictures and log files. Later some gradual understanding of ISDN and why this probably won’t work with my particular version of the Courier I-modem with a U interface. Turns out U is electronically incompatible with S/T. In my telcom fiddlings to get a 56k dial-up modem […]
TL;DR: replaced LH1056 solid state relay / optocoupler at U3 One of the USR Courier HST modems I purchased recently had a peculiar problem that if I plugged the phone line into the “wall” jack of the modem it returned NO DIALTONE when I tried to dial something, yet I was able to dial something […]

After proving my HST worked in my previous post with an ATX power supply, I went looking for triple-output power adapters (5 VDC, 12 VDC, -12 VDC). I finally found something that works, an ELPAC WM113TT AC-DC power adapter along with a new female DIN 5 connector. 21-Jul-2025: update to the update below, may have […]
I picked up a couple of “widebody” USR Courier HST modems and have been working through documenting power adapters for them and sorting out what goes with what. I figured out almost all Courier and HST models have different power supplies and voltage requirements. I’ve been tracking down manuals and cross-referencing the FCC IDs in […]
