Can't seem to find a download link?

All seems a bit complex. Decided to burn the 6 ROM 1.04 TOS and a few mods to the board and all going great! Thanks for everyone's advice.

So I tried burning these ROMs to 2 x 128kb EPROMS and installed in my Mega ST 4. No boot. Note I already have a 2 ROM TOS 1.02 so I figure it's just a replacement right? Has anyone got a working version of split 2.06 TOS fo rhe Mega ST 4?

Hi All, I've bene trying to find the Lo and HI TOS images for the ENG version of TOS 2,.06, I just need the two ROM version. Know where I can download so I can burn with my EPROM programmer? Thanks

So I removed all the mods today and the unit worked but was a bit flakey and would bomb if the 68000 was tapped. I removed the 68000 and found 4 pin which were broken and not the full length meaning their contact with the socket was not great. I built new pins from headers, re-installed the 68000 and the unit is rock solid now. Thanks for all the input.

Hi All, Just collected a Mega 4 today, It's a bit flaky and will crash is it's given a light tap. I need to work out what's going on there. When I opened the unit I noticed a strange mod. I've attached a few pictures. Anyone know what it is. Note that when I connect the yellow and pink wires the unit will not boot. It only boots when they are disconnected. Any thoughts? Can it be easily revered by removing the various wires, desoldering the piggy-backed 74LS74AN and replacing the 68000?

Hi All, I have two Megafile 30's both with dead hard drives. I actually have 3 x MFM drives but they have all failed in some way. Not much chance to salvage I suspect. I was wondering if anyone knows of a relatively cheap solution to replace these drives? I know I can use lots of SD options directly - but I like the looks an feel of the Megadrive so looking to replace the drive internally. Any options?

Hi All, This is driving me insane. I'm trying to make a simple .st or .stx file to load onto a USB stick and work in my FlashFLoppy drive with the HcX software loaded. I've tried the HxC image software but when I copy the .st and .stx files across to the USB stick, the FlashFLoppy doesn't see either images. It's driving me nuts. Is there a simple way o get a few .PRG files, create a simple disk image and load them on my ST via the FlashFloppy hardware? FYI - I'd like to do this on a Mac if possible. Thanks macsonny

It might be the zero track sensor. I literally had almost the same issue today and after replacing the sensor the drive is good as gold. Have you checked that? Easiest way to check is disconnected the connector from the 1050 motherboard and see if you get the same behaviour. If you do, then it's likely the sensor.

Sweet. Have sent a message to them.

Did the PCB or schematics for the Spectre GCR ever get released?

LOL - I like lots of menu functionality - clearly we are opposites!

I use them all. Depends on what I need at any specific time. I wouldn't say there is an ideal DOS for the XF551 as it depends on your needs. Use them all and see which one you like best!

I have a few 8-bit Ataris and I have to admit having chips cream out of sockets was a common issue. Thanks for reminding me 🙂

I got the boards made from the files you posted a week or so ago. Are they ok? Two source files were: Gerber_Mega-Speedy_Mega-Speedy_2024-03-31_Y2 Gerber_Mega-Speedy_display-bez_2024-04-05_Y1
