I was trying to be politically correct, since a lot of people might now take offense at "master/slave" connotations. (Probably makes it worse.) But yes, they do have "Master/Slave" jumper setting markings on them.
Anyways, the point is that any CF card on the slave plug does not get detected by...
It's 40 pin.
Also, what I meant by dual-plug, is that there are 3 plugs. (One from the motherboard, two for primary-secondary/master-slave configuration.)
All right. I have had success in using XT-IDE on the Compaq Portable III, thanks to a patched BIOS ROM from VOGONS: https://www.vogons.org/viewtopic.php?f=46&t=62482
The problem I am having now is that I have a dual-plug cable, but it only reads and accepts one CF card. The other one is read as...
Oops. I was tired and forgot to add something to the first tip:
"ONLY keep the iron on for the amount of time it takes to melt the solder, and no more, as much as you can. If you do, you may damage the copper pad by burning away the epoxy that holds the copper tube (that the wire leg of the...
A few things to consider when soldering:
Don't keep your soldering iron on the parts and board too long. ONLY keep the iron on for the amount of time it takes to You may damage the pad by burning away the epoxy that holds the copper tube (that the wire leg of the board part goes through)...
OH BABY!!!!
IT WORKS!
I just ordered the cables and IDE adapters today (these of which I will attach to a 3D-printed frame later), but on a whim, I decided to try getting XT-IDE onto 27C64 EPROMS. Turns out they read just fine!
I'll update this with a newer version later, but MAN... this...
Since I have my Compaq Portable III in easy working order again, I want to try using XT-IDE as a pair of option EPROMS (note the missing "E") in the extra chip sockets provided on its motherboard. (That is, if it has the capability to do so.)
The only problem is, I can't configure anything for...
One year later, and it seems, with cautious optimism, I have figured out the battery problem in my Compaq, thanks to @modem7.
It was the chip type and the support circuitry around it. I got rid of it and the Motorola CMOS chip that I used, and swapped over to the Necroware DS12887 replacement...
Also, all you need to worry about is matching pin 1 on both of the plastic crimp housings (an arrow) with wire 1 on the ribbon cable (red wire). That's easy.
If you do that correctly, all you need to do is have the housing arrows on the same side as pin 1 on the converter board, and on the...
