Awesome, really glad to hear it @InbetweenDays! I'm curious how your recreation of the -22V PSU goes as that's a weak point of my setup (or any of these) as far as bizarre, unique parts goes.

I do, it's the decimal key on my numeric keypad on the right, and the INS key is the zero.

It's not super playable except at a tiny viewport size, since this is a 16MHz / 8MB RAM / 256K VRAM machine, but it was fun to launch. I have a 2000-era P3 that is just fine if I want to get my fix. I'm mostly using the 386 right now for experimenting with MS-DOS, serial comms, CGA games, custom …

Correct, no docs for the Cirrus Logic drivers mentioned by Jonas-fr above. I recently obtained this 386 luggable and although it has paper manuals for the motherboard and peripherals, there is nothing about the CL card except for some penciled-in DIP switch settings and two 3.5” and one 5.25” floppy …

Sure thing, here is EAGLE.COM, SWITCH.COM, and a third one called VSCREEN.COM that I think is related but only indicates that it's already loaded when run after the first two. I'm not sure of the versions offhand.

Thanks for the link. I got my machine to work in standard ways with DOS & Windows as well as a single-floppy Linux from 2002 and there is no sign of this problem. So far, it's been limited to when the VGA card was in my more modern Pentium III system's ISA slot trying to run various systems.

I got my machine to work, so this is on hold as I don't need any sort of ISA-capable emulation now.

I did eventually get my card (and whole machine) to work, so I've now got a great reference version of an LCD-386 should you need any details. https://www.vogons.org/viewtopic.php?p=857849#p857849 The machine came with floppies containing EAGLE.EXE and SWITCH.EXE which allow for console, GUI, or …

Miraculously, I managed to repair and boot this sucker! It was indeed bad traces. I identified two that didn't have continuity and repaired them. traces.jpg repair.jpg I was then able to piecemeal test all the RAM, all the way back up to the 36 DIPs and 4 SIMMs at 8MB. Reassembled everything and it …

Over in this post I have a weird old VGA card with custom ribbon connector to an LCD working finally, transplanted into a modern(ish) machine but powered off of the original PSU. The card has 8 DIP switches on it that allow you to specify (among other things) what graphics mode it runs in... I have …

I've confirmed that the VGA card and LCD are working properly by: - Putting the VGA card in a working ATX machine & connecting the LCD - Powering the LCD bus on the VGA card from its original AT power supply, which has special connections for +12V and -22V - Tying the ATX & AT power supply grounds …

Old thread, I know, but I have acquired a similar machine (see my other posts) and am in the process of debugging the motherboard, which can't even POST. In between bouts of frustration with that, I am attempting to get the VGA card going in my other PC, which is ATX but has one ISA slot. No luck so …

That's helpful, thanks. I'm thinking of trying a 386 motherboard just to see how this video card and LCD perform, but figured I might try to make an informed purchase of one I could possibly fit in the case if everything ended up working ok (haha).

I have a Dolch-esque 386-LCD clone that I'm attempting to resurrect over in this post . At this point, I'm pretty much down to the guess that some of the motherboard traces have been damaged by the battery leak. I'm going to attempt to repair them (I think?) but assuming that goes badly or doesn't …

I have not. I don't have access to any just yet; this is my only vintage machine. I did try removing the 4 SIMMs (to try the 36 DIPs), then removing the second bank of 18 DIPs, then removing all the DIPs and trying each combination of two of the 4 SIMMs. I set the six corresponding jumpers …

I've acquired a late-80s portable 386 with builtin LCD in unknown working state. It only ever beeps continuously on boot, with no picture on either the built-in LCD or an external VGA-connected monitor. It's not a series of beeps, but one, long, very loud beep forever. Relevant details: 386SX-16, …
