Apple IIe - LCD screen displays only B&W

Submitted by gmontag451 on May 30, 2019 - 11:45pm

My Apple IIe works in color with my HD TV,  but I can't tie up the family room with projects, so I dug out an old Philips PD9012 NTSC/PAL car DVD player which has a second detachable screen. The second screen displays color when connected to the DVD player.But when connected to the Apple IIe, this second screen only displays black & white, as well as incorrect aspect ratio. Is there a way to get color out of this particular device? (I'd be interested in correcting the aspect ratio, but I'm less concerned with that.)Thanks for any advice!

I Found what looks like an IWM Disk II Controller Prototype on eBay.

Submitted by jwg1962 on May 28, 2019 - 4:06pm

Hi Everyone,  

 

I just wanted to share what I found mixed in with a bunch of blank prototype boards.  It's not the Disk II IWM card. At least not the one I have seen a photo of. This does almost look like a mirror image of that card.  It says "AIIE Controller"  deosn't have a part number, so I am guessing this was some kind of prototype card that never was.  I have a collection of blank PCBs from Apple, but not one like this until now.    

 

If anyone here on AF has any more info about it, let me know.  I am going to post it on facebook too.

[IIe Platinum] Getting started?

Submitted by seanephram on May 27, 2019 - 9:49pm

Hey all, 

 

Newcomer here. Do we have a section for getting started?

 

I've just acquired a IIe platinum with a 655-0101 (Uni/Duo) disk controller and an 80COL/64k expansion card (quite the find!) and while I am already having a blast typing up little programs and games in AppleSoft BASIC as my dad used to, I'm here for any and all suggestion on anything and everything a seasoned fan would have on their to do list.

A new IIgs 4MB RAM card?

Submitted by freitz on May 27, 2019 - 8:26am

During a recent browse on eBay I stumbled upon a 4MB RAM card for the IIgs I was unaware of: The GW4201A by a company called Garret's Workshop.

Has anyone bought this card? The price of $35 is very interesting, compared to the $60+ for similar cards.

Apple 3.5 inch Unidisk Drive Analog Card Schematic/Repair Advice?

Submitted by DistantStar001 on May 18, 2019 - 11:20pm

So I have two Apple 3.5 inch Unidisk drives. One works fine, but the eject motor doesn't push the disc out all the way, but I can live with that. The other won't work at all. When I connect it to my //e, and inert a boot disc, the light flashes, then nothing. I've tracked the issue to the analog card in the drive, as when I swapped the drive itself between the two, the failure remained with the defective board.

designspark

Submitted by Gary C on May 18, 2019 - 11:41am

Out of interest, does anyone have a link to a PCB layout for designspark (or other KiCad maybe) for an Apple II card ?

 

Suprising, but I cant find one to download, so will have to make one from scratch, but im sure someone has done it before and would appreciate saving the work if its not too cheeky :)
