Amiga User Group News / Next SCCAN meeting - Saturday, Sept. 20, 2025
« Last post by RobertB on September 14, 2025, 12:43:14 AM »
Happy Positive Thinking Day, C= and Ami comrades!
     The next meeting of the Southern California Commodore & Amiga Network is Saturday, Sept. 20, from 2 to 5+ p.m. at

  Panera Bread Restaurant
  19662 Nordhoff Street
  Northridge, California
  (818) 407-9400

If I seem a bit loopy, that is probably the result of jet lag.  Please forgive me.  :)
     For discussion we'll talk about the HomeComputerMuseum (an official Commodore museum), the recent HCC Commodore Meeting (Netherlands Commodore Show), the recent Swedish CommodoreTraffen meeting, the recent Amiga North Thames meeting, and the upcoming Bay Area Maker Faire, Rocklin Maker Faire, and Amiwest Show 2025.  Naturally, we will talk about the new Commodore Corporation (nearly 9,800 Commodore 64 Ultimates pre-ordered, as of today!).
     In hardware/software, we'll look the Freeway Pro Lite USB board for big-box Amigas.  Also we'll have the A600GS, newly updated with Amibrowser.  Maybe we can get it connected to the wi-fi in our venue!  :)  Also the Ultimate 64 returns, also newly updated and having the latest game software.
     If you have any software and/or hardware that you'd like us to see, bring it along!

Hey everyone!

Hoping someone might have a suggestion on what I can try next to identify the cause of this strange issue.

I have an A1200 (recently recapped) and a Blizzard 1230IV with 64MB fast RAM. The Blizzard with fast RAM was purchased online recently.

This is all running like a dream - very stable, performing nicely, passing Amiga Test Kit tests and meeting expected benchmarks in SYSINFO.

I noticed though, that the seller sent the Blizzard with one jumper and it was placed in the most poorly-optimised possition - to disable MAPRAM. There was no jumper on the RAMSPEED, thus setting 70ns even though the RAM can handle 60ns (I found this based on the chip markings: https://ram-co-shop.de/64-MB-EDO-RAM-72-pin-Simm-non-Parity-60-ns-5V-Chips-8x-8X8E-43VDW-SS_1).

Strange right? So I moved the jumper to enable MAPROM and set RAMSPEED to 60ns.

Amiga booted well, I ran SYSINFO and got the expected boost to around 9.8MIPS for the RAMSPEED change to 60ns. Ran memory tests and all good. Fast RAM reading reduced to 63MB as expected from MAPROM. Happy days I thought.

Unfortuantely, there is the issue in the title; any soft reboot with MAPROM enabled will lead to crash, pretty much immediately (before the flashing blue lines for the Blizzard would show) with a bright magenta screen!

I've tried many things, including reseating the Blizzard and the fast RAM, but unfortunately not having any luck to solve. It happens on any soft reboot whenever it is done, even if I boot without the hard drive connected. It means I can't use Blizkick so it is bothering me... I really want to to determine if the issue is definitely with the Blizzard before I try to return (as it was sold as tested and fully working), becasue I'm really liking it otherwise.

Any help appreciated, thanks!

Have a look here to download the manual:

https://bigbookofamigahardware.com/bboah/product.aspx?id=151

Secondly, download and run AmigaTestKit and check the RAM is okay on the card. Also try switching back the jumper for the 60NS to 70ns just incase.

AmigaTestKit can be downloaded here:

Amiga Events / Less than 2 weeks to the Bay Area Maker Faire!
« Last post by RobertB on September 13, 2025, 03:16:28 PM »
     Join us and the tens of thousands attendees at the Sept. 26-28 Bay Area Maker Faire in Vallejo, California!

https://bayarea.makerfaire.com

Our booth is called the Classic Bay Area Computers! (CBAC!). I've decided to bring the Ultimate 64 with all kinds of new/old games, the Amiga 1000 with Firebird accelerator or Amiga 500 with Wicher accelerator, the AmigaOne A1222+, and a Toshiba T3200SX giant laptop!  My other friends will be bringing in their machines, anywhere from Tandy's to Mac's to rare Japanese computers and/or game consoles.
     Though location not confirmed yet, we'll probably be in one of the Coal Shed exhibit buildings.  We'll be setting up on Thursday afternoon, and then the BAMF attendees will pour in on Friday, Sept. 26. It will be a long weekend! ;)

Thank you for checking. I can't remember my original account name. I remember I didn't follow the steps to keep it through the transition to the newly hosted Amiga.org site.

If it's a hassle no problem. Thanks anyway.  8)

I am confident this person either has what you need or get it for you. I am not related to the seller, but they've always treated me with excellence. Good Luck!

It seems the wait time is approximately 3 months from order to delivery.
For some. Ordered mid April here. Nothing yet.
