How it behaves on other machine which has the 2 LPT ports? Also if the machine has its LPT port adress something other? I have no other real machines with two LPT. I compiled 86-box emulator (PCem fork) from sources - It supports 2 LPT ports and can emulate COVOX on each of them. It can also …

how it behaves if you have not ticked that "Stereo", but have the LPT1+LPT2 ? It does not hang, but playing using only LPT1 port (0x378). I see with the help of some Verilog watchpoint that there are no calls to port 0x278 in this mode. The FT2 has also stereo playing capability with LPT1 only too. …

Hello, Recently, I made an expansion card based on CPLD Altera epm3256. The main purpose of this card is the logical analyzer of the ISA bus signals. In addition, the card has an SD and minijack 3.5 connector. https://cdn1.savepice.ru/uploads/2018/9/10/9ca36bff451203451d53d9fe6edced61-full.jpg …

Сheck with a multimeter that the A15 signal does not short circuit to ground (and VCC). Anyway, the problem is somewhere near the A15 signal.

Not a requirement, but I starts to run less reliable above 115 that's why I left if around 114. Thanks for replay. I remove all other clock for EGA and MDA. This allowed me to make proper clock for Poisk 15MHz CGA. Thus, now i have two firmwares - one for standart CGA/MDA/EGA and one for Poisk CGA. …

You have to disable all clocks and change the first to 120. But then I may not be able to set the others in the correct clocks. so you will probably have to remove the MDA/HGC and EGA modules and make only one for the poisk frequency. Thanks, i will try later. Should i change SRAM clock to 120 MHz …

Try to identify the poisk pixel clock Thanks for replay. Yes, you are right. Poisk use 15 MHz crystal for CLK, so CPU run at 5 MHz. I think pixel clock is also 15 MHz or similar, not 14.3 MHz. if you could manage to change the FGPA code I am newbie in FPGA, i am trying change PLL2 c0 clock to 120.0 …
