Also VisiCalc and Lotus 1-2-3 in case @pixelpedant needs an “Electronic Worksheet” fix! Great YouTube channel dude

I haven’t been on this website for a few months: https://www.pcjs.org/software/pcx86/ Dune II emulation in the browser………yeah, I’m going to be real productive today

Answered my own question: >8000 Duplication of scratch pad RAM at >8300 - >83FF>8100 Dup. as above>8200 again>8300 Scratch Pad RAM

Did the QI fully decode >8000 to >82FF? Are they just "four copies" of the same map?

Hi @matthew180 I've been diving into your assembly posts and you mentioned: The value >8300 is used here because that represents the first address in the scratch pad RAM, which exists from >8300 to >83FF (256 bytes.) Actually there is a lot of waste in the memory-mapped devices in the 99/4A and the scratch pad RAM is not fully decoded, which means it will respond to memory address in these ranges: >8000 to >80FF >8100 to >81FF >8200 to >82FF >8300 to >83FF Each range is accessing the same memory, however it is pretty much universally accepted that the scratch pad should be addressed from >8300 to >83FF. Something I've always wanted to do is add real memory to each of those address ranges and give the 99/4A 1K of real 16-bit scratch pad RAM! But that's another day, another project. Would you envision a solution similar to GROMmy where a board would span across the two sockets that held the MCM6810Ps?

Lightbulb moment, Rich. Thank you so much for posting. I'm printing this as we speak. You've got me hooked now... In '92 the only thing I was studying was the manual for my drivers exam.

I've got to be honest here. I've watched GPLHOW2A probably four times in the past couple of years. I've never moved past it because I didn't understand hardly any of it. I just watched GPLHOW2F and am eager to learn more. I really wish those videos were flipped. Or even better, GPLHOW2A redone as a slower version of GPLHOW2F with some explanation of the development environment/tools. Perhaps not a complete program, but snippets of code that shows XB CALLS and statements and their corresponding GPL. The way GPLHOW2F keeps the BASIC commented out above the new code is a great teaching tool.

Some casinos will pay 50-1 for the mini royal but they then pay the straight 5-1, which makes the overall odds worse for the player.

Mini Royal Flush...dealt in order....playing $100 a hand just after buy-in...and Dealer qualifies. Why can't this happen IRL???

I look at it in "tiers": There is the serious "I'm here to win money"/big money tier: Blackjack (0.28% house edge), Baccarat-bet on Banker (1.06%) and Craps-Pass/Come lines (1.41%) There is the "I'm here to have fun, probably lose, but maybe win" tier: Let It Ride (3.51%), Caribbean Stud (5.22%), Roulette-American (5.26%) and Three-Card Poker: even money on all three bets (5.32%) Then there is the "I'm a pure dreamer and am not expecting to win, only want a jackpot": Slots (~10-15%), Big Wheel (22.22%), Keno (25-29%)

Interesting. I thought the ACCEPT AT checked the value and just went back to the same line. I'll have to take a look. Thanks again for the feedback! I found the issue. When I renumbered my subprograms I broke some code that was already tested. The attached version will not allow you to enter a value outside of the min-max values. Thanks again for the catch. *If a moderator could swap this file with the initial post that would be awesome. Otherwise, the only issue is this value check. The game plays fine otherwise* THREECARD

House edge is 5.32%. About equal to American (double zero) roulette. Craps and Blackjack are much better games if you are trying to lose less money. https://wizardofodds.com/games/three-card-poker/

Hi ti99iuc, I'm so happy you are enjoying the game and no problem with adding to your database. Yes: In a real casino, the "Pair Plus" is optional. I took a bit of liberty to make it mandatory to make my payoff algorithm and "Display at" statements a bit simpler. Plus, I figured with fake money, people would want to gamble a bit! I also strategically made the minimum bankroll ($500) at least three times as large as the maximum bet ($100) to allow the main play loop to not crash from the start. In a real casino you could have a bankroll of $1010, put $1000 on the pair plus bet, $5 on the ante and $5 on the play and pray for trips!! If the Dealer does not have a Queen-high or better the Ante bet pays, but the Play bet is a push. The Pair Plus is always in play no matter the Dealer's cards. For the hand you are showing, these are the correct payoffs. Interesting. I thought the ACCEPT AT checked the value and just went back to the same line. I'll have to take a look. Thanks again for the feedback!

For some reason this downloads as executable "HREECARD"...but still works in Classic99

99ers: A few months ago I was looking for an app to play three card poker and didn't find one I liked, so I decided to write it in XB. For those unfamiliar with the game, there are a bunch of videos on youtube: Basic strategy is to play when you hold an Q-high or better and fold anything below that. Even after several hours of free cocktails, you can still maintain perfect strategy ;). This is also one of the only poker games where a straight beats a flush. The three best hands are straight, 3 of a kind and straight flush and the TI-99 will show it's appreciation when you get them. Enjoy! Req: Extended Basic, 32k Updated version: THREECARD

Finally finished my SAMS board (parts delay). Test Sat / no errors. Weller 1010 was an absolute pleasure to work with! No more testing the heat of my soldering iron by licking it 😉

It is very confusing (for me)! The manual indicated that you could use the DB25 serial connection too, but needed a interface box that Royal sold. Not sure if any of those survived.

The three cables from IEC all have the right connections. Now it is just a matter of testing to see if one has the right pinouts

Thanks, Ksarul. I ordered one of each and will report back on this thread after testing in case anybody else is interested in the Royal Alpha 2015.

Hello 99ers, I picked up a Royal Alpha 2015 that I’m going to try and get setup as a printer. Looking at the manual, it appears every period computer needed a specific cable (RS232 to Centronics). Does anybody know if there is anything available “off the shelf” that would have the pin outs of Royal P/N PCUA 013156. I’m assuming I’ll have to make a cable, but doesn’t hurt to check. Thanks!

It even has the original v1.0 dent on top! A very rare option

Heads up: https://www.ebay.com/itm/125474516643?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=Bbq1Ls4SSiK&sssrc=2349624&ssuid=QfU6nnIiRby&var=&widget_ver=artemis&media=COPY

Looking forward to receiving my copy and firing up the dual cassettes! You mentioned Notepad ++. I assume you made a User Defined Language (UDL) and that is how you have keyword highlighting that you show in your videos. Would you consider exporting the UDL for the community to download? Thanks!

As this is a thread about rare items, has anyone ever seen one of these numeric keypads IRL?
