#4134206 Sails of Doom, new multijoy game

Posted by slx on Mon Oct 15, 2018 2:50 PM

ivop sold very nice bare boards a year and a half ago, even though they require a lot of soldering I'd say they are rather simple to build. No one seems to sell finished ones even semi-commercially. Would be a nice candidate for Lotharek.

#4132116 Mac/65 Assembler

Unless you want to code on Atari hardware, WUDSN Eclipse is the software to use. Coding is a lot more convenient with a full-screen editor without line numbers and debugging is a lot more fun on a PC as well. 

#4132108 New version of ATARI 8 bit emulator released!

Posted by slx on Fri Oct 12, 2018 1:05 PM


And HOW IN THE WORLD do you think we got Altirra (and other SUPERB work here) up to where they are today? By just back-patting each other and kissing our foreheads?


It would be a DISSERVICE for the Xformer crew not to provide them with a clear perspective of things, as much as it would be to our own community, to which we would also (and indirectly) negate the opportunity to enjoy a stronger, better Xformer…


This notion of "because its free you accept it and don't criticize it" is essentially meaningless and harmful. Sorry to be a rude awakening here, but it is much better to face the truth, as it is, and build upon it a better future, for everybody (devs. and users alike).


Progress only comes out of truthful and real criticism.


Well, reading through the posts again they really don't sound as critical as I felt them to be when I wrote my first post. So my post might have been inappropriate and I do apologize to anyone who might have been offended by it or felt that his post was criticized.


I do not disapprove of critique at all. I do, however believe, that everyone who shares some work with the community is entitled to receive a "thank you", regardless of how small or simple his/her contribution might be.


The community is not entitled to an upgrade but I believe that a "this is good already, thanks for sharing with the community. You can make it even better by adding this and changing that" approach will more likely result in more impetus for the average developer to improve upon his work than just saying  "we need this". Approval and appreciation for work done is a powerful motivation for future work.

#4131792 Size of the Atari 8-bit Community

Posted by slx on Thu Oct 11, 2018 11:38 PM

A lot of expansion options still suffer from less than perfect documentation, i.e. having to search this forum and some blog posts to actually use them. Even a must have like SIO2SD is not that intuitive for someone now used to drag and drop rather than shift backwards, then F3 using unmarked keys.

#4131789 New version of ATARI 8 bit emulator released!

Posted by slx on Thu Oct 11, 2018 11:26 PM

There are reasons to use Altirra and there will be reasons to use the new XFormer, which might, e.g. attract more attention in a display. Star Raiders will be as much fun when played with a slightly wrong shade of galactic map (as a PAL user I can vouch for that, we got slightly wrong colours all the time). I find it slightly harsh to tell someone (who started to give free software to the community quite early) that what he gives us for free is a bit inadequate.

#4131784 The best type in magazine programs

Posted by slx on Thu Oct 11, 2018 11:11 PM

I always like Road Block from Compute! 2K, pure assembly, up to 4 players, variable speed. Managed to enter it with 1 typo and that happened to affect a letter of the title screen.

#4128001 Confusion about 400 vs 800 RAM and games

Posted by slx on Fri Oct 5, 2018 4:05 PM

Yes, but the kit requires cutting and soldering and, thus, is not intended to be installed by the average user. The 400 requires a significant-enough modification such that it would not make sense to label it as 400-compatible when they should be listing the memory requirement instead. Of course, this particular game didn’t actually require more than the base 16k, so that label is correct (in direct contradiction to the box).


I assume most of those 48K expansions for 400s were installed by dealers/service centers back then, so lack of "self-installability" doesn't necessarily make it a fringe piece of hardware. I have not come across a lot of 400s so far, but it would be interesting how many of those around have >16K.

#4114439 Sophia rev.C - DVI board

Posted by slx on Sat Sep 15, 2018 10:55 PM

Does anyone know if the Sophia supports 144hz monitors? Ive been looking into getting one because it looks like they would be better for most of the arcade style games I love on the 5200. Also, does it support DVI-D(dual link)?

Why would you need that? Your Atari cant produce more than 60hz anyway, nor will it use a resolution that would require dual link to send to the monitor. If your monitor supports 144kHz it will happily accept the Ataris 60.

#4113441 POKEY alternatives?

Posted by slx on Fri Sep 14, 2018 12:56 PM

There's a POKEY replacement chip entry in this year's ABBUC contest. Probably overkill for a 7800 as a "sound only" version would probably be sufficient for the 7800, but might still be the future. Details will have to wait until the end of October as there are some restrictions on what you can publish/sell before the contest is over.


Sorry, just saw that there is a thread on this in the 7800 forum already.


Buying a couple hundred of those O'Shea Ballblazer carts back then for a buck each would have been a sound investment....

#4111858 High cost of ATARI on ebay..

Posted by slx on Wed Sep 12, 2018 2:04 PM

I think there are still a lot of guys out there who heard that Apple Is fetched huge amounts and now think their VCS jr or 800XL is worth a ton of money. Not all that is asked is actually paid. Have a look at prices of stuff that actually sold and the picture gets a lot less dramatic. There were a couple of 1200XLs sold for less than 100 USD this summer. Some people keep trying on EBay for weeks before lowering prices, and sometimes they catch a sucker or someone who needs something quick or is too lazy/busy/etc. to bide his time.


I find unreasonably high prices much more of a nuisance on our local Craigslist type site, where some people think they can sell a VCS jr. with three common carts for 150 bucks. When you make them a reasonable offer they're offended. I usually wish them good luck and tell them I might still be interested should they reconsider.


The advent of EBay must have reduced the rate at which old Ataris went to the landfill/incinerator, but the overall number is declining, so even with constant interest prices are bound to creep upwards. Wouldn't consider it an investment yet, though, especially if you figure cost for storage space. :grin:

Night Mission 150.810 (those low bumpers are a pest, a lot of 50K-ish games with many balls deflected by them to be be lost between the flippers. 

Night Mission 150810.jpeg


Choplifter - a meagre 32. I recall being quite annoyed on finding out it didn't continue after rescuing all 64 hostages but very much doubt that I will ever reach that point with my 35 year older reflexes. Maybe I spent more time on it when I had as many games for my 800 as I have kids now....(3). Maybe it's the NTSC speed but I find keeping the chopper in the right orientation a lot harder than it was then and while I have learned to live with the fighters the UFOs are a PITA. This looks a lot more serious than the later adaptation.

Impressive! I'd be happy if I ever go around to do even half the mods to my 1200XLs.

I found a link to this interesting NY Times article on the deterioration of plasticson the HP Museum forum.
