Pixel AP80
Mike Squires says: I am about to pick up a Pixel AP80 that was contributed to our College. If there is anyone out there who can tell me something about the care and feeding of this beast, sources of software, hardware, etc., I would be most grateful...

UNIX for 68000
Mike Shanzer says: We're trying to find a 4.2/4.3 system that will run on a Pixel 100/AP. This is a 68000 box from a couple of years back. We have an AT&T System V source license and are looking for sources. Does a Mt. Xinu version of 4.2/4.3 exist for the 68000? If there isn't a 4.2/4.3 version around, we will consid

Need UNIX VMEbus system recommendations
George Hart says: ...Motorola Computer Systems & Four Phase sell the System 8000 which is 020 based with a 380mb SMD drive. Comes with SysV/68, R. 2 with R. 3 in the pipes. I believe the processor runs at 16mz (there are faster processor cards available) and there is an onboard cache. With the right serial cards and

Re: What's Nu with VME for Mac?
Steve Ligett says: ...From what I know of Apple, whether or not there are add-on products might not be a factor in choosing a bus, or what you see as a negative, they might see as a positive. disclaimer - I don't know what bus Apple will use.

What happens if I do a lot of moves to ss
tim@ism780c.UUCP says: Oops! I didn't notice that that was cross-posted to comp.sys.m68k! Sorry about that. I decided to post that article while reading news, so I picked a random article in comp.sys.intel and submitted a followup, changing the subject and reference lines. By chance I picked one of the Motorola vs. Intel

Re: Re: What's Nu with VME for Mac?
John Gilmore says: ...Perhaps by now they do. I know they leaned on Tapemaster for years to get this solved. The point remains that using big endian byte order on the Multibus was a hassle, though the market eventually moved to make it easier. I presume that if enough people build little endian VMEbus systems, the sam

need to rent time on NCR/Sperry Tower - yours?
lindsay@gitpyr.UUCP says: A client of mine would like a backup machine. He's putting his payroll on a UNIFY database on an NCR Tower SysV machine. What is he to do in the event of a 2-3 day hardware failure? His solution is to rent time on your machine, restore a small backup (a larger backup if you don't have UNIFY), run hi

Re: Re: What's Nu with VME for Mac?
Jim Omura says: ... I think we're not looking at the problem the same way. As such I think I'm not in disagreement with you or the original article anymore. In terms of buss signals I expect you're right (I'm not going to bother checking). I was looking at it from the historical development. It was developed out of

Reading m68k data files on SVR2
Swanson says: Does anyone have an algorithm or program for reading a data file written by a program compiled with AT&T SGS 68000 C and run on the 68000 after it has been transported to a VAX running SVR2. I would like to be able to use the same header files which were used to write the file to read the file. Any

ICE wanted for 68020 at 16MHz
Roy Gordon says: We are (desparately) looking for an ICE. The target machine is has a 68020 processor running at 16 MHz. (We have an HP64000 system and I know we can buy a board that will allow us to use a 68020 with it. However, the maximum clock speed we can run the 68020 at is then 12.5 MHz.) Any suggestions will

Re: What's Nu with VME for Mac?
Jim Omura says: I just read Cliff's posting with the quotes from the magazine article about the various busses. From what knowledge I have, I have some doubts about the quality of the article and I would like to hear what other more knowledgeable people could say about it. What stuck out in my mind was the blurb on

Re: What's Nu for VME.....
Thomas H{meenaho says: ...Three things about the NuBus I don't like: 1) It allows only 16 slots. 2) It's block transfer mode is awkward compared to the VMEbus one. 3) The boards are HUGE. Ok, when designing complicated boards it is nice to have a huge area at hand but it makes the system big! One other thing I think shoul
