[comp.sys.amiga] Amiga 500 Ram questions

schwager@uiucdcsm.cs.uiuc.edu (09/21/87)

.
Thanks to all who responded to my question about why I couldn't send an
escape char through PRT: .   I was indeed able to send it through PAR: .
Actually, if I had a decent manual I would have been able to find this.
I'll be picking some up soon.  Now, a couple more questions:
-Are there any expansion rams available for the A500 besides the A501?
-Correct me if I'm wrong: graphics images can *only* be stored in chip
ram, so if you've got an image stored in another place in expansion ram,
it has to be moved to chip ram in order for it to be displayed.

Well, MicroBotics makes a pin for pin replacement. Like the 256K 'nosepiece'
on the A1000 it does the same thing as it's CBM counterpart but costs a bit
less. They also have prototypes of (but I haven't seen any commercial ones)
of a StarBoard that plugs in to the left hand side (PortBoard???) Supra is
advertising a hard disk interface, although I don't know if you can add RAM
to it or not. (You can on the Amiga 1000 one)

This is correct, images can only be *displayed* from CHIP ram, they can be
*stored* anywhere.

These opinions are my own and no one elses. But you knew that, didn't you.

According to the recent issue of Amazing Computing, MicroBotics advertises
the A500 internal 1/2 meg expansion for $159.  It includes the clock, and they
claim its the same clock chip as the CBM version.  An overall $40 savings.

DISCLAIMER:  I have no association with MicroBotics other than reading there
	     ads.
