Power Supply Upgrade
I have an original 8800 that I built when they first came out. I would like to upgrade the power supply. would you share information on the commercial power supplies you are using in the new kit?

Yes.
One of them is a 7.5v 100W and the other is +5/+15/-15v 60W. Both supplies have a trim screw to raise the voltage of each by 10%. This will bring the voltages into S-100 spec of 8v and 16v. However I've been running my altair on 7.5v and 15v for a while know. Seems to reduce heat quite a bit and not cause any negative operation. Power Factor has several power supplies larger than 100W. The largest is 320W at 7.5v. PLENTY for an S-100 system! :) http://www.power-factor-1st.com/shop...es/s-100f.html http://www.power-factor-1st.com/shop...ries/t-60.html |
It seems the links have changed. The new ones are:
http://www.power-factor-1st.com/g2-series/s-100f.html - S-100F-7.5 http://www.power-factor-1st.com/g2-series/t-60.html - T-60C |
Thanks again, Grant.
My original 8800b had been running for years with 7.6 V actual on the 8 V unregulated lines. |
