CST Procyon IEEE system ROM

Post by leenew » Mon May 13, 2013 3:25 pm

Hi,
I am selling some stuff on eBay as the missus says she doesn't want to get a pair of knickers out, only to find a floppy disc stuck to them, or to put the iron away, only to find the space taken up by 4 boxed 'rare' joysticks.

*tsssk* She's a strange one :roll:

Anyhoo, one item I have for sale is the CST PROCYON IEEE interace.
I can't for the life of me remember where the system ROM is??
Obviously, I have checked behind the cornflakes and on top of the wardrobe.
Can anyone help?? :D

If the hardware "looks" like an Acorn IEEE interface, then there's these IEEEFS ROMs.

Thanks Jonathan.
I believe the CST version was the only one to incorporate the CBM filing system to connect PET drives etc?? Still would like to find the CST one if possible.

According to the July 1984 Acorn User review, the CST Procyon was perhaps the most capable IEEE-488 / GPIB interfacing option, what a pity the ROM/S appear lost in time, or more likely numerous landfill sites..........

I also have a Procyon which I purchased in the hope that the ROM would eventually appear. However, I am not holding my breath.......

Looks like someone on the acorn facebook page might have a copy of the ROM. I'll post it here if I get an image of it.

Hmm, whats that second from the left?!

His beeb also has an aries B32 sideways ram board in it and I presume a 5.25" floppy drive. Whats an easy way to get the rom imaged onto floppy? I really only use my master now so woyld just use '*SRSAVE' but thats not available on the beeb so some help is needed.

Can someone suppy me with detailed instruction on how to get the rom image onto floppy using his kit:
5.25" floppy, DFS 0.9 and an aries B32 ram card.
Thanks in advance!

I'm the chap with the CST Procyon ROM in question. I'm going to have a look at it tonight and see what I can do.

If it saves ok onto 5.25" floppy I may be able to get it off onto a memory stick via my main Beeb, which is equipped with a RetroClinic Datacentre.

Keep your fingers crossed, we may be about to save the world... :shock: :lol: 8)

Incidental to the ROM issue, does anyone have a spare 1Mhz bus cable and a set of BBC Model B case screws they'd be willing to part with, or can point me in the direction of a supplier, please?

Ok, I saved the rom using the program given earlier, onto a 5.25" floppy disk and swapped the drive over to my RetroClinic Datacentre equipped Beeb and thence onto a memory stick...

However, I can't upload the file here as the forum reports 'The extension is not allowed'. There is no extension, the filename is simply IEEEROM - any ideas?

Either, compress the file using zip. The forum will let you upload a zip file.
Or, just rename it with a .zip extension. Again, forum will let you upload such a file.

Just remember to tell us which option you used!

Judging by its size, that was an ssd? - but the disc seems to be gobbledygook? Just looked at it in dfs explorer/hex editor, there's loads of "stuff" there, but no directory? The stuff doesn't look like a ROM image. Could you see the image on the datacentre?

(sorry, loads of ? marks!)

Dumping it shows the first 512 bytes are zeros, with &320 at the disk size location, so it's a 200K DFS image with no files in the catalog and garbage in the data area.

When you saved the ROM could you *DUMP the file and did it look like a ROM image? Eg:

Code: Select all

*DUMP ROM
0000 00 00 00 4C xx 80 xx xx ........
0008 xx xx xx xx xx xx xx xx rom title
etc.
You say you have a DataCentre. You could save it directly to the USB stick like this:

Code: Select all

Y%=12
FOR A%=0 TO &3FFF:!&F6=A%+&8000:A%?&3000=USR&FFB9:NEXT
*RAM
*DRIVE 5
*SAVE IEEEROM 3000+4000

I would assume that bit must have worked if it was saved to floppy, and then read successfully onto the other Beeb that had the datacentre?

So would guess it was the second Beeb transfer that went a bit wonky. At a guess.

Hmm, regardless of whether the program worked correctly or not there should at least be a file called IEEEROM which is 16k in length on the disk image.

The rom looked ok, as far as I can tell, after a *DUMP. but I'm no expert.

Can anyone get into a .ssd file and extract the rom file to check it please?

If so, here it is zipped and attached. I've opened this under BeebEm and the ssd *CAT's ok, I can't say any more than that.

Otherwise I will have to see if I can swap the rom into the Datacentre equipped Beeb tomorrow and see if I can save it direct to USB as suggested by jgharston.
