  1. Wizardry was ported to the IBM PC, C64, NES and many other computer systems. I doubt that all of them had a Pascal runtime available to compile code suitable for each system.

    Actually, UCSD P-System was available for the IBM-PC at the original Ship Date... It was the Third OS available for the IBM-PC, after CP/M-86 and PC-DOS v1.00.

     

    ( Remember that PC-DOS was shipped with the Machine and Included in the Cost, where as CP/M-86 and the UCSD P-System were an extra cost.. Look which one Won Out... )

  2. I desperately wanted a Coleco Adam. It looked like a real computer. It ran ColecoVision games! I was so set on it. My parents got me a Commodore 64 instead, likely on price but also Coleco had serious issues shipping that first Christmas season. Regardless of the reason, it turned out my parent's random purchase was the better one in the end. I would have been so sad not having any games to buy at the local computer store with an orphan system like the Adam. The c64 had a huge community and support. It worked out better than the computer I wanted would have! And I loved the c64 after using it.

     

    My Uncle bought an Adam, and had to return it to get another, before finely getting a C64.... ( I still have a set of Adam Manuals )

     

    Your Parents got the better Computer to begin with...

  3. I've spent some time collecting Atari and Commodore items and now have the Apple bug. I've started doing some research and would appreciate any help folks are willing to give on purchasing a system.

    Glad to have you On Board.... I have been a long time Apple ][e and Commodore SX-64 Owner...

     

    Do you prefer the IIe, IIc, IIgs or something else and why?

    The Original White Key Keyboard ][e is my first Apple ][, so it's my favorite...

     

    Each System has advantages and disadvantages..

     

    The ][e is expandable.. Most ANY Card developed for the Apple ][ & ][+ can be used in the Apple ][e.. There are a few exceptions, dealing with Timing Issue of the Address and Data Bus..

     

    The //c is Portable, the Non //c+ has an external Power Supply, and runs nicely off of a Battery Pack..

     

    The ][gs is almost 100% Backwards Compatible with a 128K Apple ][e or Apple //c, but in ][gs Mode, has More RAM, Better Graphics Modes, and the Ensonic Sound Chip.. It also has Built in RGB Output that works in all modes..

     

    If you could start off with one system, which one would you buy?

    If Space is an Issue, the //c or //c+, or a ][gs...

     

    For Expandability Options, an Enhanced //e - Platinum //e

     

    What is a reasonable price for a full system (color monitor, dual drives and computer) in good cosmetic shape?

    Shipping a System with a Monitor, and having it arrive in good Shape will require Good Packaging and will cost a little more...

     

    I haven't priced any systems recently, but I believe that an Enhanced //e with 128K and a Monitor and a Couple Drive is going to be $150.00 to $200.00, plus shipping on eBay.. I would check Craig's List for better deals locally... Or ask on this Web Site or at AppleFritter.com or the Apple ][ Enthusiast Facebook Group..

     

    Is there anything that I should avoid?

    If you don't want a Fix or Repair Project, try to get a System is Known Good Working... All of the Switching Power Supplies in the ][s are know to have Capacitor Issues, especially the Power Conditioning ones.. They are all repairable... Other Issues can be fixed too.. A common issue with these systems not Booting , is there is Oxide Build-Up between the Chips and their Sockets.. Meaning that a Non-Working System might need to have ALL the Chips Pressed back into their Sockets..

     

    ( I got a Non-Working Tandy Color Computer 1 like that.. After the Chips were Reseated... )

     

    Thanks in advance.

    Your Welcome.....

  4. Did Alien Downpour come out? It was supposed to be out April 16th 2017 but the page has not been updated.

    Michael is just Finalizing it... He has reached the Point that DOS Has to Go...

  5. This is really weird. My IIGS worked fine up until a couple of months ago, when it suddenly decided to stop recognizing any i/o device other than 5.25" drives. It's definitely the computer; it recognizes both physical 5.25" drives and emulated 5.25" drives, but neither real nor emulated 3.5" or smartport hard drives. It does give them power, so I can eject disks, but it just won't attempt to read them and says no device is connected.

     

    I've checked my slot assignments and they're all set to defaults. So slot 5 is the smartport. Doing a PR#5 from a prompt also gives me the "no device connected" error.

     

    I thought I might have a dry solder joint on the connector itself, but I just remelted all of them tonight and there was no change.

     

    Any ideas?

    This sounds familiar, but I don't recall what the Issue might be...

    Any help is appreciated.

     

    In the meantime, does anyone know what I can use as an alternative monitor? I have a couple of Commodore 1702's and a 1902A.

     

    Thanks in advance.

  7. My First computer experience was the Apple ][+s at my High School in JAN-1982.

     

    My Dad and Uncle bought Sinclair ZX-81 kits in APR-1983 and I helped assemble them.. So that was my First Home Computer.. ( My Dad's ZX-81, Front Left, My Uncles ZX-81 Front Right )

     

    But I missed the Apple ][, so my friend Randy and I went in 50/50 to get a 6 month old Apple ][e in NOV-1983.. So I got the Computer I wanted, pretty early on..

  8. First, I am delighted this forum exists, and that the TI99 is getting new hobbyist made hardware. Its fun. Second, I am a grey hair whose first computer experience was learning a bit of BASIC on a TRS80 in 1979. While its special, the ubiquitity of the Apple units in school and Commodore at homes overwhelmed it for my set of nerdy friends in the early 80s.

    Apple made Great In-Roads into Education, and the Price Point/Features ( and the Openness of Programing ) the C64 made it Very Popular for the Home..

     

    Its a good point on the Apple units not being as popular as the numbers exposed to it might suggest. Is it because TIs and Commodores work well on CRTs, but I associate Apples with needing a monitor? Or is it the association with education versus games?

    The Apple ][s did not ship with an RF Adapter, it was 3rd Party ( dodging FCC Regulations ), but it was easly added.. The Apple ][s default Video was NTSC Composite.. If ALL Else Failed, you could connect it to your VCR's Composite Video Input and use the VCR's RF Output to your TV...

     

    I am a long time Apple ][e owner, NOV-1983, and I would occasionally disconnect the Apple Monitor /// and hook it up to the Color TV..

     

    In recent years, there has been a big interest in people getting the old Apple ][s, because they could not get one BITD.. Basically First Time Apple ][ Owners...

  9. Sorry for arriving late to this party. I'm pretty experienced in doing DHR from 6502 assembly. If you have any specific questions feel free to ask me.

     

    I addition to what whiteplanet asked, do you have any tools you use for creating DHRG Sprite Images or other kinds of tools??

  10. So the $4,000 was probably a mistake in the posting.

     

    Anyway, since this topic exists, here's a real asking price for a Rev 0 Apple II,

    I withhold judgement because this is almost museum quality except for the damage noted.

    Only funny thing I have to add is that the last 3 (not the original ones I listed in my post) that have been sold on eBay were all sold by Richard Dreher the designer and guy that runs the page that makes/sells/distributes them. I Hope what is happening is that a new run is coming up and he is just selling off the left overs (that he keeps for warranty work) to fund the next round of boards. All of those also sold for more than 300$.

    WOW!! "What the Market will Bear....."

  12.  

    Personally I believe the Steven Ciarcia board and the Super Sprite Boards are "Prior Art", and there is a "Possibility of Software", already written to take advantage of them.. So any New Hardware should be Backward Compatible...

     

    The F18A was made for the TI99/4A, so it has a Different heritage, but that doesn't mean it's not valuable..

     

    IIRC, the F18A is an FPGA, so it might be possible to get some Changes or Additions made to it..
