Out of curiosity and ignorance what's with the solder joints on the cards in the pictures?

Hi all, As an update to this project, I can report that the DELQA has been repaired with four new static RAM chips, and now the MicroVAX II's network is fully working (including netboot). Credit due to Joe Zatarski (joe_z) who did a beautiful job of desoldering and putting sockets in for the four RAM chips. --Toby > > I must be doing something wrong running the test manually, though - > >>>> d/w/p 2000192c 2000 > > Just leaves 2000 in the VAR register, permanently. > > --Toby > > >> >> Noel >> > >

WTB several IMSAI-8080 ON-OFF-ON momentary switches

by Mark＠Misty.com

Hi, Does anyone have any available? I don't need the paddles, just the the ON-OFF-ON momentary switches. I got good ON-OFF address/data ones from Herb Johnson, but the momentary ON-OFF-ON ones I have are worn out and do not return to center properly. Mark -- Mark G. Thomas (Mark at Misty.com), KC3DRE
