PDP-8 questions

Not sure how separate classicmp pdp8 readers are from alt.sys.pdp8/pdp8-lovers readers so trying here also. Nothing new if you saw it previously. Does anyone have 4k BASIC or Spacewar? Poly BASIC, DECUS 8-195 seems to be 4k. I think Edusystem 10/15 BASIC also ran in 4k. I think there also was a 4k Poly Spacewar. I have this one which is 4k but it doesn't have gravity etc. / SPACE WAR / / INTERPLANETARY DEATH AND DESTRUCTION ON YOUR / LAB-8 / / EVAN SUITS My desktop straight 8 is missing the wood side panels so I want to make some. I took pictures and measurements of MARCH's but I can't remember if they were real wood veneer or imitation laminate. Does anybody know more or can look closely at their's? Online seems to think it was rosewood but doesn't say if it was real wood. One reply on pdp8-lovers said the desktop panels were imitation and another said the rackmount were real. Did current stright 8 owners do margin checks and if so what margins are reasonable to shoot for? The manual doesn't seem to clearly say. The last is the DF32 with the straight 8 has modified W103 device selectors. It seems that they were modified from pulse amp outputs to DC coupled level outputs. Has anyone seen this done before? http://www.pdp8online.com/dfds32/pics/w103-mod.shtml?small (next picture is schematic). I'm still working on getting the drive running so haven't seen if they work ok.
