new pickup! an NEC MultiSync (the original) it is very dirty š
made in 1986!
on the left is the my existing monitor with the stand i 3D printed. i made the design with only a few grainy pictures of the real stand for reference. not too shabby!
picked up this absolute beast of a hard drive. this is the Maxtor XT-2190! it stores 160MB when formatted. this was huge for 1987.
it's got 4 defects. they give you those numbers on the label because you have to manually enter them when you low-level format it!
I'm not sure it's working because the drive's logic board isn't screwed down. and it's missing the insulating spacer so it can just short out against the metal case š
i've been thinking about digital counters for state machines lately. probably because of the interesting counter design that i found in the IBM CGA card (schematic below). š§µ
but back to a basic digital counter. it's simple, right? you just count up in binary. 000->001->010->011->etc. but there are some disadvantages of doing it this way.
in digital logic, be it in an FPGA or discrete TTL chips, the basic idea of a design using synchronous logic is that you have flip flops that store your "current state" and then combinational logic that take the current state and generate the "next state".
