My PS/2 Model 50 has developed some problems, and I was hoping someone in net.land could offer advice about what to do. The IBM 8513 Monochrome display on it works with other computers, and the IBM keyboard appears to be okay (I have no way of confirming this.) The last time I used it, the 20 Meg HD and 1.44 Meg floppy drive both worked fine. When I turn on the power, the fan starts up, the speaker clicks (good news, yes?) and the hard drive emits the usual startup sounds. However, numbers (the usual "128K...256K...384K...") do not appear on the screen and absolutely nothing else happens; the speaker does not emit any beeps and none of the drive lights come on. The IBM repair manual says "Have the unit repaired." Mucho Gracias, IBM. Other advice includes "Reseat the chips", "Check the connections" (already done), "Reinsert any cards", "Call IBM" (I dont know the number). Anyone with any advice is strongly urged to mail it to me or post it in comp.sys.ibm.pc. Thanks in advance. sfn20715@uxa.cso.uiuc.edu or (217)-485-5541. (Ask for Steve Norton)

I've seen a similar problem on a model 60. It tuurned out to be an incompatible set-up file for an option board. Strip out all the boards that you cant configure with a standard config disk. Then one at a time put 'em back in. In my case it was an AST memory expansion. If the memory board isn't set- up correctly it will ock the system this way. BTW it took an IBM field tech 4 days to figure this one out. So much for "superior" architecture!
