I have bought a OPL2LPT for my IBM PC since the MCA sound cards are difficult to obtain. However it does not work. I have tried on newer systems like a later 386 with typical MultiIO card and it works fine on the LPT. Something must be different on the IBM machine, as I get only random sounds there …

I'd just use standard batteries, strictly outside of the case. The problem with that is that you would need some kind of backcurrent protection, e.g. a diode, etc., as these batteries do not want to be recharged, even a little bit. Also I found a nice place for them inside the back compartment …

I installed the 4.6GB Fujitsu HDD from my Pavilion N3350 laptop with the 2.5" to 3.5" IDE HDD kit from MicroCenter (had to buy another cable, DeoxIt, and batteries) into my Packard Bell, but it detected it as a 733MB HDD (I understand why mainly because the system only supports up to 2GB). Here're …

You are not wrong in the sense that it needs it's TSR driver loaded, or the game to be patched with the patching utility. the driver is DOS-only for now.

What about the "slowdowns" the 8bit-guy and LGR are talking about? What is the recommended CPU power required for the OPL2LPT. I own an ORANGE NUBUS PC-Card for a 68K Quadra700. This Thing has a native LPT1 breakoutcable/box but only a 486/sx25. Thx Doc According to the 8-Bit Guy's website http:// …

Quick question regarding the 3.7V Lithium TCL barrel BIOS batteries. So, the big advantage of this type of battery is obviously its longevity as they do hold (for a BIOS battery) a quite tremendous amount of current (~2000mAh). These batteries have a safety diode/aequivalent built into the battery …

I've got a new test version: http://2k38.be/adlipt/adliptx.exe It doesn't fix the problems with GLX and IPLAY (I'm not sure if they can be fixed), but it fixes problems with some Adlib detection routines that I've encountered. I've also added CPU detection code which hopefully works. If nothing bad …

Now what the TSR does is to ask the CPU to generate a fault whenever a program accesses one of the Adlib ports. EMM386 receives this fault, does some work to figure out what's happened, and passes control to my TSR. The TSR then does the equivalent I/O operation using the parallel port. This of …

I recently purchased two IIT 3C87-33 coprocessors. One is running next to a 386-SX20, and one alongside a 386-Sx16. I knew that they can run at lower speeds as they do not run in full speed (33Mhz) in either of those machines. But I didn't know that 4c87 and 3c87 were interchangeable as well 😖

In anyway, after the config.sys and autoexec.bat files have been created by your restart in msdos mode, you can safely edit these files also under DOS. Just make sure you do not touch the lines that were obviously added by windows and windows will think of these files as untinkered and even update …
