Power Supply restoration for Xerox Star 8010 and PILOT OS needed

by nick.allen＠comcast.net

Hey everyone, I recently acquired a Xerox Star 8010, I now have panels for it (Thanks Jason Timmons) and am now working on the power supply. It is missing the transformer, does anyone have documentation on the power supply? I know it outputs 5v/12v and therefore I am looking at a 8v/16v transformer. Any recommendations on AMPS? I can find a 20A/30A transformer or a 80A/120A transformer, any suggestions? Also, anyone have a digital version of PILOT (the OS for the Xerox Star) or know where I can get a copy? Thanks! Nick

Q-bus chips

by useddec＠gmail.com

A while ago someone was looking for various Q-bus chips. I don't remember who or what the chips were. If there are usable chips on the DEC M8044, I have 25+ of them that the chips could be removed. If anyone one is interested, please contact me off list with an offer. I can knock off a few bucks per board if you don't want the fingers. shipping is from Illinois, 61853. I'm still clearing out items, trying to make pathways. Thanks, Paul

Dell Unix

I was going through some old emails earlier, and came across one with a brief blurb about Dell Unix, along with this blog post. http://technologists.com/notes/2008/01/10/a-brief-history-of-dell-unix/ Has anyone worked with Dell Unix on this list? Any thoughts or comments? Jerry

LA180 / DecWriter I

by quapla＠xs4all.nl

Hi, After being kept in a corner, I unearthed my LA180 aka DecWriter I. After powering it up, no magic smore, but some humming from the fan. The selftest went ok, but the ribben needs replacement, the characters were faint. Now, I want to hook it up, so I opened the backpanel to locate the serial line, only to find out is is not having the converter board which is an LAXX-NY for EIA signals according to the user guide. So, is there someone having this board and is willing to sell it? Thanks, Ed -- Dit is een HTML vrije email / This is an HTML free email. Zeg NEE tegen de 'slimme' meter.

Did you say it was from Svensk Text AB? The name rings a bell, but they do not seem to exist any longer. /Jonas

We currently buy delay lines from Rhombus. They have limited stock of many items for prototyping and repairs. Digi-Key has a wide range of pulse transformers from about 5 manufacturers. If the transformers are 1:1 winding ratio, there should be a huge range of parts available, and the exact inductance may not be very important. Jon

Why not sell overseas?

by alexandre.tabajara＠gmail.com

I'm very sad with the way things are going... I tried to buy a swivel base for my eMac, and NO ONE of the three or four sellers accept shipping to Brazil, nor sending for some friend in USA to repack and send me. What is going on? :o( --- Enviado do meu Motorola PT550 Meu site: http://www.tabalabs.com.br
