Tried hooking up the HxC to a Tandy 1000TX with it hooked up the drive status light stays lit (like it's hooked up backwards). So I tried flipping the ribbon around and the computer won't turn on. Have the jumper set to standard PC A:\ setting... Comfirmed it works on a 486 computer, amiga 500 and TRS-80.
Is it just incompatible or any idea's??.. I have a older Tandy SX I might try later and also have a PC jr I haven't tested yet.
Do you have the floppy pinout of this computer ?
Found it. It seems that tandy have put +12V & +5V power supply lines on the floppy cable.http://vintage-blog.peacon.co.uk/downlo ... -vol-1.pdf
You need to cut wires 3,5,7,9,11,29,31 and 33 on the floppy cable before pluging the HxC (or any standard floppy disk drive).
The "computer don't start" is probably the right cable way, but you need to cut these lines to avoid shortcut...
Please note that you have probably damaged some lines of the HxC with the +12V voltage...
Hopefully you have just to change the 74LS38 chip...
So be careful with this computer ! It is dangerous
