At first I was also skeptical about these SDCARD converters as I have more than enough of old IDE drives I got for free/as junk however they have 1 huge advantage they are completely silent and don't generate any heat either. Now my retro build is completely fanless except the power supply... …

Re: Incorporate custom SYSEX into MIDI playlist, for changing MT32-pi soundfonts between tracks

In your setup you'll probably want different MIDI files to perform each switch. You can't pass a parameter to the file so each like you had in your example you'll have one that does switch to soundfont 0, soundfont 1, etc. Another thing to consider is that it will take at least a second or two for …

Thanks Megatron, yes these are labelled as THRU ports on the MindBurner. It does make sense totally to swap the UM-ONE to use the 'OUT' port, I'm just going off what I've read on the instructions and it indicates the IN cable should go to the IN on (for example) the back of a Sound Module... Check …

I forget if it's in Win98, but if you right-click the executable and select properties. On the compatibility tab is there an option to set 256 colors? This exists as far back as at least XP.

GOG has the singular advantage of being legitimate. As I said, linking to abandonware sites is frowned upon here. (I would have doubts about whether REMOVED is necessarily a high-quality archive, but I can't say I've seen it myself.) REMOVED isn't really a preservation archive, but it's thousands …

I expect it ought to be possible to make an xdiff file patch between the GOG version and the older version, and thus avoid having to link to abandonware websites (which tends to be frowned upon) – assuming it's not just a matter of adjusting a preference somewhere. The issue is the GOG version is …

You can and it has nothing to do with any soundcard unless you are piping the MT-32's output back into a link in on a PC to do mixing there rather than an external mixer. Some people might find extremely minor differences, but with how much a real MT-32 costs there's not really any reason to use one …

The Falcosoft MIDI Player has OPL3 GM emulator VSTi which includes source. I believe the OPL3 implementation is based on DOSBOX OPL2/3 and Nuked OPL3 implementations. https://www.vogons.org/viewtopic.php?f=5&t=48207 There's also FMMIDI which plays MIDI files on an emulated Yamaha YM2608 (OPNA). …

WazMeister wrote on 2021-03-18, 22:39: Right, it says 128kb now.. Is that right? Moved jumpers around and added more. That should be correct now. The manual lists UB43 as the Tag with UB48 as Dirty SRAM (schematic has it as ALT), so 32KB x 4 = 128KB, 32KB TAG, 32KB ALT.

btw, mobo trays are awesome, you use them as a test bench, and when happy just slide them in from the back and you're done, so convenient! Why dont they make such cases anymore? Some business-oriented machines still have them. I'm just glad many consumer cases still have rear cutouts behind the CPU …

Done some probing with the multimeter without a CPU installed. On a VCC pin: When set to 3.3v the board gives 3.52v. When set to 4.0v the board gives 4.03v When set to 5.0v the board gives 5.11v On the VRM (my board has a single VRM on the right side when looking down on the board from the VLB end …

If you mean the voltage then you can measure between any VSS and VCC pin (highlighted blue and red below) on the picture below. This is the pinout as you see in the socket. S4 on the pinout is the VOLTDET pin. I believe it needs to be grounded by connecting it to one of the VSS pins for the voltage …

I have a later revision M919 that has the proprietary cache slot and had the same issue getting an AMD 5x86 133 running on it. I found the same thing in that the chip doesn't seem to get hot. Supposedly there is a pin in the CPU socket you can ground which on supported boards will switch the …

You may need to desolder the keyboard connector and visually follow each trace and check them for continuity. The biggest issue I see is the power connector being right there and it may obscure your ability to visually follow some of the traces. It's not uncommon for what looks like a trace running …

IMO it looks like you have a gap between the 286 10Mhz and the 386 DX40. Using the turbo switch on the DX40 might resolve the issue, but there are games where that DX40 is just too fast. Your P233MMX on the other hand can be slowed down to cover everything down to that DX2-66. If you don't want to …

Quite a shame there isn't an easy way to install two graphics cards on a single old MOBO and just plug the monitor to whichever you need! If one was PCI you can plug both a PCI and AGP card in and Win98 will work. I remember games having selectors for which graphics adapter to use which made a lot …
