View Full Version : Question about the IBM PC 5150 system start

July 11th, 2004, 01:28 AM
Hello Friends

I've got an IBM PC 5150. The machine has the 256 kB board with memory card and a total of 512 kB ROM, 2 full-heigh floppyes, a monochrome video card with monochrome monitor (IBM 5151) and of course no hard disk.

The computer works fine and the PC-Diagnostic 2.02 don't report any faults.

But, while booting there is no memory-count-up. There is only a blinking underline while the computer is booting.

My Question: Is it normal for the IBM 5150 PC not counting-up the memory on system start or is it a fault?
Btw: My IBM XT 5160 is counting-up the memory.

Thanks for helping and greetz from Switzerland.

Yes, the blinking cursor is the normal start-up display for the 5150. The memory count came in later models.
