Re: Building a BBC

There's no BASIC in there. That won't stop a BBC B working, but it will limit what you can do in terms of testing blind if the video isn't working (like typing in a SOUND command to make a noise, or even just pressing COPY). IC6 is the early VC2023 ULA so the bodge on the solder side of the board is...

Re: Master ADFS problems

Is it possible you have a single-sided disc drive? An 80-track Master 128 Welcome disc has all the data on the "second" side of the disc which can't be read by a single sided drive. The 40-track version uses the "first" side. It's the same disc, but there is a utility on the disc...

Oh right. I don't think I knew it was missing. I have several LVL DOS related items, all in storage, including a non-working BBC B with LVL DOS board, which looks to have quite a few chips missing: Thanks for the photos, much better quality than those at http://chrisacorns.computinghistory.org.uk/8...

No, that object didn't exist previously but it creates the directory during the run as you say. Then there is a 33 byte file inside with the name of the first sprite.

Re: Books that need rebinding

A perfect bind is a type of glue binding. I think if you are connected up to one of those industrial printers the size of ERNIE you get an option for "perfect bind" in the print finishing settings.

Re: Dead MDFS Resurrection

I'm not sure I was right about the hardware test sequence after all. If I have a SCSI and FDC error then I get 6 flashes for SCSI. So it appears to check the SCSI bus before the floppy disc circuitry. IC32 is socketed in the dead MDFS and it's an ancient 7404, date coded 1975. I reckon that could we...

I think it must be reading something, because it remembers my default location and saves in the right place, it's just the file type which is wrong.

Re: Dead MDFS Resurrection

No it doesn't! Swine machine checks its hardware in reverse order of number of flashes! So, with the RTC chip out, battery out, you would expect to get 1 flash for CMOS RAM error. Nup. With the FDC chip out you get 4 flashes. With something unpowered plugged into the SCSI bus you get 6 flashes. So I...

Re: Dead MDFS Resurrection

Last night I swapped the FDC and IC35 in view of the 4 flashes. Usual results - known good parts didn't fix the dead MDFS, suspect parts didn't break the good MDFS. IC32 also looks to be part of the same circuitry, with it removed I get the 4 flashes, but I can't swap with the good MDFS as it's sold...

Re: Dead MDFS Resurrection

No, it actually said free shipping on the product line I selected, and there is a banner across the top of their site now saying free shipping even on orders under 5 dollars. So it should be free.

I don't mind paying, but I won't pay if I've been led to believe I don't have to pay.

I am trying to order more RAM from UT Source, everything on their website says free shipping but when you try to order it adds a shipping charge. I don't like it when they try to sneak on extra charges at the end. A lot of websites do that.

That's WD1793 fault, the floppy disc controller. I don't recall ever having that before. It can't be cleared, so I had to turn it off but it's just gone back to all lights on. I'll leave it for a bit and if the error recurs I'll swap controllers with MDFS2300. I don't want to do that unless it's a r...

Disaster...after 3 days switched off whilst I was playing with the other RISC PC and the Cumana podule it was back to its old ways.

Anyway, it turned out the batteries had gone flat. New batteries in and it's fine.

So there must still be something wrong with the charging circuit I made.
