I was thinking that too, but it seems like it would be insane to try to power an MFM bubble off the appleII bus power.

They both came from the same university auction in the early 2000s, and appeared pretty heavily used even then. Both blue-logo Lexmark models with the attached cable, for whatever that's worth. I...
Well shoot.
Do you think you could drill the heads off the plastic rivets, then carefully drill pilot holes in the stubs and reassemble with screws?
IIRC the buckling spring model Ms have a rubber membrane too, but it's not quite the same as the rubber dome keyboards. There's a pivot plate that snaps down on the membrane when the spring buckles,...
Here's the one I was thinking of. He has someone testing it in a Model 3 right now, but it isn't quite ready yet. https://github.com/calphool/M4ToVGA
I don't think the frequencies are compatible with NTSC.
There's a guy on one of the TRS-80 discords who made a contraption that replaces the CRT analog board and outputs VGA. It sounds to me like...
Tektronix 11401 mainframe DSO scope. A beautiful ol' 70lb 4U rackmount boat anchor, mid '80s vintage. Has a '286+'287 inside, I think. The vertical amp modules that came with it provide 8x 300MHz...
Sorry, heh. It's been many years since I dealt with 10base-2. ;P
The most important question though is..........
Will it run Dwarf Fortress? :3
I've done that on some smooth plastic parts, but those EX/HX'en have a textured finish that doesn't take kindly to sanding. :(
A machine that late should have 16 bit ISA slots, which makes things a lot easier. Most any cheap/ubiquitous 3c509 or NE2000 card ought to have a 10base-T port on it.
If you do insist on using...
Nice.
But I do have an extra lower sheet metal doohickey that you can have if you want it (although it is missing the ratcheting foot and part of it is slightly bent). You may have to improvise...
I like Slackware on old boxen, but whether or not the most recent releases will run on a 686 machine entirely depends on how much RAM you can stuff into the thing. I run older Slackwares on 486...
Just wanted to update anyone who is interested.
I guess the proto-prototypes are on the Slow Boat and might get here Someday(tm). It seems to be in tracking limbo for the last little while.
Yeah, I've done SSL on a 25MHz 030 and hoooooooooo boy it is slow.
I am totally with you, man. My thought is that the offload network interface should handle the "hard" stuff, like the actual protocol stack, the crypto (because like as not if we want to play on the...
I think the problem (if we can call it a problem) of using uCs that are several orders of magnitude more powerful than the actual host system to interface with more modern hardware is something that...
There's one of those on ebay right now, but no keyboard. :(
What I want most to add to my collection at the moment are an HP2640 and a Tektronix 4014 or similar. And some variety of Data...
Boy they sure are pretty machines though, even if the keyboard is meh.
Some kind of wifi modem is great with them. Saves fooling around plugging/unplugging cables to switch them between host...
Yeah. Oldskool 10mbit AUI+BNC though, not one of the newer 100mbit twisted pair cards. It was a neat machine, other than being kinda ratty. I'd have put $300 on it, but it just wasn't worth much...
*coughs softly*
The nicad bomb looked like it leaked a bit in the pictures, but hopefully I can fix it. Paid too much, but I have been looking for a Genesis\PC Model 25 board for like 10 years or...
Yeahhhh, I was looking at the eZ80 too, but it just doesn't look like it's compatible enough to be a drop-in super-replacement in these old boxen. All those built-in peripherals get in the way.
...
Alright, so. There has been a good bit more interest in people getting these.
But, given that USPS is all screwed up right now, apparently with 4-5 week delays...
And given that, while I am...
I was thinking about that to begin with, but when I started laying it out I got to feeling like it was taking up too much of the prototyping space. My plan was to use a 688 and some jumpers to...
That sounds like what I was thinking of. IIRC in my case it was something further into the video generation circuit, but whatever it was was pretty much directly tied to the line driven by that soft...
