Computers Manufactured in 1986

by healyzh＠aracnet.com

> What are some good old computers manufactured in 1986? Well, since I don't think DEC was still making PDP-10's at that point, that means you're limited to various PDP-11's, VAXen, and the Macintosh. Zane

OT: MS/Unisys Have Made My Day

> The M$ foot gets another dose of lead Ummm, Doc, I think you fell for an April Fools prank. If you view, say, http://www.wehavethewayout.com/xxx you get a standard IIS 404 page, and the HTTP response header say "Server: Microsoft-IIS/5.0" I think Microsoft learned its lesion when it took, what, a couple of years to migrate Hotmail off of Unix onto NT/2000? Or did I fall for the prank by responding? :/ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- _| _| _| Brian Knittel / Quarterbyte Systems, Inc. _| _| _| Tel: 1-510-559-7930 Fax: 1-510-525-6889 _| _| _| Email: brian(a)quarterbyte.com _| _| _| http://www.quarterbyte.com

CP/M and Imsai

From: Don Caprio <caprio(a)dcms.com> >I purchased an Imsai 8080 and would like to run some version of CP/M. >Should I stick with Imsai's IMDOS, which we know works? If CP/M is doable >What version would be the best choice? Cpm is doable on ANY 8080/8085/z80/z180/z280 machine with the minimum of: 20k of ram {16k for V1.4} Console IO device {serial, parallel or video} Some form of block addressable mass storage device {disk, tape or rom/ramdisk} Nice to have: Boot prom/eprom (doesnt have to be big) Second port for printer hard disk >Does CP/M need some sort of BIOS like the PC? If so where do I get the BIOS >source in order to burn an EPROM? CP/M does (invented) the idea of a bios but.... it is not resident firmware as in PCs. It's loaded at boot time from mass storage. A BIOS for the DISK CONTROLLER and CONSOLE IO may or may not exist depending on YOUR specific configuration. S100 system could vary a lot and were not anything close to plug and play. However, you could write your own bios and there are plenty of examples out there as well as the docs needed. Allison

> -----Original Message----- > From: Torquil MacCorkle III [mailto:torquil@rockbridge.net] > Which SGI would actually have an R2000? Um, none of them. IIRC, R3000 was the first chip that SGI used from MIPS. There are other systems that use them, including some (I have some r2ks, I think) made by MIPS, themselves. An SGI from that period is something like the IRIS 2000, or possibly by then IRIS 3000, which was very large and based around a motorola 68k chip of some sort. Great machines, but they don't fit your relatively low power requirement, and they're as large as your desk easily. :) Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

Rumor has it that Christopher Smith may have mentioned these words: >> -----Original Message----- >> From: Roger Merchberger [mailto:zmerch@30below.com] > >> (under OS-9) 512K Ram, hacked easily to 2M (recently hacked >> to *64Meg*!!) > >Ok, when I get a CoCo 3, I want it to have 64M of RAM. How's >it done? :) http://home.wwdb.org/irgroup/nocan3b.html He's got it to 8Meg here, and said that 16Meg should be no problem... I could have sworn (albeit not with my life) that he had a proto running 64Meg, just to see if it could be done, but with a very quick perusal I couldn't find reference to it again... but I did find reference to RAMZilla, which didn't have a direct link, so I think that was associated with it somehow. Drat... but admittedly, *filling* 64Meg on a CoCo would be a chore in itself, unless you wanted one _big honkin'_ ramdrive. He's also got a wire-wrapped CoCo listed elsewhere on the page... Gotta get back to work, Roger "Merch" Merchberger -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig. If at first you don't succeed, nuclear warhead disarmament should *not* be your first career choice.

This one I can answer. Yes, it does. -- and -- EPROM? Who needs an EPROM? (CP/M BIOS is stored on the floppy and loaded into RAM, generally.)
