Apple //c donation!

apple_iic_setup_s
I got this nice set of Apple //c goodies from ex. Apple II user, let’s call him here “Rancher Paul”. He used to be very active user and had Apple //c with 8Mhz Zipchip and even Apple IIGS (one of those few that got importedhere) but those are long gone now.

There were also bunch of floppies, but mostly private Appleworks-data disks so i imaged those first and delivered them to Paul.

taking_apart_s
So this nice Apple //c then, i did what i usually do, i took it in parts, checked all details and parts and did basic cleaning and tested to be sure if it works or if there would be some repairing to do. 

apple_iic_in_sauna
For the case and the keycaps, i disassembled the whole unit and washed the whole case from all dirt it might have collected over the years. I don’t do retr0bright.. should try it some sunny summer? The sauna is good place to dry things up..

keyboad_s
I removed the caps and washed them well. I don’t use (should i?) the keycap puller tool, just regular screwdriver will do.

keyboard_open_s
..they do collect all kind of dirt on them over the years, or decades.
 

keyboad_rubber_s
One thing i hate with the //c is that darn spillover rubber protection mat.. 

disk_ii_in_parts
External drive,

Took the exeternal drive to parts and cleaned the case and the inner parts, the head and adjusted the speed.

connector_adapter_s
The external drive, Disk II, had quite clever adapter to DB19.

apple_iic_board_s
The motherboard,

The board was quite clean but did some cleaning but not with isoprophyl alcohol in this case. It looked fine. It had the original ROM255.

apple_iic_working_s
Things back together and testing (with my own laptop-powersupply to be sure) and it worked fine. I did not attach VGA or composite color adapter so there’s no colors on screen.

apple_iic_ready_s
Nice Apple //c with original ROM255 (The Apple ][+ logo there just for the fun of it..)

 

Thank you Paul!

Apple //c – Color video Modulator/Adapters:

There were several diffrent color adapters for Apple //c produced by Apple:

euro_2_s

PAL Modulator/Adapter
Model A2M4023 

The adapter is for PAL models for color video output and has composite out as well as RF-out. 

 

a2m4020_s

PAL Modulator/Adapter
Model A2M4020
P/N 825-0830-A

This will generate PAL colour (RF) output from NTSC //c.  With PAL //c with this adapter will only produce a monochrome picture. 

Modulator/Adapter
Model A2M4020
P/N 825-0817-A / 825-0816-A 

This is for NTSC model to generate color RF-output.

lecatmauve_s

Le Chat Mauve : //c RVB Peritel 
Model AM2M4020F
Made in France

 This is for PAL models and it have RGB, SCART-connector.

Custom ROM for the Apple //c and //c+

Now, what about the custom ROM then?

ROM 4X and 5X are enhancements to the Apple //c (4x) and Apple IIc+ (5x) firmware ROMs.

Basicly:
It adds the following features to the Apple //c and IIc+ firmware:

Identifies and reinstates a bootable (it must have something that looks like a boot block!) RAM disk from battery-backed expansion memory (see below), such as the RAM Express II+ from A2Heaven.

Provides a menu of various tools upon pressing CTRL+CLOSED-APPLE+RESET (or holding CLOSED-APPLE when powering up), that let you:

*Enter the monitor unconditionally.
*Reboot the machine (enter standard boot sequence).
*Zero the RAM card, in case it is corrupted.
*Execute the machine and RAM card diagnostics.
*Tell the machine to boot the SmartPort, the internal floppy drive, or an external floppy drive.

IIc only:
*The system drops to BASIC if no bootable device is found (this is the default behavior in the IIc Plus).
*Configure default boot device by saving a file on the RAM Disk.

IIc+ only:
*Menu control the built-in accelerator.
*Accelerator settings persist across resets.
*Build option to default the system to 1 MHz.

This firmware enhancement identifies a ProDOS boot block on the RAM disk and, if found, restores the appropriate screen holes to make the RAM disk bootable and prevent firmware or ProDOS from re-initializing it.


INSTALLING TO APPLE //C+

eprom_installed_s
ROM-installed:

It is easy to install. Just open the case and lift the original firmware ROM-chip from it’s socket, with tool of your choosing and insert the newly made ROM (EPROM) in same socket.

ae_card_to_be_installed_s

I also installed an never used, Applied Engineering RamExpress to my Apple //c+ as the unit was opened. The card originally had 256k RAM (soldered) so i added some more. I was able to find from my stash just two (original) sets of (8 chips per set, 256k) “Apple II 256k Memory Expansion” boxes. Those were sealed but really they are ment for using so i had no ethical issues opening them. I could possibly lift some RAM from i.e. slinky //e RAM-card but that could be done later. Or most likely, i’ll replace this card with modern version, like A2heaven’s “Apple IIc RamExpress II+” that is the good option for the //c and //c+ users right now.

ae_ramexpress_installed_s
RamExpress installed:

My Apple //c+ now holds some modern upgrades:

-Universal Powersupply (from Mark Wise)
-VGA-adapter (a2heaven.com)
-Applied Engineering RamExpress (768k RAM) 
-FloppyEmu w/adapter (first rev.)

USAGE?

menu_accel_s

All these features are very welcomed to //c and //c+ users. For //c+ users, setting the CPU to 1 MHz even after reset is very handy when you want to keep the speed at 1 MHz. This is BIG plus feature. The annoyance of choosing the speed after every reset is infernal when you need to remember to do that!

Boot-control is really nice, there’s different needs for different media and options so choosing it from menu is so much more convinient. Loving this bigtime!

The RAM-card options are handy if you’re using one. 

This is everything in one place upgrade and absolutely MUST for //c+ users. Wonder what else there might be what could be accessed and configured?

Konttorikone-messut 1986

Konttorikone-messut (1986) was big retail show in downtown Helsinki, held in Messukuskus, Pasila.

These pictures are taken by unknown person and donated to me by Markku Jussila.

km1986
The stand of Mustapörssi have also an sign “Apple II Forever” and clearly an Apple //c there for display. But in 1986, as the Macintosh had arrived (and possibly here, Macintosh Plus) the Desktop publishing was the new big thing and Apple ][‘s started to fade away from mainstream.

km1986_5
Apple Computer stand and Mercantile Data Oy. What an nice big display there!

km1986_3
Introducing the Macintosh Plus i assume?

km1986_4No Apple ][‘s to be seen anymore…

Donation of Macintosh Plus?

macintosh
This picture is actually not releated to the topic itself, as this must be the first Macintosh 128k been given to the first owner (or intruction time) – but as this blog is not about Macintosh, i’ll just leave it here.. Historical importance is however valid.

Laser Shop!

Laser Shop sold Apple ][‘s as well, in this case, the Apple //c which got LOTS of ad’s in Microcomputer magazines trying getting back to the market. But.. Apple //c was quite expensive if you compare to the other 8-bits, like Commodore 64 or Spectrum whose ruled over the market before Amiga and then later Windows units.

Z-RAM II for Apple IIc (Applied Engineering)

Nice ad for Applied Engineering “Z-RAM II” for Apple //c from Finnish microcomputer magazine “PRINTTI” which were just finally, scanned to PDF and can be found online.

Wonder how many of these actually were bought? I’ve never seen any so far.

Update!
I managed recently found an Z-RAM II board! It was installed in German Apple //c (yet to be received).
