Just tried it on my 386DX/SW-20PC combo... I cannot detect anything different with the extra files or not... explosions and fire sounds are missing for example. I get these on my 233mmx/SB16 build though.

the datasheet states that all you need to build a soundcard is this IC and OPL2 or OPL3 (well you also need glue logic and opamps - that goes without saying 🤣 ) , it offers playback/recording/uart midi and joystick functions... most likely it's a SB Pro compatible chipset as well...

it's just a yamaha-based sound card with OPL3 and scsi connector , one would need a port converter to plug a joystick... more pics at the auction : http://www.ebay.co.uk/itm/201651544231 YMZ263B-F datasheet: http://pdf1.alldatasheet.com/datasheet-pdf/vi … /YMZ263B-F.html

Yeah you are correct, you select the correct IC on the programmer software, it auto-configures and then you work with it. For UV eproms the writting voltage will always be bigger than the 5v read one... don't pay attention to these settings, you don't need to mess with them ;) W27C512 is an eeprom, …

First you need to know what ERPOM you will be replacing. If it is a 27C512 type then a W27C512 is the eeprom equivalent and just works. W27C512 will work as a replacement for at least 27C128 and 27C256 , these are just 16 and 32kbyte eproms so you fill the remaining space of the W27C512 with the …

Maybe this can be fixed with the tv's Service Menu , there are many options there regarding geometry - at leasts at my sets. You need to somehow get the service manual of your tv DK , maybe there is a PDF floating around

@Great Hierophant oh yeah, the SC-50 is the one I was thinking of, I stand corrected @kirikl you can try PLAYMID.EXE that is available for download here: http://www.philscomputerlab.com/ultimate-rola … 2-tutorial.html , it's a small command line player

Ah, I was under the impression that clocks should be very precise to get correct colors, I stand corrected 😀 Is there a possibility to check with a loaner cga as well? Maybe it's the card at fault, could be the case some 74xxxx fails after a while and messes things up...

I would look at the caps before messing with the oscillator personally, if it's not at fault don't you need an oscilloscope to tune it back at the correct frequency so you get correct colors?
