So you're holding the thread hostage in the interim ?

Re: New generation of PLA - PLAnkton

In the best of case you are an incompetent, in the other case you are a liar (or both). This is not an 'opinion', this is throwing insults. Stop trolling my thread. Back in 2016, Mitch Farley reported he accidentally inserted his PLAnkton in the socket for the SID and this caused no damage at all t...

Re: New generation of PLA - PLAnkton

Also note the voltage at the CPLD does not have a linear relation with the voltage at pin 28 -> 4.75-3.52=1.23V while 5.25-3.895=1.355V Are you sure you have some kind of technical education? My nephew can explain you the difference between LINEAR and DIRECT relationship, the first is when INCREMEN...

Re: JiffyDOS on Oceanic OC-118 aka Excelerator+

I have one of these floppy drives, which were basically 1541 clones with an external power supply. This drive apparently ships with a JiffyDOS 5.0 ROM and a second socket that can be populated with an alternative ROM and activated with a dip switch. I used the drive with my stock C64 back in the da...

Bare bones...

Back in 2008, it was a strict minimum multicart compared to the Megacart.

Re: New generation of PLA - PLAnkton

5.25V is the limit of the TTL chip, not of the board: feed the C64 Vcc line to read 5,25V on pin 14-28 of plankton an then read the Vcc on CPLD. My power supply (which I used at the WoC in december) provides 5.12V on the 5Vdc line. Once past the power filter, the voltage measurable on the 250466 as...

Re: HASL for cartridges? (split/OT from: Cheese & Onion)

That would be best IMO. But for low cost I think non-beveled is also an option for me for now at least. BTW, I noted the plating on the VIC-20cr connector is pure tin. That's not the same at all as HASL which is an alloy of different metals to make it's fusion point lower and make it softer. My poi...

Re: New generation of PLA - PLAnkton

5.25V is the limit of the TTL chip, not of the board: feed the C64 Vcc line to read 5,25V on pin 14-28 of plankton an then read the Vcc on CPLD. There are 3 different types of ICs on the standard breadbin C64; TTL (all 74LSxx), CMOS (DRAM and color SRAM) and NMOS (all 65xx). All 3 have different ch...

Re: New generation of PLA - PLAnkton

People that make everything but not simply to measure with a voltmeter the Vcc on the CPLD! I'm sorry, I can't make sense of that sentence... If eslapion trust in it's opinion he can supply a C64 with 5,25V (or 7V) mesuring this voltage between pin 14 and 28 of the plankton and posting the pics of ...
