Hello All,

I have a vectrex, and I have a PC, and I know how to program (even in
assembly). But I'm ten thumbs when it comes to working with hardware. I
would love to be able to write code for the Vec, but have only a
general notion of how to proceed.

I know I need an eprom emulator, and I have found one at Wiltronics in
Australia, but I haven't ordered one yet because I don't know what else
I need and how to hook it up without frying anything when I do.

Is there a tutorial or cookbook out there on the web? I haven't found
one yet. I'd be grateful if anybody here in the group could help get me
started.

There are some tutorials out there. The best way to get started would
be to start searching and reading old posts for rec.games.vectrex on
google. You should also get a 6809 assembler. There are a couple of
good free command line ones out there. I use one called AS09.exe,
google that and you should find a copy. Then download an emulator to
test with. DVE is the best but will not run on Win2000 or XP. I
usually use MESS because it has a debugger. VecX is another emulator.

Finally, you will need to get your code to the vectrex. The best way is
to use Richard's vecRam or vecFlash (These allow you to load a game
without needed a Eprom Burner and work very well, I think he is not
producing them right now due to the cartridge case shortage, but that
should clear up soon). If you truly want to make your own carts get a
burner that will burn 27256 Eproms, and get your parts from Mark Shaker
at vectrexcarts.com.

Hopefully, that will get you started. Now if I could just ever finish
one of the games I have started!

Hi,

This is the EPROM simulator I have:
http://www.crownhill.co.uk/product.php?prod=691
I use it mostly for Atari 2600 development but it works great on the Vectrex
too. It only takes about 4 seconds to download a binary.

You'll also need a socketed PCB from www.vectrexcarts.com to hook it up to
the Vectrex. (Get one with the extra serial EEPROM installed if you want to
be able to save high scores etc. Driver code on my website:
www.herbs64.com.)

Or just get a VecFlash from www.vectrex.biz. Has the extra convinience of
being non-volatile and stores up to 15 binaries.

Head on over to www.playvectrex.com for tech documents. In the "Shoptalk"
section you'll find the Service Manual which has a schematic. In "Design
it" you'll find the Vectrex the EXEC ROM Rev. C document (full source of the
BIOS ROM) and the two official Vectrex Programmer Manuals. Some other
useful stuff there too. One thing to remember is that some tutorials/source
code use different naming conventions for the BIOS routines/variables to the
official docs (becuase they were written before the official ones were
available).

The best free assembler is AS09:

I'm in a similar situation, I have a burner but very wary of getting
started, so the EPROM simulator sounds perfect. Just didn't know where
to get one. A few clicks and now one's in the post! :)  Cheers Alex!

Now for a dumb question- I have some 2732 EPROMs and a burner do I need
to UV lamp too or does the burner erase as it writes? Some of this old
school science is a bit hard to figure out! I definately agree an
idiots guide to hardware would be handy.

If anyone else is interested in sourcing one (hardest thing seems to be
knowing what works with what) I bought a Dual Power Willem EPROM
Programmer brand new on ebay. It was $42 from cx829 in Hong Kong. All
seemed very professional, I'm sure he has more. Unless anyone knows of
anything better? I'm in no position (yet) to review it.

MESS has a debugger!?!?!? I didn't know that! Jeez that's gonna save me
some pain. Thanks for the tip. I've been using vecx 95% of the time.

Good to see you old hands are willing to help us new folks get onto the
homebrew train. Cheers!

Yes, MESS has a debugger, but you have to recompile MESS with the debug
option on to get it to work. I think I had to use the MAME docs to get
it compiled, but it wasn't that complicated. The debugger isn't perfect
either, it gets confused when displaying some of the op codes, but just
to have a good view of the memory is a huge help.

DVE had a better debugger in my opinion, but I just couldn't justify
keeping a win98 machine around.

Finally, the most painful part of using the emulators to program is they
don't have the flicker or drift of the real vectrex, so when you have
something working great on the emulator and download it to the vec it
can look quite a bit different.

Yes, you need a UV eraser. The eraser will set all bits in the EPROM to 1.
The programmer can only flip selected bits from 1 to 0. Here's the one I
have:
http://www.crownhill.co.uk/product.php?prod=49

I'm not sure if you're aware of this but 2732s are 32Kbit = 4Kbyte. Mark
Shaker's cart PCBs only take 32Kbyte (27256 or 27C256) or 64Kbyte (27512 or
27C512) EPROMS.

If you can find them, 27F256 and 27F512 are flash chips in EPROM pinout.
Those are erased and written by the programmer. (Make sure your programmer
supports them.)

That's a good price for an EPROM programmer - not sure how good they are
though. Again, here's the one I have:
http://www.crownhill.co.uk/product.php?prod=43
I'm very happy with it!

You can't drop these straight into one of Mark's PCB's.

Pin 1 needs connecting to pin 27, and WE needs to be tied to VCC

Oops, I listed the wrong part numbers. I meant 27SF256, 27SF512.

Ta guys. Mark sent me some 27256 's. He did mention they wouldn't fit
in the intellivision carts he's been using recently instead of SK'd
repro's though. (with his PCBs of course) So I was gonna use them in
their naked glory. Cor will you look at that, another thread seamlessly
referencing SK's cases. :) 

Seriously though, thanks for the tips. Picking up assembler is
(seeming) childs play compared to making sense of the electronics
stuff.

You might want to check out Portal-9 as well. It quite a nice IDE with
support for MESS as well.

I played around a bit with an older version which was a little buggy. But I
just saw there's a newer version available here (which I didn't check out
yet)

http://www.coco3.com/ind_6809dev.htm

Maybe some of the others can also look into this?

Good luck!

O, and if you already didn't, visit

http://www.playvectrex.com/designit_f.htm

There's some links to must read tutorials to get you started and also
info on how to get a free printed copy of the mc6809 programming manual.

Portal9 is really nice, however it doesn't support my complier of
choice; AS09. I've had some interaction with the author Roger Taylor to
try and help with this, but sadly not found the time to progress yet.
Roger is very keen to add AS09 support and I'm sure would appreciate
some advice. (contactable through coco, or I'm happy to forward..) The
problem is that Portal9 can't invoke AS09 properly. Quote: "The problem
is that the as09.exe file appears to be not running as a Win32
process?" I've not kept up with modern windows process spawning myself,
anyone any ideas what the problem might be? (Maybe I'll take another
look at it tonight...)

What is wrong with ccasm? Seems to be compiling most things I throw at it?
