IBM's braindead decision to have 5 (instead of 8)
expansion slots meant
that aftermarket "multifunction" cards became quite popular. MANY of
them advertised SIX functions; after memory, serial, parallel, and
joystick, how many people remember what purported to be the other two
functions?
#5 was the battery-backed-up real-time clock, and I have this vague
recollection that #6 was something not directly on the card but
software which used the card, something like a RAMdisk driver.

I was joking when I said real-time clock since I thought the PC came with
a real-time clock. Is this not the case? Hmm, come to think of it, I
guess not since I don't see a battery on the MB of this 5150 here.

The real IBM PC and XT computers did not have a real time clock built in.
There were a number of third party cards that were available that provided
a RT clock as well as the stuff already talked about. Some of the clones
though did have a real time clock built in along with the associated
battery. The HeadStart is one that comes to mind, and I *think* the Leading
Edge Model D was another.

New subject: PS/2 external storage device cables
I just put these on a newsgroup, and realized somebody here might need
them. I found 3 new old stock IBM 23F2716 cables in a box I bought. I think
they are for a model 70 external floppy drive, looks like a HDI30 to DB37F,
but thats just guessing. $5 each and shipping.

The DB37 work by number of pins, but the only external floppies I've ever seen
from IBM for the PS/2 line were the 4869's which
had a cable built into them.
Too bad you don't have a digital camera or video
capture unit to diplay them
with.
