Hack/test Apple //e upgrade?

Apple //e non enhanced 6502 PAL

I have one Apple //e that i use for testing cards and generally playing & hacking around, as my main rig is Platinum //e that have the parts installed permanetely. This system is PAL, non enhanced 6502, Apple //e with UK-keyboard but i wanted to upgrade it to NTSC. As the position of AUX connector on PAL //e aligns up with Slot 3 and that wont allow installing long cards to Slot 3. I find that bit annoying. And i had one NTSC board available so i thought to just swap it around and as well, install better, in this case, Applied Engineering heavy-duty power supply to it.

Original cards setup:
#1 FastChip //e (a2heaven)
#2 quikLoader (D.Mutimer)
#3 -empty-
#4 TimeMaster II H.Q. (a2heaven)
#5 -empty- 
#6 Disk II (apple)
#7 VGA-scaler (a2heaven)
AUX RAMWorks 8M (a2heaven)
+MultiFont custom ROM (a2heaven)
+Regular original Apple gold long model power supply

Putting in parts and suprises!

NTSC vs PAL board differences

So i removed all the cards and put the case in parts. Then, it’s easy to just put it back together with new PSU and board… but, NO. I had totally forgotten that the design of the NTSC board is pretty much different to PAL one. So.. the keyboard connector and speaker connectors are in different locations wich means.. they have longer cables. Oh no!

OK, not biggie. Making longer (abx. 32cm) keyboard cable isn’t really that difficult, so i got 1 meter of 26pin flat cable and some IDC26P female connectors. It took few minutes to get one done with correct tool i luckily had bought few years ago when i made new Disk II drive cables for myself.

I however did not get longer cable for the speaker (i tend to keep it unplugged anyway) but that’s something maybe needs to be done later.

 

AE heavy-duty power supply:

It really looks good doesn’t it? Applied Engineering is one of my favorite companies that made products for Apple II-line.

And it’s beefier than the regular, stock power supply that Apple used.

VGA-scaler installation:

As i used the VGA-Scaler (from a2heaven.com) i installed that too. It’s installed the same way as in PAL board, but just the chips are in different location. I had to use longer cable to reach the chip in location F5 that i was using with the PAL board.

Installed in : SLOT 7
Board type: Apple IIe NTSC 1982, 620-0064-B/607-0164

Installation:
– SEROUT > C5 74LS10 PIN 3  
– GR > D5 344-0022 PIN 2 
– 14M > F5 74LS166 PIN 7

New cards setup:

AUX RAMWorks 8M (a2heaven)
#1 -empty-
#2 -empty-
#3 Transwarp (AE original)
#4 TimeMaster II H.O. (a2heaven)
#5 MicroDrive/Turbo CF-HDD (reactivemicro)
#6 Disk II interface (apple original)
#7 VGA-Scaler (a2heaven)

I might change the keyboard too, i feel one of the other //e’s i have does have better response keyboard… different switches?
