Looks more like an XT class (with the V30 on the motherboard) with a 386 upgrade board (the 386 being added on top of the MoBo). Not a regular 386 with an added V30 :) Nice, whichever way you look at it :) More like PC-9801VM class in this case (except it's technically a VX+ given that it has the …

Got this in the mail last week and fixed it. It's a NEC PC-9801es. It's just a normal 386...except it has a V30 too and can run classic point and click adventure games like Yu-No. Luckily it still works despite battery leakage and I had to build a homemade PSU adapter. I mainly bought this to drive …

The most compatible extender I found was dpmi.exe as included in NEC MS-DOS 6.22. the other extenders appeared to work but didn't support the dpmi calls that djgpp used when the code actually was loaded at runtime - at least those I use to allocate the far pointers and segments needed to map the …

That's really useful, thanks. My main targets will probably be a MPU midi output (and I see there's a driver linked on of those pages above for the Roland type midi interfaces), as well as FM playback of midi files and simple 1 voice pcm (lowest common denominator for almost all the platforms). A …

What I have struggled to find is anything on the sound hardware. I'm writing an RPG engine and I'd like to target the PC98 (alongside Dos, SDL, Sharp X68000 and MSX2) but at present I can't find any details on sound APIs for it. A lot of PC-98 games used two sound drivers: FMP and PMD. Other games …

Mine came with an S3 928 powered windows accelerator C-Bus card (which Ive never used as it wa always intended to be a DOS/programming toy and I've since added a SCSI controller (with the aforementioned Exide rom) as well a Roland MPU401 card. I do most of my development using djgpp under Dosbox …

This thing sounds like a minefield of headaches to maintain. Glad you were able to avoid failing caps and burning out the motherboard. How wide of a range of games are you able to play on it? Most of the games from the era work on it, I mostly set this up for games that need the YM2608b. It's also …

Bought this a few months back. It took a long time to arrive and it took a long time for me to get time to know the insides of it :) Nice machine, but you might want a nicer PC-9801 machine for those Window Accelerators (since they're for Windows and a few 256 color games). To use them you'll need …

So here's the thing, for the past year or so I've gotten back into PC-98 collecting. I originally dabbled with it in the mid-2010s with a Ce2 and later a V16 (which didn't have a sound card) and I never exactly had money to spend on it. Unfortunately I wound up getting money from a job. I first …

Nice, I got a Pentium Pro again recently (My Vectra VA 's PSU died :( ) but it's something even weirder, a Pentium Pro DOS (not PC) compatible; the NEC PC-9821Ra. It has it's own port of Windows, NT, OS/2 and DOS as well. It has an i440FX chipset and uses EDO Parity SIMMs. It runs games, but not the …

The first question is, why would you want to run a Voodoo5 on a dual-core system? Chances are an integrated GPU or cheap PCIe/AGP GPU from that time period is going to destroy the Voodoo5 in anything, along with a Glide wrapper. Now if you want a system that can drive it, go grab a random old Socket …

Here's a glimpse of my basement. From left to right, IBM Intellistation Power 275, SGI Octane (xbow 1.4), HP ZX6000, HP 9000 425t, empty eATX case I'm going to build a system in, NEC PC-9821 V16, HP 9000 380. Filename photo_2019-05-03_10-43-05.jpg File size 162.33 KiB Views 2007 views

I always wanted one of those. Had one in past at work running WinNT3.5.1. Great workstations. That’s twice the performance of my AMD 5x86-133-P75 computer running Win95c. With 64mb 60ns EDO ram. But I am using a 8gb. CF card for a boot drive. I would get a color correct HP 4x IDE CDROM and floppy. …

Since this is the place where everyone shows off their sick retro DOS computers, I'd like to introduce mine: a HP Vectra VA desktop with a Pentium Pro 200, Matrox Millennium, and a SB16 value. IMG_20190502_172613.jpg Right now you're looking at this thing thinking it's like every other computer, and …
