My Macintosh Plus had the original 1MB of RAM when I got it.
I worked for a printer/publisher back in the eighties. I did some word processing and database work, as well as some desktop publishing on a similar Macintosh. Back then, the original prices for this equipment was very high. A Macintosh Plus with just the internal 800K diskette drive, would have gone for around $2600 dollars, which would be just around $5500 in today’s money.
You could get and use an ImageWriter or ImageWriter II dot matrix printer for use on the Macintosh, but the print quality would not be the best. When the LaserWriter printer came out, you could get what was then astounding quality, at 300 DPI. The big problem with that was the very high list price of just under $7000 in 1985, adjusted to 2015, roughly around $15,500. Apple had addressed this by building networking abilities into the Macintosh, so several people could share this expensive hardware.
When I got my Macintosh SE, it had an internal hard drive, which I wanted to be able to share with my Macintosh Plus. I only had an ImageWriter II printer which I use with my Apple II’s, but I wanted to share it with my Macintosh computers. That meant I had to look into networking the Macintosh computers.
For months, I looked on the internet for details on networking the Macintosh computers. I was able to find very little.
I did find some notes that said in order to share files or hard drives, you needed System 7 or higher. System 7 wants more than 1MB RAM, which is why I wanted to upgrade to 4MB.
I still didn’t have all the information or hardware to network my Macintosh computers, but did have enough information to look into upgrading the memory in one or both as noted in earlier posts.
