Hello! Just got a Supermicro S2DGE mobo. Testing it with one SL49P Xeon 700/1M Cascades CPU (2x SL49R 700/2V are on the way) and got an issue. Everything fine, except microcode error and wrong frequency show on BIOS summary screen (550 MHz), but actually CPU is working at 700 MHz. I assume it is …

Possibly the earlier / lower specced model (110Mhz BT485 RAMDAC) mentioned here https://www.nextop.de/NeXTAnswers/1618.html Interesting. This is the "crap" version. lol Could probably replace the RAMDAC with a 135MHZ one, or 175MHz/200MHz if I could find one. Just need to figure out RAM, if its …

I haven't posted in a long time. Hope everyone is doing well. I bought this tonight (SEE PHOTOS AT BOTTOM) via ebay. I already have a #9 GXE VLB with the two different types of memory (VRAM/DRAM socketed), which is also seen HERE (taken from http://www.amoretro.de/): number_nine_9_gxe_vl_vlb_front. …

I could not care less. You say "I could *not* care less". Correct usage on the phrase ;) https://youtu.be/om7O0MFkmpw Back on topic You could argue for low end 486's that behave more like a fast 386 but your looking at the fast end of socket 3 (66-133) which is already too fast for a lot of games …

So, I don't have photos yet, but I have 8-10 shelves worth of games, double-deep and stacked. So..hmm...360+ games? maybe 400+ or more? I'm going to have four games buried with me that are signature games from my childhood I still play today. Dune II, Star Control II, Falcon 3.0, and Doom II. And …

Can't wait for this project. Awesome. Speaking of which, I think I have a box of, like, 20-30 AWE64's somewhere. That was back when they were a dime a dozen.

Holy shiz, thats an old photo of my collection... The case from the 2nd upper left? With two 5.25" and the floppy drive slot in-case? If that's the one, I don't know who made it. I'll see if I still have it (probably do) but from what I remember the buttons on it suuuuuuuck. Very flimsy, ultra-small …

I always snatch up little MHz displays on ebay that are inexpensive. I love 'em. Something about the switching of the turbo button from 8MHz to whatever (16, 33, 40, 60Mhz, etc) gives me goosebumps. Yes, I'm seeing a therapist. Would be interesting to do a DIY one. When i get time....

Btw, if you have VMware, you can pass that USB floppy to an install of VM Windows XP to allow it to read/write 720K. That's what I do all the time when I'm on my Win10 machine. And I think I had to do that with Windows 7.....can't remember.

Just make sure its that model number as there are other drive models that look just like it. Also there have been some reports that even that drive model didn't work to write 720k....however, all of mine have done just fine with 720k disks, read and write. And agreed......hardly ANYONE used that …

I bought a dozen Dell FDDM-101 drives (laptop floppy drives, but have mini-USB port on the backside as well) that can read and write (OS depending) 720K and 1.44MB. On ebay they are cheap...$7-10 shipped.
