Glad to help Monkey man.

It does not mute the speaker when you connect the 7-pin jumper cable to J25. Besides turning down the control panel volume and removing the internal speaker connector itself, only plugging in a 3.5mm connector to the jack on the back will mute the internal speaker. Make sure you have the 7 pins lined up properly with J25. Remove you memory card to get a better look if necessary.

Just hover the mouse cursor over the name, and you should get the I-beam text editing cursor. If not, the disk is write-protected.

Try plugging in headphones or speakers to the jack on the back to see if you experience the same. This might help isolate a problem with the sound circuitry or the speaker.

I have now tested the same memory expansion card in a ROM 3. The previous test was done in a ROM 01. Testing starts at bank $10 on a ROM 3 rather than $02 on a ROM 01. The same bank location is marked bad on the ROM 3, $100000. There is a slight difference however. The bad memory report occurred on the ROM 01 during the "Bit Test" of MegaMemoryTester. On the ROM 3, it occurs on "Phase 2 Read" of $100000. The "Bit Test" which starts at $100000 on the ROM 3 reports no error. Should I now suspect the support chips instead of the DRAM chips? Why would it have changed from $080000 to $100000 on the ROM 01 when I reversed the chips? I will continue my research by moving these DRAM chips to a different Apple brand GS RAM Expansion card. I will report my results. Who knows, maybe someone will be interested in this. Maybe someone knows how DRAM chips are mapped into banks. I've got other working expansion cards to use, I'm just investigating this out of pure curiosity. Also, rather than disposing these cards, I'd like to pass them on to someone who might want them in working order.

Control Option Esc actually.

I have a fully populated (1MB) Apple Computer / Apple IIGS Memory Expansion card. Testing with MegaMemoryTester reported, Bad memory word detected, $080000 R $0002 E $0000 This result would not occur on every test iteration, but would occur more often than not. I could not find a reference online to which chips belong to bank $08, so I tried relocating chips to see if I could narrow it down. I reversed all socketed chips. (Chips UA1 through UA8 are soldered) That is, UA9 was swapped with UB16, UA10 with UB15, etc. Now MegaMemoryTester reports, Bad memory word detected, $100000 R $0040 E $0000 So, reasonably, the bad chip was relocated from bank $08 to bank $10. There are 32 chips on this board. Bank $11 (decimal 17) *might* be UB15,UB16, or it could be UB1,UB2. Assuming UA1,UA2 is the beginning bank of expanded memory, which MegaMemoryTester starts with ($02), then bank $10 should be UB13,UB14 or UB1,UB2. But I've swapped pair of chips all the way from UA9,UA10 through UB15,UB16, and I will always receive a bad memory at $100000. Is there any logic to bank mapping? Or are memory banks interlaced somehow through these two rows of 32 chips?

Zany Golf is an example of a full-featured GS program based on the ProDOS 8 OS. I agree with you on GS/OS.

That FloppyEMU is an entirely elegant way to transfer disk images between the PC and the IIGS. You will come across many copy protected games that simply will not run, but also many cracked versions available from asimov. You will find many 5.25 inch images that will insist on running only from slot 6 -- they were essentially hard-coded in the early days -- but I'm getting ahead of you. There is a lot of material to be enjoyed thanks to asimov and http://mirrors.apple2.org.za/ Wishing you much fun!

So the $4,000 was probably a mistake in the posting. Anyway, since this topic exists, here's a real asking price for a Rev 0 Apple II, http://www.ebay.com/itm/Early-1977-Apple-II-Rev-0-w-white-MOS-6502-Processor-no-plus-Mac-1-I-Steve-Jobs-/252783664629 I withhold judgement because this is almost museum quality except for the damage noted.

I'd get a second machine and do different things with each, rather than trying to do it all with one.

An Apple II logo plate for >$4,000 on eBay. http://www.ebay.com/itm/Vintage-Apple-II-decal-logo-name-plate-OEM-New-/172590938837?hash=item282f38bad5:g:riwAAOSwXYtY1GQu Get The Hell Off My Internet

I didn't want to get my name involved, but I'd want to know as a buyer, so I gave the seller the story, who responded with a "thanks for the information." Doing what we can for the common good I guess.

