I haven't tried yet, no.

Mostly because I don't know of any good games to try.

How about.. try any Windows game that supports that resolution? 😀

But which ones? I doubt it'll even support any 3D games.

I know I tried Heroes of Might and Magic 1 as well as Curse of the Monkey Island. Both only ran in 640x480.

I don't run Windows 98 on my 430CDT. Windows 95 performs very noticeably faster and I don't lose any features I care about either (perfectly stable, usable, etc).

Anyway, under Win95 I can run games at 800x600, yes (e.g. Seven Kingdoms). I have not tried 3D games at that resolution (would run extremely slowly anyway).

Yeah, Pentium 120 is too slow for any sorts of software 3D rendering. I was wondering about 2D games. I have a 310CDT which has a Pentium 200 MMX and 64MB of RAM. It's capable of running Windows 98 perfectly fine. I'll try to do a fresh installation this week and see, if that helps at running the games in 800x600. I hate that black border that you get when running games in 640x480.

i got a 330cdt from my grandad, i used to play heretic and red alert on this back in 1998 at the time running w95, i wiped the hdd couple of years ago and found the laser unit doesnt move position, replacement drives were easy to find on ebay at the time, now nothing, any ideas for a fix? or any other laptop drives that are compatible? theres also some water damage on the left of the screen, finding a replacement might be possible.

after looking at the specs i thought DOS machine, 233mhz cpu, 64mb ram, 2mb vram, yamaha opl3, cd/floppy drive. vram being the limiting factor

I got a 430 last year as part of a lot of junk computers. I did start it up to verify it worked but haven't done anything with it yet. Surprisingly, the battery is not swollen and it did take a charge of some kind last year.
I ran games on a similar Satellite Pro with a 486DX4-100 back in the day with the same 1mb SVGA graphics, ESS/OPL3 sound, and TFT screen (I think it is a 2150CDT). It has a 500MB HDD. 8MB was standard but I am pretty sure it was upgraded to 16 (I think the 430 has 32MB installed but 16 was standard). It had 98 installed. It was nothing spectacular (about the same as a 486DX2-66 overclocked to 83MHz) but it didn't suck either. I also do not know the status of the battery in my other Toshiba but it was still working as of 2015. These things are getting to be rare enough I really don't much care if the battery works or not because I am not taking it out and about. Except for testing, I won't really use either of them.
As for gaming on the 430CDT, the first thing that springs to mind is Rollercoaster Tycoon, which I have. That's what I will be trying. you wouldn't think it but it should give the system a good workout because it just exceeds the recommended specs. It will be interesting to do a comparison where the only variable is the CPU. Since the Pentium ones even used VLB, the performance of the video chip is a constant.
EDIT: Today I fired up the 430CDT. Everything worked. I was even able to charge and use the battery! There are some minor issues - power button is missing and had to use a q-tip to press the microswitch. One of the pads on the screen for when you close it is missing. One half of the clamshell over the parallel port is missing a spring and flops around and the cover for the side I/O where you plug in the external drive is missing. There is one single, solitary dead pixel.
I installed 5 games. Super Huey II lacked sound and ran way too fast. Mig-29 would not launch and kept giving a conventional memory error message in DOS and when run in 98 DOS compatibility mode, it caused the computer to restart. Majesty Gold had difficulty playing opening video and was a bit sluggish but was playable. Originally, a P90 was specified as the minimum but Amazon sells the original version and recommends a P233 MMX as a minimum, with which I would concur, especially for network play. Roller Coaster Tycoon ran fine and Age of Empires Gold Edition ran very smoothly.
I got an RTC battery error so I will be opening it up this week.

I am planning to clone the drive in my 430CDT tomorrow onto a 4gb DOM since it is a daily driver, as well as archiving it for future use. I was going to put it into a 386 desktop but when I saw that post, I realized it would be selfish to waste it in a desktop when desktop drives are readily available. So I would be willing to sell the 1.26GB drive...
I will be doing some maintenance on it in the next few days and can get the details on the drive if you are interested.

Hey everybody, first post so bear with me if I'm doing everything wrong... There's probably a more general Toshiba thread I've missed that this might be more suitable for, but I didn't see one, so here goes.

