It would be interesting to learn more about this board. I don’t see any markings on it?? no manufacturer? Odd… let us know if you get it!

What the ???!!!
I guess I moved out of northern VA a few years too early… This guy in Hamilton seems to have quite a trove of Heath stuff…
To so be clear this is a pristine and very nice looking NOGDS HA-8-3 board and documentation (but I don’t see the floppy disk with software?) Those are unusual but they do come up on eBay from time to time, typically installed in an H8. See clip from catalog 853 below. our fellow SEBHCer David Troendle was part of the NOGDS team that developed this board and the software. (NOGDS = New Orleans General Data Services – catchy name 😊 ).
The rest of the lot is just a bunch of old Jim-Pak stuff and some spare ICs. Am I missing something? Is that PCB something special?
$1,300 ?? seriously?
I missed this in my eBay search. What category was it posted in?
FYI we have cloned this board and we have the software and doc’s
https://koyado.com/heathkit/New-H8-Website/ha-8-3.html
I’ve had some fun writing new software for it and will post more about that … one of these days…
Recently Les discovered the long lost Graph-Pak II software and doc’s for this, plus we have some HUG games and one actually written by Les himself “back in the day”! but all-in-all not much software was ever published in the Heath space for this board… the TI9918 video chip and AY-3-8910 audio chip used on this board were used in a wide variety of computers and game consoles at the time.

Well it shows the importance of presentation. The other recent one went for almost $1,000 more, and wasn’t that different in spec’s, but has been cleaned and serviced and was advertised as in working condition, vs. “for parts or repair”.
If anyone here was the buyer on either of these we’d love to hear about your plans!

So I guess I can sleep tonight; this sold. I really didn’t think it would last the night (though with a “make offer” listing do we actually know what the buyer paid?)
I seriously considered at least making an offer on this. The market has spoken, and presumably this sold for somewhere near the asking price. Still it would have been an exciting auction to watch if it hadn’t had a “buy now”. Given what we’ve seen some things go for lately who knows what this would have fetched in open bidding!? Anyone want to fess up to being the buyer?
I don’t think the seller even mentioned the two Mullen extender board kits? And all four of the 4K RAM boards had the H-8-3 4K RAM expansion. It really is a remarkable collection…
But what would I have done with it? sell the pieces I guess. I couldn’t bear to actually build these, though some YouTubers with enough eyeballs could perhaps monetize their “build” video?
Presumably these will show up as individual listings soon so watch your eBay search results...!

Really odd that there are no commercial markings on that RAM board. I tried looking through a few old Sextants to see if I could spot an ad but no luck.
Congratulations on your new H8 Willis. Hope you can post more here about what you learn about the system and any restoration or updates that you do!

Hello Willis,
Any opportunities to ship your board to Scott, so that we can duplicate such board at a smaller scale? I can share with you one of my memory boards fully assembled (512KB) or I can send you a Z80 V3 board fully operational with 64KB of RAM to keep you busy with such system until Scott is done with his new re-design… 😊
Thanks for all your support,
Norberto

Well that was a day "wasted" looking for an ad for this board.
You would think it had to be advertised somewhere for three
of them to show up on Ebay.

I did look in articles and classifieds.
You don't see much for the H8 after
Heath ran out of them. (FCC)
A couple companies used the

That was a good price on the memory board.
One of the S-100 boards was "Jaws"
maybe some ideas can be found in this design.

Interesting to look back at those posts.. from as early as 19 years ago!!
Here’s Jack’s welcome post
https://sebhcmaillist.heathkit.garlanger.com/sebhc/2004-March/000001.html
much has changed since then, but much hasn’t. sadly we’ve lost some members, and others have moved on to other things. When Ron West “retired” from the hobby he sold me his Z80-based H8/H19/H17 setup.
I see a few posts from me back in ’07 lamenting that my H17 disks were 20 years old. Now make that more like 40!
Glad you kept these Mark. Thanks

I'm trying to imagine how someone put 17 holes around a 5-1/4 diskette hub... without cutting the whole thing out... seems like the sector holes would be wider than the space between!
I'd heard of 16-sector 8" diskettes... never knew there were 5-1/4 ones...

SSDD would work just fine on the H17, but the 16-sector will not.
The SSDD only indicates how the diskettes were verified. All
DD-tested diskettes will work just fine in SD. The standard H17
was single-sided originally. We used to use SS diskettes in DS
drives/applications, but one was taking a risk that the second
side was inferior. Really depends on when the diskettes were
manufactured as to the chances of getting a usable second side.
Hard to say whether these diskettes were rejects from DS testing,
or just not tested DS.

Northstar used 10 sector. Vector Graphics used 16 sector.

Who used 16-Hard Sector disks? Northstar? I suppose if you were ambitious you could modify the H17 ROM timings to use these… (like seriously ambitious…) I presume sectors were 128 bytes?
