Just a quick pic of the devkit made for Phoenix. This has been several months in the making, so I hope all the hard work is worth it

While it’s been too hot to solder in the labz, the GALEP-III multi-programmer has been working hard programming the GAL’s for some DivIDE boards. In total it programmed 45 GAL’s of which only 42 are pictured here due to 3 being used in a test DivIDE.

Well, after only an hours coding, the page write method is working. Using ’safe’ values to guarantee correct writes, a whole 8K eeprom can be written in roughly 3secs. Using the exact same ’safe’ values in byte write mode takes around 2m10s!
This pretty much concludes the adventures with the hardware side of Eprom Emul. The […]

A picture taken last night shortly after the successful programming of an eeprom using Eprom Emul.

Well, after a couple of days of frustration, the software for Eprom Emul is now working. Last night saw the momentus first ever successful write of a full rom image to an AT28C64B using the Eprom Emul. The bad news here is that because of the AT28C64B’s internal workings, to test my code correctly, I […]

After the last batch of boards got lost in the post, the second batch of boards arrived! I’ll start soldering later and should have one completed by the weekend. Ready for posting on Monday

The code for ps2km is ready to put into a prototype system. This will be done over the coming days.
More ideas for the ps2km include classic and wheel startup modes, selectable by different mouse button combos on power-up/reset.
Classic mode will disable the scroll bits so the buttons byte will work as a normal kmouse (inactive […]

Here’s the how I plan to implement the PS/2 mouse bytes into kempston mouse bytes.
X and Y bytes are as normal for KMouse. Mouse Coords 0,0 = bottom left, 255,255 = top right.
Button Byte is as follows:
Bit 0 = RMB
Bit 1 = LMB
Bit 2 = MMB
Bit 3 = Z Change Bit
Bit 4 = Z Scroll […]

Well, I’ve finally got round to making a blog for all papaya labz developments. I wonder how many people will visit us

Well after contacting the board makers about a week ago to say the Eprom Emul boards hadn’t arrived, the new ones have now been shipped and should be with us soon. All free of charge
