Interesting case. Looks like a full height version of the low-profile cases I have (the two on the left). At least, they seem to share a very similar design language. The one on the left is my 286/16 and the other is my 386DX40

Did some experimenting with a Paradise Basic EGA card on a Compaq Portable 1 system using the internal monitor.

It's not perfect in every way, especially the picture doesn't look well on the internal monitor since it's an analog display (also TTL supported), but the picture quality using the MCE2VGA and VGA2USB via OBS is crisp.

Gotta do more adjustments or look for a Compaq EGA card that has an internal display header.

Also swapped the floppy card with an XT-FDC + serial card and flashed a modded BIOS to see the LPT port with the address 378h.

Gotta 3D print some custom expansion card brackets for both the EGA card and XT-FDC so they can be screwed in without having issues getting loose.

I'm just about to finalize my XP/Vista dual boot build.
I added the CMR-225 docking bay and a 320GB Hitachi hard drive of my dead then reanimated then dead again G565G laptop I used during college.
The XP SP3 installation I had on it didn't really care. Booted up without any issue and after installend the drivers, it seems to run. The only thing is that it seems Metropolis Launcer now crashes.
Also I had 2×1GB Kingmax DDR2-800 and 2×1GB Hynix and it seems one of the Hynix sticks failed for some reason. I wanted to replace them with identical Kingmax anyway.

The Gainward 8800GT to replace the 8800 Ultra is on it's way, I expect it to arrive some time next week.
I'll also planning to pick up a 1TB hard drive so I can free my 500GB 7200RPM HGST drive an use that for Vista.

Until then, with some of the stuff I had installed, I tried if the Intel X3500 graphics accelerator is as bad as he X3100.
Quake 3 Arena (GoG) timedemo 130fps
Half-Life 2 (retail with Vengeance crack) prologue around 30-35fps in open areas and around 45-65fps inside.
Both in 1024×768 high.

Prepped 2 Tualatin boards for incoming processors. Cleaned them up and flashed latest available BIOS.
One is Intel D815EEA2/D815EPEA2 and other is Epox EP-3PTA. Epox had about 10 caps replaced.

Are you sure that D815EEA2/D815EPEA2 can run Tualatin cpus?

My heart felt warmth 😀
That is beautiful. I wish I had some nice case like those.

Playing musical chairs with resources for my triple sound card build. Three cards normally isn't too bad, but these are a bunch of resource hogs, two are PnP and one of those isn't supported by Unisound and had its own crap utility that tends to hang the system if it can't allocate the resources it wants.

Star players:
- GUS (very much the non-troublesome of the three)
- AWE64 Gold (well, if we're going for ultimate late DOS build why not?)
- Terratec EWS64XL. This is the one with the nasty config util.

If i disable the second (external) MIDI on the EWS64XL I can get it all working together - until *any* other (PCI) PnP card does anything different, then it all hangs again and I can only recover by removing the AWE64, booting to get the EWS64 behaving, then shutting down and inserting the AWE64 again... of course I actually *do* want the external MIDI on the EWS64 to work, and this crap involving physically removing the AWE gets tiring, so I'm tempted to just replace the AWE64 with a non-PnP SB16. Too bad about missing the AWE, but I never really liked it that much anyway. Downside is that that does give me SC DMA clicking. Maybe I can convince myself to take another shot tomorrow.

There were several indications that this case is from 3rd quarter 1991, up to and including a sticker on the P/S that said Oct 1991. 😉 Original Seasonic power supply too (not a size I've seen before - width/length is the same as a standard AT/ATX, but about 2 inches of height added, as well as a physical switch out back) - I would not be surprised if these cases housed later 286 16-25 MHz systems in their product run.

Definitely a well-built case - heavy, well machined, good use of plastics, and sturdy design.

I think you can disable all AWE related resources, which would give you the equivalent of a very expensive SB16, but might work around your issue . You probably would want to try UniSound for the AWE64, if you are not already using it .

Best of luck!

