Replacing TDS540B CRT with LCD?

 

I believe that this is possible given a suitable "open-frame" 6.5" monitor
panel (I assume 640*480).

So far I've failed to locate anything on eBay or AliExpress (even at silly
prices).

If anyone has a pointer to a suitable panel (ideally cheap-ish) I'd be
grateful!

Thanks
David

David,

Look at http://simmconnlabscom.ipage.com/store/page5.html pricing is
$229.00USD - I have installed two of these in TDS540C and one, a different
kit , in a HP 8566B and they all work great. The install directions were a
bit ambiguous on what to do with the glass on the glass that was in front of
the CRT. The instructions seemed to indicate leaving it off, I didn't like
that so when I did my scope I modified the frame (very minor) so that the
glass was kept and the result is spectacular

Thank you for the pointer to the simmconnlabs kit.

Unfortunately by the time that crosses the pond and has been processed by UK
Customs that comes to near as darn it 230-250 pounds, which doesn't add up
for me. Part of their cost is an FPGA which I believe I can avoid the need
for by using the VGA port to drive the LCD (though I'd need to add some
VRAM).

Had you considered a VGA LCD panel and a driver for it?  You might buy the whole thing and put it in the appropriate spots.

If you are prepared to to some work yourself as opposed to installing a finished bolt-on-kit I can recommend this:

Hi David,
    how about this one? I believe Hakan managed to fit a 7 inch 800x600 (actually the part number is very similar).
£45 plus import tax...

https://www.ebay.co.uk/itm/LCD-VGA-2AV-Controllers-with-Remote-Control-7inch-800x600-LCD-Display-A070SN01/263388878055?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D60272%26meid%3Db6714bdf1367445ba732eead2db547bf%26pid%3D100005%26rk%3D6%26rkt%3D12%26mehot%3Dpf%26sd%3D253979723396%26itm%3D263388878055%26pmt%3D1%26noa%3D0%26pg%3D2047675&_trksid=p2047675.c100005.m1851

These seem to be popular for car reversing cameras (note the 2 phono sockets in the pictures) ...

I have a couple of monochrome 6xx series scopes that I would like to convert - does anyone have any ideas about converting the mono display to colour? (I think one of the kit suppliers does it using a bit of programmable logic clamped over the DAC area of the PCB...)

From what I understand, for full color you'll need the CPU board changed out from the monochrome version.  Otherwise, you'll need to do some trace cutting perhaps, and that's something I wouldn't want to do without a supply of working CPU boards, if then.....

I think that the kits *may* offer a partial color, but it's not on a per-trace basis.

It's not that hard to convert the board - move a 74F04 (IIRC) and add VRAM

I'd love to have the details, if you please.  I've got a "spare" 540CPU that I could change.  Already have the memory upgrade, I think.

Thank you, however, I have a 540A, and they are using B and above.
