      It was Ian and Bill Deg. who tested the MARK-8. After a visual inspection, they pulled the fuses and tested the supply which was perfect, no ripple and the put them back in and turned on the unit. No explosions or fires... A major accomplishment for a machine that is older than "Star Wars" and maybe "JAWS".

      Next up, both Bill and I have to brush up on our 8008 and MARK-8 checkout procedures and do a memory test and stuff.

      Great work for Bill and Ian who both have a giant set of "spherical objects" aka Balls for just attempting a power up after a quick visual inspection and power supply test!!!

We put aside certain items for the club's collection, including an Apple III, multiple Franklins, a couple of Epson and Tandy laptops, various books/software, etc.
      > As always, in addition to working on their personal systems, MARCHins also worked on club-owned systems. The highlight was Dave R. and Matt W. working on our PDP-11/44. They got it working! It booked from one of Matt's own drives; there are a few loose ends with our drives. But at minimum we can demo connecting to the 44 from a terminal and examining memory. So we decided to put it into the museum and move the 11/20 into storage; it's good to change exhibits once in a while. See picture: http://www.snarc.net/44.jpg ... one of the next steps is to swap the yellow surround on the computer itself for a better-looking one from our other 44. We'll also probably swap some of the yellowed drives for different ones.
      > There was plenty of other work on club systems. Some examples (sorry to those that I forgot): Bill Deg. and (I forget who else) found that the Mark-8 seems to work, although we all need to learn more about it; Doug made new boot disks and new Valdocs disks for the Epson QX-10, while Ian P. gave me some cleaning tips for that system's case. Ian did quite a lot -- he also evaluated our Xerox 860 -- it shows a graphical Xerox logo on boot and then looks for disks that we don't have, so he'll try to make some; he also showed me how to open and swap some parts in DEC Rainbow monitors -- the one in the museum had some screen rot; now it's got a clean CRT from a different monitor. Jeff B. worked on two of our Educator 64s, with help from Bill Deg and Ian.
