Dang! I still can do it! G
My R2E4 refused to enter the local editor today.
I could type commands, and see them executed on the main console screen, but NADA on my terminal. (Well... THAT's not right!) I have schematics for an earlier machine, and as far as I can tell, those seem to be the only ones still available. So, trouble-shooting started with finding out that the RS232 ports DON'T come out the EAF board like they used to. I finally tracked the failing port to the BSP board. This sucker has 121 ICs on it, and is the typical "big board" product of the '80s. 1488 output driver... that has to be it. I _actually_ had one in my junk box, but swapping it gave nothing (it was socketed, so no big deal). Checked the input to it while streaming data. No toggle. Checked the output of the UART that drives it -- TOGGLE! Dang! I finally tracked it down to a broken feedthrough on the board. I installed the traditional "patch jumper" made of wire-wrap wire, and it worked. Dang! After over 20 years off-duty, I can still do it. Now I have to find a 20-year-old woman, and see if I can still do THAT! LLoyd |

After over 20 years off-duty, I can still do it. Well, its days are numbered. How many OTHER bad feedthroughs are lurking in there? Geez, if all the chips are socketed, it is a miracle it still works at all. Most of this old stuff, the MTBF starts to head down faster and faster. I had an Allen-Bradley 7320 control that started to have a lot of failures, and I was SURE glad to retrofit it with something more maintainable. Jon |

: What sort of stuff do you make Lloyd? ....tools and machinery for manufacturing fireworks. Much of what I do is simple spindle turning work, but one of the things the CNC machine excels at is doing simple profiled spindles with the work in the mill's spindle and the tools hard-mounted to the table. Another thing for which the machine is indispensible is drilling and boring "cavity plates" for pressing work. When one must drill (on accurate centers) and bore 144 holes in a plate, and have them all align well with 144 pins in another plate, not much else will do. What is a three day job by hand (and always seems to have one "misfit" pin) is about a two hour job on the R2E4. LLoyd |

They aren't socketed. The 1488 and 1489 RS232 transmitter and receiver chips were socketed, obviously after the fact, by an astute technician. They take most of the external abuse the machine could ever suffer. Yes, certainly. I agree that this machine needs a retro-fit, I'm just too busy actually making chips to take it down for now. It's quite reliable. Well, been there, done that, and my A-B 7320 might have been a bit older, but not much more than the R2E4. It did have a massive array of Elco Varilock pins that hooked up everything on the front panel, and I had to mess a whole bunch with those any time I opened the thing up for any work inside. But, I had 3 component failures in about 9 months. The A-B 7320 was really well built, too, so it was not poor design, just component wearout. It probably had been on for 20 years in its former life.
