Today I received.....

A rather nice out-of-the-blue gift. A Z180 kit with the CPU clocked at 18MHz. 512K ROM WBW, 512K ROM Monitor, 512K of RAM and a sprinkling of useful interface ports (serial, SD, USB etc). The homepage is here:

All I have to do now is think of something to do with it. Modifying my FIF (Fif isn't FigForth) for it is a possibility.

Ah yes Stephen Cousins I have some of his RC2014 boards.

The scope did not reveal much information. Although I saw that during one CS pulse of the 8255 there were two WR pulses. But that occurs also on a standard Atom without Yarrb. Perhaps a scope is not enough and I have to get the help of my logic analyser. I'll post in the Yarrb topic if I have any news about this.

Never enough toys. Always need another ...

OK, not Acorn related...unless you need a mouse caught.

Is it one of these new AI robot mouse catchers?

Is it one of these new AI robot mouse catchers?

Yep, runs on RISC OS...well, if she had the chance to get to my computers - although she'd probably sleep on them!

Truly RISC based or more correctly ZISC (Zero Instruction Set Computing). Can't get then to obey any commands.

I think ours are CISC

Complex as we haven’t worked out how to program them yet apart from mealtimes where they are strangely very compliant to commands

I think I'm probably good now for Commodore 8 bit machines (although having said that there's another C128 arriving next week).

And here it is.

It's a superb shade of yellow and absolutely filthy inside and out (the picture doesn't really do the filth justice). The plastic clips that hold the metal rod of the space bar in place have broken off, but I do have them (and the spacebar itself), so hopefully I should be able to fix it. Apart from that it works nicely, in both C64 and C128 modes. Oddly, it's only the case that's yellow. The keyboard, now cleaned, is reasonably white. This is in contrast to the other C128 which has a white case but yellow keyboard. I'm thinking of making myself one white C128 and one yellow one.

Just arrived in Canada from Blighty!

On Sudnay I finally got my A5000 Alpha back from my friend, repaired, recapped PSU, and upgraded a bit

It has:

8MB Ram
Gotek with Flashfloppy as drive 0
Currently not set up CF as HDD
Quiet fan on PSU which makes for virtually silent operation
MEU (not set up as need to find my spare SCSI card)

Not sure what podules to fling in it other than SCSI for MEU and possibly Color card from R260 as it doesn't get used properly in that machine.



To say I am chuffed is an understatement, need to get it set up properly.

[vanpeebles]

My Alpha was the only machine I wish I'd never let go. Although it went to a good home. The best classic Acorn machine in my opinion. Big CPU grunt and RO3.1.

Ethernet podule? Relive the internet ca. 1996

Forgot about that, and have a spare. Internet would be scary and a bit of a no-no but it would be handy for getting stuff to and from my Arcs...

Econet? Go really retro.

Econet? Go really retro.

Not that brave, plus have econet joy port interface...

[stuslayer]

IDE Interface plus DOM from IanS, a copy of the RISC OS 3 User/Apps Guide from DaveH, a USB floppy drive for the PC from Amazon, and a Benq BL702A, used from eBay for £25. Let the fun commence!

A VecFever cartridge to hopefully release the after Moon Patrol on beeb and Vectrex.

... An Amiga A500+ with a non-working keyboard

Which thankfully only took an hour to diagnose once I found the schematic, then I put it to some proper use:

Basically I fancied building up one of Rob Taylor's A500++ boards for a bit of light relief -- so was delighted to find one in a broken state. I only fixed it to check out the donor parts

[markjw]

a Sinclair ZX80 in original packaging including the outer brown cardboard shipping box - has the original power supply, RF and tape leads, manual and two copies of a A4 sheet titled ZX80 Test Program. Condition of the machine and packaging is very good and looks like it was hardly ever used, though the polystyrene packing is slightly damaged at one end

Also got a BBC Micro Teletext adapter, an early Socket A AMD Athlon/Duron PC and an even older pre-ATX PC from the same person (not had time to strip either PC down to find out what they actually are yet)

A nice, working Tatung Einstein. Its huge. ZX81 for scale...

[KenLowe]

Some new bits for my Atom. Ok, they didn't all arrive today, but this is the first chance I've had to look at them all:

I'm hoping to be able to use my PiTubeDirect CoPro with the Atom Tube interface, but I'll probably need some guidance. I'll follow up on the Atom Tube Interface thread. I think I'll possibly also need to get an AtoMMC interface too if I want to get this all working, but SirMorris is currently out of stock .

A bread-bin C64 :

It's in reasonable cosmetic condition. The upper half of the case is very yellowed though and there are some minor cable burns. Inside, everything appears to be present and correct. So it hasn't been stripped of the SID or other custom components.

Three ICs (including a TTL logic device) are randomly socketed; making me think that it has had some work done at some stage. This view is supported by the fact that two of the plastic lugs have snapped off the upper case.

My attempt to check the voltages on the PSU resulted in some very impressive sparks and a puff of smoke followed by readings which were considerably out of spec. So I have not yet powered it up pending a replacement PSU.

The Datasette looks very sketchy and I would be surprised if it works.

[JudgeBeeb]

A C128D :

It appears to be in excellent condition and works in both modes. Sadly, it doesn't have its keyboard anymore.

[JudgeBeeb]

By an enormous coincidence, a C128D keyboard which had parted company from its computer. :

Also, in excellent condition.

Looks great

[duikkie]

i did buy it for 1 euro

but how to use it

someone know this E(E)promer 3.0 : (c)2000
parallele poort.

DIY PROJECT from which book ? ( elektor/elektuur?) , pc ??

[flaxcottage]

Sorry I don't recognise the equipment, duikke, but if you look at this website https://www.americanradiohistory.com/index.htm they have a big library of scanned electronics magazines. You know the board is for the year 2000, so you could look at scans of Electur, ET, etc for the year 2000. You may even find it.

[markjw]

and to go with the ZX80 I picked up at the end of last week, an original Sinclair ZX 16K RAM pack

Elektor normally has an EPS number on the printed circuit board, even if it is home made. So, if there is no such number at the back side of the board then I'd advise to skip the Elektor magazines.