I spent half the day putting 400 KM on my car (which is a rarity, since I purchased in Oct 2020, my family put 3,000 KM on it) getting all sorts of retro gear. I scoured several thrift shops along the way and met up with two sellers. I got:

-8 USB (PS/2 compatible) original Microsoft optical mice
-Some PS/2 keyboards
-Three 4:3 LCD monitors
-SCSI 68 pin to 50 pin wiring (external) - not really needed but for $4 I'll take it.
-SCSI 50 pin internal wiring (for the NEC V30 JUKO - It's going to get an SCSI CDROM!)
-TSENG 4000 1 Mb VESA card (which emits very dim text - I'll troubleshoot that later)
-An XT Compaq Deskpro keyboard (paid a good amount, it will also need retrobriting) for the same JUKO V30
-A 256k cache module for a Socket 7 motherboard. I grew sad at the fact that it was pulled from a motherboard that likely went to the recyclers.... Along with the case it was in 🙁
-Speakers. Every set of 90s speakers I could find in the thrift stores along the way. Most will be set up with eBay computers, but I have a comically large AWE speakers. I'm not sure what I will do with those.

It was tested/flashed with Tualatin Celeron 1100 😉.
But yes, there were 2 versions of this board and the first one did not support Tualatin chips:
* D815EEA/D815EPEA
* D815EEA2/D815EPEA2

The problem isn't the resources as such (A240 I7 D H5 P300 E620 T6 works fine, using IRQ 10 for the MIDI, with the EWS64 on A220 I5 D0+1 P330 and IRQ 2/9 for MIDI and GUS on A260 I3+3 D6+6; I've disabled LPT and COM2 and shoehorned PCI stuff into IRQ 11-15), it's the PnP process. I've tried both CTCU/CTCM and Unisound, but it doesn't make any dfference; the AWE64 behaves itself. It's the EWSINIT.EXE that hangs if it doesn't like what it's seeing. One thing left to play with is order of initialization.

Granted I don't have a gus, but I do run a ews64xl and a PNP awe32 together. I initialise the Awe with unisound and the EWS is first configured with the eeprom util (ran in command line safe) and then just init the card afterward. It's been a while now, but I didn't think you needed to assign a IRQ to the midi2. you could just select the address and leave the irq as --. I may be wrong as its been a while. I can fire the machine up and take a look at some point.

I feel your pain with resources. I tried to get a Aztec card to play with my Awe64 gold the and I had to give in the end to save my sanity! They just didn't want to work together.

Fixed my whining Sharp X68000 power supply:

Upping the filter caps from the newly replaced 5600uF rated parts (every cap had been replaced by the seller, to original specs) to 6800uF components, along with a new Noctua fan has made it absolutely silent. So, the 'scene' recommendation of increasing the capacitance of those two parts was spot on.

I am very, very happy.

Nice work and good info to know!

I am so pleased. This has been almost a 12 month journey to get a system to the point where it actually works. Now it's a case of adding all of the juicy add-ons I've collected over the last year; MIDI card, RAM expansion, SCSI2SD, external SCSI Zip drive ... and then start putting games on it.

I've already tested it via Gradius II booting from a couple of 5.25" floppies, and oh my word; it is simply amazing. The only thing that comes close to replicating the experience of 'it looks and plays exactly the same as the arcade' is the NeoGeo.... but that's not also a fully-fledged computer.

I've played lots of games via emulator, as well as done a significant amount of coding for it (using C I wrote the same game browser/launcher I'm in the midst of doing for DOS), but using the physical machine is a different experience entirely.

Filled a gap.
Don't like gaps.
Well not this one. 😉

WTF... i387?

First time I hear this

EDIT: Facepalm... of course... coprocessors. Had to ask my old parents about this...

Today I recorded a few more tracks using my Guillemot Maxi Sound Fortissimo. Really loving the digital out on that card. It also has a bugfree MPU-401 interface, so I'm using it to push MIDI to my Roland SC-155 as well. Latest recordings:

• Cybersphere - Stage complete (OPL3)
• Doom - E1M8 (Roland SC-155)

I picked Cybersphere because it's one of the few games that make full use of the OPL3 chip. And I chose Doom's E1M8 (Sign of Evil) because it sounds great on a Roland Sound Canvas.
