 sure enough, the machine chimes, but the video is blank. but i think i know what the problem is. sure enough, there's no PRAM battery. these machines need that battery or you won't get video! i'm going to create a SCSI disk image for my SCSI2SD using BasiliskII and the instructions at https://www.savagetaylor.com/2019/12/19/how-ive-setup-the-scsi2sd-that-i-use-in-my-lc-475/ @tubetime As a new hire at Apple I authored the 7.5 installer script. I moved on to doing software engineering on the OS by 7.5.3, but that always gives me a nice feeling to see it still running.   @tubetime I like to think you have a stock room full of capacitors.  @tubetime I recapped my SNES a few months ago to protect it. Unfortunately I think it has some problems with one of the ICs. Graphics are all weird. Also replaced the vreg even though the output from that looked fine.  @tubetime Seeing this is dredging up ancient memories of playing with not-new SCSI gear as a kid… staring at the baroque arrangement of peripherals, utterly confused as to why it wouldn’t just WORK. @tubetime Memories of SE30s, Classics and a few Quadras in a graphics shop I worked at in 92. I used Filemaker Pro to manage work flow and create job tickets. Great relational database program. @tubetime Oooh that looks fun. Alas all I have in the classic mac world is a Mac SE with no slots. @tubetime @tubetime Yeah I've had mixed results with the SCSI2SD and random old hardware. A particularly weird one is suddenly the same one I've had forever stopped working on my Microvax. Used to work, now doesn't, no explanation.  @tubetime Never even crossed my mind that this was even a thing… 😮🥳  @tubetime @tubetime TIL modern 9v batteries use 3x 1/2 AA 3v cells and not 6x AAAA 1.5v cells anymore! @w4www_raker only the energizer lithium ones, the others use the weird thin stacked cells thing @tubetime @tubetime Thanks for this hint – my LC475 is working again now using the MacBatt PCB which replaces the lithium battery with a CR2032 coin cell https://www.tindie.com/products/siliconinsider/macbatt-cr2032-pram-apple-macintosh-battery/  |
anyway, let's try and get this machine running. i have a funny feeling the video isn't going to work right...
