Re: unknown ST Overscan circuit with 7400

Here is the GB6 result. Reference is the previous bench I did without LaceScan. Notice the resolutions. Surprisingly there doesn't seem to be a speed penalty. Although unsurprisingly now that you think about it.

Re: megafile & scsi disks

On the Megafile 30 you're stuck with RLL/MFM drives. Megafile 44 (SyQuest) can use SCSI drives.

Re: TT issues. Help welcome...

I wrote this in a PM to Anzac but will post here if it helps others. I have 2 extra TT-Ram boards like the one you have. One with the maximum 16MB RAM (4x4MB). I know it works for a fact. Let me know if you want to try it. Many times the TT-RAM connector gets oxidized and there are contact problems ...

Re: unknown ST Overscan circuit with 7400

Thanks :) Good idea on the GB6 bench. I'll have to do that. I get an extended weekend so I'll have time to do it too. Will report back. Yes, LaceScan's software will work without the hardware even on the STE to give a virtual, extended desktop. For use noobs to extra resolutions, if there are softw...

Re: Project STacy

Oh, I wasn't aware of incompatibility with the MonSTer. It's a real shame then.

Are there any other viable solutions for alt-ram upgrades?

I've contacted Darlord and he just replied to me. I'll wait until I get the machines to start playing with them.

Project STacy (STaceX, TOS 2.06 & others)

Greetings Atarians, I've acquired a couple of slightly defective STacy units. I have not received them yet but I know that the keyboards need new mylars and don't work. While I'm waiting for them, I've got a couple of questions. 1. Is there any way to connect a MegaST keyboard to the STacy? 2. Does ...
