Newsgroups: comp.sys.zenith.z100 Subject: Re: Configuring S-100 RAM Message-ID: <9003130005.AA17160@decpa.pa.dec.com> Date: 13 Mar 90 00:11:28 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 13 Thanks, Gern. I have a 192K motherboard, and these non-Zenith cards were used successfully in another 192K motherboard HZ100, both stuffed to 192K. S)ystem in the monitor verifies 192K of contiguous RAM. I did not change the switch settings from the other HZ100, so presumably the problem lies with my version of the monitor ROM or DOS. I am unsure of both what addresses they belong at and which part of the software is responsible for configuring them. I have two 64kb boards. rcs
