Re: Unable *SAVE *LOAD ASM to 0D00 in BeebEm

If you want a low memory fixed address area, use say &0900 - provided you code isn’t huge, this will be fine.

Re: Wires? Pah.....

Ah, ok thanks Dave - I confess that I saw the square surface-mount device and glazed over assuming it was a CPLD VIA emulator or something - my bad :) Regarding the 2MHz clocking with no access slow-down, the 'special' UPURS v5.9 was exactly for that purpose (and at the new base address) because Sim...

Re: Wires? Pah.....

That looks perfect Dave - I see the base address is as per Simon's implementation but with Steve's device not being based on a genuine 6522, I presume it will behave the same on the outside-facing interface down to a microsecond level...? :-k I only ask because as you know, my bit-banged RS232 is as...

How much are the PH-02-02's Dave? I think I'll probs take a couple to future-proof my HD Elks and Beebs.... :)

BTW - Standard genuine 1772 chips will all work with my HD mod (not the 1770 =; ) but if I ever go back to looking at ADFS, I think the 02-02 might just have the required edge.)

This is a Beebug disc and its the first auto-menu item again. This one does run on a Model-B but note that the requested 'Day' is the numeric date, not the day name as I first tried.

Re: DFS/Cumana Disc fault 18 - help!

Yes - if you have the drive itself set to 40, then each head step should move 1/40th of the total available travel. *FORM40 should issue 40 steps (I'd count them to be sure :wink:) and if so, the head should perform the full travel. If it only moves half way, then as you say, the drive itself is sti...

Re: Eclipse predictor, maybe from BeeBug

Here you go Ed, a TMU cover disc. Its the first program in the auto-boot menu but on a basic Model B, it bombs out with "Bad mode at line 70" (I presume short of memory) so I tried it on a Master 128 and it ran fine.

But for all four heads to have failed (or be gunked up with dirt), that's fairly long odds.
