Re: Who wants a MAGROM board?

Shhhhh Don't tell Dave, who I've just sent the V4 schematic to, that I I'm looking at doing a V5 board with all these suggestions included. Though for ROM protection would ORing the ROM chip-select with *RE/CPM not be more logical ? that way if the ram only mode is set, them the ROM can never be sel...

Re: Who wants a MAGROM board?

@ Mark, Replacing the 74xx20 and 74xx138 with a 74xx30 and one of the unused gated on 74xx32 seems so obvious now you've mentioned it. The trick with the 74HCT374 and the resistor pack, just shows the huge gaps in my knowledge, I just mirrored the paging system Memotech used. One thing I was curious...

Maybe he's just shy!

BTW Either the copy of Tachyon fighter is corrupt, or it needs to come off that list, I have a proper look at it at the weekend.

Yup that's it, pretty much the "latest" version too. I only ever had one bug report when I had it online, and that was the update with the fix.

Another MTX oldie

Hello! I brought my first Memotech at the end of 1983. Which ended up as a full twin disc FDX. I wrote the "Bomber" game that appears on Dave and Andy's sites (and maybe others) At one time there were 4 of us in the family with MTX's so between us we had a fairly comprehensive collection of software...

Re: Building a replacement MTX PSU - Sneak Preview

I have display issues with both of mine, if the RS232 is fitted, but without it they're both fine.

Re: Easiest way to get RGB out of the MTX?

Courtesy of Andy's Rememorizor: Newword in non document mode for a editor M80 / L80 to assemble and link VDEB for the debugger Not exactly the most modern of setups and a lot of net searching for the syntax later you can write code. If you attach 2 monitors, there's nothing to stop you writing code ...
