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:

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.

Thank you! I'll check with him.

I did find the pinout in the manual so I can make one if need be but other sources are always welcome

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!

Putting together my 4000T Toaster/Flyer again and things are working well but there is an issue…. The TBC IV I sourced did not arrive with the Din-9-M to Serial cable. (Attaches to the Amigas Serial port on the back and to the TBC’s round Din9 connector allowing control from the installed software) I’ve been searching the web and so far nothing. AliExpress has a couple listed but I’ve never ordered from them and who knows if the Pinot is correct. So I’m looking for either
A - someone who has one they are willing to part with in the US
B - someone who’s willing to continuity check theirs and tell me the Pinot so I can make my own
C - someone with knowledge of the proper way to install an internal cable to the 3 pin header on the TBC then to the A4000T motherboard if that is possible.
Also looking for an original mouse round plug extension for sale in the US. All I find are overseas vendors.
The photo attached is of the faceplate adaption I made for the zuzuSCSI and SD card extension connector. Works great! As does the Zulu. Except I’m having one heck of a time configuring the wi-fi
