Best Openings for Micro-Chess 2.0; what is its ELO?

Submitted by Timelord on February 13, 2021 - 3:51am

I have been experimenting with some modern openings with Micro-Chess 2.0, that tend to work very well with live play, but the software (from 1980) shocked me in finding creative logic branches to defeat or to blunt them.

 

I am curious if anyone has ever proven its ELO (per IQ setting) and what the best openings to use against its logic tree tend to be. 

 

As far as I am aware, and the manual supports this, the user can never play as black, so this rules out some options.

Possible Apple IIe spanish ROM.

Submitted by Ramirofv on February 12, 2021 - 8:28pm

Hi everybody!I recently bought an Apple IIe with the "keyboard switch" underneath, spanish keyboard and -I guess, help me if I'm not correct- SPANISH video and keyboard ROM's. They are labeled "341-0155 revB" for the keyboard and the video ROM is "341-0165 revB" and is mounted in a small daugther board called "AIIE LANGUAGE ADAPTER" (820-094-A).

I would love to contribute this ROM's to the community since -and then again, this is a guess since I'm not expert-, I can't find any mention of them on the web, so I'm under the idea that are unusual or at least rare.

Hot DRAMs

Submitted by Mr.Fix on February 12, 2021 - 8:03pm

Hey all, i have a apple 2+.  I am having an issue with the onboard DRAM on the motherboard.  I have noticed that all DRAM banks are heating up.  I have checked voltage at PSU, and they are within voltage spec (+-5,+-12).   I have tested the DRAMS with APEX diagnostic software and the results are the DRAMs are good (no bad chips). I have taken out all the DRAMs from the motherboard and filled up first bank, and this entire bank is heating up.  Any ideas on what to check?

2716 Char EPROMs

Submitted by Timelord on February 9, 2021 - 5:28am

I seem to recall that 2716 char EPROMS worked on some revisions of the ][/+ mainboards. Which revisions support that? I do not recall offhand what was changed in the char ROM pimnouts.

Apple IIgs System Bad: 06070000

Submitted by MiguelChavarria on February 7, 2021 - 9:48pm

Good Evening,

I have an Apple IIgs that my father bought for me back in 1987. I set it all up and turned it on and the self test started. It ended up with a System Bad: 06070000 message. Would anyone happen to know what that means, what is going wrong and how to fix the issue so that my Apple IIgs is running normally again?  Thank you I appreciate the assistance.

 

R,

Apple IIe Keyboard Issues

Submitted by zippyedge on February 7, 2021 - 12:10am

Hey guys,

I recently got myself an Apple IIe and IIe Platinum locally. After cleaning the keyboard PCB with 91% alcohol, (1-9) on the keyboard no longer functions, though everything else works. I also tried the keyboard from my IIe Platinum and can confirm that nothing is wrong with the motherboard/keyboard chip. I also have a spare II Plus, that I may be able to get parts from. Any help would be great!

 

Thanks,

George

Apple II IEEE-488 Interface Manual

Submitted by brimars on February 6, 2021 - 8:52pm

I recently acquired an Apple II IEEE-488 interface manual in English (Asimov version is German). Does anyone have an interest? I haven't scanned it yet but if there are interested folks I'll increase the priority on it. Since I have about 2000 projects banked, that should have it done by 2035. I'm actually interested in using it with my IIe Platinum but haven't got the space just yet to hook things up and haven't created the adapter cable for the card...
