Looks like all from the same seller - probably a broker.

For Sale/Wanted, Suppliers / Craigslist

I've never used craigslist myself was surprised to notice pick and place machine craigslist listings come up in google results. Currently there are apparent listinga for a Europlacer (or 3 or 4..) one of those nasty little Maddeltechs and a Phillips machine (with an incorrect YOM). A quick browse would shows a considerable amount of kit on there, especially if you like lathes & CNC. Much of it seems to be posted under "London" even when it isn't really.

Ah interesting, OK I'll figure out how much I can increase the stop by and put it up on here. BTW here's the 1st quote I got for the acetal part of the conical nozzles. Actually these can be black acetal, black nylon, or black 30% glass filled nylon (I remember somebody suggested that) for roughly the same price. Actually there's a warning on the GF stuff that it may warp afterwards.

Check the tool change height and the feeder heights too..

the lowest position you are likely to need is when using waffle trays..
and you can pack those up to a reasonable height too.

On both my machines, the z axis has been the source of most trouble  :(
anything you can do to reduce the stress will be good.

>>> RV Setup and Gerber work OK on Win7 for offline setup, only RV Place is hardware-dependent

Interesting, I was having problems with those under Win 7 (64-bit). I even tried something called 'Win XP Mode' which is a sort of virtualised XP under Win 7 (who knew :) ) and it wasn't happy. No problem, just an experiment.

>>> re having to assist the z axis when starting, you may find that the park position is way below any of the z axis heights used during placement. If that is the case, then you could do a quick fix and put a spacer on top of the z axis bottom stop so that it starts from higher up!

I see what you mean, that looks very do-able. Here's a snap of the lowest un-powered position vs the PC supports. Clearly the nozzles can't go much lower that the PCB in practice, but does the fiducial camera need to go lower? If not the end stop could be much higher - by 12mm maybe. I guess it still needs to trigger the bottom sensor.

At the risk of outstaying my welcome, can I ask this - there's a black plate above the head (red circle below) which looks like its just to keep light out and is usually glued to the top of the arm (unstuck in my case). On this machine, it fouls the orange belt a little. Is this normal, should it be thinner?

TIA, Alan

Interesting to see those ISA-USB cards can support multiple ISA cards.. !

re having to assist the z axis when starting, you may find that the park position is way below any of the z axis heights used during placement. If that is the case, then you could do a quick fix and put a spacer on top of the z axis bottom stop so that it starts from higher up!

My Windows 8.1 and windows 10 machines can fully access the HDD on the two windows 95 machines, but not so easy the other way round.

ps,  the end metal cover does seem to help with the image quality on the arm camera on the RV4s but probably less important on the RV1S, so I wouldn't worry about it

Thanks, interesting, then I'm guessing the latest OS that might support the two cards is maybe XP.

BTW I found that this ISD/SATA <-> USB device works well for slurping the contents of old IDE disks to somewhere safer:

"Bipra USB 2.0 to SATA/IDE Adapter Kit with Power Adapter for 2.5/3.5/5.25 inch SATA or IDE Drive"

https://www.amazon.co.uk/gp/product/B001A5SK56/

Interestingly the apps will start under Win 7 - but I have not got them to do all their file access OK yet.

For amusement here is the original Paul Mills patent:

p.s. The apps run apparently OK in Win XP without the same file access issues as Win 7 - this is without trying to access the camera or stepper driver cards.

A long time ago I used a utility called (I think) directIO to run an old ISA card in-circuit emulator under Win2K - Win2K was majorly different in that it no longer allowed applications to directly access I/O memory space.
DirectIO allowed you to specify address ranges that a particular application was allowed to use.
Re. networking - Although modern NASs don't seem to work with Win98, a Win98 machine does appear to be able to access shared files on a Win7 PC, so that's a possible solution, though you don't really want to run jobs over a network share to a Win7 machine that is being used for anything else, in case it falls over mid-job.
I run a batch file on the RV that does a copy-newer-files operation on the job, cdf and .dat files, so the Win7 PC ( which is backed up automatically) has the important stuff should the RV's HD crap  out.
 
A possible option for booting an old PC avoiding a mechanical HD may be  CF card.
