@i386, I actually disabled the motherboard cache (it is 1MB, 4x256kb + 1 tag chip) since the cpu is doing the caching. This is not the 2mb board. (it has the chip outlines but not the correct chips for 2mb) anandtech actually reviewed the 2mb board and it made no worthwhile difference over the 1mb …

maybe a Microstar model? several hits around for '121291-CTQ' but its all unknown. probably lowest price taiwanese mobo around at the time, company couldnt even silkscreen their mfg name on it. http://www.kva.kursk.ru/bios1/HTML1/microstar.html
My SS7 build is complete

So after building and loving to use my 486 isa backplane shoebox PC, it became apparent I had too many demos and such that really needed a pentium class CPU. So my plan is to decommission the 486 box and upgrade it to a Super Socket 7 build. Back in the day, I used to have a AMD k6-200, the first …
Re: What retro activity did you get up to today?

Recorded Vangelis - Chariots of Fire on my SoundEngine + SC88VL to do some comparisons. The waveform on the soundengine seems much cleaner. This is recorded directly from the mixer into the recording hardware. Just trying to find songs to test different sounds/samples on the soundengine and see how …

I hexedited Norton Utilities ncache2.exe to work under dos 7.10, got sick if it telling me it wont run under windows dos, since I run 7.10 stand alone without windows I dont care about its error message. Now it works 😜 🤣. Simple 1 byte change.

Personally, Id just target pi3, it has the best performance. adding stuff to target the much slower pi1/pi2 is pointless imo. Until Raspbian gets a 64 bit version, Pi 2 and Pi 3 are kind of the same thing from a software perspective. Yeah. Im only aware of the arm8-a (pi3) having CRC instrutions …

You can start with a prebuilt image or follow the instructions to install it yourself: https://www.vogons.org/viewtopic.php?f=29&t=46899 That will come in handy. At this stage I don't understand most of the commands, but nothing a bit of researching and reading can't solve :) But I wonder, how do …

well odd/even just meant the mfg used cheaper lower capacity eeprom than one larger one back in the day. easy to use the lower address line as a chip enable toggle and do odd/even. the performance going from an odd/even two chip to a single chip should be zero, the lowest address line on the card …

fluidsynth comes with a 128mb GM soundfont that is pretty awesome. sudo apt-get install fluid-soundfont-gm fluid-soundfont-gs and it appears in /usr/share/sounds/sf2/FluidR3_GM.sf2 GS sf2 is only like 3?mb, in same directory.

I also see it more with memory intensive stuff, aka doing an ftp from my server with mtcp.

ram refresh timer would be odd, since its sram, no refresh required. I might look through the bios, look over the interrupts entry/exit points make sure a register is not being corrupted or something dodgy with stack is going on

Yeah. Sounds like what I am seeing. I was REALLY sure using USE!UMB (I didnt use himem.sys) was causing it WAY WAY more than not to lockup that I stopped using it ages ago. Worse, while it happens every time, the amount of time it takes to lockup on me is random. I also see odd program behaviour, …

I get random lockups. sometimes its quick after bootup, couple of minutes. sometimes its long time after bootup, but pretty much it happens all the time. I thought it was my vga card (since I have some issues with it). I had nothing but that in the machine and I was getting it. I did seem to ( …

Yes. Its a GM module but it has two modes, GM and a Proteus mode. It also has a DSP for reverb and chorus which waveblaster lacks. I need to find/create a midi to just send the sysex message to reset it into midi or proteus mode. Its soundfont is 4M in size

Picked up this, EMU SoundEngine (aka the refined/last version of the WaveBlaster daughter board in MIDI module format). Been after one for a while. Needs some cleaning up and small amount of attention before it goes into the stack; I was hoping for a later version but its an early version. Main PCB …
