Cool stuff, Thermalwrong! Thanks for sharing the pics. That's a rare card, i've seen it for sale only once in many years. And quite unique too - the only one to have a built-in speaker. Good to know it uses es1488 chip, will update my chart.
Do you know what kind of connector it uses?

Indeed, thanks for sharing those pictures, Thermalwrong!

Does anybody know if the GAMEjammer is compatible with the WAVjammer (or .WAVjammer), also by New Media?

I'm asking this, because the (.)WAVjammer is, to my knowledge, the only PCMCIA sound card that has native support in a number of later DOS games.

Hey, Digger 😀
Nope, GJ doesn't have native support in games like WJ does. They seem to use different chips. As according to NM website GJ supports 8bit mono sound while WJ supports 16bit sound and also 11 voice OPL2 vs 20 voice OPL2. https://web.archive.org/web/19970118220337/ht … orp.com/gj.html
Not sure why that is, though, as es1488 is a 16bit chip.

Thanks, Bondi! 😃

I got a similar answer from Gemini. From what I understood, the GAMEjammer has native Adlib compatibility, but no native DOS support for PCM samples, as the WAVjammer does with at least some later DOS games that used Miles Sound System 3.0 drivers.

I have no idea of what connector it uses 😒 I found some pictures of the dongle but nothing hi-res so nothing that helps me.

Here's a decent resolution picture of the connector from the outside:

I've probably got some fine pitch connectors from LCD cables that I can jam in there to get the joystick output working and hopefully I can work out the pinout without opening the card up again. You can see from the connector picture that it didn't stick back together like it did from the factory...
Since the FAQs for the GameJAMMER said it only supports 2 button joysticks, perhaps I should assume that it only supports one joystick, pretty realistic assumption. Then the midi out/in, VCC/GND and joystick pins take up around 8. The audio outputs and inputs should be those pins with the grey SMD components (inductors).
It's got 6 pins in one segment and 9 pins in the other. I think the audio parts are in the 6-pin segment and the joystick is in the 9-pin segment.
I really don't want to take the card apart again and picture the back-side as well if I don't have to.

---------------
eh, I did give in and take it fully apart after all. Here's the front and back:

Here's where my tracing has got me so far, it's a real shame that there's no known pinout for the ES1488 chip:

11	negative of C28, a 16v 10uf capacitor. + goes to 34072.1		no idea yet, maybe line-out, 34072 is an op-amp and pin1 is 1out
22	goes through inductor, resistor, capacitor then ES1488F.1		mic input?
33	goes through resistors R2 & R21, then to ES1488F.6				line input?	
44	ground															Analog Ground
55	ground															Digital Ground
66	goes to XC3042A.24 (VCC pin), also PCMCIA VPP (?)				Seems to be VCC
7
87	through a transistor, goes to LM4861M.1							LM4861M.1 is the shutdown pin. possibly a loopback on the cable possibly to turn off internal speaker
98	through R1 then NE558D.7										joystick axis
109	through R1 then NE558D.2										joystick axis
1110	through R1 then NE558D.15										joystick axis
1211	through R1 then NE558D.10										joystick axis
1312	through a resistor around R8, then to ES1488F.52				Midi I or Midi O
1413	through resistor around R8, then to ES1488F.19 (???)			Midi I or Midi O
1514	XC3042A.23														probably a joystick button
1615	XC3042A.22														probably a joystick button

The form factor makes it difficult to test the card while it's open and the laptop's on. Maybe I can use my T2400CS to do that with the palm rest removed. Probably easier to make up a cable though.
