Please see below for 2025 updates to BeebMaster

1st March 2025	Some picture sets on the general topic of Programming to start this March update:
		Here's an update to my ADFS trick disc.		This is a brief look at ROM service calls from August 2022.
		This set shows some experimentation I made on using the Break vector in August 2022.		This set from August 2022 looks at some of the differences in the instruction set in the 6502 processor used in the BBC Micro and the 65C12 in the Master series.
	And even more on my Ecodisc travails now:
		Here's a look at trying to read the bad sectors on my Ecodisc caused by laser-rot.		My next idea was to try the Ecodisc in the VP415's diagnostic modes.
		This is a look at my CountDir utility with the Domesday discs.		This is my CountDir utility running on the Ecodisc.
	Now for some hard drives:
		This is some investigation I did in August 2022 to see if I could devise a foolproof method of knowing when a Winchester disc is connected to a Beeb.		Here I am trying to work a Kyocera Winchester Disc using my Adaptec rig, which had been one of the candidate drives for fitting to my Archimedes 305, but it didn't take.
		A problem developed at Station 87 in August 2022 with the SCSI interface.		As I've added a new picture set involving Econet Station 87, and the section for my Second Domesday Machine seems to be in good shape, I have begun the process of adding links to my Econet stations in the section on My Econet which I began rebuilding in November 2024.
	A look at some 8-bit peripherals:
		This is my UviPROM EPROM programmer, my earliest programmer, which doesn't get much use nowadays, but in August 2022 I did give it a rare workout.		Now a look at using the UviPROM control software.
		There's a version 2 of the UviPROM control ROM, so I am trying that in the hope that I have more luck with 32K 12V EPROMs.		This is a look at making some little carrier boards to take an EPROM or sideways RAM chip, without having to modify the chip itself.
	We finish with the beginnings of a new section on the 32016 operating system, Panos:
		This set shows making a set of Panos installation discs. In fact, although there are seven discs altogether in the Panos set, I am only making discs for the first two, which will be sufficient to install Panos.		Having successfully made two of the Panos installation discs, it's now time for me to try Panos for the first time. A 32016, or 16032, Second Processor is sadly something missing from my collection, but Pi Tube Direct comes to the rescue with over 20 second processors to choose from.
		The Panos installation discs contain install scripts for various situations so that it can be run without having to load it all from DFS floppy disc every time.		Next, following on from my success, after ironing out some blips, in installing Panos on my RISC PC Level 4 file server, a more authentic 1980s experience, installing on the L3 server.
1st February 2025	February's update begins with more on the Ecodisc:
		I made a new version of my "Count Directory" utility to take into account the space used on LV-ROM discs. Here's the utility before the changes so we can see the difference.		This is the enhanced version which can cope with VFS discs.
		Version 1.2 of my Read/Write CMOS utility from July 2022 is here.		Here's a quick routine I drew up to print out a memory dump.
		This was a bit of fun in July 2022 when I made up an ADFS disc full of Pi digits.		Shortly after making my Disc of Pi, I devised a way of freeing up even more space on an ADFS disc than is usually available.
		Here's a look at the "Bad key" error in BBC BASIC.		This is a very irritating problem with the Level 4 file server.
		This set shows the ACB4000 series of Adaptec ST506 Winchester Disc controllers in use.		This is a look at mode select using the ACB4000 series controllers, from July 2022.
		In July 2022, 3 years after first introducing my HTML Generator, I devised a method to use Inter-Word to write the caption files. Please click on the picture links above to learn more.		In July 2022, I devised a more automated way of taking Beeb screenshots, using a dictation system footpedal.
		A quick set showing how ADFS 2.10 doesn't work with the Master 512.		I had a special viewing of "Daleks' Invasion Earth 2150 A.D." in July 2022 in memory of local lad Bernard Cribbins, who played PC Tom Campbell in the film.
		You can't tell from the pictures, but Wakefield 2023 took place in Bradford.		I attended my second retro-computing event of 2024 in April when I made a further return visit to Camberley.
1st January 2025	Help to see in the new year with a special LaserVision and Domesday feature for this first 2025 update:
		This is a look at "Helping Your Child To Read" with my Domesday Machine in July 2022.
		This is a look at the "maximum" frame number which will be accepted when communicating with the LV-ROM player via SCSI.		Another look at maximum frames now, with the LV-ROM player being operated under serial communications.
		This is a quick recap of the problem of trying to work out how many CAV frames are on a laserdisc which happens to be an LV-ROM Disc.		I worked out a fix for the SCSI communications problem when trying to calculate the maximum disc frame, as used in my LVInfo utility.
	A major new section about the AIV Ecodisc starts today:
		This is a new picture set of my Ecodisc which I took in July 2022 to coincide with its thirty-fifth anniversary.		In July 2022, on the approximate 35th anniversary of the publication of the Ecodisc, I tried it out for the first time. It had been in the wardrobe for over 15 years.
		Now a look at the Ecodisc with my LVInfo utility.		It shouldn't be too difficult to make a logical backup of the Ecodisc - it will all fit on an ADFS floppy disc.
		This is an attempt to see whether the Ecodisc Plan sections will work, even though the Plan files have rotted away.		Here's a look at what happens if we try to run the Ecodisc with the Tube off.
	To finish this new year update, some bits of programming with functions and procedures:
		This is a brief look at a programming technique which allows a Function within a BASIC program to be called by building the name of the function using variables rather than having to hard-code the name of the function each time.		This set is a bit of a warning about being careful to use the right arguments in functions, or unexpected results can ... result.
