Actually I have quit a few spare parts from 3 Lotem 800V2 I took apart so as to have spare parts for my own machine. PM me if you want anything specific.

Please describe the lines (thickness, spacing etc.). are they caused by laser exposure or lack of it. Try changing drum rotation speeds and laser intensities. Also, write the cat. numbers of the original TSP card and the replacement. BTW, where about are you located?

Take out the Interlock Board and check if it has burn (short-circuit) marks. It happened to us a few years ago, the burnt item was replaced and the Lotem was fixed.

Did you try to replace the Interlock Board? Concerning your 2nd Lotem - I am not a trained technician but AFAIK, if a spare TSP board has the same type of connector, it should work. However, I would start by unplugging the TSP board and cleaning the connectors.

Regarding power not reaching the Lbox - try replacing the Interlock Board located in the Distribution Box. See the diagram on page 4 of the attached file, Concerning the problem in your 2nd Lotem - after restarting both the Brisque and the Lotem, do you get the same error again?

I wonder why isn't it more popular to Virtualize older computers, with all their existing, comfortably interoperable, legally licensed software. Virtual Machines generally work very well on modern computers under modern OS's. IMHO many smaller firms and independent users don't really need...

When our Lotem 800 reported a Local board error we were advised to switch positions with the other Local board.

Thank you Magnus. You are correct, plotting 1 bit files is no problem for Brisque with TSP, we do it regularly for files ripp'ed on modern third party rips (HQ, StudioRip) as well as files done in Photoshop and sometimes, rarely nowadays, CopyDot files we scan from separated films. Thus, we are...

This makes me wonder, are Dolev, Lotem and EverSmart machines still used in production?

I admit that up-keeping my ancient equipment is a challenge. Recently it became even harder since Kodak refused giving me even minimal support - not even (paid) technical advice. Seems to me Kodak wishes that all their old equipment will be junked. Well, this oldtimer (me) has other plans.

Scitex/Creo/Kodak Oldtimers may still remember and help: I wish to convert a Brisque "Express" (IBM 7029-6E3 computer, AIX 5.1, Brisque s/w ver. 5.1.32) that formerly drove a Lotem800II Quantum, to drive our Lotem 800V2 (Diodes). I shall use "Output Device Handling" to communicate with Lotem...

It may be a good idea to include in your drawing a square with known/marked dimensions such as 100x100 mm. This will help assuring that dimensions were converted correctly.

Once, in the mid 70's, we received a thick bunch of pages to photograph and produce offset plates for a book. The text was ran on Phototypesetting paper and there were a huge number of corrections, single words and lines that were typeset separately and stuck on top of the original job. The...

That machine was considered real "High End". I did send out for that service when we needed higher quality with thin, even coverage of wax. Especially for waxing Stripping Film, when we had to place many small street names on city maps etc.

This waxer was great for use on the back of the Agfa-Gevaert Copyproof photo papers. Kodak had similar Diffusion Transfer materials family named PMT (Photo Mechanical Transfer).

The smell of melting wax had its' fans......
