HP 8594E Replacing the green CRT with LCD

[Miti]

Have you considered making it commercially available, or would you have one or two spare boards that I could purchase from you?

Yes, I have. Unfortunately for awhile most of the parts were not available anywhere on the planet. At this moment they are back in stock except for the central piece, the FPGA. I have 4 boards in total, 2 Ver.1 with FPGA in TQFP144 package and 2 Ver.3 with BGA. Ver.2 was never built, it added a hole for the power pad of the TQFP but then I moved to BGA package. I could make one Ver.1 available but I'll have to port the code from the BGA to the TQFP (I abandoned the TQFP code after I changed the package but this shouldn't be too hard) and test it thoroughly.
PM me to discuss.

And I was wrong. I’ve checked last night and all the boards are running the latest version of software. I thought I stopped updating the one for the TQFP but I have not. If you decide you want one, I’ll prepare the cables, the resistor you need to solder on the main board and some instructions.

Thank you, I'll get a look at it this week and let you know. If it is CRT gone, would love a LCD upgrade for it.
