Unix for 8080/Z80? [Re: WooHoo!! PC/XT Unix anyone?]

by allisonp＠world.std.com

<This notion of cooking up or breathing new life into an old 8-bit model to <run *NIX is probably a mite more than has been considered for one reason. <*NIX tends to want to use virtual memory, without which many systems would <quickly choke. The old CPM-capables don't support VM. A good reason for <this is probably the lack of performance. Unix didn't always have the idea of virtual memory. See Minix for an example of that also V4 and maybe V5 unix didn't either. Also It's been done! UZI uses the total swaping model, IE: processes are swaped out of core to make room for others. Allison

FYI: MEI/Microcenter is out of 5-1/4" diskettes

I'd better start hoarding them... You can still buy 8", 5.25" HD and 3" disks. Trouble is, they may be *Really* expensive; I noticed on the Imation web site a couple of months ago that (from memory) a box of 8" disks was over US$100. 3" disks are still available new from at least one place in the UK, though they are over 2 pounds each. -- Mark

Legitimacy of the Ten Year Rule.

by netcafe＠pirie.mtx.net.au

I personally feel the 10 year "rule" is useful as a guide, however, I also consider that there are several machines that rightly qualify as "Classic Computers" that are less than 10 years old. There is a particular "grey" area in that a particular machine might span the period. I suppose logically, we should look at when a particular box was FIRST made. I have 2 Vax 6000's here (which I propose to the list are a "Classic" regardless of age") one is 89 manufacture and therefore (just) 10 years old. The other is a 1990 build. Microvaxen have been around for a fair while now, but I am given to understand they are still orderable, new, from Digital. IMHO, I would also class ANY Microvax as a "Classic" regardless of age. In fairness to all, it's unlikely that we want to see extensive discussions of the vagaries of Pentium II's discussed here (for some years at least!) but I am confident that the 10 year rule is meant to guide us, not shackle us to a time frame. i.e. IF you have a machine that is less than that age, or you wish to discuss it on the list, and IF you consider it to be a classic in it's own right, then I suggest it be put to the list. IF the consensus of list members is that it should be classed as a classic, then so be it. Just my 2c worth. Your opinions and/or mileage may vary.

Linux and 8" diskettes?

by dwollmann＠ibmhelp.com

I've been thinking about trying to use my Microtech 8" drive unit, which is attached to a fairly standard FDC, to read IBM 3740-format (Sys/23, Sys/36, Displaywriter, etc.) diskettes from Linux. I did some reading on 'fdutils' and found one brief mention of 8" diskettes, but nothing really useful, for obvious reasons I guess. Has anyone tried this or anything like it on Linux? A lot of the 8" diskettes I'm getting from customers these days are in poor shape and the Microtech drivers don't handle hard errors very well. I'm hoping the Linux driver is a little more persistent and will allow me to recover more data with less hassle. If only I could read all the bad diskettes on the Displaywriter--that thing will grind away on a diskette all day if it has to and rarely fails on a hard error. I wouldn't normally bother the list with this, but getting Linux installed on this box is going to be a major project and if it won't work I don't want to invest the time and money. -- David Wollmann DST / DST Data Conversion http://www.ibmhelp.com/ ICQ: 10742063 AIM: FathomS36

Legitimacy of the Ten Year Rule.

by hhacker＠gte.net

Given that Classic Computer(s) list members can agree on a standard for the application of the term "classic" with regard to collected computing (and other) hardware, is that as far as it goes? Perhaps there is more to value in the discussion. The act in which we all participate, the collection, repair and restoration, and operation of collectable computers and software has become vogue. Hence, given our collective expertise on this matter, it is our opportunity to effect the language and propriety of our activity. I am sure that many would benefit from a formal presentation of the collective view of the propriety of applying the term "classic" to a computer, etc. To do so would not be different from the same activity as applied to antiques, numismatics, philately, etc. It is exactly in this way that these, and other, standards of collectability (a measure of "value" not necessarily economically justifiable) are derived, becoming manifest. I think that we would be doing ourselves and our activity justice. What say you? William R. Buckley
