This has to be a red flag warning one for an 800, load of photo's of screen shots, could be from any 800. some photo's of an Incognito board, but not a single picture of the 800 itself. In the description he says:- **Some cracks in the casing have been fixed and it's structurally sound. These are around the back so not really noticeable at all. Usual light blemishes and scratches marks consistent with a 40 year old vintage computer. Price has been reduced from my usual asking price to reflect this** I suspect the "some cracks" are more serious than he's saying, not worth the risk for £399.99 https://www.ebay.co.uk/itm/176340555289?

One thing, this does not clear 0 to 255 bytes, it clears 1 to 255 ; Clear Ram Player/Missile .proc clear_pmg ldx #255 ; Erase all the area from 0 to bottom 255 lda #0 loop sta pmg+$400,x ; Player 0 sta pmg+$500,x ; Player 1 dex bne loop rts .endp This will do the 256 bytes, x register is not tested until it's been incremented so BNE still works. ; Clear Ram Player/Missile .proc clear_pmg ldx #0 ; Erase all the area from 0 to bottom 255 txa loop sta pmg+$400,x ; Player 0 sta pmg+$500,x ; Player 1 dex bne loop rts .endp

What version of Steem are you running ? I'm using Steem SSE v4.1.1 R9 and it loads .STX fine

@Trebor posted on Sunday CTRL-J accesses the Downloads Tab, this solution does work

The console register doesn't have a shadow like the keyboard, poking the register address ($D01F) has no real effect other than it's also used to make the speaker sounds on an 800, simulated on XL/XE. Unless one of the console keys is pressed, it always reads 7 regardless of what value is "poked" into it. RESET is not a register, it's hard wired to a monostable mulitvibrator to produce a reset signal to various chips.

Thank you. Though I have to admit I built it initially so I could use a USB keyboard through the joystick port. I did get that working also through this interface (obviously not START/SELECT/OPTION and RESET) On the Atari there was a VB routine that read the keyboard via the joystick port

I used a Sparkfun USB Host Shield https://www.sparkfun.com/products/21247 I don't remember it being that expensive though, mine came with the pins/attached already https://www.sparkfun.com/products/11417 It plugs directly into the UNO and sits on top, I power the UNO via it's USB port, the shield takes it's power from the UNO

Could be a memory issue, the screen can be anywhere which might explain why some are ok.

Strange, this doesn't work for me, even restarted Chrome, but it still blocks the download.

Good idea, but I use the same pad in Altirra on my PC 😮

That would be funny, but illegal unfortunately. Maybe I could take some of the "electric rope" the farmer uses in the field next to me to keep his sheep in and weave it into the gate and hope no one notices, it just looks like red nylon rope, but if you look carefully there's a thin wire woven into it

I made my own with an UNO and a USB HAT, found some generic UNO software examples, I think it was for a keyboard and modified it to read a USB Buffalo Joypad and later added a Sytec Joypad too, works a treat and the UNO is 5V, no need for level shifters, one day I'll mount it in a box

Pin 37 from Pokey to this circuit (SOUND input). The keyboard click comes from GTIA pin 15 and is the BELL input to the audio circuit.

Fair enough, I missed the size of your loader in your comments

Here in the UK most delivery drivers need to take a photo of the package in your hand or they won't leave it, some of the smaller (cheaper) companies will drop light/small packages over my gate, its over 6 feet high and electric, so can't be opened without a remote. And a CCTV pointing at the gate if any ambitious crook wants to try climbing over the spikes on the top of the gate
