II plus upgrade questions (Ultrawarp, RomX)

Submitted by skate323k137 on July 9, 2022 - 10:21pm

I just got my first II plus and so far things are going pretty well.

 

I've upgraded the PSU, and I put in a ROMX. The old ROM under the keyboard was a dianetics lowercase ROM, but I pulled that to install the ROMX completely. Presumably due to changing that ROM, I found intermittent boot behaviour with the mystery card in slot 3 which appears to be a generic 80 column card w/no cables. I pulled the (presumed) 80 column card, and things are pretty good.

Making 5.25 Disks--Follow Up

Submitted by nd2003grad on July 7, 2022 - 7:06pm

Hi All!

 

I posted a while ago about making Apple IIGS disks in general and have basically solved that problem with what I have.  I have an unusual setup in that I don't have a Floppy Emu, I have a prototype smartport device that is capable of 4X32mb HD images and that's about it.  So, to make 3.5 disks I merely converted the images to .po and then copied in GS/OS.  Worked like a charm especially for games that need to run from startup or don't work from HD image/aren't present on HD images for some reason.  So, great--that worked.

DOS 3.2 issue solved (Now on 16 sector disks)

Submitted by mochatea396 on July 7, 2022 - 2:03pm

I decided to post a new thread on this subject rather than going to the bottom of my old post and adding to it.  I have attached 2 files that I made which are DOS 3.1 and DOS 3.2 system masters on 16 SECTOR DISKS. These images can be written with ADTPRO like you would write any other 5.25 disk. Both have been tested in my integer basic Rev0. Since they are integer basic disks they will NOT boot in a iie.

Random question about Super Serial Cards

Submitted by profdc9 on July 7, 2022 - 11:19am

I have a question about Super Serial Card support on software such as ProTERM, Ascii Express, Agate, ADTPro, etc.

Does the software use the ROM on the card, or even check for the ROM on the card, when using the Super Serial Card?  Most of the logic on the SSC is to handle the paging of the ROM banks, and if the ROM is not needed for most software, a vastly simplified card with just a 65SC51 and line drivers could be used.  It seems to me for software that has its own drivers the 65SC51 registers would be accessed directly and the ROM would not be necessary.

Super Serial Card Layout

Submitted by profdc9 on July 7, 2022 - 12:38am

For those that are interested, I revised Joshua Thompson's Super Serial Card build.  I revised it to be 2 layer rather than 4 layer, and to use a 1.8432 MHz crystal and Pierce oscillator rather than a self-contained oscillator.

The project is a fork of the original project at:

and the original is at

How to Record Sound while playing games

Submitted by Floppy Deep Dive on July 6, 2022 - 8:46pm

I'm new to the Apple IIe World so I'm hoping there is an easy answer.

 

I'm recording my gameplay and I have no problem recording video but how do I record the sound?

 

Thanks,

Apple RGB color Monitor for Apple IIgs modded from 110 to 220V

Submitted by XLV2K on July 6, 2022 - 3:31pm

Greetings. I want to get an Apple RGB color monitor for my IIgs. They are very hard to find in the EU area, with EU 220-240V specs. So I was wondering, is it possible to get one meant for USA market, 110-120V spec, and mod it to 220-240V? What would that entail? I know I can use a step-down transformet but I would like to do a permanent internal mod. Is it possible? Are there any guides etc around? Thanks for your answers.

Making your Apple II useful as a *nix terminal

Submitted by bus_error on July 4, 2022 - 2:26pm

Hi all,

 

In my spare time, I've been messing around with getting my II+ talking with a Raspberry Pi running Raspbian (a Debian Linux distrib) as a terminal. To my surprise, I have actually carved out some success in doing so, despite the II+ being more or less barely able to do so.

Apple IIgs modem cable

Submitted by Hightray on July 3, 2022 - 11:58pm

I have what I believe is a null modem cable for my iigs. (It works with ADTPro) I got a modem that is 9pin. I can get this to work on my PC with a usb to 9 pin adapter. So I know the modem works.

As it is with the cable I have that is 8pin to db9 I cannot get the modem to work.

I want to build a cable that will connect to the null modem cable on the db9 side and re-wire it so it will work with the modem which is a db9 connector on it. It is a serial to wifi modem board.
