Available - Xerox 820-II computer - has issues.

by tosteve＠yahoo.com

I have this Xerox 820-II computer and keyboard, but no drives. It boots-up to the selection menu, does not respond to either of the two keyboards I have. Is this worth anything to anyone? Steve in Southern California 92656.

Thank you for the lists. That's exactly the kind of document we were looking for. Although I don't see why there's any need to get so cranky about it. :-/ > Message: 1 > Date: Tue, 27 May 2014 10:13:15 -0700 > From: Al Kossow <aek at bitsavers.org> > To: cctalk at classiccmp.org > Subject: Re: Listing of 60s mainframes/minis with CRT displays? > Message-ID: <5384C7AB.5010209 at bitsavers.org> > Content-Type: text/plain; charset=ISO-8859-1; format=flowed > On 5/27/14 10:05 AM, Richard wrote: > > I'm sure there are many more, but my most easily accessible sources > > > http://bitsavers.org/topic/graphics > I've done a ton of research on this topic.

How to create a CF boot DOS

by enrico.lazzerini＠email.it

Hello to all, frankly I think I'm in a loop. Let's see the summary . Ultimate goal : to install a Compact Flash card <http://www.memoryc.com/images/products/b/adata-2gb-cfc-speedy_4711.JPG> http://www.memoryc.com/images/products/b/adata-2gb-cfc-speedy_4711.JPG on a cf- ide adapter <http://img.dxcdn.com/productimages/sku_0711_1.jpg> http://img.dxcdn.com/productimages/sku_0711_1.jpg on a controller PTI- 227B V2 <http://www.rainbow-software.org/manuals/pti-227b.html> http://www.rainbow-software.org/manuals/pti-227b.html into an IBM PC AT 286 5170 <http://www.vintagesbc.it/?page_id=838&gtlang=en> http://www.vintagesbc.it/?page_id=838&gtlang=en Not being sure of anything I have designed different steps. I ask for help for the first one that is : Make sure that the Compact Flash <http://www.memoryc.com/images/products/b/adata-2gb-cfc-speedy_4711.JPG> http://www.memoryc.com/images/products/b/adata-2gb-cfc-speedy_4711.JPG on a cf- ide adapter <http://img.dxcdn.com/productimages/sku_0711_1.jpg> http://img.dxcdn.com/productimages/sku_0711_1.jpg to boot on an old PIII PC <http://it.gigabyte.com/products/mb/specs/ga-6vxc7-4x.html> http://it.gigabyte.com/products/mb/specs/ga-6vxc7-4x.html that I normally use to transfer files between different diskette's formats and disk that has as OS Windows 98 and its relative DOS . I can also load on it a DOS 3.3 , and so on. If this works I will can try the union of CF + adapter + controller on the same PC and then follow again all into the IBM PC 286 . I premise that the PIII's bios made available to me to set the automatic recognition of geometry of the HD connected once and forever to be sure to not have discrepancies for HD and even for the Compact flash card at each turn on of the computer. Anyway from its bios I can always choose from which drive to boot from . Yesterday , I took an old IDE 6GB HD , I partitioned it to 2GB with a DOS3.3 ( with FDISK first and then with format / s ) so I launched Acronis CD to make a clone of the HD partition on the compact flash . It took a bit to do this perhaps to resize the copy . At the end , however, the boot did not work the same. It was the last attempt after days of testing . Imagining that on a compact flash perhaps the BOOT sector might be seen differently (being theoretically removable) compared to HD . I found an interesting document <http://thestarman.narod.ru/asm/mbr/STDMBR.htm#CHS> http://thestarman.narod.ru/asm/mbr/STDMBR.htm#CHS but it is too complicated for me . I thank you for all your straight. Otherwise, I give up . Enrico

Macintosh Basic?

by rob＠bitscience.ca

Does anyone have a copy of the original ?Macintosh Basic? that they?d be willing to share? What I?m looking for is the version of Basic that was written by Donn Denman et al. at Apple in 1985 or so ? have a look at http://www.folklore.org/StoryView.py?story=MacBasic.txt if you don't know the story. Beta copies were widely available in the user-group community at the time, but Apple ?cancelled" the project before it officially shipped; I recall having a copy myself in early 1985, but I can?t find the disk. I?ve done some searching online, but it appears not to be available in the usual places. Feel free to contact me off-list. Thanks very much, Rob Ferguson rob at bitscience.ca

DataGeneral Model 10,20,30

by supervinx＠libero.it

Hi! I acquired a DataGeneral. The label on the back says Model 10,20,30. I powered it up and noticed white smoke. It looks like a RIFA capacitor burn, since the fan kept spinning and the smell was the RIFA one. Do you have a link on some PDF infos? I'd tear it apart without breaking something. I checked the cards and they looks OK, so the HD, floppy drive and tape. The two PSU modules are tied to something on the back. Plastics seem a bit fragile, so I'm acting carefully :) Thanks!

Catch and Halt Fire - Drama set in early days of persona

Morse wrote much of the unit-record IO drivers for VMS, and then maintained them for some time. They must have started the VMS project in about 1975 to get the machine ready to sell in 1978. I know Kathleen was there for quite a while before that, I THINK she was on the cover of one of the minicomputer handbooks from DEC. I spent quite some time reading her code when hacking printer drivers and such. If you searched the VMS source code for her initials "KDM" I'm sure they appeared many thousands of times on patch ID lines. Jon

Catch and Halt Fire - Drama set in early days of personal computing

by terry＠webweavers.co.nz

I see this is to be broadcast in the U.S. soon. http://www.stuff.co.nz/technology/digital-living/60069626/pc-tv-series-to-d… In fact if you live in the U.S. you can see the first episode apparently (I can't here in NZ...it's blocked). http://blogs.amctv.com/halt-and-catch-fire/2014/05/watch-a-sneak-preview-of… Anyway, I thought some of this list might not be aware of it and might find it interesting. Will it inspire more people to take a look at earlier personal computing history I wonder? Terry (Tez)

Question about SIMH .TAP files

by rickb＠bensene.com

The username field in the archive is of the form used on CDC Cyber computers running NOS or KRONOS. University of Illinois was big on CDC machines. I bet it is some kind of archive format used on CDC machines to create tapes that could be interchanged with other types of systems, e.g. IBM. I wish I could remember more detail from my Cyber operator days, as I do vaguely remember that there was a utility that we ran to create takes in a format that the big IBM systems on the business side of the company (Tektronix) could read. Please excuse top posting, my phone won't let me post any other way.

Good catch--the tape's from UIUC. --Chuck
