Hi
Does anyone have a manual for the RM65-1000 or RM65-1000E 6502 SBC? This it the industrial SBC they made. I'm looking for the jumper configurations.
Thanks
Dwight

Hi Dwight,

When I search for the word "jumper" in this .pdf I come up with 107 matches. Could any of those matches have the slightest chance of being applicable to your situation at hand?

Many of the other boards have list of jumpers, there is just nothing for the CPU card in the data books. They'd have had a separate manual that would come with the board. I've not found anything on the web.
Its got some specialized software on the EPROMs that came with the chassis. It was some type of ICE setup but missing the dongle module, that part is of no use. The processor board uses two of the 68766 EPROMs and I think I can patch the software to run the Forth that is in the code instead of booting to the original. It expected to have a disk to do the main functions but still had some low level test code for the ICE stuff. When I get some time, I'll see if I can bring it up to the Forth interpreter. It just needs some minor patches the boot to the Forth interpreter.
I do have the floppy controller but no drive with it yet.

IIRC these are 24pin 8K (!) EPROMs. Only one pin (/OE) to control programming/verification. There are no much programming tools that support these types (68764 was similar me think).

Good luck!

My programmer list it so I'm in good shape there. I have a couple extra EPROMs so I don't have to trash the originals.
The Forth they use is pretty much fig-Forth with a few patches for ROM based for user variables.
The board is really dense so tracing what the different jumpers do will be a real pain. Although, 6502, it has banking capabilities. I have 64K of main memory but there are some static memory boards used on a separate bus for the ICE board. I'd like to move them to the main memory and add battery back. For that I have to figure what jumpers are related to banking selects.
Dwight

Have you tried asking on other forums? Just an idea. Maybe Ed or someone can suggest which ones might be worth a try.

I'm not sure which forum would be best. I've posted in the vcf forum in the past with no results. I thought that someone here might have used one of these in the past.

Mmm, this should indeed be a good place. There's retrobrewcomputers forum, and the classiccmp mail list, which are worth a try (nothing to lose!) Maybe an OT post on cbm-hackers list.

If you could post a good picture of the board or boards, that might help in tracing the purpose of the jumpers, and with a good photo one can also post on social media: you might need to cast a wide net to find someone who knows someone. I know there's a facebook group for Acorn's BBC Micro, and there are a few communities for vintage and retro computing on gplus.

(posted the query on Stardot, an Acorn forum but with quite a few technical members who might have unusual 6502 kit.)

Yes, a good one, and rather active: https://www.retrobrewcomputers.org/foru ... &frm_id=1&

What's an additional VIA among friends, anyhow?

Finally some results. On vcf forum, a fellow got two AIM65 and an extension buss with several eurocard boards and a bunch of documents. Even though he did not get a RM65 -1000(E) processor board in the collection, in the pile of manuals was a manual for the RM65-1000(E) board, with description of the jumpers ( scattered through text ).
I've copied out my EPROMs and have looked at the init that is there. There are parts of the init that no longer apply to the boards I have so I've modified the init to boot to a serial terminal. I hope to get back to fiddling with that once I get the current project completed. I'm bringing some old I4004 code back to life with some real hardware. For those that might be interested, it is code for a maneuver board. For those that don't know what that is, it is related to ships and avoiding running into them ( or targeting them ).

IMHO it's good practice to document jumpers, switches and headers, at least briefly, on the PCB's silkscreen. Not that it helps you in this case, but future projects may benefit from this advice.

The RM65-1000 is so packed with parts, there is no room for such nice things. Think of an AIM65 crammed onto a eurocard board. ( less a few eprom sockets and a little less RAM and only one 6522 ). It needs to run the bus, interrupts and bank selection as well.
Even so, I'm not sure there would be enough information to know what each jumper does. At least most Ex numbers are visible.
