dylan4397 Posted October 30, 2020 Report Share Posted October 30, 2020 (edited) Hello, I recently got my Macintosh Classic up and running. It had some system issues, but that isn't what this is about. So one day, about a month ago (before I resolved the system issue with the help of people on this forum) I took the computer off of my shelf and it wouldn't boot. It gave me some error messages and when I removed the RAM it booted again. Now with the machine running, the 1MB of onboard RAM is not enough to do anything. I tried using the expansions card without the SIMMs installed. I switched the jumper as well, and it still didn't work. Does anyone know if there is a solution? Thanks, Dylan Edited October 30, 2020 by dylan4397 Quote Link to post Share on other sites
rplacd Posted October 30, 2020 Report Share Posted October 30, 2020 Two things come to mind – first, what error messages do you get? A Sad Mac screen will have an error code that might tell us something. Second, I notice the shunt on the expansion card is on "SIMM NOT INSTALLED" – what happens when you move it to "SIMM INSTALLED", with the extra RAM in, and try to boot? What happens without the extra SIMMs? Quote Link to post Share on other sites
dylan4397 Posted October 30, 2020 Author Report Share Posted October 30, 2020 (edited) The error message is 00000005 00100000 with the SIMMs installed and setting on SIMMs installed. If I remove the SIMMs, I get a white and black bar screen, as you can see in the photo. And as you can see in the second photo, I get this vertical rolling image when leave it set as SIMM installed, but remove the SIMMs Thanks, Dylan Edited October 30, 2020 by dylan4397 Quote Link to post Share on other sites
bibilit Posted October 30, 2020 Report Share Posted October 30, 2020 (edited) Sorry, but don't understand your answer. What's happening with the card card only (so without any stick of ram) and jumper moved to " simm not installed" ? You have got 1 Mb of Ram onboard, the card only will give you another 1 Mb (when jumper set correctly) then the card plus sticks a maximum of 3 Mb. So card alone and jumper "not installed" 1 Mb Card + sticks and jumper "simm installed" 1 Mb + whatever is present. Edited October 30, 2020 by bibilit Quote Link to post Share on other sites
dylan4397 Posted October 30, 2020 Author Report Share Posted October 30, 2020 Yeah, I did make that a little confusing. With the SIMMs not installed and jumper set to SIMM not installed, I get the white and black bars that I attached to my last reply. Thanks, Dylan Quote Link to post Share on other sites
bibilit Posted October 30, 2020 Report Share Posted October 30, 2020 So probably the card itself is bad. Quote Link to post Share on other sites
dylan4397 Posted October 30, 2020 Author Report Share Posted October 30, 2020 Ok, that is what I was thinking, but I just wanted to see if maybe that was a common thing with these cards. Thanks for the help! Dylan Quote Link to post Share on other sites

dylan4397 Posted October 31, 2020 Author Report Share Posted October 31, 2020 Can you really do much with only 1mb of RAM? The only things I could open were simple games like Tetris. I wanted to use Word and programs like that with the computer, but no such luck. Thanks, Dylan Quote Link to post Share on other sites
MrFahrenheit Posted October 31, 2020 Report Share Posted October 31, 2020 You can certainly make do with only 1MB. I did for 3 years!! If you use a minimal System 6 install and something like Microsoft Word 3 it will work just fine. Heck I did SuperPaint, HyperCard, and all kinds of games on mine with just 1MB of System ram.

dylan4397 Posted October 31, 2020 Author Report Share Posted October 31, 2020 Ok thanks for the info! I checked and the version of word I have is 4.0, so I will just find some older versions of the software I have. Thanks, Dylan Quote Link to post Share on other sites
MrFahrenheit Posted October 31, 2020 Report Share Posted October 31, 2020 Word 4.0 requires 512KB, so should work comfortably within 1MB. Quote Link to post Share on other sites
dylan4397 Posted October 31, 2020 Author Report Share Posted October 31, 2020 Sounds good! I do have another possibly big question, that I should maybe start another discussion for. I am trying to use an ImageWriter ii with the Macintosh. I think that they were used together at one point, because I pick both of them up from the same guy. But anyways, I cannot get it to print. I looked up the different settings for the DIP switches, and tried to set it accordingly. I also think that I have the proper system files installed for the printer. They are ImageWriter, ImageWrite LQ, LaserWriter, etc. But no ImageWriter ii. Are the ImageWriter and ImageWriter ii system files the same? I will attach photos of what I have going on. I did get the self test on the printer to work, so I know it at least sort of works. Thanks for the help, Dylan Quote Link to post Share on other sites

Yours boots if you remove the expansion card? Quote Link to post Share on other sites
dylan4397 Posted November 2, 2020 Author Report Share Posted November 2, 2020 Yep, boots fine without the RAM expansion card installed. Quote Link to post Share on other sites
