Re: Cumana CAA740 scsi hdd podule for A3000: dead 2.5" hdd

Seems to be one of these; https://www.ebay.ca/itm/254154458131?ul_noapp=true Not sure, but there looks to be another Internal SCSI header on the Podule itself, so it may be possible to attach a more 'standard' SCSI drive. Can you remove the drive and/or cable so we can see more of the podule? Edited...

Re: Cumana CAA740 scsi hdd podule for A3000: dead 2.5" hdd

Bit confused, SCSI and IDE are two different standards and aren't interchangeable.
Are you sure it's not a 50 pin scsi drive you have?

Re: Design a logo for ABug!

I have done some experimenting and have attached three files here: 1) The original logo as a PNG. 2) The logo with a transparent background instead of black. As I thought, this doesn't look great. 3) As above, but with a black outline around the edges. This is better but still not ideal. 4) A rearr...

Re: A310 mono output works - no RGB

As a matter of interest, have you reset the CMOS?
It could be a corrupt CMOS setting that's sending out something your monitor doesn't understand.

It's a RISC PC/A7000 only device, it would need a whole different connector (card edge) to work without a backplane.
Of course it is! Must have killed too many grey cells over the weeked. :lol:

Re: A potential run of BeebSCSI 7.7 (the newest)

I did at the top. Their use is very limited at the moment, they let the beebscsi operate as the vfs portion of an lvrom player on the master's internal connector (and issue the laser disc control codes from its serial output). It's read only and hence probably more of a curiousity at the moment tha...

Another option would be to see if I can allow the host machine to switch banks, so it can access the whole 16MB (maybe with a fixed 1-2MB and a paging area above that). I don’t think the fast serial port option I was talking about will work, but paging might. If you've got 16Mb to play with, that p...
