It turned out to be a Soviet clock, alarm clock, and calendar. True, they're not exactly in mint condition; the inscriptions are gone, and the stand's feet are missing. But the screen still shows the time. And yes, the LCD screen quality has deteriorated over time; it's only visible from certain angles.
Before replacing the system, I had to first drain the remaining bad oil, then flush it twice with isopropyl alcohol, then thoroughly blow out the system with air to ensure no alcohol remained. Finally, I filled the container with 1 liter of this fluid and pumped it through the tube until MQL appeared in the nozzles. Could you please tell me from experience, is this fluid suitable for machining aluminum, and what should I pay attention to when setting up the MQL system?
It worked! No pain or wasted time. I simply installed a graphics card with 8MB of memory and everything worked! Thanks so much for your help!
I tried running it with the code, but so far it's just junk. And the first part of the screen won't light up. I showed a photo of what I was able to achieve. Perhaps someone has encountered such screens before and knows how to set them up correctly.
I saw it once, though it was almost completely disassembled, rotting in a field. The machine itself is simply magnificent! A ton of hydraulics, automatic controls, and it all obeyed a single algorithm! What a shame I never experienced these joys myself. All I have is this CD and a floppy disk with the program for controlling the cabin hydraulics.
Doron Precision Systems, Inc.
They specialize in the production of driver training simulators.
Their products include simulators for training truck, fire truck, and ambulance drivers.
The company's office is located in Binghamton, New York, USA.
These arcade machines are called Motion Simulator Capsules. Doron Precision Systems revolutionized this industry with the release of the legendary Doron SR2 ride in 1977.
Features of these rides:
Capsule cabin: A completely enclosed futuristic enclosure that isolated players from the outside noise of an amusement park or shopping mall.
Moving hydraulic platform: The seats inside the cabin moved, tilted, and vibrated in sync with the action on the screen. This created the complete illusion of G-forces.

Capacity: Depending on the model (for example, the popular Doron SR2, SRV, and Transport 6 series), the cabin could accommodate anywhere from 4 to 12-15 people at a time.

Large Screen: Inside, there was a projection screen that displayed the pilot's or driver's perspective.

Most Popular Simulator Themes:
Roller Coaster — the most popular simulator, fully replicating the wild drops and loops.
Flying a fighter jet or space shuttle — with slopes, loops, and simulated aerial combat.
Off-road or mine racing — minecarts speeding along old rails with sharp drops and turns.
Similar devices were installed at the entrances to large amusement parks, in arcade areas, and also in Soviet amusement parks in the 1990s (often imported from foreign tent amusement parks).

