  1. @ rdea6

    Thank you for the hints. I changed the sector size to 256 and things turned great. I now have D3: act as a booting SpartDOS hard disk (SpartaDOS Pro Ver 3.3a 3-Nov-94) :-D

    I had difficult times to figure out how to format a partition (ie, D4:) using MyDOS. It turned to be that "\N" is needed to complete the format. How noob I was. Did not read the MyDOS manual.

    @ phaeron

    Sorry for my English.

     

    I was referring to the "Ultimate 1MB (U1MB) Rom Builder v1.0.4" by (atari8warez) where I was not able to flash the Ultimate 1MB ROM correctly.

    Actually, I did flash the Ultimate 1MB ROM after adding my choice of ROMs correctly using "TheRomGenerator_v1_0_19". by AtariGeezer.

    The save configuration "S" and load SIDE Loader "L" options were already working from start.

     

    Thank you for the Gem program (Altirra) :thumbsup:. Also, thank you very much for the time and efforts you devote into it in order to make it easier for Atari users.

     


  2. While awaiting my U1MB ordered from lotharek, I tried to test it virtually under Altirra v2.5. The following are some of the of findings:

     

    - I was able to install/run virtual U1MB under Altirra using Ultimate.atr from: http://www.atari8.co.uk/apt/ultimate1mb/index.html

    - Used fdisk.com v4.5 to set up FAT and APT (drives D3-D8). ran the "format" command under Spartados x to format D3 only and made it bootable. Copied X33A_50.DOS into it and used boot command to make it the loaded DOS. But if I choose to disable Spartados from U1MB menu, Altirra freezes (may be D3 is not booting from start !!)

    - Made my custom ROMS and flashed them using "TheRomGenerator_v1_0_19". Thank you AtariGeezer

    .

    - Loaded games ATRs into FAT and ran them successfully through side loader.

    - Unfortunately, I couldn't flash ROMs using Ultimate 1MB (U1MB) Rom Builder v1.0.4 by Ray. after flashing, I could see the flashed ROM names, but when I hold down the "L" key, I only get repeated key clicks.

    - I managed to go to basic (solved the issue).

     

    Things I couldn’t manage to do (yet). A helping hand is appreciated:

    - Format any of the HD drives using MYDOS. I only was managed to configure the drives with "R" and make any drive size to 65535 sectors (i.e. 4H). For mating with "I" returns error 139.

    - I had better times using SIDE for virtual hard drive VHD than SIDE2 (as a hardware).

     

    Special thanks you flashjazzcat for the enormous links and subjects about U1MB and SIDE. I learned a lot and still learning .


  3. I only have few disk poxes (games and utilities) escaped from the trash massacre made by my wife for my Atari treasure when she decided to clean the "garbage". I wish I was there on that day :_(

     

    I currently use one 130XE that I purchased from eBay few months back with full blown ram :skull:.(fixed 11 days ago). and one 1050 drive.

     

    I discovered 4 Arabic games in one diskette and an Arabic word editor dumped from cartridges using one 65xe NAJM computer (in aDawaliah) branch in Jeddh, SA around 1989 or so)

     

    I will have a separate thread once i receive my SIO2PC ordered from Ray.

  4. Thank you all for info and suggestions, that I learned a lot.

     

    When I swapped the banks as suggested by Jurgen, I got a black screen (with some twisted grey vertical lines).

    I switched back to the original connections of resistors R110 and R111 and the test ram screen came alive again (all bad except 3 boxes).

     

    I guess that I will wait for the ram chips I did order yesterday and let you know of the outcome. (a simple eBay purchase turned into a project :grin: ).

    Unfortunately, orders take 18-25 days to arrive.

     

    BTW, Almost Rice had mentioned a 320xe ram upgrade. I though it is still a beta project. I would appreciate it if some one put the link.

     

    Regards

  5. Just to add more testing results.

    I turned the 130XE on for 10 mins,then measured the temperature of all chips on board with gun (laser) thermometer

     

    All RAM chips (16) were of normal room temperature (25 +1 or 2 C) except for:

    C014806C (Atari SALLY 6502C) ? and C021697 (ANTEC 'E') ? which are the only socketted chips.
    The temperature of both was 41 C.
    I thought, that temperature goes very high for damaged RAM chips :?

  6. Thank you Kyle for the information.

     

    I opened the 130XE and found 16 ram chips 15 of them marked with µT 4264-20 and only one was marked with m 3764_15RS (OKI).

    I tested the power supply voltage on pins 1,4,6 of the C061982 :( power supply and it read +5v.

     

    It is not clear to me which is the best RAM replacement technique:

    Should I buy the same chip ratings (64k) ?

    or can I replace them with compatible 256K for example?

    Is it possible to mount the new ram chips on top of original ones (piggybacked) to be safer?

    What are the recommended RAM brand(s)

  7. I purchased an Atari 130XE through eBay. When I turned it on, it went directly to ram test . All ram boxes (cells) showed red color except for the box 1, 13 ,21 and 22. when I inserted a CART, it always go to ram test screen only. Is it mainly a ram failure issue?

    If I get a ram extension model such as RAM320XE will be suffice?

     

    Thnx


  8. thanks, Madi

     

    I don't know whats wrong, followed your directions, it still wont work.

     

    I have a 64bit pc laptop, both versions of Altirra run on it though.

     

    im gonna try other Atari wares with altirra...

     

    Be sure to Detach cartridge from "File" menu first like this image:

    Then, you choose the MicroCalc image from "Attach Cartridge.." or drop it in Altirra windows and choose the following:

    Here it is running:

    Good luck


  9. thanks, FULS.

     

    sorry I cant get it to work (Altirra noob)

     

    ?

    Open Altirra

    |Go to "File",

    Choose "Attach Cartridge"

    You get a " Load Cartridge " window. Choose "MicroCalc (Altirra Emulator Only).bin".

    Pick" *MicroCalc 32k " which is the last option (among other options in the Select Cartridge Mapper window)

    That is all
