I can confirm that the code is indeed matching a HD44780 (16x4). BTW: It defines 8 custom characters (the up/down/up-down arrow, Apple Logos, etc). So, that should make things easier for you
I love how sharp and clear these newer displays are, I'm thinking about putting one in some or all of my current TechSteps.I have confirmed modern LCD's with the HD44780 compatible controllers do work fine on the techstep
I thought I had posted that in this thread but I guess not... Must have only mentioned it in PM's with @jajan547
Here is the techstep working with a modern backlit LCD (Which looks much better than the original LCD!)

Thanks I'm very happy with how it has come out and was certainly not expecting it to boot on the first try!Whoa, good job ! You are a machine
Thanks Case will probably be something 3d printed but we haven't really decided yet, this may not even be the final form factor as this design was mainly done to be easy to testLooks great. What are the plans for the case?
I need to get better at updating these threads....Actually me too! And would even love a kit!
It’s possible but would require a good bit of work and testing to reach a stable usable image. I agree would be very cool to see a 5th. It’s too bad Apple killed it shortly after the color classic and LC520Do 68040 based machines have a Test Manager mode? Would it theoretically be possible to make a 5th ROM pack for testing Quadras and Centrises?
It’s a work in progress @max1zzz has updated the PCBs and sold the first few prototypes. This is a great tool for testing Vias, sound chips, scsi interface, cpu, and rom status, and even voltage. Works the same as a TechStep normally would except you select which rom variant through DIP switches. there are four ROM that each Cover a range of certain computers.So…where can I learn how to use this, and what is it useful for?
