Ahh, its probably how the TechStep communicates with these machiens then.

I have not had a chance to try yet

I didnt know about the diagnostic modes, Loving that. However its very cryptic, i wonder if a tool could be made to run those commands for you and then spit out which chip is bad.

Unfortunately the cards are long since EOL, you cannot get the RAM chips anymore, and perhaps even worse, the XC95 series of CPLDs are now slotted for EOL. It has been awhile, but i think the jumper wire goes over to the /AS signal on the ROM header. But dont quote me on that, since ive not...

That actually doesnt look too bad, fairly normal. those CRTs were never that sharp when new.

i missed it too, because its a financial thing for me.

Awesome you were able to use my videos as an educational tool! It is why I do what I do

Yeah exactly! and that was my first attempt. even did a video on it. I went back and ended up redoing it.

Yup, this is why for example with window tinting (similar adhesives) you have to use an applicator fluid, and heat to get it to work along with a squeegie (credit card or etc) to get the bubbles out and work them out while its still semi fluid. or it wont work. There are various formulations...

I just did a toshiba T1000 LCD and ran into the same problem with the bubbles. To fix it, you need an applicator fluid, the type of stuff used for laying down vinyl graphics for large format printing. But you gotta remove the panel away from the backlight assembly, lay it down on a table and...

Thanks for the info on this! They have some 0.8mm ones on ebay so maybe I will try that.

Family vacations arnt something ive been on in decades. VCF basically is my vacation anymore

Imma be there this year for the first time as well, exhibiting with the rest of my friends.

Oooh, I will play! Here is a picture of my WeatherSTAR 4000 I had fully reverse engineered and got running again with my own custom software. This is running a dual-68K setup with a pair of MCS51 CPUs as well, along with a ATMega and a Pi acting as the host. Also a picture of it being displayed...

I have gotten to the point where I replace those chips anymore. They easily get damaged from the capacitor leakage. UE8 is mandatory, and the rest are secondary. Also I have found that sometimes the VRAM itself gets damaged on the data bit outputs and its missing a bit. From the look of the...

I have his prototype which works perfectly fine: I didn't use the ROM slot /AS jumper, thats required to see more than 5MB of RAM:

Basic system software doesnt support that amount of RAM or it will crash. This is normal. You have to have a full install, for the portable install in order for the system software to not crash on About this Macintosh. Also, the wire is there to connect to the ROM slot /AS when using it on a...

Yeah hopefully we can figure it out. You were able to simplify the logic versus my design.

I think Maceffects quit selling that version because of 2 problems. One, you cannot get the CPLDs anymore. and thats the thing pinching BMOW and his decision to potentially discontinue the Floppy Emu. and two, the RAM ICs probably ran out, which is sad :-( I have a dynamic engineering RAM card...
