Re: RISC OS 2 - !System and software

Have you looked at the ro2extra.arc file from /acornftp//riscos/releases ? It looks like it contains Clib 3.50, at least. Brilliant, thanks! That has them: Shared C Lib 3.75 (!System.Modules.CLib) MessageTrans 0.06 (!System.Modules.msgtrans) ColourTrans 0.52 (!System.Modules.Colours) FPEmulator 3.2...

Re: Acquired an A3010 today - help needed

Hi Kazzie, Yes, I've done all these things, with the same result. I can just about make out that whenever I type a command at the Supervisor prompt, whether it be desktop, help or modules, I get a 'file not found' error. Perhaps I should try reseating the ROMs?

Does anyone know of any good sources of RISC OS 2 software? Is there such an archive somewhere? In particular I'm interested in the RISC OS 2 !System with later versions of the system modules than were on the RO2 application discs, eg. Shared C Library v3.75, MessageTrans, etc. ...but not so late th...

I'd expect, after a good vinegar clean, that the computer will run fine once reassembled. To my eyes, the biggest problem could be the keyboard connector, just be really careful when cleaning this, that you don't break any pins. If you do, you'll need a replacement connector, which are available, ju...

I also have an old 'prototype' 1mb A5000 in the loft, but suspect your design requires 2mb on-board...or does it replace the on-board RAM completely?

Re: Possible HD problem on A7000+

Depends on the size of your HD. In the good old times of HDs with less than 1 GiB I often used FCFS in compression mode to do a sector backup of my various drives and burned the image as the only file with CDBurn. This is much much faster than a file-by-file copying or archiving. https://www.craig-...

Re: Possible HD problem on A7000+

As above - I suspect your configuration settings in CMOS RAM have been corrupted. This can happen if you run an old (Arthur or RISC OS 2 era) game without using the 'Boot floppy' option in ADFFS.

Switching on with Delete held down, will reset CMOS RAM to default and should bring the desktop back.

Pins 2-17 of the mini-podule socket are identical pin-for-pin with an Econet module, so no extra wiring. (Obviously the select signal on the mini-podule connector is for podule address space).

You need to change one jumper to use the alternative keyboard, you can't use both at once.
