My Army has Grown Six Strong since 2019.......with some updates for what I have......starting with the 486s because size limits (I have 5 486s, one Pentium)....

SOUND: Internal Speaker Only (Bleeper)
NETWORK: None, Planning to Get one of those Serial Modem/WiFi Cards and maybe a OPL3LPT for it
O/S:MS-DOS 6.22 and Windows 3.1
I bought this Computer off E-bay earlier this year for a bit of a crazy amount considering it was untested. It seems to have belonged originally to a Chinese power plant engineer or something like that. Had a lot of personal documents and whatnot to wipe off the Hard Drive. Has a few games. Has the original DOS and Windows Hotkey Utility Programs on it. I've really tuned this thing up. Runs pretty well for a DX-33, though I wish I could toss something faster in it eventually and maybe some more RAM. RIght now I'm running the stock HDD because I'm not sure how a SATA or SSD drive will handle in this machine yet, but it looks promising since it's pretty forgiving about HDD Settings. The BIOS Is an Award/Phoenixview BIOS similar to the old Zeos motherboard I had on my first 486 Desktop a milion years ago. It also has the weird trackball option on it. The battery did work for about 30 minutes when I originally got it but as of late won't take a charge - might have shocked it too hard with the charger. But the laptop does work and for gaming it's actually a fun laptop for things like Duke Nukem, Tank Wars, and other things that use the internal speaker. It needs a replacement for the leaked out Varta Battery I removed though. Future plans include adding a RS232 Serial WiFi modem and possibly an OPL3LPT to it to enhance it's capabilities since it has a surprisingly ghost free and quality looking DSTN LCD on it.....it's very crisp and with some alignment of the layers would probably come within 30% of my NEC's TFTs.

I bought this because I used to have a Duracom 5110D DSTN Laptop that was very similar (and a Prostar 9200M before that that's almost identical). This laptop is 25MHz bus though so the DX2-66 is probably running at 50MHz- underclocked. It originally had a 486 SX-25 CPU in it (still have it, working pull). Still pretty zippy. Moved all the original HDD contents to the 2.5" ATA-133 drive it has now so it could have the original utilities for handling APM, LCD, etc. I'm toying with snagging some kind of Active Matrix or DSTN LCD panel and upgrading this. It looks like it may even be possible to use an NEC NL6448AC30 series panel in it (that would rock). The trackball is pretty good, the keyboard is an acquired taste (a bit mushy for some people), and it does really good on WiFi. The LCD Panel is "meh" - it's a Casio, I don't expect it to be all that impressive, but it actually looks pretty good for as cheap as it is. I plan to put a WiFi Card in this one eventually as a permanant one so I can stop passing around the same two Aironet LCM-352s between all my laptops that have PCMCIA. It has a pretty cool startup chime. Either way, I'm keeping it even if the screen is not what I want for now, since I think it could become a real screamin MS-DOS gaming rig someday. It actually would do decent for on-the-go-MIDI Composition though. I had a guy on YouTube message me about sending me an Active Matrix LCD panel setup from one of these but I never got a reply back. That would have been cool. He said the LCD was an NEC, if so I wonder if it's the NL6448AC30-12 model because I see a lot of those going for a fair price these days compared to the other models my NECs use.

O/S: MS-DOS 7.01, Windows For Workgroups 3.11
This is the one I've had the longest. I bought it in mid 2019. I started going back toward MS-DOS when I found FreeDOS would not play ball with certain games right and exhibited odd behaviors on others (particularly on games that use the VooDoo memory Manager from Origin Systems). It has no sound, though I do have a Panasonic D20 SCSI/Sound card that would work on it but I'm still working out the audio connector pins on that card (have been unable to download the service manual though I see it available in some places). It has a marble contact-PVC backing on it to cover up the original early JB Weld and Baking Soda/Superglue repairs I did on it. I still bring it out from time to time, but I need to tighten the hinge I loosened up (I find loosening the friction clip a hair and then slightly jamming the friction pads inside helps make it just right). The entire undercarriage has hairline cracks reinforced with the BS/SG mix process and they are holding up great. This one I've done the most electronic repairs to, and as it's so finicky, I tend to be careful what I use it for, even if parts are still availible with it (lots of early experiments with batteries and sound and so on), but I also have learned the circuitry really well on this machine so I'm ready for a lot of board level repairs with it. Performance seems more like a DX2-66 than a DX2-40.

