As noted by iFixit, the first-generation Mac sported an 8 megahertz Motorola 68000 processor, 128 kilobytes of DRAM, 400 kilobytes of total storage --?on a 3.5-inch floppy disk --?and a 9-inch, 512 pixel by 342 pixel black and white CRT. The beige box sold at retail for $2,495 --?$5,594 today.
Input and output capability came in the form of then-high speed serial ports. Both the roller ball mouse --?which was notable for its relative lack of electronics --?and mechanical keyboard connected via bulky DE-9 plugs.
iFixit awarded the Macintosh 128k a 7 out of 10 repairability score, though the crew made no mention of which decade the score applied to --?some components, presumably, being easier to acquire in 1984. They dinged the machine for its soldered-on RAM and lack of internal expandability, as well as the possibility of a high-voltage electric shock from the display.
The computer was loaned to iFixit by The Vintage Mac Museum, a private collection of Apple computers and memorabilia run by historian Adam Rosen.
