Thanks, that's already far older than anything I had! 😁 Now if someone can just find a pre-4.0 version floating around somewhere. Scott
Looking for old copies of the "Galactic Warzone" BBS Door Game
Posted on 2023-11-13, 02:03
This is going to sound like an odd request, since I'm the guy who wrote the thing... but I'm looking for old copies of Galactic Warzone. By scouring various websites and search engines I've managed to find galwar76.zip, galwar75.zip, galwar73.zip, and galwar61.zip. That makes 6.1 the oldest in my …

Hello, I've been trying to get this thing to work with Convergent NGEN machine, and I was wondering if the author (@retrocanada76 ?) or anyone else here could answer a couple questions. I'm new to FPGA work, but I was able to get a mostly functional understanding of the code. The mce2vga works fine …

Turns out I was just programming the wrong file or an incomplete set of files. One of Keropi's posts in the thread showed me the way. The cdf file references the sof file. I needed to program the jit file. After programming the jit file, I have video! Scott

Are there instructions for programming the FPGA board? I'm new to FPGA. I've downloaded the Quartus software and installed the USB Blaster II driver. I downloaded the firmware from github, opened the CDF file, and hit the Start button. It says 100% successful. Is that all there is to it? I can't …

Welcome aboard, opticpow. Will be interesting to hear your experiences with the Xi 8088. I've been having pretty good luck with mine lately. Scott

So how did you resolve your floppy drive issues, and the NMI issues? Was it all from switching away from the compactflash adapter? Scott

I've had some developments: 1) I built a new backplane using 30-microinch gold plated edge card connectors 2) I put the Xi 8088 back in to do some stability tests I was able to run Champions of Krynn for about 36 hours without incident until I had to clear the workbench to make room for another …

Still not sure why my gotek boots as A when jumpered for S0 on the middle connector of the cable; isn't the far end supposed to be drive 0? Maybe this is a funky cable as well. Floppy cables are weird. My understanding is floppies are usually jumpered to respond as drive 1, and the split+twist …

Result of my weekend testing... Krynn ran solid for approximately 48 hours until I shut it down this morning. This is using the "4GB Top Ram" card that Sergey recommended. Swapped one of my old 64 MB cards back in and it failed within an hour. So I'm pretty confident in concluding that my system, as …

I haven't upgraded to 0.9.4 yet. I'm still on 0.9.3. I'm just running one 1.44 MB drive. I believe my XT-IDE is at C800. Scott

How do you have yours jumpered? From left to right, I have SW1-2 on, SW1-8 on. Everything else on the board is off. JP1 is uninstalled. I do not have a ROM installed. The 1.8432 Mhz oscillator socket is empty (I have probably never used the serial port). C17 is missing (did I forget to install that …

It won't boot from my Sergery self-assembled floppy board, "Boot failed. Press any key to continue." That card works well in another system. I booted mine from the floppy board this morning. No issues. I do not have a ROM on the floppy board as I believe the BIOS supports it directly. I do notice …

Great! I'm looking forward to hearing if this resolves your stability issues. I've ordered all the parts I need to build a new backplane, with quality gold-plated connectors this time. It's always troubled me that my system if left unpowered for a few days, it'll require some jiggling of the CPU …

After ~ 36 hours of continuous success, I reinstalled the compactflash adapter and booted from it. Krynn failure within two hours. I tried a different flash card (Fuji), failure within 2 hours. I'm now running it with a Viking card. We'll see if it does any better. One thing in common about all of …

I have been here with the xi8088. Make sure you have four or five expansion cards installed before celebrating stability. The Micro 8088 does have sip resistor pullups on the data bus and some of the control lines, and given that seemed to be where I was having issues with the Xi 8088 (specifically …

It's been well over 24 hours now, and Champions of Krynn is still running on the compactflash-less computer. I'm pretty please with how this is working out. I'm going to extend the experiment to a full 36, then I'm going to reinstall the compactflash, and see if the bad behavior returns. Then I'm …

thats interesting. I noticed mine hangs a lot with disk access, I put it down to something like DMA and timings related to memory accesses. I used "Champions of Krynn" as one of my stability tests, and one of the things it does is disk access. It could be why in the past when I've thought I had …

I got rid of the compactflash adapter and I'm seeing improved stability. Anyone else try that? To early to draw any concrete conclusions at this time. I notice Sergey's compactflash adapter doesn't have a data buffer, whereas some of the other compactflash adapters (current Lo-Tech, etc) do. Scott
