Looking for a photo of an expanded Commodore REU
by Joseph Giliberti 23 Aug '24

23 Aug '24

Hey Everyone, I have a Commodore REU 1750 that I'm planning on expanding to 2 MB. I already have the parts, but I was wondering if anyone has one that is already expanded who can take a photo of what the finished circuit board looks like with all of these stacked memory chips. I just want to get an idea as to what it's supposed to look like in the end. Thanks in advance! Joe Giliberti

> Ah yes, good old Herb has photos... Yup, that must be my IMSAI he was > cracking on! - William Sudbrink Thank you. I don't show photos of the IMSAI. That was end-of-June 2012 so I can't immediately check that photo archive. Felsenstein should be regarded as first among equals in early 70's personal computing. Many people contributed to the works of those times, first-to's are not simple to assign. Beyond engineering and programming, some of these pioneers were social activists. They saw personal technology as media, the means to equalize information-power among ordinary people. Do we have it now? We (the persons at the 2012 event) were doing significant restorative work at the time. Twelve years later, it's commonplace on the Web. I'm surprised how often people find my Web pages anyway. Content is still king, but endurance matters too. - regards Herb -- Herbert R.
