Sound Blaster emulation for me works in some games. Prince of Persia is one of them. MIDI is not supported

I wanted to post back here since I found the issue. I added an XT-SD card and that didn't work either. It turned out that the motherboard was configured for 4 floppy drives, rather than 2. That got in the way of the HDD ROM address I guess, or maybe it tried to read the HDD as if it were an FDD...

Thank you! I was looking for that, but somehow I only found the user manual on Bitsavers. You think it could be one of the TTL chips that's shot?

That's what I was afraid of, and I understand it could've damaged the keyboard. But how could that have damaged the terminal? By directly connecting a voltage rail to ground or something?

The terminal does power on because when I switch it off, I sometimes see a garbled line flash really quickly. I'm afraid some controller chip may be damaged.

Hi all, asking this question here because I think this area of the forum has the most members who are familiar with terminal keyboards. I have a Morrow MDT 60 terminal with no keyboard. Someone told me that any keyboard with the same connector will probably work. I tried a Unisys keyboard, but...

How did you manage to get it to run off a compact flash card? I know this is an old thread but I'm hoping that you can tell me on which ROM and I/O address you were running the card, to avoid a conflict with the onboard IDE.

I replaced the battery twice with a brand new one. I'm afraid these errors will keep happening though, as long as I cannot boot into the diagnostics disk. I was hoping that the ROM on the XT-CF card would interrupt the boot process so that I don't need the FDD.

Hi all, I have installed this XT-CF card in my PS/2 Model 25SX but it won't bring up the option ROM of the card. I tested and used the card in an AST 486 and it works perfectly in that computer. I installed MS-DOS 6.22 on a 32 MB CF card. The PS/2 however shows error 161 and 163 (invalid CMOS...

Yes, that's it!

Does anyone know what brand and model this terminal is? It doesn't have any stickers on it, and I haven't been able to find similar looking terminals on Google.

I have serial #4179.

T-R-A (Dale) did an amazing job on resoldering the chip! Look at the mess it was, and what he managed to make of it in the end. He let me know that if anyone else needs work like this done, he's more than willing to take on other soldering jobs. He charged a fair price and most importantly, it...

I really appreciate your help. T-R-A is taking a look at it right now. Hopefully he can get the board back to life. It would be great to save this machine.

Thank you so much! That video explains a lot. I'm afraid I don't have the steady hand for this small chip but it's certainly been very helpful to learn more about soldering in general. Thanks a bunch for the helpful tips and the offer. I'll send you a PM. In terms of the pads; those are part...
