It depends on which ROMs they have. Joe

Pink Screen of Death? (was: Re: Hallelujah!)

> > But what kind of computer would a satellite software company have been > > planning to run that program on before they ported it to the real world? > Hal ?? I can imagine some nutty fanatical CS prof (like me) saying, "If you want TRUE platform independence, then IGNORE all realities of the computer; write your program for an imaginary computer that would be perfect for your needs; then map the keyboard, etc. over to the layout that is present on the real world computer." Is that the way that it happened? Or was there some computer that actually HAD those goofy keys? (There were eventually some aftermarket add-on keyboards for the PC for WordPervert.) Please do NOT interpret this as a defence for MSWeird!

IBM Programmed Symbols Adapter

On the > other hand I might be thinking of the Epson QX-10 Valdocs :^)) Like Sam, I think of three cards in this connection, but I also recall that not all machines had all cards. The 3270 card may not have been the same card as the display adaptor... On the display side, there was a display card, which may or may not have been part of the terminal card. Without it, you can't drive the 5272 monitor, I'm afraid. In addition, you could get the All Points Addressable (APA) card, which emulated the CGA graphics modes (but note that the 5272 only displays 8 colours), and the PS card, which you have, which emulated the graphics and programmable character set modes of the 3279 terminal. I'm afraid the card on its own won't be of much use... Philip.

More odd things: HP150

by karlm＠blitzen.canberra.edu.au

Today I dusted off the HP150 I picked up the other week, when I saw it I actually believed it was only a terminal, but it had a HP-IB interface which made me pick it up. Discovering that it is a non-IBM compatable 8088 based machine with a touch-screen was nice :-) Not having any drives with it renders it useless as a computer, but I am interested in getting it working as a touch screen terminal, does anyone have the docs for this? or be able to tell me what "Power-on error 1000" means? and how to test out the touchscreen? Megan: I haven't forgotton about the VSV-11, I have holidays next week so I'll fire it up and see if it still works for you, been a busy fortnight :-) Cheers Karl ------------------------------------------------------------------------------ Karl Maftoum Computer Engineering student at the University of Canberra, Australia Email: k.maftoum(a)student.canberra.edu.au

Four 2901s and a lovely 16bit architecture, and then they go and implement a 6800 on it. :-( :-( :-( Philip.

VERY OT: Win'98 splash screen

by roblwill＠usaor.net

Me, too, but you don't know my dad... He has his computer in the living room, with the screen facing the window, and he says that he wants it to look nice when it's booting (don't_ask)... I think he deleted the spare one, too. I did a search, and can't find it anywhere. Either the computer didn't come with a copy of the CD on the HD, or my dad deleted the copy, because I can't find that, either. I told him he'd be better off to just put DOS back on the thing.... -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1> -----Original Message----- From: Paul Braun <nerdware(a)laidbak.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Tuesday, April 13, 1999 5:26 PM Subject: Re: VERY OT: Win'98 splash screen I'd be thankful.

Description of 11/44 Installed Board Set

by hhacker＠home.com

Mitch: Don't know if I have a printset. I will look into that question. Zane: The comment on storage capacity was intended to come across as sarcastic. Also, as a comment on the size of hard disk drives now being sold. I mean, I saw a 20GB IBM (I believe) for under $350.00US at Fry's last week. William R. Buckey

Well perhaps it is because the de-facto standard DOS wordprocessor was Word Perfect. Their system was default blue screen and white letters. A long long time ago in a system far far away Microsoft was just another software company and they 'adopted' WordPerfect's colors and emulated WP commands. Paul
