Photos of my Apple bits and pieces

Postby RonTurner on Mon Jun 23, 2014 11:43 am

This thread is where I intend on putting up photo's of my Apple items as I go through them gradually
some may be interesting, some maybe just normal Apple items :wink:

Sundox Duel CPU 6502 + Z80, this is the spare motherboard for my working Duel CPU Sundox.

Note: for some reason a person (unknown) has tried to scratch the "Z80A CPU" writing off and
put a "made in Taiwan sticker over it" but you can still just make out Z80A ?

This is usually done to prevent to design from being copied.

Interesting.

One thing I'm curious about. Is there some kind of "switch" or key-combination which allowed users to somehow toggle between an Apple DOS (using the 6502) and CP/M using the (Z80)? Or will such machines simply recognise the kind of disk being inserted and use the appropriate processor?

It'll function as an apple II with a softcard. i.e. it's kind of CPM.

It has a CPM software interface and runs on the Z80, but it boots with the 6502, and all low level services run on the 6502. :D
"dsakey" on trademe. Apple II's are my thing.

Continuing with the Duel CPU theme... Z80B / 65C816 :mrgreen:

Z-RAM Ultra 3 for the Apple IIc by Applied Engineering, 1Meg RAM, Z80 CPU, Clock (I have removed the battery).
Its a bit of a bonus when you get three functions on one card to fit inside the very compact design of the IIc 8)
Image

Image
Optional 65C816 16-Bit CPU plugs right into this card without any changes, giving you a 16 bit processor.

This is one of the Z-RAM Series of three cards, Ultra-1, Ultra-2, Ultra-3, the later having all three features,
an Ultra-1 was a RAM upgrade only. Ultra-3 has a High speed Z80b for CP/M

(from an old brochure)
Z-RAM Ultra-3 with 512K RAM $549
Z-RAM Ultra-3 with 1 Meg RAM $849
Optional 65C816 CPU $79
"Make Apple Works run 20-30 times faster"
Five year warranty !

i'm going to assume this card has 512K ? RAM populated, and if all the empty sockets where populated it will have 1 Meg of RAM.

The plan here is to roll without the battery, top up the RAM and install a 65C816 16bit CPU and fit it to
one of my Apple IIc's, that will be one grunty little Apple II that has a carry handle
and is as small as some laptops and not to heavy :D It wont keep the real time but I don't
want to open it one day and find acid damage, I don't run batteries in my Apple GS's either,
there just is no real need :wink:

Still Duel theme, Duel NTSC + PAL Apple IIe

This is an NTSC video and RAM card installed in a PAL computer.
Image

Here it is running, The TV set is running off the PAL video out, the Apple IIe monitor is daisy chained off the PAL TV set, the Colour Composite monitor is running off the Card.
Image

NTSC vs PAL: I switched the cables, now NTSC feeds into PAL CRT's and PAL feeds into NTSC,
SO MANY PEOPLE BELIEVE YOU WONT GET A PICTURE ! WRONG, YOU JUST DONT GET COLOUR,
MYTH BUSTED :wink:

Speaking of your collection... it's looking like you're beginning to sell quite a lot of it?

Not at all... even when I did sell a couple of Apples recently, I was still purchasing other 8-bit computers,
so the total amount of hardware I owned actually increased other this time period :D

Here is a quick list (I may have forgotten to list one or two) :D

Symbiotic Fast Noxy Card
Image
I have plugged it in, and LED's light up, computer doesn't do the normal Apple//e boot with this
card installed, it goes straight to an 80 column screen, saying "Symbiotic Industries" , "Loading Please wait"
but thats as far as it gets without a hard disc plugged in.
:D
