Hello all,
So I picked up a PS/2 model 25sx and saved it from recycle, and now trying to beef it up a bit and add it to my collection.
seems the 25SX model was a rare one, only sold to schools for education purposes so not much documentation on this particular model can be found.
It is a 386sx-20, with a 387 math co socket, has 4 meg memory on board, and one slot for additional memory, IDE hard drive interface, and 3 internal ISA slots, and VGA all packed into model 25 goodness =)
So far, I have tried every single 72 pin simms memory I have (only have 3, and one of them has ibm logo on it) and all give errors when I try turn the machine on with them, even after using the system disk to autoconfigure for them, so apparently they must not be the right kind of 72 pin for this system (anyone have any? id be willing to do some trades =) )
Current hard drive is 80 meg, although I would like to go with a much higher size, using an isa card ide controller if I have to, to be able to use a higher size and possibly even an ide-sd unit that I have (id love to use a 4 gig sd card with it)
or even the possibility of an isa controller card and run a cable out the back for maybe a cd rom? =D
today my ESS isa sound card came in the mail, I installed it, and can finally hear KQ6 with much better sound than the internal speaker
so what I need: memory,387 math co, OR 386-486 upgrade, ide controller card, and anyone elses experience and expertise on adding a much larger sized drive.
I can either pay for anything anyone has to help me, or do trading with the vast amount of hardware and items I have.
Thanks in Advance! =D
