IIGS Questions

Submitted by Gumdoc on September 22, 2021 - 5:14pm

Hi All,

Loving my //e but I'm thinking I want to add a IIGS to the mix. I want to try to figure out what will I need on top of my current setup to get it working, as most IIGS systems I have seen for sale are incomplete.

My //e has a color composite monitor, DuoDisk (with the 19-pin connector), two Disk ][ drives (with the 20-pin card), FloppyEmu, and a null modem connection from my Super Serial Card with the RetroFloppy cables to my PC for ADTPro.

I assume I need the following for the IIGS, what am I missing? :

 

1. RGB monitor with cable

IIgs Teach App doesn't restore proper video mode when quitting and returning to GSOS

Submitted by mkinn on September 19, 2021 - 8:16pm

After adding a LOT of init's, CDEV's. and Finder extras, I screwed up the teach application. I tried to re-install it, buit no dice, same problem.

Anybody seen this before, and is there a CDEV that I can use to restore the proper 640 desktop graphics mode without exiting to the monitor?

If not, how can I do that WITH the monitor? Very hard to find this info.

Did I get scammed?

Submitted by coolk on September 19, 2021 - 11:50am

I recently bought a working Apple IIgs and can't shake the feeling that I grossly overpaid.

Specs:

Woz edition cpu

monitor

3.5" disk drive

Keyboard & mouse

AE Transwarp Accelerator

4mb ram

focus drive

Joystick

 

I paid $1500 for this. Is it too much?

Boot Sequence

Submitted by Gumdoc on September 18, 2021 - 8:02pm

Hi All,

 

Was wondering about how the //e handles booting. I currently have two controller cards, a 19-pin that I use with either my DuoDisk or Floppy Emu, and I just picked up an older Disk ][ controller card, the one with the 20-pin connectors. If I keep the 19-pin controller in slot 6, and put the 20-pin on in slot 5, will the //e ever boot from the slot 5 disks if there's nothing in the slot 6 drives? I know I can probably do a PR#5 command to get it to boot from slot 5, but was curious if the system will look beyond whatever is in slot 6 if both drives are empty.

Apple II Bank Switching

Submitted by MicroCoreLabs on September 18, 2021 - 4:20pm

I am trying to implement bank switching in my drop-in 6502 emulator, the MCL65+, to allow both the RAM and ROM to be implemented in the microcontroller's emulated 6502's rather than use the memories on the Apple II+ motherboard... and I seem to be missing something... The MCL65+ is a C emulation of the 6502 running on a microcontroller on a board which can replace the physical 6502 on the motherboard.  I have implemented the three memory blocks: ROM, Bank1(12K), and Bank2(4K) and I snoop 6502 read accesses to the 0xC080-0xC08B addresses to switch between them.

keyboard data and strobe workings

Submitted by dfxgordon on September 17, 2021 - 7:12pm

I have a code that is supposed to work on a II plus or a IIe, and I want to use the soft switch at $C00E to make sure the alternate character set is off (required for flashing text).

It seems this should be OK, but then I noticed in the Apple IIe reference manual it says "in the original Apple II, memory locations from $C000 to $C01F were used only for the keyboard data and strobe functions."  This way this is phrased got me worried.

"Essential" documentation recommendations

Submitted by granitepenguin on September 17, 2021 - 1:19pm

What do you consider "essential" documentation to pick up?  I'm thinking stuff like User Guide for whatever system (IIe Platinum, in my case), but what other guides, books, etc are out there that you'd recommend for someone starting from zero?

 

Thanks

IIe Platinum video sync a little finicky

Submitted by granitepenguin on September 15, 2021 - 2:14pm

Hello, all. 

 

I'm new to the Apple II retro scene (had a II+ in the 80s).  I just got a IIe Platinum at VCF MW this weekend and have started the process of building up the system.  I'm currently using a little 12" LCD with composite for the monitor, but the video sync is not great.  I usually have to start the IIe, then turn the TV on and off a couple times to get it to "catch" the video and show up properly.  The system works fine otherwise; it's just a little inconvenient to fiddle with it on a reboot.