Artifacts have appeared. Since I removed 1 MB chips from another board and inserted them into the sockets, it's likely that there's simply no good contact. Tomorrow I'll try to desolder the sockets and solder the memory chips directly onto the board.
I need your help! I need to figure out if I can remove the memory from any other video card to upgrade it to the S3 ViRGE/DX S3 86C375 ViRGE/DX.
It currently only has 2MB, which isn't enough to set the desired resolution at the desired bit depth. The Reddit system determines either the resolution or the color depth. Anyone with any ideas or suggestions, please let me know. I welcome any comments or suggestions.
Hardware:
Single-board computer IEI/ICP ROCKY-3786EV-R11 (Ver 1.2) on a PICMG-14S3 backplane — used as the control system for a CNC machine
Chipset: Intel 815 (integrated graphics, Intel 82815 Graphics Controller)
BIOS: Phoenix-AwardBIOS v6.00PG, board BIOS version V1.3 (2003)
OS: Windows 2000
Old monitor: CRT (removed, will call it "original")
New monitor: Fujitsu B19-7 LED, supports 1280×1024
The problem:
With the old (original, CRT) monitor, the system happily allowed selecting 1024×768. With the new Fujitsu B19-7 LED connected, the maximum available in display settings is always 800×600, regardless of which monitor driver is installed.
What I've already checked and ruled out:
Graphics driver — updated from 6.13.01.3004 to the final official version 6.13.01.3196 (the last one Intel ever released for the 810/815 chipset). Problem persisted.
Monitor driver — tried: the native Fujitsu .inf (Windows 7/8 WHQL, won't install on Win2000, Code 31 error), the standard Windows "Super-VGA 1280x1024" profile, the "Digital Flat Panel (1280x1024)" profile — in every case the resolution slider caps at 800×600 specifically with the Fujitsu monitor connected.
VGA cable — replaced with a new one, no change.
BIOS — board BIOS is up to date (V1.3, newer than anything I could find in public archives), On-Chip VGA is enabled, nothing resembling a resolution limit setting exists there.
Direct test — connecting the old CRT monitor expands the resolution list to 1024×768 without issue → so the graphics chip is physically capable of more; the problem is specifically in the "Intel 82815 ↔ EDID/DDC handshake with the Fujitsu B19-7" pairing.
My hypothesis: the issue is incorrect EDID reading over analog VGA/DDC2B between a very old video controller (year 2000) and the modern electronics of the LCD monitor (manufactured 2013).
Tried as a workaround: found an old PCI graphics card, S3 Trio3D/2X (86C368), to replace the onboard graphics — but it physically won't seat in the backplane's PCI slots, likely a voltage keying mismatch (5V vs 3.3V/Universal PCI).
Question for the community:
Are there known ways to work around EDID reading issues on old Intel 810/815 chipsets with modern LCD monitors (e.g., forcing a custom EDID/INF without a live monitor poll)?
Is it worth trying an active VGA→DVI/HDMI converter, and does anyone have experience confirming this actually helps in cases like this?
Has anyone run into this exact combination (old Intel 8xx chipset + modern LCD monitor) and found a working fix?
I'm wondering what interesting thing I could do with them?
I still didn't buy the calculator because it had a partially working screen and no back cover for the battery compartment.
This interesting specimen was found at a flea market.
I want to understand if the tool change is working correctly. It seems to me that the chuck is pushing the feed plate too far.
I couldn't buy it, though, as the seller was asking too much for it, but I did get a photo of it.
The tool changer for the HSK63-f chuck is acting strangely. Sometimes it simply opens the collet and the ejector gently nudges it to release the chuck, but more often than not, it simply ejects it! What I did: carefully cleaned the inside with isopropyl alcohol, dried it with a paper towel, and lubricated it. But the ejection effect persisted. It was there from the very beginning, when I bought the machine; I just hadn't used the automatic tool changer until now. Now it's time to adjust it, and I noticed this behavior. Incidentally, one of the 10 HSK63-f chucks ejects only a little. I noticed that when clamping the tool, the ejector reaches the bottom of the chuck, resulting in a 0.9mm overhang from the spindle flange to the chuck. This ejector likely ejects it before the collet releases it. I'll attach a few photos with the changes. Please ignore the fact that the photos are sometimes taken with the tool positioned poorly for measuring. It's just hard to measure and take pictures with one hand. I don't know why, but I couldn't attach an additional video to this post.
To this day, fragments of a once great empire can be found at Sunday flea markets.
Although my HSD ES-325 spindle is factory-configured for liquid cooling, it was likely reconfigured for air cooling for font work. Luckily, out of curiosity, without a schematic, I started tinkering with the pneumatics. It turned out the pressure regulator was missing an adjustment screw, meaning I wasn't getting any air for cooling. Since the original screw wasn't in the machine, I found a suitable one and adjusted the pressure to 4 atmospheres, according to the manual! Hooray! Cooling started working! But you know what I was thinking? I still want to install water cooling! Can anyone recommend this system? Although I'm familiar with HVAC. I'm more concerned about whether the fluid might accidentally leak into the motor cavity. I think this is because there are NBR seals in there, and with age, they tend to dry out and shrink.
I ordered the clock board on AliExpress. The clock has such a gorgeous lamp; any lamp lover should have one!
Currently, I'm using a single-cutting-edge aluminum milling cutter with a DLC coating. I tried to keep the feed rate and the cutting depth low. If I've made any mistakes, please help me figure it out! I'd appreciate your expert comments.
