    Loading dos high on a XT

    Thanks! So I used the above ranges on my 1000 SX. An Lo-tech EMS card is located at E000-F000. DOS and Checkit report weird memory configurations. If I use the PC DOS ram command, it reports 92 KB of UMB. According to Eudimorphodon, this can happen on Tandy 1000 and it is not a cause for...

    Xt-ide-cf optima

    I have the same card (XT-IDE-CF OPTIMA) in my Tandy 1000 SX. it seems to work fine, without any issues. Do i have to worry about the missing capacitors or if it is working fine, it will continue to do so?

    Loading dos high on a XT

    I was thinking the same thing, but someone far more knowledgeable explained me that the extra 128K is in the B area of the memory and, like Eudimorphodon said, is paged : Also, loading TSR and drivers in the A000h area works fine with Tandy graphics. I tried multiple Tandy games, and also...

    Loading dos high on a XT

    So I tried 704K.COM on my TX with 768K and UMB at A000-AFFF with the Lo-Tech 1mb card, but unfortunately, it doesn't seem to work. It just reboot the computer without any error messages. I tried it without anything else loaded just to be sure. Well, USE!UMBS.SYS seems to work well, so it's not...

    Loading dos high on a XT

    Thank you for making this utility configurable, it is very useful! I can now have UMB in my Tandy 1000 TX and SX. I was wondering if it is possible to have not continuous UMB? Does USE!UMBS accept arguments to take into account different memory range such as DEVICE=C:\USE!UMBS.SYS A000-AFFF...

    Cheap homebrew ISA->PC104 adapters

    Would this fit in an NUXT 8088 board (https://monotech.fwscart.com/NuXT_v20_-_MicroATX_Turbo_XT_-_10MHz_832K_XT-IDE_Multi-IO_SVGA/p6083514_19777986.aspx)? Or the adapter would overlap the other ISA cards? I would like to add a 5th ISA card and such an adapter might be a solution.

    Questions about EMS memory

    I think that I have a fascination about EMS memory. I purchased 2 Lo-tech 2 mb EMS memory cards. I installed one card in a 286 computer and 1 card in a 386 computer. I already had one installed in a Tandy 1000 TX. The driver is loading fine on all 3 computers. On the 386, I have Windows 3.11...

    Tandy compatible sound adapter on 386/Win95

    Hello, I am the owner of a Tandy Compatible Sound Adapter. Just for the sake of trying, I installed it on a 386 DX-40. In dos mode, it is working without any problems. On Windows 95, Windows report an unknown device and it doesn't work. I was wondering, would it be possible (in theory) to write...
