POST YOUR blahblahblah you know the drill

8 inch LCD @ 1024x768, with driver board (HDMI, VGA, AV), USB touchpanel, all wiring, remote, $118 shipped.

When the link above goes out of date, the seller's name is chinatobby2011.

I just purchased one, so I'll let you know how it looks when it gets here.

1024x768 allows you to display an old-mac 512x3xx display at 1:2 pixel-doubled (ie, no rescaling blurries)

CRTs, LCDs, etc. Link, cost, brief description of what makes it useful to us, and thus worth posting here.

Common as dirt LCDs at retail prices that anyone can find at Newegg, Best Buy, Dell etc. will be removed, unless there is something notably and unusually useful about them.

That's a mighty small bezel. Looks very good for hacking.

Hmmm. If the remote speaks Sony IR codes, there's every chance it'll work on 5x/6x00 Macs and the like out of the box...

Heh! A $1.380 multiple device universal remote would make a good backup plan. }🙂

Here's the one I've been pondering:

That's a pretty decent price for 800x600 with free shipping, Trash.

Ebay seller njytouch has been in the DIY LCD kit game for a long time now, and stocks an interesting range of kits, bare LCDs, controller boards, touch overlays, cables, accessories, etc.

Of particular interest (to me anyway) are their programmers, which allow you to flash certain of their driver boards for specific LCD panels resolution/timing etc yourself. These would be handy for testing, and for hacking oddball panels.

Turns out chinatobby also sell programmers for their panel driver boards, and in convenient packages with a programmable board.

They also sell upscalers which convert from CGA/EGA graphics to VGA - these are useful inasmuch as it has been shown elsewhere * that the video from classic boxMacs ** is near enough to EGA for a few diodes and resistors *** to convert and sync to an EGA monitor. Add one of those and viola - VGA.

* somewhere on this forum there's a relevant thread

** 9" b&w all in one 128k --> Classic II, not including Color Classic/CCII

*** or something.

I just had an idea of a Classic II mobo in side a small case with a ROM drive and 1.44MB FDD with a miniATX PSU.

Posted by: MinerAl on 2013-04-10 07:40:27
That would fit in an Apple SC series ZFP drive box... you could use an LC power supply too. 😎

And the RGB versions (with a bit of help again) will connect a VGA monitor to an Apple IIgs.

a miniATX PSU
Better yet:



and an external 12V PS.

I have actually used these in a few low-power noiseless builds I have done for people and they are excellent. If I ever get around to building a MiniITX Macintosh Classic, this would be my only choice.

Just be sure to spring for the 192w 4-pin power supply version, even if you only plan on consuming half that. It will give you ample headroom for extra future components, the AC adaptor will run much cooler and last a lot longer, and the 4 pin plug is less prone to coming loose.

Someplace else here there's a thread about power consumption, and I remember being surprised that the SE/30, with monitor, only pulled about 45W. The CRT has gotta be around half of that, at a wild guess. So, I dunno - 190W seems a bit overkill for a headless one.

Though I do agree with you in general about designing in plenty of headroom.
