Thanks! Funny thing is I finally got it to work and even made a working D4M image that I was about to upload!

Anyone get this to work? I have the FD roms and have attached to VICE 2.4.... However I can't create a d@M or D4M image, it errors out. I tried using DirMaster to create a D2M and it doesn't work either (0 block). If I try to format it I get a write protect on error.

Well I'll order one and give it a shot. I've got all the pieces parts off of ebay so I'm sorted.

now if I could only find a 2.88 drive.

I've got all the pieces and parts SANS the 2.88 floppy itself. Unfortunately the only ones I seem to find are IBM units missing the power adapter and are apparently powered via the 34 pin cable. http://tinyurl.com/chcotzf
I'm wondering if I solder on a MOLEX connector if it would work?
I cracked my FD2000 open. It looks exactly like the one pictured earlier in this thread IMG_9850.JPG. It's a REV1E with 2086 in the "white box" area. Unfortunately it doesn't have the emply floppy controller socket pre-installed. I do have an ED disk and blank floppies. Will have to try this conversion but I'll need to get the FD4000 bin file.
Quite interesting, there is indeed no red in it, though I do "see" it. Interestingly I zoomed the hell out of it and there are grey dithered blocks that even at maximum zoom individual pixels though grey do seem to have a rouge hue to them.
Now I surmise that the reason we see red is because of what we're looking at! A monitor, which uses a mixture of RGB to make the colors, thus there are no doubt (well in my feeble mind at least) that there are in fact some red "dots" on an LCD and in the CRT there is some light from the red gun that's generating the gray tone. The Darker gray's have more of the "other colors" in it so perhaps that's why the grey-scale doesn't appear to have any red.
Time to call my eye doc!
How do I get into 50 column mode with ZED? Also the brown looks brown, in fact all the colors look much richer than they do with my non Video DAC system that I currently use with VGA (I haven't tried my DAC solution yet other than to make sure it worked once).
I need that BASIC program to show all the colors....
As an FYI I am using a component / Svideo 80 column adapter made by MyTec (makers of Read Admiral and ThunderDrive). It works great! I got this as the 3 LCD's I have that are 4:3 aspect ratio don't have VGA inputs. Colors are true, text is clear. He (Admiral Decker) sells them for $119 for anyone interested. It's the whole kit and kaboodle assembled with nothing else required. I can post pics for anyone interested.
EDIT: He also makes them for VGA, though I'm not sure of the price on those.
No joke. I removed the chips and have replacements on order. I did assemble my second board and it works just fine. But now I have a new problem, the recent batch of LCD's I got (13" 4:3 aspect ratio) don't have VGA input. Only svideo/component/composite. BOO! So it would seem I need yet another adapter to convert the VGA to svid or component, or perhaps something completely different from the 8220 to convert CGA to svideo.
Oh, and I get to repair the other board because when cleaning up the solder after removing the chips I lifted one pad. Not my week I guess.
UGH! Silly silly me.
SO I finally assembled mine today and guess what, I wasn't paying attention and incorrectly assumed the GBS8220 output for the power was 5VDC. Needless to say the chips on the DAC released their magic smoke when the 12VDC was passed through to them. Time to order some replacement chips..... /sigh
so I got the PETVET installed and viola my PET 2001-8 now is running BASIC 4 with 32K RAM. I appear to have a dead keyboard (mostly) Interestingly the problem of the video going out and just showing some vertical lines which eventually fade still pops up. However, simply tapping the screen makes it come back. Very bizzare. The only keys that work are:
4 7 8 6 . \ / 2
I presume a faulty CIA perhaps? At least that's what controls the keyboard on a 64 I think.
update: I reseated the PIA (6520) closes to the CPU no change, other than the fact that the keys that used to work still "work" but they show different characters now. I thought that was an indication that my 6520 is flaky so I swapped the two of them and there is no change. I also reseated the 6522 but nothing. Any pointers would be great. I still think that the PIAs are suspect, but swapping them around should have resulted in something. I have some 6581's (Motorola equivalent on order). Perhaps one of the "glue logic" chips in between?

The attachment in rbm's post works fine (thanks for the D81 version).

link no werko for me
Interesting, thanks to Robert B's recent post of Bill Herd's video links I now know that the LED is for using the built-in diag on my PET's ROMs. Now if I could only get a schematic of the required dongle (and magic decoder ring for the blinks) I'd be all set.
If I could only convince my wife to let me disappear for four days to make the 2100 mile round trip.... I could possibly work something out with a local (to you) courier/shipping service to pick it up and ship to FL if interested. I'd hate to see this stuff end up in a landfill.
Will do Robert, that's the exact one I bought. I also ordered a PetVet. If the monitor isn't the culprit at least the PetVet will make it easy to rule out the ROMs or RAM. BTW anyone know what the red LED on the board is for?
