Gibberish video upon bootup of an early series Apple ii

What could be wrong with my Apple ii? When I turn it on, I only see gibberish video output. No speaker beep sound.

Am not sure if 1) am not using the right display - just attached it to a video grabber USB dongle. 2) my keyboard is not working hence the reset signal is not being sent to the computer for it to boot properly. 3) something else is wrong.

I had already replaced the power supply with a new one from Reactive Micro.

EDM ROM for IIe

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

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

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

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

Clone ROM cards

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

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");
}
