[comp.sys.ibm.pc.hardware] "MAXIMISER" expansion card for IBM PC/XT info req.

gary@brb.isnet.inmos.co.uk (02/06/91)

I have a friend who has what appears to be an original IBM PC/XT.
He has had some problems running certain pieces of software, which
may be due to lack of memory. He has 256k on the motherboard and an
extra 128k on a "MAXIMISER" add in card (using 64k DRAMS). The card has
enough empty sockets to be populated with a further 256k of 64k type 
DRAMS. I have the appropriate chips, but I am worried as to whether any
DIP switch settings may have to be altered. He has no information on the
card (it was installed by the previous owner).

If anybody has any information on this expansion card (or can point me in
the right direction) I would be very grateful if you could EMAIL me with
the details. There is very little in identification on the card, apart
from the name "MAXIMISER" and the date "!983". The card looks quite nice,
and appears to have a parallel port, a real time clock, a serial port, 
with an empty socket for a second serial port chip. I would like to know 
whether there is also a game port (a demo game disk acts as if the joystick
fire button is depressed ???). Additionally how do you make use of the
real time clock, as I assume that the XT's BIOS doesn't support it. Would
the board have originally come with suitable driver s/w????

Thankyou.
