Anyone have success making backup of Avalon Hill games?

Submitted by old_hitech on March 28, 2021 - 9:26pm

I was finally able to get a a working version of Avalon Hill's Tournament Golf. The game works great.  I have not played this game in 30 years. I am trying to make a backup copy with Copy II+ 9.1  on my Apple IIgs and am having no luck. I have tried the 5.25 BIT copy with the Auto Copy selection and TRY AVALON HILL, TRY STANDARD, TRY  STANDARD (ALT. 1), TRY SUNBURST, TRY SYNC, TRY SYNC (ALT. 1)  and all have failed to make a scuccessful copy. Has anyone had any success making a backup copy of any Avalon Hill games?

Trouble Running ProTerm 3.1 on Apple IIe Enhanced

Submitted by JeremyW28 on March 28, 2021 - 3:01am

Hi,

I recently got a WiModem232, and have been very excited to use it with my IIe Ehanced (It was a regular IIe that has been upgraded using the ReActiveMicro IIe Enhancement kit).  I have been hearing a lot about ProTerm v3.1, and it seems to be the go-to terminal program for the IIe, and one that many users of the WiModem232 have had good success with.  However, I have not been able to get ProTerm to run on my machine.

Apple 2+ No power problem just warm chips

Submitted by AmusedButler on March 27, 2021 - 9:37pm

I have been working on an old Apple 2 plus, got a new power supply and it’s all hooked up. I was trying to test the monitor with computer but no luck and the motherboard was warm, most of the ram seemed warm as well as some rom chips I can get thermal pictures/temperature if needed. Has anyone else had this issue? Is there any way I can fix it? I will try a different monitor but expect the same results.

 

 

 

Thanks in advance.

Apple II+ power issue (not supply) --> Hot chips

Submitted by Stargeezer on March 27, 2021 - 3:37pm

Hi All:

I am still troubleshooting an Apple II+ that appears to work fine w/o periphreal cards but gets wonky video when cards are in and no life in the cards.

I started doing some simple non-invasive assessments.  I discovered I have 2 chips that are getting significantly hot compared to all other chips, one is Apple ROM E0, the other is an SN74S195N.

Two questions:

1) Is this normal for these chips?

2) I have heard about DIY ROM replacements by burning your own on an EPROM.  Anyone done this and had success?

Thanks

mark

Apple IIe Color Monitor issues

Submitted by joel_graff on March 20, 2021 - 7:14pm

Some time ago, I acquired six Apple color monitors of the AppleColor Composite Monitor IIe and Color Monitor IIe varieties.

 

Of them, two work well, two have completely desaturated images, and two have failed motherboards (one trips the circuit breaker when it's turned on, the other just shuts off shortly after turning it on).

In any case, I'm hunting for resources to take a shot at repairing these.  Are there any available schematics?  I'm not having any luck finding anything...

Apple IIe spacebar

Submitted by Wizard1969 on March 19, 2021 - 7:51pm

Could someone walk me through the steps of putting a spacebar on a IIe? I am confused as to the metal bar, do you thread it through the holes in the black tabs in the space bar first, then try to put the spacebar in (seems too easy to drop the metal bar into the case, difficult to snap it in place), or do you snap the metal bar into the keyboard then try to thread it through the holes in the black tabs (can't see anything)?

Applesoft ROM Card vs. Apple Language Card

Submitted by Paul19804 on March 19, 2021 - 4:09pm

I am resurrecting my Apple II (A2S1-9214) from late 1978.  I used it extensively and cut my code writing teeth on it in the early 1980s, but it has been dormant since then. 

It Boots into Monitor; Ctrl-G gives me Integer Basic (I replaced the F0 ROM); C600G starts the 3.3 System disk.  I can load and run Integer programs from there.The problem is the Applesoft (FP) ROM card has gone dead.  I pulled all the chips; deox'd them; seated everything; and all I get upon boot is a totally blank white screen and a hung system.

Apple 2 Plus Power Supply Clicking [HELP]

Submitted by AmusedButler on March 18, 2021 - 3:11pm

I have been reading for some time now about why this happens. I have found no resistors that could be suspect. I have replaced the capacitor with the one they have suggested. When I power it on without any load it makes a chirping noise. IS there a way to fix this? I can send Pictures if needed. I found the old apple and wanted to fix it but the powersupply went boom and smoked when I tried to power it up. I replaced the RIFA cap that exploded. I ahve a AA11040B model powersupply. I attempted to measure the power supply voltages but they were way off!

2513 char gen / 2716 eprom adapter issues

Submitted by blindowl on March 17, 2021 - 1:20pm

Hi, I have a II+ rev. 4 with a Swedish 2513 character generator that I want to replace with an English character ROM. I've built a little adapter board so I can use 2716 EPROMs (or actually 28C16 EEPROMs), using this PCB as a template: https://oshpark.com/profiles/Benchoff

 

Everything works fine except the first column of pixels is always black:
