I'm pretty sure that the Apple and the IBM both had 150K Ohm Pots in a Resistance configuration, and the Tandy Color Computer uses a 100K Ohm in a Voltage Divider configuration.. I have Apple ][, IBM and Tandy JoySticks, so I should go and test them all... MarkO

ADTPro works with the Uthernet cards too... MarkO

Hello Boat!!!! Once Upon a Time, "they" made Floppy Mailers, just for such an occasion... The Cardboard Sandwich, describe above is always an option, or even a Cardboard Mailer or one of the USPS Flat Rate Boxes... MarkO.

It could be an Issue with the JoyStick, but if it works fine on the //e Platinum, it is likely an issue with the Non Enhanced ][e... The Apple ][ uses a Tricky Hardware Circuit, that uses a 555 IC, ( actually the 558, which is a Quad-555 ) to Charge some Captors, based on the Resistance of the Potentiometer in the JoyStick, to determine the Position.. MarkO

Some of the Community Updates to ProDOS also removed the requirement on the 65C02, letting them run on Earlier Apple ][s than the Enhanced //e.. MarkO

As recall, ProDOS was made in Two Parts, unlike the original Apple ][ DOS.. The PRODOS ( SYS ) File is the Base OS, RWTS and Higher Level Disk Functions.. The BASIC.SYSTEM ( SYS ) is the BASIC Commands that are Hooked into BASIC.. If your not using any BASIC Programs, you don't need to Load BASIC.SYSTEM, thus saving you RAM for your Assembly Language programs.. MarkO

It would be possible to "hook" the Keyboard Routine to Click the Speaker.. This would Slow Down the Response a bit, because you would need to make an Audible Click before returning the Control to BASIC or your application... MarkO

Can you post the Links to the Archive that has the Technical Docs?? I had a Star Gemini 10, way back in the early 80, and I still have a Star SG-10.. I could probably Dump the ROMs on the SG-10. MarkO

Like the FD-501 ( Radio-Shack Part Number 26-3131 )??? https://www.cocopedia.com/wiki/index.php/FD-501_(26-3131) This is a Floppy Drive Controller for the Tandy Color Computer.. The ROM is MC6809 Code, not Zilog Z80 that the Model 1 uses.. Something could possibly be rigged up, but it might be better to just get the Correct Hardware.... MarkO

Bill Buckels has a bunch of Apple ][ related web sites including this one: http://www.appleoldies.ca/graphics/index.htm You should be able to use GIMP and then Convert as needed. You might look at his other sites as well: http://www.aztecmuseum.ca/ http://www.appleoldies.ca/ http://www.clipshop.ca/Aztec/ http://www.c64classics.ca/ http://www.cpm8680.com/ MarkO

"Vintage" Nope.. Disk looks Too Clean.. "Copy" Yep... For Sure.. Did you see the Other Auctions for Similar Disks?? MarkO

With 74LS125s, you probably should have a half dozen or so, on hand... MarkO

My preference too, but eBay does favor the Buyer, so you do have a lot of leverage when buying things.. Jameco has the 74LS125s for less than a $1.00 each, but I believe you need a $5.00 order minimum.. MarkO

eBay?? Not necessarily.. You can start there.. You should contact Apple Fritter again.. MarkO

Two sites you need to know about for locating Electronics are "Find Chips" and "Octo Parts".. Looks like there are plenty of replacements available... https://www.findchips.com/search/74LS125 BTW, did you ever get an account to Apple Fritter?? MarkO

That can lead to the 74LS125 being Blown Up... I ALWAYS, remove the Disk ][ Controller and turn Upside Down, to plug in the Drive "correctly".. This I learned to do after Blowing Up 2, of the 74LS125s... The Clicking is the Apple ][ Power Supply, shutting down to prevent damage... MarkO

Black Slots but the Raised Power Light... Also, ALL the ROM Sockets are Filled.... OP needs to try to Boot one of these.. MarkO

Can you post a link to this Open Source Project?? MarkO

Here is a Ventless ][ that sold recently: https://www.ebay.com/itm/155253528976?mkcid=16&mkrid=711-127632-2357-0&ssspo=0bIPRHFwS2e&sssrc=2349624&ssuid=DGsb_5zqRmu&var=&widget_ver=artemis&media=COPY&nma=true&si=RSwMW4JdqvTsW7YxaGncZbKGbmY%3D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557 Does your have a similar keyboard?? MarkO

My Apple ][ is dated 7916 and Serial Number 25422... Your Computer might have a Rev-02 MB or Rev-03.. It might halve the original Keyboard Controller... my Apple ][ : http://tech.markoverholser.com/?q=node/11 MarkO

Can you get some pictures of the serial number/ assembly date.. and the keyboard controller board.. MarkO

The early Apple ][‘s Keyboard Controller can be damaged fairly easily... You might have one of these units... MarkO

I didn't realize that the Living Computers: Museum + Labs was reopened.. VCF-PNW was held there is 2018 and 2019, and was scheduled in 2020, until Covid.... MarkO

What Disconnect Signal is Waffle sending to the UDS10?? Can you use the DSR/DTR to control the ON Hook/OFF Hook Status? The UDS10 supports Modem Mode commands with a 1 Second Delay, then Three '+' , with no longer that 1 Second Delay, then another 1 Second Delay. The UDS10 Prompts, "OK", then you send "ATH" and Enter and the UDS10 Prompts with another "OK". This will Disconnect the Session.. ( See Lantronx UDS10/100 Manual, PDF Page31 ) https://www.lantronix.com/wp-content/uploads/pdf/UDS10-UDS100_UG.pdf MarkO

The Mobile Armatron would be much easier.....
