They range from ingenious to ludicrous. All are interesting. I suppose that could be done with a disembowled Mac, but Apple doesn't sell motherboards so it requires cannibalization of a complete machine.

Most of the software needed updated, anyway. The equipment being tested had the newer IEEE-488 implementation, and the old system couldn't make use of it. We had five of them and the cal lab could barely keep two running. There were days we had to forcible take the only working unit away from engineering to ship on time. After the new software was ready, they bought a pile of NI boards for the Win 95 computers used in test and engineering.

I have a new, old-stock printer for the HP85, still in it's bag and box. Is there any interest in it or is it junk? Some many years ago now, I organized a group purchase from PIC of drive belts for the printer and also developed a technique for re-rubbering the capstan roller in the tape drive. I would appreciate getting your printer ![]() Regards, Michael msg _at_ cybertheque _dot_ org |

Some many years ago now, I organized a group purchase from PIC of drive belts for the printer and also developed a technique for re-rubbering the capstan roller in the tape drive. I would appreciate getting your printer ![]() That was the problem with much of the HP mechanical hardware. The rubber composition just didn't last and would eventually decompose into a sticky mess. For example, this is my reconstructed HP-65 mag stripe reader drive wheel using a slice of clear vinyl tubing. http://802.11junk.com/jeffl/pics/hp65/slides/Hp65-Drive-Roller.html Incidentally, the most difficult part of this exercise was neatly cutting the hose to size. I had to use a razor blade or a scalpel. The tape drive roller in the HP85 was susceptible to the same rubber deterioration. http://www.series80.org/Articles/capstan-repair.html I fixed two using the same clear vinyl tubing trick.

One may be surprised at the current level of interest in HP85 hardware; many are still running well in their roles as experiment controllers and with spares there is little impetus to replace them.
