I got myself some reprints for some good feeling of nostalgia!
#8bit #mos6502

I've just released Regenerator 2000 v0.7.0 with MCP Server support.
I've tested it with Claude Code and Gemini CLI and got impressive results: multi-line comments, good labels,etc.

The dual VIA interface for my PAL-2 is done ... now I shall finally be able to properly use my Gamesboard (tm)! #mos6502 #PAL2 #r6522

A protoboard with a large connector on the short side and two smaller ones along the long side of the board. On the board are also two small ICs and two larger ones, together with two sets of configuration jumpers, though most of the board is bare.

The back of the protoboard, showing a huge jumble of wires.

IT'S ALIVE..! #mos6502 #via #gamesboard

A PAL-2 SBC with a homebrew VIA interface board, which looks half finished. A 6502 Gamesboard(tm) is attached to the VIA interface using a ribbon cable and a bunch of patch wires. Various LEDs on the Gamesboard are lit.

So I've jumped on the #6502 bandwagon. I've been taking Ben Eater's 6502 setup and put it on a Tang Nano 9K #FPGA.

So far, so good... #PAL2 #mos6502

Have you written 6502 assembler code?

Now that you know the secret, you have no more excuses for not coding demos or games on COMMODORE 64!

Who needs 4K antialiasing, depth of field, ray-traced lighting, shadows, and motion blur when you can have a 'Games Board'? #nogpu #mos6502 #PAL2 #Sybex

A protoboard with 15 LEDs, 9 of which are arranged in a 3x3 square, with the remaining LEDs in a straight line below the square. Some of the LEDs are lit. To the right of the LEDs is a small keyboard with 16 keys arranged in a 4x4 square. Along the top of the protoboard are 4 ICs. The board is connected to a PAL-2 computer using a ribbon cable. Also visible is a copy of Zak's '6502 Computer Games' book.

Does anybody know where you can buy old/new stock of 6502 CPU's

The main CPU in the dimmer server rack that controls the main lighting system at one of the theatres I work at just died after 37 years of 24/7 use

Do they still make new 6502's anymore? And if they do, are as reliable as the old ones?

( I am still so impressed it survived nearly 40 years of use, this is the CPU I want at the end of the world)

#askfedi #mos6502

@peterb No, the first 25% or so is technical reference, the rest is example ASM programs against an idealized test device. You can learn a *LOT* by reading those programs.

Remove Element from Queue
Purpose: Memory locations 0042 and 0043 contain the address of the head of the queue(MSBsin0043).Placetheaddressofthefirstelement(head)ofa queue into memory locations 0040 and 0041 (MSBs in 0041) and update the queue to remove the element. Each element in the queue is two bytes long and contains the address of the next two-byte element in the queue. Thelastelementinthequeuecontainszerotoindicatethatthereisnonext element.
Queues are used to store data in the order in which it will be used, or tasks in the order in which they will be executed. The queue is a first-in, first-out data struc¬ ture; i.e.. elements are removed from the queue in the same order in which they were entered. Operating systems place tasks in queues so that they will be executed in the proper order. I/O drivers transfer data to or from queues so that it will be transmit¬ ted or handled in the proper order. Buffers may be queued so that the next available one can easily be found and those that are released can easily be added to the available storage. Queues may also be used to link requests for storage, timing, or I/O so that they can be satisfied in the correct order.
In real applications, each element in the queue will typically contain a large amount of informationorstoragespacebesidestheaddressrequiredtolinktheelementtothe next one.

Much better scan than the other copy, of Lance Levanthal's 6502 Assembly Language Programming:
https://archive.org/details/6502_Assembly_Language_Programming_by_Lance_Leventhal/mode/2up

Miserably hard book, 644 pages of insomnia-curing detail. SUPER useful if you really take your 6502 ASM seriously. I learned a lot but only after reading easier books, this one beat me as a yout'.

@fox_dev_random I just wonder... do we have a #FreeHardware (aka #OpenSource) reimplementation of #mos6502 #CPU?
