It looks like I didn't document the base dimensions. Maybe if I put it on the spreadsheet (sheet1) then the base was big enough, but it's been more than a decade since I put this together, so who knows at this point. Grrr. Forum won't accept an .xls file, so I'll have to wait until I'm...

Thank you, @Bolle . I can't remember exactly where the chips are at the moment. I know they're somewhere really safe. And I think they're in an anti-static bag inside a manilla 4 X 6 (5 X 9?) mailer. Now where did I put that... I checked the most likely spots. I will contact you when...

Nothing to add. Just posting to admire your work. Excellent testing. Interesting results.

Yes, it was. I'm sorry for my poor memory. I figured that out after reading a bit more of the thread last night, but was in too much of a hurry to go back and edit. It's great you each have an example of one of hte host adapters. This is so cool. One Plus adapter. One SE adapter...

It sounds like you have options. Even if you don't have the installer on the Silicon drive, you should be able to make a LocalTalk connection to another Mac through the serial port and mount the installer disk from there. Although, file sharing didn't come along until Sys 7? So you need 7...

So do you think if I asked him to read out the programming on the two GALs he'd help? I know I just need to ask. I mainly haven't because I'm just not at a point to do anything with the info afterwards. I do have one GAL from each (floppy and SCSI adapter) that have been removed from their...

Nice. Thank you. My Outbound journey started back in the early/mid 90s when CompuAdd (computer mail order and store) was having what they called their "back dock sale". Clearing all the junk out of their warehouse. I found 7 Outbound Laptop 125s there. None of them had external...

There is one 20 pin PLCC GAL on the board. Everything else is "standard" parts. Some of them are difficult to find now days. Discovering the programming of that GAL would be the biggest challenge. Parts list: https://www.prismnet.com/~trag/Outbound/Adapter%20Parts%20Lists

Just to confirm I understand what you're saying. Then the X500/X600 aren't using the -5V for teh serial ports, because it's being generated elsewhere? My devil's advocate to that is that the serial ports on the X500/X600 are supported by the AMD79C950 which supposedly contains an 85C30 cell...

@techknight did a thread on a full rebuild of an IWII a while back. You might look that up and see if htere are any relevant portions.

Totally agree. The double power trip should really be limited to diagnosing whether you need a new battery. Also agree about the other forms of death. And will add heatsink grease turning into chalk. Often this won't completely kill it, it just won't run reliably for more than a few...

@cheesestraws @unity Catching up on you guys' progress got me wondering... So I am as sure as I can be without ordering part that I have the cable components identified correctly. Years ago I got some DX10-28 samples from the local Hirose representative: I just pulled an Outbound cable...

I posted this in another Outbound thread, but for @cheesestraws' benefit: Plug -- https://www.digikey.com/en/products/detail/hirose-electric-co-ltd/DX30A-28P-50/3977834 Housing for Plug -- https://www.digikey.com/en/products/detail/hirose-electric-co-ltd/DX-28-CV/3977844 For completeness...

Story of how you found it? I would like to enjoy the vicarious thrill of discovery. :-)

Outbound Laptop 125 Cable. Found all the parts, except the actual wire, but I didn't look for that. The good news is that the components are still available and in Active status. The bad news is that it's a $40+ cable. Two $10 components at each end. Plug --...

You're the fellow who picked up the partial docking board that was on Ebay a year or three ago, right? I haven't had time for the forums much this year. Kind of stealing this time. I have installed replacement hard drives many many years ago. So this memory could be flat out wrong.... The...

The 8600 board, non-Mach 5 CPUs, and the 8600 Enhanced (AKA Kansas), Mach 5 CPUs (and upgrades) only, can be distinguished in three ways. The Enhanced (Kansas) board should lack the Cache slot. It will have a position for the cache socket but it won't be installed. ROM chips are four 1.1" X...

The battery advice is good. The 6100 really doesn't like to start up without a good battery. The work around is the double-power switch trip.

Nice. Just for clarity, is that the Precision Color or the Precision Color Pro? Also, Futura SX or Futura II SX? Lowendmac is frustrating. Or my memory is bad. The Thunder GT was marketed by Radius as the "Thunder 24GT". IIRC. The "Precision Color" card in LEM's description is the...

I don't have a datasheet on the latter part, but a little more context might help folks make an educated guess...
