    Sounds like a good fix. FYI some of the ‘no solder’ memory upgrades from the 80’s used a board with pins that wedged themselves between the chip and the PLCC socket. These types of upgrades gradually bent the chip pins so they no longer made good contact with the socket, resulting in an unstable computer that crashed frequently.

    I reviewed the zuluscsi.log and noticed parity was enabled. This is a problem for Atari ST systems, so I created a zuluscsi.ini file with EnableParity = 0 i rebooted and ICDformat was able to format the drive and it’s partitioning now.

    Got the standard ZuluSCSI installed and it created a 1732 MB image called HD10.img. ICDboot.prg sees the image called ZuluCSCI at ID1 along with the Syquest at ID5. However ICDformat.prg only offers to format the Syquest cart and doesn’t show the HD10.img. Does your image have the .img suffix or a .hda suffix?

    Thanks

    I purchased the standard RP2040 ZuluSCSI to install in my dual drive case. I’ll be using ICD software on my computer that has TOS1.4 and was thinking of partitioning the SD card into (8) 31 MB drives and (2) 510 MB drives, for a total of 1268 MB. The Syquest carts have up to (4) partitions. So I’ll potentially have the max (14) partitions at once. is this a good plan?

    Thanks for the very helpful reply.

    I’m interested in your setup. I also have a case with an ICD AdSCSI+ in it, with a 44 MB Syquest drive and a non-working Seagate HD. What version of a Zulu SCSI do you have (original or RP2040)? Were there any special commands you needed to use with the Zulu SCSI? I’ve searched Zulu SCSI and find no mention of compatibility with Atari ST computers. Does read and write work?

    My statement was just a suggestion about 8 bit Atari’s - nothing more. I have a much broader computing experience than 8 bit Atari’s.

    (Edited) I was right

    All, There was a ? At the end of my suggestion. Then Stephen makes his outrageous statement it’s all a myth. I have had multiple computers made in the 90’s die due to electrolytic capacitors - it’s not a myth.
  11. Forrest
    Leaking capacitors has caused many computer not to work and dissolved solder joints on nearby components. It’s not a myth!
  12. Forrest
    Time to replace the caps? https://console5.com/store/atari-600xl-800xl-computer-cap-kit.html

    Ok, thanks for the update. The author of the PicoMite experienced some instability when overclocking the purple Pico module, but found all Raspberry Pi Pico’s could be overclocked to 252 MHz and most could run at 378 MHz.

    The Atari branded wireless joystick work great with an Atari 400.

    Electrotrains, What speed is the RP2040 running in this project?
  16. Forrest
    That machine looks in good shape. If you want it, buy it. Macs in similar condition are selling for $200-$250 on eBay.

    TBA is only selling the Fixed Fujinet 1.3

    Thom made this same statement to me during his VCF East talk on 4/15/23. Thom posted the link to this talk a few days ago. I just ordered a Fujinet 1.3 from TBA

    I sent a request to the brewing academy last week, asking to buy the programmed OS ROM and Character ROM chips for $20 for the XEP80 II board. They agreed to my request, and added it to their store! FYI they still have the PCB with the NS405 chip for $25 https://thebrewingacademy.com/products/programmed-chips-for-xep80ii?_pos=2&_sid=699274c18&_ss=r

    The Atari XEP80 was released in 1987 (very late in the life of Atari 8 bits) and interfaced thru the joystick port see https://www.atarimagazines.com/v6n3/xep80.html Mytek recreated this project 2 years ago with the XEP80 II. There’s a long development thread on this forum, and details on the completed project on his website https://ataribits.weebly.com/xep80-ii.html

    Use a straightened paper clip inserted into the connector to check with a multimeter

    I’m interested in this project, especially how it integrates with an RGB to HDMI adapter or a GBS8200. How will this project compare with your RGB2VGA-XLD project?
  24. Forrest
    Sorry about your CMM2. I suggest you ask for one on https://www.thebackshed.com/forum/ViewForum.php?FID=16 I was able to get a used generation 1 CMM2 last year for almost nothing - it works great. As a backup, the PicoMiteVGA is a good retro computer that’s programmed with the same Basic, but more limited hardware. It will only cost about $25 to build your own.

    Today, a third version of the PicoMite was introduced - the WebMite https://geoffg.net/webmite.html The WebMite is similiar to #1, except it runs on a PicoW to interact with the web. As with all versions, a full manual (178 pages) is included.
