Hi, It seems there is another solution now. But it use a FPGA, and not Bare Metal Pi. Too complexe solution, but good to have somebody else working on it as well. https://www.youtube.com/watch?v=1ej76w8sHxY Edit : He already did videos with FPGA on ISA, I remember them.

For tech support, you can mail this guy directly: mj@wch.cn (or tech@wch.cn). I bought random card USB ISA from AliExpress and it just contains the WCH (CH375) chip, so then you contact the manufacturer of the chip. That's what I did. It does not matter, who made the PCB (Lotek or Ali). By default …

The way the CH375 Chip is done also limit everything. This chip has a 64Bytes buffer, so we need to send another read command and wait the end of the transfer, after each block of 64 Bytes. Then, we need to add the time of the transfer to the CH375, then the transfer time to the ISA Bus and the " …

So, does it make sense to use the new 286 driver on a 486DX4-100? Will it work and give faster speeds? Even if Retro Eric answered :) I would like somebody to try, because in theory, it should work. You may need to add a value in the delay. In the 286 version of the driver, I did remove the delay …

Hi, Interresting, i never heard about the live sample swap. Do you have files using it ? There are différent version of tracker on the amiga, with différence between them. Then I am not convinced there is only one way to play music. Sometimes, musician use tracker bugs to do a different effect.

Hi, It is strange, it is too slow.... Are you sure you used the good one ? The CH375216.SYS I shared was buggy, I published the correct version on the Vintage Computer Forum thread. But you need the LoTech for this.

4 channel mixing @ 30kHz on an 8086 8MHz without stuttering is really amazing. I'm also a bit amazed at how fast the 150kB module loads to RAM after you select it in the file browser. Feel like sharing the source code? Hi, The maximum mix speed depends on the module as well, if it does not need to …
