I'll post photos soon once I get everything fixed up and planning on sprucing up the system with cleaning and retr0briting of the keys (gotta get...

Nice save, but make sure to inspect the P/S thoroughly. Early Compaq portables have a tendency to have a quick and often fatal death at that point....

Try searching for Tandy 2000 Service Manual Phil. It contains M4853 schematics.

a 5364 is a different animal than a 5161 or 5160. If google is leading me in to correct direction, it looks like you would connect a 5160 to a 5364...

Congrats on the Portable! They are great systems. Sounds like yours is coming along nicely. Got any pics! I think the replacement foam pads will...

Sure! I didn't realize I hadn't added any pictures yet! Gimme a couple of days and I'll try to set everything up! Here are some pictures from a while...

I just saw this 1 minute ago, and it was sold..

Didn't last long. Someone here get it? Mike

I have done this on an ATmega8515 myself, using an external 32 KB SRAM. It is possible to have the CPU core live exclusively within the CPU...

All UNIX systems are generally capable until the year 2038 (because of the 32-bit time_t since the Unix Epoch). However, not all tools can deal...

You'll need to get an adaptor to make the Gotek connect to the floppy controller in the 1100FD. They sell them on eBay.

In my current socket 7 system I'm using a 40gig 2.5" sata with a sata<->3.5" ide adapter, ignoring all but the first 8gig. Still new enough that I've...

There is also this, also with a MFM style header and molex plug:...

You could try Snooper, it can detect various hardware problems. https://macintoshgarden.org/apps/snooper-20

There is a ton of inventory available for cheap if you spend time trawling and using many different key words in your search. Plus doing this daily...

I like to use DOMs They are just P&P replacements for IDE disks.

Photos of the extender and receiver cards used with the IBM 5161 are at here].

Could that be an MFM hard drive card? Sure looks like it with the 34 pin and dual 20 pin connectors. The four pin connector is for power.

I dont care how good you are and how well stocked your electronics bench is. I really think its unlikely hobbyists will be repairing VLSI IC's on...

You said that will wait forever for this model. I don't know, due to short history on ebay. I bought newer versions from 91' which is a bit shorter,...
