Engineering notebook for Apple IIGS

Submitted by Waterbug on October 10, 2018 - 4:48pm

I was tossing old stuff and came across my old engineering notebook from 5/89 to 3/90 when I quit Apple. So it's things I was working on after the IIGS shipped. Basically what an extension of Taskmaster would be, or bring the concept of Taskmaster to the Mac. There's some stuff from after being at Apple.

 

Before I toss it I wanted to know if anyone collected such stuff and wanted it.

Bigger monitor for IIgs

Submitted by retrobyte12 on October 9, 2018 - 9:02pm

I was wondering, what's the most popular option for a bigger RGB monitor for the IIgs? I have the original one, but it's just a tad too small... I'm thinking of using a Commodore 1084S, but I'm not sure if the picture quality compares...

Apple II Terminal Emulation on a Mac

Submitted by Byte Knight on October 9, 2018 - 5:12pm

I've got the ZOC Terminal program really dialed in for my MacBook so it feels like an Apple II.  It's a fun and easy way to get on the Apple II BBS's.

Quickloader Reboot

Submitted by David_M on October 8, 2018 - 3:11pm

Some of you will be aware I started work on designing a more compact verison of the original Quickloader card.Macnoyd did the hard work and created a schematic of the original card for me to work from.

With that schematic I put in a solid 3 hours work created a new smaller, low chip count design  and board layout.

Well tonight I kicked in another 5 hours and wrote the GAL rules that will pull it all together and make it work.

WTB KR9600-PRO

Submitted by TedThompson on October 5, 2018 - 4:01am

While I can't be 100% sure, it would seem having an AY-5-3600-PRO in a socket for a KR9600-PRO would not be a good idea. Never the less that's what I have and I'd like to put in the correct part before I continue troubleshooting this mobo.

 

Anybody got one?  Anybody know a reputible source (I've heard there are re-labled forgeries out there)

 

Oh and something that doesn't ship on the slow boat from China preferably... :)

Apple IIgs with bad onboard ram?

Submitted by thephred on October 5, 2018 - 1:43am

Hey guys! I have been getting more and more excited about Apple IIs for a bit and I finally broke down and bought a IIgs on Ebay. It arrived and I set it all up and played with it a bit today. Turns out it is a Rom 01 with a 1Meg memory expansion card. As I played with it I noticed two things:1) There is a line in the middle of this screen that shows up only when text or graphics other than the background color intersect it. It shows up on the RGB monitor as well as the composite port.

2) It crashes when loading some software.

Apple IIe (clone) problems

Submitted by migueletto on October 4, 2018 - 3:54pm

Hello there, this is my first post.

 

I have a Brazilian Apple IIe clone, named Tk-3000. It was produced in 1986 and worked fine for many years, up to a few years ago. The first problem was that the disk drives began to fail, but I could still boot to AppleSoft Basic (but that is not the topic for today). Then it started to show memory corruption and loss of video signal. I have been trying to troubleshoot it for a long time now, with no success, so I found this forum hoping someone could offer some advice.

Trackstar - Apple II clone on a PC ISA card - new website up

Submitted by DeathAdderSF on October 4, 2018 - 4:18am

Hey guys,

Just a heads-up to let you know my Trackstar website is up, covering the E, 128 and also Quadram's Quadlink <-- These are all "Apple II on a PC ISA card" Apple II clones. Really cool little devices!If you own these devices, esp. the Trackstar E or Plus, there's HUNDREDS of disk images in its TrackStore format that I've converted manually.So you can download and enjoy a HUGE amount of software without needing real Apple II disks.

2gs programming

Submitted by retrobyte12 on October 3, 2018 - 10:35am

I'm thinking about learning assembly language to program a game, and I want to use the Apple 2gs. I've never really owned one, and only used it few times. I'm intrigued about its graphics and sound, and being able to use 16-bit registers. I'm used to programming in BASIC on Commodores, and would like to use a similar setup, but playing with a 2gs emulator, I'm a little confused.
