I just got an 8K PET with the chiclet keyboard...which after 20+ years needs a good cleaning. Most keys workfine, some are intermittent, some don't work. How does one go about cleaning a 20+ year old keyboard? Also...is it easy to replace keytops? Anybody out there with a spare chiclet keyboard? Thanks, Chandra

Wanted: VAX 750 in central NJ

by azog＠azog.org

I recently moved into a new place that has plenty of room, so thinking to myself, what better to get than a VAX 750? So I'm considering looking for a (hopefully working) 750 in central NJ area.

Silly Apple IIc question

Thanks for any clues. >> depends. if you use dos 3.3, you use INIT HELLO from a command line. if you use prodos, you have to run the system utilities disk and choose the relevant option.

Corvus?

by optimus＠canit.se

While going through the manuals for a Stride 460 last night, I finally discovered what the LAN port was for - Omninet (Corvus). I know of exactly one other machine with Omninet- the Research Machines Nimbus. Was this network widespread once? What kind of topology did it employ? Are there NICs for any other computers, perhaps even PCs? Any information is welcome. -- En ligne avec Thor 2.6. The object of this game is to take an ordinary guy and make him into a Pimp Master. You start off in your home town.You'll gradually build up cash and prostitutes,until you wipe out the other pimps in town. Then,it's time to move on to another,bigger city,and do the same. Pimpin' ain't easy, upcoming game from Delsyd Software

Fwd: Naked Mini Broke

by jimw＠agora.rdrop.com

Ok... Just when you've heard everything! This guy could use some help, and while I've got a similar machine in the collection, I've got *zip* information on so probably can't be of much help.

Epson HX-20 has faulty display

by Garrett.Holthaus＠colorado.edu

Hello, I collect old (relatively speaking) computers, and I recently acquired an Epson HX-20 laptop. It worked fine for a while, but now the display has some problems. It looks like maybe the display driver is refreshing the screen improperly--I see a bunch of flickering vertical lines. After the computer has been off for a while, when I turn it on the display works fine for about a minute, and then goes bad. Does anyone know what's wrong with the unit, or where I can get a schematic? Thanks, Garrett

Sparc2...FAILURE: No Trap Taken, Exp Trap Type - 00000009...Solved...simms in wrong banks...now more questions...

by claudew＠videotron.ca

Ok so it was the RAM in the wrong simms sockets. Someone had pulled so simms and what was left (32M) was not in bank starting at 0.... Found out the proper bank scheme in the Sun hardware faq...(lots of reading again...less time with wife and kid....) Now system starts up and tests memory. Reports 48 Megs (added 16 Megs so all normal) but tests just one? Why? So now I can get in the diags and stuff.... But more questions...(maybe ill answer these by myself again...) I have a type5 keyboard and a Mouse Systems Sun Mouse 370-1170-01 But system reports it cant identify the keyboard. I used a MAC/Apple serial cable to connect the kayboard. Leds blink for a second when system turned on but after then I cant toogle the leds on the keyboard keys by pressing the Caps Lock and Scroll Lock etc...keys... What about going a bit further with this? What should I attempt to run on this? You can suppose Ill find 4 more 4M/30pin/parity Simms somewhere here and end up with 64M...(not found yet but looking...) I think 3 chip simms wont work correct? Should I try? Or just hopeless? Also I think the frame buffer is a GX (?) Ill build an adapter for a VGA/SVGA monitor when I find a 3W13 connector somewhere here.... Anyone?

Sun newbie with non-booting Sparc2...FAILURE: No Trap Taken, Exp Trap Type - 00000009 I am reposting this cause I never got it back so I guess it never made it for some reason... Hi Well I found one, I had been asking for one on the list and got no real offers so I went out to this place and found a sun sparc 2 for $20 canadian as-is. I know it not fast but still...its a sun... Looked complete but was very dirty. Cleaned it off now very nice.... Unit is a SunSparc 2 model 147. Had a floppy, HD Maxtor LXT213SY (200 Megs I guess...), and what looks like 8 X Simms of I am not sure how many megs...nothing hacked or missing... Video card (yup one in there) is a Sun Microsystems S4LEGO (?) I tried hooking up a type5 keyboard I had lying around and a Sun mouse...Keyboard leds lite up and power on and I get a beep but after that...cap lock and other leds will not toogle on/off with pressed...so... I did not have a monitor or adapter to connect a monitor to the frame buffer so... After reading for quite a while in the sun faqs I removed the frame buffer and connected a Wyse60 to serial port A and got: (well at least something' coming out of the serial port...) WARNING : Unable to determine keyboard type FAILURE: No Trap Taken, Exp Trap Type - 00000009 I have repaired lots of logic and computer boards for many years at the component level but know close to nothing about Suns...any help appreciated.... If you can tell me more about this, it would be appreciated... This will be much faster getting answers from someone than reading through tons of Sun hardware faqs I guess...

Sun SPARCstation 2

by ajp166＠bellatlantic.net

From: Iggy Drougge <optimus(a)canit.se> >CP/M and DOS don't even have GUIs. =? Yep, saves space and runs like the wind. >The QNX demo is of course interesting, but won't run on a 4 MB machine, since >it is heavily compressed on that floppy and needs to unpack into RAM. So, you want everything? ;) the only thing I know that has a gui and can run in 4mb (barely ) is non-PS (VMS/Decwindows). You still need at least 80mb of disk though. I've heard the Amiga or one of the other commies had a real neat rommed OS that had graphic primitives. Allison
