Cartridge Read: Mystery Eprom now dumped
https://www.ebay.com/itm/Eprom-Card-for ... true&rt=nc
Hi,
I purchased this from Ebay, would anyone be able to help me read the Eprom?
I tried the cartridge and nothing comes up on boot but I am curious if there is something on the chip to preserve.
Thanks.
Ian

Re: Cartridge read
Congrats, I was tempted to go for this but resisted. I think it's worth trying to recover the contents, I believe it's a 40 column utility which would be interesting to see.
It looks like the PCB is wired to use BLK5 but as the EPROM is a 4K device it might be mapped into $A000-AFFF or $B000-BFFF. Mike has a neat trick using SYS that can save a memory region, I'll see if I can find it.

Re: Cartridge read
Did you have any luck?
Re: Cartridge read
I came across a barrier I had set myself - I had lent my video cable to someone and no longer have a modulator. I have this back now so will try at the weekend.
If you pm me your email address I will send you the resulting file.

Re: Cartridge read
Incase this does not already work in VICE anyway, i'd like to see this ROM dump as well...
I'm just a Software Guy who has no Idea how the Hardware works. Don't listen to me.
Re: Cartridge read
This eprom cartridge has now been dumped thanks to Simon's help and Mike's code.
I can now start it in Vice - sort of.
PM an email if you want a copy.

Re: Cartridge read
Simon has got this cartridge running but we don't know what it is yet.
SYS40960 displays a table on the screen
DISPLAY :000
COLOUR :000
DIS-ROW :000
DIS-COL :000
LEFT-MG :012
TOP-MRG :038
BASIC :016
RAMTOP :000
Pressing enter reduces ram to 3071 bytes free.
Does anyone recognise this utility cartridge?
Does anyone have a manual?
I think it may well be the Solidisk 40 column utility as the board is STL (Solidisk Technology Limited) and the advert above lists a 40 Column rom and a Programmers Toolkit rom. This eprom is labelled 40c.
Interestingly, Solidisk are still going: http://solidisk.com/
