Ah, the small one is line driver to deal with a long-ish cable then.

Sorry, the keyboard dump is bad. The code looks OK from 0x0000 to 0x006b, but the rest of it is just 0x90 repeated, so most of the program is outright missing. Could you try redumping it?

My programmer only has a setting for the 8749 ... am I correct in assuming that the 8049 can be read in that setting (the 8049 is ROM instead of EPROM)?

The emulated Omni 4 boots the disk image, but the logic analyzer software obviously complains about the missing i/o board.



This was added yesterday but the only files I can find that were provided were .hex files.

I'm looking for the proper images that match the hashes provided with your submission, please.

omni4: Unable to find matching ROM omni4.u9 (579665a6)

Thanks

This has been a while in the making, sorry - I've included the wrong files. I think I had to run the hex files through a hex=>bin converter, no further work was done on them

Here's a link - I'll post them on the FTP tonight as well.

Well, I wouldn't count on it. I don't know what the protocol the MCS-48 family use for reading back the program is, but for Motorola 6805 family, it's completely different for ROM and EPROM parts.

Vas, could you please check that dump - my programmer offers the 8048, maybe the program is small enough to fit into the 1st 1K

m5l8049 as i8048

Well, I think we'll have to postpone the Kaypro keyboard until I get a programmer that can read MCS-48 consistently. Prompted by the failure of reading the Kaypro keyboard controller, I re-read the Alphatronic P3's as well, multiple times. Different results every time ... I can get a consistent result for Eproms, but it seems not for the MCUs ... drat!

Just be careful when reading 8048 parts: the voltage for reading 8048 vs 8048AHP vs 8049 parts is different, and using the 8048 voltage (21v on /EA) can damage the later parts (which want 12v on /EA)

This looks like it might be the second half of the program with the first half missing.
