If it is a CT2760 it should say so right on the card. It looks like it might be but the picture you attached is extremely low resolution so it´s impossible to see anything specific there.

I have found out that two of the boards I intend to update have 28 pin chips so for those I can use the W27C512 that was suggested. However for the board that use 32 pin DIP chip that needs 128kb (1 mbit) of space, what chip do I need there? Does someone have a model number so I know what to order? …

Which motherboard do you use ? most 486 motherboard use 64KB ROMs which are very often compatible with 27C512 chips, but some socket 3 boards use 128KB chips of another kind (same kind as later pentium boards) There are a couple of motherboards, I don´t have access to look at them right now but one …

I want to upgrade the BIOS on some socket 3 motherboards. What kind of chips does these motherboards usually use and what size is needed? Can you use a larger size than needed or do they need to be exact? Is it possible to use EEPROM chips so I don´t have to use a UV eraser if I want to erase them? …

Thanks folks. I wasn't aware of the 11 khz thing. Is there a recommendation for an alternative card to add in for digital/MIDI other than the relatively expensive Hard MPU card? The best choice for something that just works in my opinion would be this card http://www.pcmidi.eu/ Not the cheapest …

In my experience the slowdown/pausing in Duke 3D and TIE fighter is so bad that it makes the games unplayable. I haven´t tested this extensively but I remember starting the games and going "this is unplayable in practice" and getting a dedicated MPU-401 card. AFAIK, that is only present if you run …

Does that mean that I read the markings correctly on the inductors? Not exactly, brown/green/brown/silver = 1/5/1/10% = "1" + "5" + 1 * "0" = 150 uH with 10% tolerance Not sure if we are misunderstanding each other and you are talking what the markings should be for it to add up to be 150 uH, but …

Just a small update for posterity in case anyone else has similar problems. The clear CMOS jumper was indeed there on the motherboard but it wasn´t actually a jumper, just 2 solder points that could be shorted. I spent some time fiddling with back and forth of Dallas chips and clearing the CMOS to …
