I use an eeprom programmer, like FaSMaN. But sometimes when the flash chip is soldered or too tiny, I do boot from flash media. Be it an USB pen drive or a CF card.. And I also have some floppies in my drawer in case this doesn't work.

Why using a power converter when you can built your own psu ? A good ol' 7805CV and 7812CV should be sufficient for that task. They have a thermal overload protection and are quite durable. Just wire them up to some adequate transformer and you're ready to go.

1) The internal mount command in DOSBox is done via its emulated DOS. Once you boot off from an image, it is gone. 2) DOSBox can handle every joystick or gamepad available to the host OS. It then is accessible as a virtual joystick on an emulated gameport. This means that you're restricted to say a …
Re: How different is Windows 9x from NT? Are they not the same?
Posted on 2016-05-14, 00:07
I don't see any reason for NT. On Windows 3.x you can run a lot of games. Most of them run the same on Windows 9x BUT you can run Windows 3.x in Dosbox eithout any problem ;) Errr... there are a vast world outside games, you know. The question I replied to was what people are using NT or Windows …

I upgraded my Pentium 166 MMX from 24MB to 64Mb just for XP! Are you sure you aren't mistaking XP for Windows 2000? Windows NT real life minimum was 32MB. For W2K it was 64MB and XP was more like 128MB. It would run on less but at what "cost". Yup, it was XP, running at the bare minimum …

It's also important to note, that while the Win32 API was made for NT, Win32s on Windows 3.1 was the first implementation available to the public. This is quite interesting, as some early programs can run on Win 3.1 just fine, but refuse to run on Win NT 3.1. Even more, there were -at least in …
Re: Debian dropping support for pre-i686 class x86 CPUs
Posted on 2016-05-12, 20:37
I wonder, is the lower limit for i686 anyhow related to it's ability to do 36 bit adressing ? That's the only interesting feature, I can think of and the i586 can't do that.
Re: Gotek emulator woes
Posted on 2016-05-12, 19:21
Yeah, that's indeed a good idea! This should work well with DOS style floppies. And if the disks are in another format, there's still hope. I know of an old copy utility, QCopy, which had the ability to reformat the floppy format on-the-fly.
Re: Broken PAS Plus - Last ditch attempt to repair
Posted on 2016-05-12, 16:44
I'm not sure, but it seems something is oscillating/ causing a reaction coupling. The MIC cable maybe then works as some kind of anntenna or is acting as a capacity/inductivity. At least this would explain interference on the display. Well, kinda. Audio circuits with missing blocking caps act …
Re: Gotek emulator woes
Posted on 2016-05-11, 17:53
Wow, that's some kind of question you don't see every day! I'm no owner of a Gotek emulator myself, but I have an idea. You can try to open those images (*.img or *.ima) with WinImage and then change the floppy format. But becareful, this can render the image useless in some cases. So better make …
Re: What's this video connector? (COSMAC VIP)
Posted on 2016-05-10, 14:37
Yes, I think so. I don't know for sure, but it really looks like a connector from the amateur radio scene. It's appearance is similar to that of the plug for SO-239 socket (PL 259 or UHF connector), I think. They were quite popular back then and are still used for antennas and such.
Re: Abit PB4 (486), ISA sound card - OK in DOS, not detected in Windows

Many of my dads EPROMs are from the 70s and require a voltage of 21v to 24v for programming. A few of them are so old, that they need a long time exposure of UV light until they are erased.

Sorry, I thought Me had similar limitations because it is/was an OS from the 9x line. I heard it somehow got improvements from the Win2000 TCP/IP stack, but I don't know any details about that, except that it got Univeral Plug'n'Play. Still, I wouldn't call it a pointless test. I had the same issues …
Re: Need some help with installing CDrom drivers without floppy :(
Posted on 2016-05-09, 12:29
Can you access the PC-Card slot from DOS ? Sometimes the needed drivers are loaded before Win95 starts. If not, maybe your ThinkPad can boot from it. Then all you need is a CF card and an adapter.

Hi, I think it would help, but only to some extend. A recap can't fix a flawed audio circuit. (-> noise from the ISA bus). To fix this, you'd have to modify the circuit and add some kind of blocking capacitors or choke coils. In my opinion a recap is nevertheless a good idea. If you're skilled with …

Hello, just some small feedback.. I got it working in VirtualBox. I was able to access a folder located on my Win7 computer. I used two VMs, Windows Millennium and Windows 7. Some things worth mentioning I did: a) I added a registry entry in Me. In "HKLM\System\CurrentControlSet\Control", I created …
Re: 3 floppy drives
Posted on 2016-05-05, 15:43
The plan is having those 3 drives on a Pentium II or as early as 486 and have Windows 95C. The first link above me claims I should look for a 4-drive floppy controller. So I guess i'll be using an early 486 that takes I/O add on ISA cards. Since I don't want to disable the onboard floppy. Would …

Sorry, haven't thought of that. Now you're saying it, I remember old AGP devices were quite troublesome. @markot You're right, it's a transistor (a MOSFET). They're pretty much tough, so maybe the cause is something different.
