I'll have a go, not sure what timezone you're in?

Does anyone know where this BASIC4 ROM came from? It has an IEEE command but it's expecting registers in IO3/ (and IO0/??) so it's not designed to work with the VIC-1112 (which only uses IO2/).
The lockup in VICE is here
Code: Select all
la12c lda $9c02
and #$20
beq la12c
I don't know of any addon card this could be for.

I remember recovering Basic V4 back in 2006. It works well on a 1541 drive.
I also remember it occupies only the lower half of BLK5. AFAIK, the firmware for the VIC-1112 is supposed to use the upper half of BLK5.

I don't agree that these two ROMs were intended to work together. They both intercept some of the same vectors and BASIC4 has code (such as I showed above) that implies it expects hardware with different registers to the VIC-1112.

@srowe
I have mostly used Basic V4 for the VIC-20 by itself, never in conjunction with anything other than VICMON and/or Programmer's Aid and the ones I had before 2006 only reside in BLK3.
I am very surprised Basic V4 has routines that accesses registers in IO3.

Does anyone know when this is likely to ship? I haven't seen an update in ages.

Dragos has just posted an update
https://www.kickstarter.com/projects/12 ... ts/1530322
I've been working on trying to get a ROM image that also adds the disk commands of PET BASIC4. Made some progress this weekend but not quite there yet.

What's the news here ?
The boards were supposedly sent for fab back in march... nothing since.

Good quality gold plated boards, very nice looking packaging material.
Nice product!

Great looking product and packaging....
but your photos suggest that you still haven't addressed the error I pointed out
here:
where your instructions to SYS45056 are wrong (should be SYS45065) - although one screenshot does show the use of SYS45056+9 to invoke the card.

Dragos asked me to fix this error on the instruction sheet a few months ago. The photo on the Flickr page is old and does not reflect the corrected version.

I will now give it 10/10 - Excellent!!
