here is the bar= e board list.  the backplane and port prototyping board are only in TI= N.  You would only need one bus monitor LED jig since it is not a cons= umable.

this would all fit in a small or me= dium usps flat rate box, so $10 for shipping.

Hi Fred,

 

To the e= xtent possible, I have given up on surface mount. Just too small for my lik= ing. I already have to use head magnifiers most of the time.

 

You have a= nice collection of boards, perhaps you will want to extend the SBC-85 bus = to include some of your own boards if you think of something that is missin= g.  People are always asking for some sort of video output or disk con= troller, but neither of those appeal to me much.

 

PALs and GALs are just= more trouble than they are worth for this scale of board and the user base= .  Like you said, it is one more hurdle to get over and there is not a= n obscene amount of glue logic required. Yes, it would be easy to compress = more in the same size or offer more features. I just didn=E2=80=99t want to= go there.

 

=

I have one of those HP 8085 trainers, not a bad bit of kit a= ctually.  I prefer the SDK-85 but even there the monitor could have be= en improved. I run a better monitor on mine and it makes it a nice little t= ool.

 

As for the website, I never really intended on this to take off an= d Wordpress was an easy way to start. I understand where you are coming fro= m. I keep thinking I will have the time to move over to GitHub or something= similar, but that hasn=E2=80=99t happened yet.  I will see if I can a= t least clean it up a bit.

 

I will get these together and price out, opt= ion for one gold set if I have them. 

 

Let me know of any problems = you find in the manuals, BOMs, or software.

 

Regards

Hi!

 

See attached, f= orgot.. just some of the smaller ones I did over the years.  I like do= ing PTH, as most people

can (still) = do that.  SMT makes for smaller boards and more functionality, but, as= you know, your customers

will bitch= :)

STD is not my thing. I know about it, of co= urse, but never did anything with it.  For the 8bit stuff, I dont

think one needs anything more than "just= " the (demuxed) CPU bus- even though that somewhat locks

you into that (family of) the CPU.  I do like ho= w your boards use buffers; something (else) I missed in

the Glitch stuff.

 

Now, here's a thought.&nb= sp; How come only Sergey's boards use a programmable device (GAL, in this

case) for combining a load of the glu= e logic?  OK, yes, that makes you dependent on another "hard"

(for some) chip, but it makes things cleaner= , and smaller.  I think the address decoding stuff (for the<= /p>

RAM and ROM selects, but also for a "block" of= I/O selects), and even a little bank switcher, would

be a great addition?

I have several not-so-great experiences wi= th Tindie, including very recently.  So, yes, I'd prefer to<= /p>

do a direct buy from you.  You can keep t= he discount.

Yeah, I= saw the write-up.  Heheh.  Last night I remembered that I *have*= done something with the

8085 in the= past- when I was in school (uni, 1985) they dropped that HP suitcase on my= desk, with

a lab manual.  Ugh.=   I later ripped out the 8085 board (and dumped it) as I wanted the su= itcase :P

 

> Let me know what systems you are interested in s= tarting and what questions you have.

Oh, I have various 8085 boards now, just to play around with, and to look = at how they are all

different in th= eir design.  I liked Glitch's stacking mode, but dont like his board d= esigns and the

no-buffering.  I= liked your cassette board (first thing I saw about your projects, haha!) a= nd then I

noticed the buffering, the= VDU board, etc.  Sergey's stuff (I have a lot of his stuff) is nice i= n yet

other ways.

 

&= gt; I presume you have found the users manuals and example source code on t= he project site.

Yeah.  I have = to be honest - I seriously dislike your site.  Or, no- I dislike Wordp= ress, and I do not

like how that f= orces certain things.  These days, developers use a simple site that l= inks directly

to github repos where = the "stuff" is at.  Easy to clone/fork and then keep updated, etc.&nbs= p;

 

> Let me know where it ca= n be improved.

I did not like having to= go through each "product" page, then dip into the "downloadables" for

it, click DOWNLOAD within each, and so on.&= nbsp; That is a typical Wordpress flow.  I would prefer

these files to be either directly clickable, or, the = more modern approach, have them in a repo,

with one repo per product.  Also allows the customer to keep an ey= e on updates and so on.

 

> Also I tend to leave placeholders on the w= ebsite and then forget to go back and finish. 

I did see several mentions of products in the writeups (the sp= io_i2c comes to mind) that exist,

<= span style=3D"font-size:10.0pt;font-family:sans-serif;color:#26282A;">or di= d, but nothing else is there.  I also see products (bus proto and io p= roto) that apparently

have falled off= .  That could be cleaned up, either way.

 

Ordering.  I have a = habit of ordering a complete set of things, so:

 

- backplane

<= /div>

- cpu

- bus mo= nitor

- bus proto

=

- mem exp

- cassette

- spio

- spio_i2c

- io proto

=

 

as far as th= ey are available. Not sure if the 'proto' ones are, for example.  Idea= lly, I would

like full-parts kits (mos= t of my stuff is still packed up because I could not use it for 2+ years)

but not sure if you have those.  I = would like 2 boards of each (one to build, one to keep as-is)

and, if you can give me a good deal, gold-plated wou= ld be preferred for at least one set of

boards.

 

Please advise.

 

Regards,

 

Fred