NETWORK: Same cards as 40EC
O/S: MS-DOS 7.01/Windows 95 OSR 2.5/Windows For Workgroups 3.11
This one is my main of the laptops for most things, it has a bright, crisp screen (though letterboxed), responsive, smooth trackball, it's basically a frankenstein NEC of a model that never existed (as far as I'm aware NEC never made an 800x600 Pen/Touch portable 486) - so the model designation is my own - HCP - for HIgh Resolution Color Pen/Touch Display. It's fast, it's mean, it has the Words + System 2000 AAC Unit under it which I use for vocals on BandLab sometimes (albeit mostly funny/goofey stuff for fun). I had to get a new casing for it from a dead M/75TC because the original case cracked apart so bad. I run this one very hard and it's the one I'm using the majority of the time. It also has Executor on it so I can run some Macintosh applications as well (hehehehe, mini 68040 portable, 🤣). All I need to do to finish it is get a LCD glass module for it, I think it was something like 238mmx178mm (10.4" glass w/ 9.5" active area - 3M MicroTouch - 63-4631-00-01 Cleartek I Digitizer, 5-wire - I found some documents on 3M MicroTouch to help me figure out more of what I've got. I've been seeing some expensive examples on e-bay but I'm going to jump for it if I find the right one, then likely rewire one of the RJ-45 pens for 1/8 Phono once I do my usual BS/SG/JB reinforcement jobs on the screen hinge and attachment areas. Would be fun to use Graf-X II as a drawing tablet on this thing, or play Hoyle Classic Card Games with my finger.

O/S: FreeDOS 1.2
This was the last Versa I bought, I think early last year. It's a darn near mint example in a lot of ways with very few repairs. Even the screen is still original on it. It was bought barebones. I did have to do one electronic repair when a HDD bit the dust and blew a fuse in the power section - right now it's jumpered with a thin wire, but will likely be replaced eventually with a proper fuse (I have a photo of it). It's one of my earliest SMD Soldering Jobs. This one is the FreeDOS machine now (for the most part). So I use it as FreeDOS beast mostly. This one is probably my second favorite because it's such a bloody trooper and very no-frills, so it just keeps on working no matter what you throw at it. Runs about the same as the 40EC, just a hair faster. Probably my favorite one for older MS-DOS games besides the BSI.
All of these save for the BSI have their HDD arranged the same way....
OS = Drive C:\
APPS (except Internet and DOS Shells + Executor) = Drive D:\
GAMES = Drive E:\
RESOURCES = Drive F:\ - this is where all the ISO Files go
Currently as my VersaDock is still broken (bad PSU, need to replace 2 caps in it), I'm using my Desktop 486 to rip CD-ROM's to the laptops, or I'm downloading ISO files directly using Cell Phone Tether (not that slow, downloaded all 620MB of an ISO once in a couple hours when I had nothing better going on). I then use the SHSUCDX utilities to mount them as virutal CD-ROM drives and then use them when needed with certain games. This is a big reason why I have ginormous hard disks in most of my vintage computers, is because I want the resources to be there and I don't have to go digging around for some flaky 10-20-30 year old CD that may or may not have issues. Sometimes I just put the hard disk into my 486 desktop and do all the file moving there as that has a fast DVD-RW drive (to use with OMI, never lets me down), and plays well with FTP (mTCP x FileZilla on my Mac or Linux boxes).
Most of my installs are about 3-4 years old, in the case of the BSI, it's the original install the owner did back in 1992-1994ish likely. I'm trying to kind of hone down the size of my installs in some cases so that I'm not constantly moving files around (irritates my wife). At this point I'm starting to treat them more like a rich guy would his car collection - parking them out to look niice, as sort of ambassadors of computer history with a little more power than usual.
