The Frob - Reproducing it.

Submitted by Thomas Cherryhomes on March 28, 2025 - 11:47am

I know some of you are interested in making clones of The Frob (2600 gamedev system for Apple ][) based on the findings I'm getting from my research work.

I will go ahead and say that it may just be better to make a modern equivalent based on the functional description of the hardware in Chapter 2 of the Frob manual: https://archive.org/details/the-frob-a-connoisseurs-guide/page/n15/mode/2up

IIc Text Characters All Garbage - HELP

Submitted by Wavedude101 on March 27, 2025 - 8:46pm

I was trying to test a small LCD screen I wanted to make into a monitor that plugs into the monitor port of the IIc.

C65ProDOS: Docs?

Submitted by Harry Potter on March 26, 2025 - 7:33pm

Hi!  I have a version of C65ProDOS I downloaded from I believe a mirror of asimov but not its docs.  I admit that I wouldn't really use it for [b]my[/b] coding--I prefer cc65--but want to support it for others, and I'm working on a special project that can target it.  Where can I find the docs?

Submitted by Jiroplas on March 23, 2025 - 1:59pm

I have a code that I will attach to this post. This file needs to be disassembled through some kind of disassembler so that it looks like Merlin assembler code. Or at least become readable! Help please.

IIC Rom 4X booting on external drive

Submitted by VIBR on March 22, 2025 - 6:16pm

Hello, 

I try to boot my emulator on a IIc using the external DB19 port. 

It says, no bootable device. 

Do I need to manage some line signals a different way (WR_PROTECT, SELECT ,..) a different way compared to IIGS to have it working ? 

Thanks 

Vincent
