    Eh, I guess I can live with that. There are plenty of other ways to play with a VLM these days, although it really isn't something I was planning to use anyway.

    You shouldn't have any issues with a Toshiba unit. If you need any help with it feel free to ask. I have two units myself (one has bad ports I need to troubleshoot!). Use good DVD media to burn home brews. The Verbatim 97016 worked for me quite nicely.

    That is amazing!!   I finally get to try this game and mark this off my bucket list.

    Downloading the .iso now.  Thank you "Edge Connector"!

     

    While I wait for the download, at bit about the show it was based on:

     

    You're very welcome, but I must give all the credit to @emceebois(Twitter) for acquiring and dumping the disc. Without his efforts, it would still be out of our reach! Enjoy. -AltRN8(aka Edge Connector)

    Very cool! Grabbing now.

     

    I suppose no one has hacked up a full version of this? I speak as someone who probably owns half a dozen full versions of the retail game and can provide the WAD no problem. 😆

    So I have looked into this quite a bit, and the issue is in how the wad is loaded into memory and not read from the media. In the doom port, the MPE used for the game execution would also be required to read the CD-ROM. Since it is a quick and dirty port, they basically created a ramdisk to load the WAD and read from there instead of doing the negotiation between game execution and disc reading. If a WAD is below the RAM size, you can load it, but if it is above it, you will have issues. The changes to the code to make it read off of the disc were significant enough that I didn't try taking it on. If someone good at hardware hacking could help us add RAM to a NUON DVD, that could open up a lot of options.

    Hi all

     

    After letting the dust settle for several years on my beloved N504 to my shock when I tried it the other day it couldn’t play nuon games or dvds and really struggled with music cds. When I last used it it worked perfectly. Is this a common issue? It was making lots of sounds like it was really trying to read the discs! Please help!

    Sounds like it could need a new laser.

    Alrighty folks, I'm still working on putting together a VM with all of this configured, but thought I would release this to the folks with an old RedHat environment already setup. I've uploaded the .gnupg files and the bless files to archive.org here: https://archive.org/details/tempest_202205

    WOW - it works!  I burned to a Sony branded DVD+R and it loaded right up in my SD2300.  Please share the details on how you got this to finally work.

    Glad to hear it! I'll be compiling some examples and trying to make a DVD multi boot disk and will be releasing the info shortly. Guess I'm not a scammer, huh. ;)

    Toshiba may not work, last time I burned homebrew game it did not boot. It worked fine on Samsung model, but sadly mine broke.

    This is signed to run from DVD not CD-R. The CD-Rs aren’t loadable on the Toshiba model which is why it would not have worked for you in the past. If you still have a Toshiba burn the image to DVD and give it a whirl!

    On operations above 1M--the control circuitry works perfectly in 4M mode. The problem comes with the memory chips it was designed to work with. The 2M Zeropower RAM (or NVRAM) chips are super finicky, especially as the majority of them available for sale are used. The used part isn't a major problem in and of itself, as the SAMS card doesn't care if the memory is backed up or not--so a dead battery isn't a problem as long as the RAM still works. Carefully cleaning the leads and soldering the memory chip to the board without a socket seems to be the best formula for getting the board to work in 4M mode--and assums you have two good chips. We have built several of them this way. Socketing the 2M chips results in just about every chip exhibiting some kind of problems (even the four new ones I bought as reference chips).

     

    The real issue is cost though. The memory chips are generally unavailable for less than about $25 each, with no guarantee they still work (used). New chips are about $120 each, directly from the manufacturer (Maxim still makes them). When I can get a pair of 512K chips for about $8 each (worst case), that makes a serious difference in total board cost without a lot of gain at this point, as almost all existing SAMS software is designed for use in 1M or less. I may eventually do a redesign that expands to 4M or even 8M using 512K chips, as that would actually be a lot easier to build and support.

     

    As to online information, pretty much everything on it can be found here on AtariAge (and I haven't really taken the time to put anything on the website I own yet).

     

    The board is actually a further development of the original Asgard AEMS and Southwest 99er's SAMS cards, as desgined by Jim Krych. The newest boards maintain full backwards compatibility with them. Arcadeshopper also has a sidecar variant for use by folks without a PEB. There are now enough of all SAMS variants in the wild that it is becoming a base requirement for a lot of newly developed software.

    Thank you for all the details. I'll keep digging through the Atari Age forums for information. I'm new to the Ti99 in general so I've got lots to learn.

    Thank you so much for responding! Thanks for confirming the part number I'll get it ordered right away. I'll also make a note about the misnumbering (I've done this myself so I can so relate!) I've ready that these boards don't really work above 1MB can you confirm that is true? also thanks for the diagram I was digging around for something like this to help with understanding how everything is put together. Is there any other web repository of information related to it? Thanks for designing it by the way.

    I'm doing a SuperAMS build with a blank board I purchased from ArcadeShopper. I think the BOM list was off on the web page as it seems to be the list for the 2016 version and I received the 2017 version. I'm having trouble identifying one chip on the board and hoping someone knows what it is offhand. It's the chip in socket U17 which I think is 74LS373. Can anyone confirm?
