> From:?Johnny Billquist <bqt at softjar.se> > All I can add about operating systems related to the original question is that unless I remember wrong, CTS-300 and CTS-500 were based on RSTS/E (basically RSTS/E and hardware bundled together as a complete solution). I think that CTS-300 ran on RT-11, and CTS-500 ran on RSTS/E. You could not compile a Dibol program on CTS-300 without shutting down the main application. On CTS-500 it was easy to compile and debug online. -- Michael Thompson

OT: Can someone help me pick out a desktop machine?

by alhartman＠yahoo.com

A lot of you seem to be missing that he has a store credit with a particular store. He doesn't have the ability to buy a refurbed Leonovo or to build a system from scratch. He has to choose from within the store's available inventory. So, none of the suggestions that don't take into account what the store has in stock, isn't all that helpful it seems to me. Al

Help to format diskettes for At&t 3b1 or Altos systems in a PC

If you log in with the user "install" and blank password, it should put you in the office program. If it's not present, then you need to load the system disks onto the system. Altos - This is a CP/M and or MP/M system depending on your needs; Dave Dunfield's 22disk should work to make a boot disk. If you need more help, contact me directly and I will try to assist, I have both systems. Bill

Usb typewriter (RS-232)

by swtpc6800＠comcast.net

Someone was asking for a RS-232 typewriter. I had one in 1978. I recently found the negatives for photos of my SWTPC 6800 computer complete with an IBM 2741 style Selectric printing terminal. It was used for letter quality printing but it did have two way communication with my computer. I had to write I/O drivers that converted ASCII to IBM Correspondence Code. I could also use it over a 134.5 baud modem connection to a PDP11/70 timeshare system. I uploaded a picture to the Wikipedia Commons. http://commons.wikimedia.org/wiki/File:Michael_Holley_Computer_1978_NWCN.jpg Here is a write up I did for the Northwest Computer News in July 1978. http://commons.wikimedia.org/wiki/File:Northwest_Computer_News_July_1978.jpg Michael Holley

SUN Ultra 5 NVRAM

by teoz＠neo.rr.com

I fired up my Sun Ultra 5 the other day to install a bigger SCSI HD and noticed its NVRAM is dead (FF for ethernet address, serial number changes each reboot). Anybody know a source of cheap replacement NVRAM chips (can they be reworked like a Dallas RTC chip?), and how do you reprogram them?

OTOH I keep all of my images compressed, precisely because I want to know if any copy has been corrupted. (And I md5sum them as well out of FUD). If I find out that any storage media or storage bus is silently corrupting my data without error messages... I would rather know that sooner than later. Tim.

Strange Versatec Plotter question

by healyzh＠aracnet.com

A very long time ago, I used to support three Versatec plotters. We'd have to use a clear liquid to clean them up. It wasn't Isopropyl Alcohol. Does anyone happen to know what it might have been?
