I just had the same unpleasant surprise as Mr. Khoe. I booted up a
2 Meg A3000 from the system so thoughtfully preloaded on the hard
disk by C= and found the following :
    866... bytes of graphics ram available out of 1 Meg = 1,048,576
bytes installed. So about 162,000 bytes of graphics memory are being
used by the system. I assume this is for the system neucleus and the
graphics screens.
BUT only 220... bytes of other (fast) ram available out of 1 Meg fast
ram installed ???
Mr. Seymores posting and one by Mr. Uszumn explain where 512K of the
fast ram has disappeared to. The RAM: disk accounts for another 16K.
But what's eating up the remaining 270K ??
On my 512K A1000, after loading up about 60K of my C directory to RAM:
and getting rid of WB, Is still have about 280,000 bytes available in
cli mode.
Also the A3000 is one of those that has a 50 Meg hard disk. (Again
praises to C= for their generosity). It comes with two partitions
5 megMEGeg. for SYS: and 41 Meg for WWRK: But where are the remaining 5
or so Megs?? On my IBM PS/2 the 40 Meg. hard drive has 40 Meg.
available for me to use.
I hope at least that the 4 Meg. of expansion ram due to be added
to the A3000 will all be available.
