It had 2 disks with MS-DOS 3.2 or 3.3 and GW-BASIC and a third disk with diagnostics and turbo.com utility to set the cpu speed. Nothing special you can't do without, the speed is switchable with CTRL-ALT-ENTER too so you don't even need the utility. DOS was 'branded', displaying the Hyundai name when booting.
There is no BIOS setup or setup disk, just set the time using the DOS time command.
I know I'm getting around to this very late, but I would appreciate it if you imaged your DOS boot disk if possible, but all three would be best. The Super 16T and 16TE both have RTCs with battery backup, this does not seem to be able to be set properly in dos without some specific utility, I'm unsure if this lived on the factory hard drive or on the Hyundai specific boot disk, but the evidence does point to it existing. I was able to get a set of disks myself for the Super 16TE, but the boot disk is heavily damaged and I doubt I'm going to be able to recover much off it. With the rarity of the Super-16 series dos disks, they really do need to be archived regardless of how special or unique they end up being.
Can you please tell me what is the evidence pointing to it existing?
Also what happens when you set the date/time using the DOS commands (having of course a working battery)?
Well, to start, the Super 16T (Turbo), Super 16TE (and presumably the Super 16TM/XT but I can't find an ad) were marketed on having RTC function with battery backup. You can view the ad here: https://www.1000bit.it/ad/bro/hyundai/Hyundai … Peripherals.pdf note that the Super 16T has RTC+Calender with battery backup as a feature by default but the Super 16 does not. Though the Super 16 had the RTC/Battery as an optional add-on board but not by default. This tracks with the Super 16T/TE/TM/XT all having RTC batteries on the motherboard while the Super 16 has no battery on the motherboard. The Super 16T/TE/TM/XT also have RTC chips that can be checked with a Hyundai specific diag program that warns that Date/Time will be lost of the check is proceeded with. Implying they felt the need to warn the user at all. If the system was intended to be forgetting it's date/time every restart I doubt they would have bothered with that warning, or a battery, or the RTC chip. Reviews of the Super 16T+ series all mention sets of Hyundai specific software on the DOS boot disk but they do not go into specifics sadly, but the software suites seem pretty extensive based on the descriptions. They mention the GW-Basic and Utilities disks separately (I have these and they do not contain the suspected utility in question), so I believe this software for programming the RTC was either written to the original HDD at the factory or was included in the DOS boot disk and might not be readily noticeable/buried in another program like the "Electric desk" program Hyundai included. It might have been read only by a specific program but without the disks/disk images or manuals it's impossible to say.
As far as entering the time and date in dos, this only persists for the session. A restart wipes the date/time completely, which means that the RTC chip isn't able to glean the information it needs directly from the DOS time/date entry. To cover all my bases, I ran the RTC chip diag check to ensure it was still working, ran out and got a new RTC battery despite already having a good one, and double checked my battery holder's continuity to the board. Everything checked out, so the RTC *should* be functioning correctly. This mirrors the behaviour that has been seen in other threads where the RTC should be/is functioning but doesn't seem to receive any info from normal DOS operation. Attempting to enter the date/time again via the DOS Time/Date also doesn't produce any change in the computer's behaviour. I didn't expect it to, but I wanted to cover my bases.
This is why I'm trying to find these disks or an unlikely HDD image, there's something more going on with these Hyundai turbo XTs and it's sad to me that they remain lost media like this, it's very hard to investigate what could be going on without all the tools/evidence to do so.
