    Issue running PS/2 Model 50 setup

    I bought a new battery and it still didn't help. The next thing I did was pull out the drive and take a close look at the caps. Sure enough, two of the electrolytic caps leaked on the board. I put the hot air gun on it to remove them and immediately smelled bad fish. :) On closer...

    Difficulties in creating a PS/2 reference disk

    I'm a professional software developer....so yeah. "This should work" is my middle name. LOL

    Issue running PS/2 Model 50 setup

    Ah, good point. When the computer is on, I can confirm 6.0V is at the battery terminals. And, of course, I made sure the polarity was correct. Pardon my ignorance, but is there some kind of different chemistry the lithium batteries provide that a simple bench PSU does not (that matters)?

    Issue running PS/2 Model 50 setup

    I guess I will have to bite the bullet and just buy one. lol. I will do that tomorrow. I was just hoping to play with this thing tonight. Thanks!

    Issue running PS/2 Model 50 setup

    Evening, everyone. I finally got the reference disk created for my PS/2 Model 50 Z. The battery that came with it is only showing 2.0V. Unfortunately, I don't have any spare batteries at the moment. I thought about hacking something together with some AA's this weekend. However, I'm not...

    Difficulties in creating a PS/2 reference disk

    I got it to work!! I looked at that file 15 times and it did not occur to me that the file size was wrong. Someone even asked me if I was sure it was 200K. I'm such an idiot. It's been a LONG week. lol I have no idea how I managed to corrupt that 1.4MiB file into a 200KiB one. Thanks to...

    Difficulties in creating a PS/2 reference disk

    **UPDATE** OK, hang on....I see that I was really doing something wrong. That image file is corrupt. Stand by!

    Difficulties in creating a PS/2 reference disk

    Looks like you copied the entire 1.44MiB. Mine doesn't get that far. I'm really starting to think I just have some bad disks. I'm going to see if I can find others. **UPDATE** I found some more floppies. I'll try those and report back. :-)

    Difficulties in creating a PS/2 reference disk

    Ugh. That's pretty much what I'm doing. I use Fedora but I can't imagine that has anything to do with it. Until I can figure this out, I don't suppose I could get those files zipped up and I will manually put them on the disk? Or, better yet, how can I decompress the image? I tried Peazip...

    The image is 221,184 bytes. http://ibmfiles.com/ibmfiles/ps2/hamilton/rf5060a.zip Thanks!

    Difficulties in creating a PS/2 reference disk

    Weird, everything about the commands seem to work just fine. But the disk is blank. Here is what dd reports after I did another format: 432+0 records in 432+0 records out 221184 bytes (221 kB, 216 KiB) copied, 24.192 s, 9.1 kB/s

    Difficulties in creating a PS/2 reference disk

    Well, ufiformat seemed to work. I unmounted the disk, formatted it, flashed it with both dd and balena, mounted...and still blank. FYI, I was wrong about IBM providing this disk. It was from "IBMFILES". Not affiliated with IBM. Anyway, the image I am trying to download is below. I assume...

    Difficulties in creating a PS/2 reference disk

    You're right about the constantly polling. I took the disk out and thought to myself...is Linux just like Amiga? LOL I'm doing a raw format with ufiformat now...

    Difficulties in creating a PS/2 reference disk

    Yes, I'm sure. I can see and hear the drive spinning. This is what lsblk reports: NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS sdc vfat FAT12 PS2REF 7716-7D8A 1.4M 0%...

    Difficulties in creating a PS/2 reference disk

    I tried without the sync bit and the same thing. The system logs don't seem to show any issues with it. In fact, I don't see errors anywhere with it. I might try that belena. But if you're using dd, then I wonder why mine isn't working. Thanks. **UPDATE** I tried Balena and it said...

    Difficulties in creating a PS/2 reference disk

    Recently, a very nice PS/2 Model 50 Z has come into my possession. Turns out you can't just go into the BIOS like you can on other x86 based machines. In fact, you need to boot off the reference disk from IBM. I downloaded the disk from IBM (amazing it's still available!) but I cannot seem to...

    Next Project: Laser 128 with invalid voltages.

    Thanks for that information. However, I have some good progress. So I removed the 74HCTLS244N and noticed the voltages actually dropped again. Then I noticed ANOTHER 74HCTLS244N was also getting hot. Fortunately, that one was socketed. So I removed it and then got video with white squares...

    Next Project: Laser 128 with invalid voltages.

    That was a great idea but, unfortunately, it didn't work. I turned VR2 in both directions and it went from 0.1V to 3.3V. So I'm wondering if it's bad. UPDATE OK, so I let it run for a little while and noticed that U19 gets extremely hot! I mean, so hot that it would burn my fingers if I...

    Next Project: Laser 128 with invalid voltages.

    Hmm. I think I linked the wrong manual even though I thought they should have been the same. Here is the exact one I am using: Reference Manual As for your comment on Q1 vs Q3, I have no idea. lol. What I did was probe the motherboard and read the silk screens. What I recorded was what...
