EDM ROM for IIe

Submitted by Mrarkus on August 24, 2018 - 6:42pm

Apologies if this information is easily accessible, but I could not find it.

Does anyone produce the EDM (Extended Debugging Monitor) ROM or EPROM that I could use in Platinum IIe?

Apple Keyboard cutout

Submitted by dfnr2 on August 24, 2018 - 9:03am

I'm working on a case design and a keyboard design, and am wondering if anyone has a tested, known good pattern for the apple II/II+ keyboard cutout. A standard format like DXF would be great.

Enhancement Kit Issues

Submitted by slim_jimmy7 on August 20, 2018 - 6:55pm

Purchased an enhancement kit from ReactiveMicro. It is the US kit.

I also have the 80 col/64k card. On boot, the correct Apple \\e shows up. When I hit closed Command/Closed Apple/Reset I get multicolored squares instead of lines. I can also put in the PR#3 command and get 80 column text. When I boot into Proterm, ProDos, Agate, or Appleworks 3.0 I get the message: This program needs a 65c02 processor to run.

Looking for the name of the power connector

Submitted by RalfK on August 20, 2018 - 1:58pm

Hi!

Does anyone know the name of the power connector of an Apple II or Apple IIe? I want to give some of my IIe a new power supply but I don't want to cut the connectors from the Astec power supplies because I want to repair or service some of them later.

BTW I decided to buy the Meanwell RQ-65B and RQ-85B (26Euros/35Euros in West-Germany).

Regards
Ralf

Hi,
Is there a diagnostic test for the Apple IIe 80 Column / 64K Adapter that will identify the exact RAM chip that fails the memory test?
Thanks...

Clone ROM cards

Submitted by David_M on August 11, 2018 - 8:37pm

I had a few clone motherboards that were missing their ROM cards so I had some made.

The cards are for the type of common clone that has 64K and a z80 on the mainboard. The minimum order to get boards made was 10 so I have a few more than I needed.

Bare boards US$4 plus $3.50 postage, if anyone needs one, PM me.for my Paypal details.

Trying to compile a ProDOS program with cc65

Submitted by halkun on August 9, 2018 - 8:00am

I'm so close, but something is amiss when I'm trying to create a "Hello World" program for Prodos, that tuns

I'm using Applewin as an emulator and the latest Windows snapshot of cc65.

My simple hello world program is as follows:
---------------------
#include
void main()
{
printf("Hello World!\n");
}
-----------------------

Looking for advice on a hanging IIGS

Submitted by nlflint on August 8, 2018 - 12:52pm

Hello,
I’ve been trying to diagnose a hanging IIGS.

Symptoms:
After 30mins of play, my IIGS hangs. The screen freezes and a ctrl-Apple-reset goes to a black screen, no boot sound. It never drops to monitor like I think a random crash should do. When I power off and on, the screen shows colored checker board. After sitting off for 10-15 minutes it works again. This is with the chassis closed, and display on top, e.g. hottest config.

With monitor on the side, and chassis open, it never hangs, it has to be an overheating problem. My first thought is PSU.
