An Acorn AKA31 SCSI Podule off eBay and from CJE, an AEH54 Ethernet Podule and MEMC1A chip. Hopefully, this will let me get to the point being able to run RISC iX on one of my Archimedes.

It's fairly easy to convert the AEH54 to add an AUI connector, makes connecting it to an RJ45 based network easier. Just add a few resistors, swap a few links and add the connector. I even got Atomwide to sell me a new backplate back in the day.

...though, if you're not wanting to bodge vintage hardware, you can just buy an old hub on eBay for a tenner.

It's difficult to give those things away (I know, I've tried!) - There should be a setting, on eBay, for saying: Here's a tenner and I'll post it to you . . . :lol:

Dare I ask what on earth is going on down in that bottom-right corner? (-8

Why the curious staggered arrangement of links?

It’s a connector to a Papilio, an FPGA development board.

OK. That answers one question, but immediately raises another!

Admittedly, it's a question for the designers of PapilioOne. (-8

I think there is logic in the design. There are two central continuous rows of pins. Each of these is connected to an FPGA IO pin. There are then sets of four pins which jut out. These are power pins comprising 5v, 3.3v, 2.5v and GND.

Regardless of the layout it is a great little board. Probably the most accessible way for a hobbyist to get started with FPGAs.

Three PCBs I ordered from Aisler:

Some quick soldering later and the first board was ready to use:

Flash_cartridge_front.jpg

The order page is here and the repository containing the KiCad files is here.

I'll start a new thread in the 8-bit Hardware forum with more details.

Edit: 128K banked flash ROM cartridge thread started.

An HP-16C in almost mint condition. :D

HP-16C.jpg


I know it looks dusty in the photo but to the naked eye it looks superb. My camera hides nothing! :(

I have wanted one of these for years to save me working binary and hex out in my head. #-o Maybe it will make me lazy now. :lol:

They aren't exactly rare but good ones complete with manual and slip cover are hard to come by. They can be found in the USA but with postage and import duties added they become prohibitively expensive. :?

I bought both the 16C and 11C back in the mid 80s. Used them both throughout my working life. When I retired I sold the 16C (mint condition) - it sold for just under £100. I still have my 11C but don't use it anymore - so that's up for offers, if anyone is looking for one? I now use 16C and 11C apps on my iphone :o) Note: my 11C user Guide was lent to a colleague who eventually lost it during a move :? Available on-line, however.

p.s. I don't think I used more than 6 batteries, between them, during the 30 ish years in my possession!

Wait, is that a Stuka on the cover? On balance, I don't know whether I'd prefer being on the receiving end of one of those or given the task of typing any of these suckers in!

Will these scans be OCR'd? I've enjoyed a few PDFs where the text can be straight copied and pasted into the emulator.

Looks like a Spitfire to me. Stukas had a sort of bend in each wing so they were vaguely W shaped.

I'll have a second look....

Looks like they were trying for a Spitfire alright. But it doesn't look rounded enough where the wing meets the body for my taste. And the body looks thinner like a Stuka. That's my impression anyway.

But I suppose I can only judge the book by its cover. That's probably pretty sound.

Looks like there's a Jetpac game in there too. I shouldn't get my hopes up but I was a bit disappointed with the BBC version of the real Jetpac. The asteroids come in a blizzard on that one. Way too much.

I have today learnt that this is an absolutely brilliant design. The power pins are laid out symmetrically around the IO pins. If (as I was) you are stupid enough to plug the board in the wrong way round, the power pins remain connected correctly, The device won't work because all the IO mappings will be incorrect but nothing will be damaged.

A bunch of stuff from CPC (although some stuff is still missing after their second go at this...)

This should allow me to:-

Recap my Megadrive
Build an improved ZX81 tape loader
Rebuild a ZX81 I have striped down to the bare PCB

And have quite a lot of spare bits afterwards...

It’s a bumper harvest today!

C773EB97-41F6-4EC9-BE59-950CE83551F1.jpeg


All of them working!

Disc Hobbit, Battle of Britain and Castle Quest.
Tape Elite.

Nice!

I am having memory troubles with Battle of Britain though - it loads but keeps coming up with out of room errors on everything except Blockade. I have a datacentre connected to my beeb as well as normal disc drives. I guess that can’t be helping? :oops:
