While we're not on the topic, please tell me... is light "really" a particle, or "really" a wave? How about electrons? - Joe P.S. No, I am *NOT* serious, I do *NOT* want to read such a discussion.

Sun 1/100U ... it LIVES!

by lemay＠cs.umn.edu

My Sun 1/100U lives once again... reseated the boards and realized someone had removed the ram board. I just happen to have ram boards that came from a sun 2 server, and poof! It lives! The monitor is in pretty good shape, the image is shifted a bit, but it looks like its mostly if not all visible. The main problems are: I have no idea how to enter the local prom mode, or even if there is a local prom mode.. Whups! Looks liek one way is to let the computer time out on its boot attempt. I still cant get any help on available prom commands. 'printenv' printed a small hex-dump like thing, then immediately the screen cleared and rebooted... Anyways, main problem is going to be locating the OS for this computer. Does anyone have SUN OS for a Sun 2 class computer? I forget what its called, suntools or sunview or something like that.. -Lawrence LeMay

hamfest and HP cables

by rigdonj＠intellistar.net

I just got back from the opening day of the Orlando hamfest. So far I picked up an Apple IIc plus, three more Compaq Portables IIIs, three HP 97s, a HP 92, two old HP catalogs and two old Tektronix catalog and this is only this first day! I also found some HP cables. They have a DB-25 female connector and a 36 pin Aphenol connector on the other. They have part number 13242D on them. Anyone know what they're for? Joe

M SoKit 68

by lwalker＠mail.interlog.com

In 1983 at the end of taking a digital tech course at a community college here in Toronto at George Brown CC, I spent about a month assembling and debugging a trainer kit that my prof was marketing, similar but more sophisticated than the Heathkit ET34400. It was called a M(icro)SOKit 68. It was based , of course, like the ET3400 on the M6800 CPU. Does anyone have one of these out there ? It was geared to teach students about micros by building their own micro. I know he sold a number of them, but don't know how many. I have the manual, parts #s, etc. if anyone is interested. Included in the manual is a couple of pages of layouts obviously meant to be photocopied and etched. ciao larry lwalker(a)interlog.com

by allisonp＠world.std.com

<But wasn't the mini-floppy actually produced by iCom, and then labeled as <a MITS product after Pertec acquired both MITS and iCom? What's the <copyright date on your docs? Yep, I have one of those. An Icom frugal floppy but that was 1771based. Allison

E-Over Pay strikes again! original Altair disk sells for

by allisonp＠world.std.com

<True enough I'm sure. MITS also produced a "mini"-floppy controller that <was also a two board TTL set. The first board (computer interface) was th <same board as in the 8" set (except for different RC values), the second Well heres where I stand on it. Never seen one, I was there, and never seen an advert for one, I have back issues. Was it possible, sure. The 8" design with some tweeks would certainly do minifloppy. Allison

Graphics board APOLLO 400 Two subjects,one message

by amirault＠epix.net

HI All, I need some help please. I have an ATI small wonder graphics solution Ver. 2 P/N 18703 Rev.0 copyright 1988. I also have a DTK model PIP-151 W/8088 CPU in it and 640kb RAM. My question on these two items is> Are they compatable? If the answer to that question is yes, can, and will, someone give me the jumper settings for jumpers 1,2,3 ? If no, then what kind of adapter card do I need to hook up an IBM model 5153 monitor? I have several old moniter adapter cards. Can I increase the RAM in the DTK PIP-151 past 640kb? If yes, how? If no, thanks. On another subject I took the APOLLO 400 apart and have some numbers to ask about later, after I get to my other house, the one with the classic computers in it. John Amirault