I reported it as counterfeit several hours ago and eBay still has it listed.

If this is true I'll be glad to report this to eBay as a counterfeit item... but I must be absolutely sure. I'd give the seller the benefit of the doubt if (s)he indeed did receive it from a collector as a legitimate item -- I'm not looking to get anyone in trouble.

Super Game Module SGM Colecovision Opcode "Juice Box" What is this exactly? One of the previous versions of the SGM or a prototype? What does it/doesn't it go? http://www.ebay.com/itm/262890244447?_trksid=p2060353.m1431.l2649&ssPageName=STRK%3AMEBIDX%3AIT

And Blaster. I imagined Prometheus would ship with DKA, like the original shipped with DK -- and DKA could be free for those with SGMs that don't buy Prometheus -- free, as in a reduced price to cover cost of materials and shipping.

I found the "APPLE ][ DEALER SERVICE PROGRAMS" ftp://ftp.apple.asimov.net/pub/apple_II/images/disk_utils/diagnostics/Apple%20%5d%5b%20Dealer%20Service%20Programs.dsk which tests the F8, and it passes.

Thank you for the emulator idea. It is a good comparison. XPS diagnostics only tests the C0 and E0 ROMs. I will keep looking for a diagnostic tool that is more comprehensive.

Using "Master Diagnostics IIe" (Diags2E.dsk from http://apple2online.com/web_documents/diags2e.zip)performing the "Motherboard ROM test" I receive "F8 Rom Sec is BAD". I assumed this ROM was contained in the EF ROM chip, and swapping the chip with one from another board (same ROM part 342-0134-A) results in the same error. The motherboard is a 1982 unenhanced Rev B, original chips. I could not find documentation for "Master Diagnostics IIe". Might this ROM code be located in another chip? In case of a false positive report from this software, is there another utility known to test ROMs comprehensively? Apple's "Apple IIe Diagnostics, V2.1" doesn't report an error during the "ROM/ CPU Test". The system otherwise operates normally, except for the random wonky lock-up or dump to the monitor.

Project Prometheus reminds me of the Apple IIGS. GS stands for Graphics and Sound. The 8-bit Apple II had been upgraded along the way up to the IIe Platinum, but a leap needed to be made in architecture to go beyond. A significant attraction was that it was 100% compatible with all previous Apple II software (more like 98% in reality). The Apple II line -- the fun computer -- was retired by Apple in favor of the Mac to compete in business computing. The Adam was something of this sort, with an approach to education... but the overwhelming desire to keep it as an expansion module didn't work too well, especially since the video was so limiting. That old video chip, as innovative and affordable as it was, is a serious challenge to work around.

I believe I understand the reasoning for this decision, and it is a wise choice in my opinion. I am glad that there will still be SGMs produced, and will be glad to finally get one.

Over the years, nostalgic thoughts would turn to my Colecovision on occasion. I purchased a cheap Colecovision clock in the early 2000's on one of these nostalgia seeking trips. I happened across a Colecovision flashback in my local grocery store a year or two ago and had to have it. It's still unopened in my closet of yesteryear -- along with my well-preserved collection of ancient technology -- which includes my beloved Colecovision that I bought with the proceeds of my first job, and all the expansion modules I could afford. Just recently a friend of mine posted a photo of his workspace, which included the same Colecovision clock. I had made an impression on him, and now he on me. This last nostalgia trip landed me here, amazed at what I found -- Opcode producing items that I have very often thought of as possibilities. The enormous community here of similarly-minded people astounds me. Here is Opcode, CollectorVision, and Team Pixelboy perfecting the magic of real games when they were artistically genuine and actually fun to play. It's all about colors, sound, and not overdone exposition. I am embedded here along with you all, and looking forward to getting my own SGM. The first game I must have is the new Donkey Kong. Please remain inspired!

I am just an observer because I'm only on the SGM v4 waiting list, but have observed the seemingly common component as the F18A as another pointed out. If this issue might be power-related, as also suggested, perhaps try moving the sprite jumper on the F18A from 32 pixels to 4 as a test?

The reason some of us are subscribed to this topic is so we can learn when the next run of the SGM is available so we can finally participate in this awesomeness. In the meantime, we're just watching everyone receive theirs, and hoping one day we can join the cool kids.
