    Commodore PET Universal 8032086 measurements

    hahaha. Long blind already. Just about done with this now. Will get a PCB made up and assemble. Once confirmed all working (hopefully) I'll publish the schematic/gerbers etc.

    Commodore PET Universal 8032086 measurements

    Ah yes. Spot on. Thanks for spotting that. Been looking at traces for too long. :)

    Commodore PET Universal 8032086 measurements

    For C37, the trace shows a short on the bottom later (Image is mirror so it matched the top layer) On UB17. I forgot to add, it's only pin 12 that I can't see a connection for. I can't see under the chip, but from the reverse engineering I've done I can't see a way that the trace is routed...

    Commodore PET Universal 8032086 measurements

    I'm busy with a project to, as close as possible, recreate the PCB layout from scratch for the Commodore PET Universal 8032086. About 95% completed and have been using the schematic diagrams and hi-res pics of the motherboards to re-create the PCB layout. During the reverse engineer I've...

    PET 8032-32B How many chips should be missing on the m/b?

    Thanks, that's a big help. I also found a few modern clones based on the 2001 but as you said nothing for the 80 column board. Shouldn't be too difficult with the pics and circuit diagram to come up with something. Opened up the CRT and it looks like the pics you posted. So at least someone...

    PET 8032-32B How many chips should be missing on the m/b?

    Interesting project. Crazy prices though. Will keep watching on eBay to see if any other boards come up but as with all the retro stuff the price just goes one way. I've managed to find all the schematics/layout and a few hi res pics of motherboards. In the meantime I'll start adding all the...

    North West - about 20 mins North of Manchester.

    PET 8032-32B How many chips should be missing on the m/b?

    I don't suppose anyone knows if there is a 8032 clone PCB available. I can find a clone PCB for the 2001 but nothing for the 8032. For the price that these motherboards are going on eBay it might be cheaper (and lots more fun) to build one from scratch. Are there any high res pics of a...

    PET 8032-32B How many chips should be missing on the m/b?

    Always knew it was going to be a long term project. I'll keep on the lookout for a PCB and also a CRT - maybe the PET Gods will help and I"ll get both and can get 2 PET"s working :)

    PET 8032-32B How many chips should be missing on the m/b?

    Thanks for the detailed explanation. Getting the PCB to a working state doesn't sound like too much of a problem. The big problem I have is the mismatched CRT so will have to go hunting.

    PET 8032-32B How many chips should be missing on the m/b?

    Over $200 for the motherboard. Ouch.

    PET 8032-32B How many chips should be missing on the m/b?

    Thanks, was afraid of that. :cry: Will hunt around for a 8032 board, or a CRT for the 2001-N PCB

    PET 8032-32B How many chips should be missing on the m/b?

    Noooo. A real frakenstein PET. :( Is this doomed to failure now. I need a matching PCB for the 8032?

    PET 8032-32B How many chips should be missing on the m/b?

    That's not good. Is that not going to work with the 8032 or can you mix and match?

    PET 8032-32B How many chips should be missing on the m/b?

    I'm also wondering if the main board has been swapped from another machine? Can anyone identify is this is all original parts? PET 8032 Motherboard Assy 320351 E (PCB part no. is 320350 Rev B) Also confusing is one of the ROM chips is a 901447-29 which according to the list is a editor ROM is...

    PET 8032-32B How many chips should be missing on the m/b?

    Just after posting I think I found the layout: http://www.zimmers.net/anonftp/pub/cbm/schematics/computers/pet/2001N/320351-6.gif Missing some important chips and even worse some idiot put the chips in the wrong location and backwards!! Agghh!!! Looks like I'm in for the long haul fixing...

    PET 8032-32B How many chips should be missing on the m/b?

    Finally got my hands on a PET 8032-32B from a friend. He got it from someone else many years ago and from what I've been told it was last working but alas it's dead as a doornail now so am trying to revive it. Before I go down the rabbit hole of troubleshooting, I'm new to the PET world (But...

    XTIDE tech support thread

    Thanks for the tips. Quite a eventful last few hours I tried RAYXTIDE and it's not detecting the card. I then tried the card on my IBM 5160 and it decided to let the magic smoke out. A shorted tant cap. :mad:I've replaced a few but must have missed one (C58 which looking at your docs is very...

    I've spent a few hours on this and think I have all the settings right but still cannot get the bios to load IBM Model 30 286 All cards removed except for XT-IDE Rev 4 Onboard HDD and FDD Removed. On the XT-IDE Card I've got the address jumper set to 300h J1 & J2 set to hi speed (Also tried...

    I've been at this too long and not ever reading properly :oops: XTIDECFG.COM also allows saving changes to XTIDE Universal BIOS images for later programming with other devices or programming software
