The Mario Bros XE cart isn't going to work on the 400, for these two reasons: The banked region is in the right cartridge address space and with the byte values as they are, OS-B will jump to low memory at $140D from the address at $9FFE-$9FFF. The XL OS doesn't initialize right cartridges so it doesn't have this problem. The game itself uses memory between $4000-$7FFF. So on an un-expanded 400, this is a memory hole. If you had 32K it would work, but you still have problem #1 unless you patch the OS. How do I know this? I spent 5 minutes with the Altirra debugger. Given your visionary attention to detail, I think if you partner up with Ray Jackson between the two of you we could have an entertaining software porting renaissance for the 5200 and the 400.

My reworked MIO firmware works on either 256K or 1MB devices as it auto-detects the memory size. The ICD ROMs were hardcoded for specific RAM sizes.

I would immediately ask for a refund for the damaged mylar that was carelessly packed and post in the bad trader thread. 🤣 Glad you got it squared away with something simple.

The problem with this thread is that it opened up in an accusatory tone with passive-aggressive posturing of attempting to strong arm a particular outcome with threats while trying to portray one party as the victim and the other party as the perpetrator. This should have remained in personal messenger; I simply responded firmly and held my ground because unfortunately what I have learned now is that I am the second person to have this exact same issue with this buyer. The OP has apologized and I walk away from this transaction. The buyer is being made 100% whole thanks to others in this community with a high sense of integrity, all while I walk away with a loss but at least the machine will go to good home. I'll leave it at that.

I stand behind this transaction. I offered you a $30 refund to replace the mylar, which is a known failure point on these keyboards. YOU AGREED and asked for $30 back. I sent the money via PayPal FRIENDS AND FAMILY because "I didn't want you to get screwed over", what a nice guy I am. End of story and transaction. Apparently not, because you have an axe to grind and have buyers remorse. You got a working 65XE shipped for $70, which is an extremely fair price. The machine was tested 100%. I tested it, and I absolutely know how these machines work along with the foibles being of this vintage and it was advertised as such. No scam, no tricks. Just good honest-to-god description of what was being sold in good faith. You consider it non-working because three keys don't work, and I sent you the link to the resistor fix AND money to replace the mylar. So now you want to change those terms and demand a full refund. This transaction was littered with red flags and it gave me pause and now I understand why. Allow me to add some color so the other folks can understand where I'm coming from: "Does this have S-Video" and "Can this run 800XL software"; your first questions. So, that immediately established that you are not familiar with these machines. But yet you question my thoroughness in testing the machine. Every key and port was checked. Do I need to provide a certified Hi-Pot passed burn report to make you happy? I've sold other machines with no issues here. You wanted to me throw extra things into the deal (low value cart). That's not what was included and the machine was already packed up. So from the on-set you attempted to dilute the value of my sale. I'm not a bad guy for not wanting to tear the box back open that wasn't part of the original sale. Within MINUTES of you paying, you started blowing up my private messenger asking for a response and how you're nervous about sending strangers money. That's funny, I'm nervous about sending vintage computer gear to people who don't know anything about them and hound for a response right away. I mean it's not like a have a full-time job or anything. Within minutes I sent you the tracking number. And now I'm rewarded with this nonsense and the expectation that I provide support for every single question with a 15-minute SLA. You're not being set up. And your post count has nothing to do with anything. You bought an old machine, it wasn't 100% as expected, went to the forum to validate your suspicion of me and instead got the answers you don't want. No one here is viewing you under a filter. You claim out of respect you didn't want to say my name but I'm not ashamed for anything, because I did nothing wrong. I'm sorry the machine didn't perform leaving my high-humidity area to yours. But it is an easy fix, and any amount of research into the matter would have yielded the answers you have been given. I don't want the machine back because to be blunt, I don't trust your skill set working on this machine. You can't make everyone happy but in no way can you frame this that I screwed you over.

Sure, go ahead. It won't damage my reputation.

This unit is now sold.

This unit is still available, the other referenced is not.

I have a testing and working 65XE for sale in good condition, the keyboard has slight yellowing on the left side but not that noticeable. There are no cables or power supply included. $100 with UPS ground shipping included. Domestic US. I also have another one with no yellowing in this thread: https://forums.atariage.com/topic/347031-fs-ntsc-atari-65xe/

Two comments on your design, and this may or may not be the solution but may give you some additional considerations as you expand your use case: - You are gating HALT directly. The HALT signal is not synchronized to PHI2 and if you're generating addresses with this they will not line up correctly between CPU/ANTIC. If you want to differentiate with an ANTIC cycle, register HALT on the falling edge of PHI2 and use that as your enable instead of the signal directly from ANTIC. - All writes to PORTB should not always write to your output register. Remember the PORTB address is multiplexed to two different internal registers on the PIA, DDRB (direction register) and ORB (output register). When bit 2 of PBCTL is 1, writes go to the output register otherwise they go to the direction register.

Price reduced.

Sold!

I have a tested and working NTSC 800XL for sale in excellent condition. There are no cables or power supply included. $135 shipped with UPS Ground. Domestic US only.

This is sold and is no longer available.

The Cindy comment was several orders of magnitude less distasteful than you trying to parade a parody video where you fantasize Hitler is pissed at Cindy for letting your career go no where. The irony here is that you thought that was tasteful when in fact under the policies of the regime at the time you would have been considered untermensch and summarily executed simply for having a mental disability.
