    Mac Plus - Identify this Memory Expansion

    I will definately look into one of the emulators that will allow me to build custom .hda images, yes. I do have a floppy emu, its lust wired into the internal FD port of my //c at the moment. I might mess with that also.

    Mac Plus - Identify this Memory Expansion

    Hi BMOW, Yes, agreed. I should have said that I didn't notice any other impact on the system from this card, other than it adding the extra RAM. It didn't require any CP items, or drivers of any kind. Seems to be quite transparent to the system. Memory must have really been quite expensive back...

    Mac Plus - Identify this Memory Expansion

    Yes, I have used a few of those stock images for the ZuluSCSI. But unless I am mistaken, I believe that you cannot just drop a single "program" onto the ZuluSCSI SD card unless its an image of some sort. This would mean that you have to create an image containing that program in an emulator, and...

    Mac Plus - Identify this Memory Expansion

    I am currently looking for an external floppy or HD (Macintosh original, not 3rd party) for the Plus. I have also ordered another 2x 2Mb RAM SIMMS, to put into the system. I might get a total of 4x and do away with the 3rd party RAM expansion. If anybody is a collector and would find value in...

    Mac Plus - Identify this Memory Expansion

    I do have a Floppy Emu, but its currently wired into my //c. I do have a ZuluSCSI, but I am yet to work out if it can do the simple file transfer like the BlueSCSI on which its based. I'm not sure if it can, and I don't want to go to the trouble of creating HD images just for random program...

    Mac Plus - Identify this Memory Expansion

    Yes, the Mac Plus is indeed reporting 2Mb of RAM. There seems to be no other indication of that RAM expansions impact on the system. Seems to work as fast (or slow) as a Plus would. I did work out a way to make a *reasonably* reliable 800k disk from a standard 1.4Mb HD one. As the issue seems to...

    Mac Plus - Identify this Memory Expansion

    Thank you so much for this information. No idea how long I scoured Google Images looking for something that looked even close. Interestingly, the attached Datasheet from @MacOSMonkey says that the installation includes a piezo fan. No such fan was installed in this machine. Once I work out how...

    Mac Plus - Identify this Memory Expansion

    Hi there, First post to this forum. I was wondering if anybody can identify this memory expansion attached to my Macintosh Plus (Macintosh Plus 1Mb). It connects only to the first two SIMM slots on the logic board, and there is a small red jumper attached to two points on the logic board as...