I recently got a stack of Toshibas of a similar era - including at least one 430CDT and a couple 430CDS's, which are the same thing but with a truly dreadful DSTN screen that essentially makes games impossible. A friend of mine works with a guy who had about 15 in a shed for some reason and had asked my buddy if he wanted them. My buddy said he could get these "ancient Toshibas" but I didn't know what to expect, and while he's tech-savvy, anything prior to Windows 7 era is a foreign language to him. I've came across so many broken or crumbling XP-era Satellites that I figured that's what we had here, but then he turned up with a practically mint 430CDS and a slightly newer Tecra (the exact model of which I forget, but it was a Pentium II//Win98 machine). The Tecra was a goner, but the 430CDS fired right up and the internals hadn't leaked (I removed them anyway, of course), plus the regular battery held a good charge still. I had used a similar machine back in the day and remembered how awful the display was and indeed, time hadn't made it any better. I probably would have kept it to play with, but the terrible display and an empty wallet motivated me to just clean it up and try selling it. To my surprise, it went quick at the price of $50 on the local Facebook Marketplace (and I threw in the dead Tecra).

So expecting the rest of the pile to be the same machines, I told him to grab the rest. To my surprise, it's a whole variety of machine types ...and unfortunately, the rest are almost all missing stuff and even worse, they're all dead. I haven't torn into them yet, but most of them exhibit the same behavior - when plugged in, the battery charge light comes on but when you press the power button, you get a brief flash of green and nothing more. The Tecra from the first go-round did the same and the internal batteries had leaked everywhere on that one, so my assumption is that these others that behave similarly are also battery-leak victims - and now I've got a stack of 'em. Joy. But...

A few years back I had a hobby/side-gig of rescuing and modding OG XBOX systems. And as some of you no doubt know, the majority of those machines are susceptible to a widespread problem involving the clock capacitor, which has a tendency to blow up and potentially kill the motherboard. Indeed, nearly every system I came across had a cap that had already leaked to some degree or another, and some were bad enough that the systems didn't seem to work at all anymore, but I found that the vast majority of the time, all it took was cleaning up the mess as much as possible and usually they would work fine again afterwards. The 470CDT's board looked pretty bad, but it didn't seem nearly as awful as a couple of those XBOX'es had looked, so I decided to tear it all down and see if I could get anywhere. I usually used nothing more than alcohol, Q-tips and maybe some gentle scraping with a razor on those XBOX machines. Tonight I didn't have any alcohol at my disposal, but I was able to gently scrape off most of the corrosion and carefully "wash" the affected areas. Upon re-assembly, I plugged it in, got the expected charging lights, and when I pressed power... a flicker of green and then nothing. Bah.

So this is a long-winded way of asking, has anyone attempted to revive these after a battery disaster? If so, any tips? And failing that, if anyone needs parts, feel free to send a message... Right now my stack includes the aforementioned 470CDT, plus a 430CDS, 430CDT, 440CDT, Tecra 750DVD, and finally a 490CDXT that I'll probably keep if I manage to get it going. My buddy still has another 4 or 5 of them I haven't picked up yet so I may have even more variants!

That's going to happen to a lot of these Toshibas : ) The 750DVD is totally worth saving! It even has an integrated wavetable and DVD decoder. The corrosion of NIMH standby & CMOS batteries is somewhat different from electrolytic capacitors - Not much I can recommend other than be thorough and clean stuff up with vinegar, then clean off with water & IPA. Don't try to clear out vias as those are multi-level and basically impossible to clean. If the vias are toast, the board is toast. But good luck with them 😀 My Tecra 750DVD is essentially my favourite toshiba, nice video scaling, built in wavetable and great build quality.

Hi Gered,

I saw that you replaced your floppy and as i am in the same situation (i replaced the belt with a proper on on the original drive and it can read properly, but it cant format (says that track 0 is bad). I have the 480CDT with this external floppy, same as yours i believe.

I noticed at a brief glance that the Toshiba fdc seemed "wider" on the original drive than it does on for example my two drives (one is an YE unit and the other is a Matsushita) but they should all really be 26 pin flex cables with 1mm pitch. Is the Toshiba/Citizen "standard" like that?

Edit. Have the same issue as this poster. I checked my own and its the same proprietary connector unfortunately 🙁

Anyone know about old laptop floppy drives?

Gered, hi! Any chance you have factory restore disks for this laptop? Just bought it and soon I'll start digging inside. Wanna try original vision of the system. Thanks!

I do not! That would be neat to have though ...

You've probably found this via searching around already, but just in case you've not, you can find the original drivers and such for the 430CDT here: https://support.dynabook.com/support/modelHom … 67&osId=3333621 .
