Re: MegaST, TOS in 6x 29c256, won't boot

According to PP's page on a flashable TOS ( http://atari.8bitchip.info/flashest.php ), although he speaks of 32 pin packages, 29c256 seems to be a drop in replacement as long WE is high (WE is low active). Checked and 5v is present at WE pin in all 6 chips. It should work, so it seems to point to a ...

Re: MegaST, TOS in 6x 29c256, won't boot

Moded the board per instructions confirmed in several places (remove U12 74LS11N, W2 1-2, W3 1-2, W4 connected) and placed the 6 chips on the sockets in correct position. I did the correct jumper settings and removed the 74LS11N. One thing that has occurred to me was that Flash chips aren't quite a...

MegaST, TOS in 6x 29c256, won't boot

Hi all. I have a perfectly functioning Mega ST 4 which has TOS 1.02 French in 2 chip configuration. Wanted to replace with TOS 1.04 UK. The board is a C100167 Rev 4.0 and it has the sockets for 6 chip configuration. Been reading the posts around here (specially the TOS megathread) and on other sites...

Re: Alternate TT hi/VGA adapter

All the monitors I've tried will scale vertically and cannot reduce size. There will always be some moiré at high res. Best way is either all white or all black background. On the other hand I think it's for the best since old CRT monitors were 4:3 ratio and newer non wide LCD are 5:4, which means t...

Re: Wish we could get this...

I doubt they are 3D printed, most likely someone got hold of the original molds. I can find how much it would cost to manufacture a mold for STf/STe casing, I have a friend who works in the industry here in Portugal and I can have a talk with him. He's a bit overwhelmed with work right now, will hav...

Re: Atari Megafile 30

You need TOS 2.0x to be able to boot from it Why is that? Are you confusing this with an IDE drive? TOS 1.0x can boot from ACSI hard disks very well. (Though I recommend at least TOS 1.04, because several file system bugs were fixed there.) I was convinced of that but since I haven't used my Megafi...

Re: Atari Megafile 30

The Megafile 30 is an external 32MB hard drive for the ST, connected through the ACSI port (grossly put a simplified SCSI port but not compatible). The hard disk inside usually is a very noisy Seagate ST-238R with a MFM interface. You need TOS 2.0x to be able to boot from it, otherwise hard disk uti...

Re: PC mouse mod for ATARI.

I reported the symptoms to Kevin from KMtech, he might have refined the programming of the PIC and make it work since I bought this in October 2015. Might have been the mice I tried it with, though I tried with several that worked ok with my DIY adapter. Don't forget they advertise them mainly to th...

Re: PC mouse mod for ATARI.

I used the Mouse adapter v1.3 schematic in this page to make my own adapter, works fine. I also bough one on Ebay, the only diference is that it acelerates cursor a bit.

As for using an emulator... I don't know. I haven't tried anything like that and only have basic knowledge of the existing emulators.
