Re: FREE Electronic Components !!! - no, this isn't spam !

Anything in DIP packages I would be interested in playing with.

I've not seen a 68k since the QL days.

Re: Help with determining publish years for 198x

Again I have some of these ,but they're a very unhelpful set of tapes here:

Arcadians - no date on the tape, or in game.
Formula 1 Simulator - no date on the tape
Soul of a Robot - no date on the tape

Re: Help with determining publish years for 1983/4

I've a few of these,

Agrovator - no date on tape or inlay
Colossal Adventure - (C) 1983 on the tape
Doodlebug Destroyer - no date on tape or inlay
Draughts - (C) 1983 on the inlay
Edasm - The manual says (C) 1984
Lords of Time - (C) 1983 on the tape

Hope that helps

Alas none here to speak of, I'm afraid. Most of the parts I have came in tubes or bags.

Re: Hardware and Firmware Errors and Bugs

I've been playing with an automated dis-assembly of the MTX Roms, and comparing that to the rom listings from Andy's site, and I think I've found a bug! At 018fd in the listing, where RST 10 is being used prep VS 7 before the system prints error messages, is the following code. SYNT11: PUSH AF SYNTA...

Re: MTX Serial port schematic

The PAL equations for the serial port are on Pg249 of the "Phoenix" manual. They're for the Full RS232 and interface, but I doubt the DART enable changed for the RS232 only card. /darten = /A7 * /A6 * /A5 * /A432 * /IORQL * M1L A432 is formed on the RS232 board (4 input NAND IC9?) and is low when A2...

Re: Sort of based on Magrom

Yes it's doable. Here's MAG2ROM the quick and dirty hack I've put together. There are 15 short games in the image, and a loading screen I had pre-written for a 128k MAGROM. It uses 300 odd bytes of high ram (at 0F900h if anyone's interested) and so could cause issues on larger games. Only lightly te...

Re: Sort of based on Magrom

I wonder if the MAGROM software could be tweaked to run in a regular 16 subpage x 8KB ROM 2 card. If so, would run in MEMU and REMEMOrizer without modification. I'm thinking a ROM 2 card with 16 subpages probably could be a 128KB ROM, GAL and latch. It probably could. Most of the 8k rom space is ta...

Re: Website Search Engines

Can you control which 50 pages it indexes ? If you can then maybe you can get it to look at the "title" and "chapter" type pages. So if someone searches for "VDP" it might not give them the page "This is how the VDP works", but it could find the link on a "How the hardware works" page that says "Cli...

Re: Emulating Hardware Add-Ons

That depends on how many hardware devices that you and Martin have in the pipeline The latest thing I've made, the external Rom2 board, Andy already has in Memu. As much as I would like for him to program in a 6502 co-processor emulator,(to make writing the driver software easier). I don't think th...
