Re: GandALF, sub for 1541 custom IC MOS 325572-01

That is truely a work of art ...
I'll have to dig out my 2 x 1541s and check em over to see if they are needing anything..
btw ...I take it this would not work in a 1540 ?

Re: Impulse Ebay purchase was a good one..

I think you need to use an external hoster like postimg.org Ahhh that would explain a lot .. I have no such host ...unless dropbox is supported ? ..perhaps the host I chose at random for my avatar might allow larger images ? I'll take a look later . btw ..I chose the Punchy Avatar ...to remind me o...

1540 Floppy ..??

In my collection I have a 1540 Floppy drive.. I'm not sure if it still works ...since the last time it was powered up was over 25 years ago .. Looks like the 1541 ..but is vic coloured .. Not sure if it still has original roms ..as these may have been replaced to give full 1541 functionality. How ra...

Impulse Ebay purchase was a good one..

Made an impulse bid on a Vic on Sunday .. It just arrived today .. £25 including postage ..but had no PSU so sold as untested .. I was very pleasantly surprised when it powered up to a goodish picture on composite.. There is a modulator with it ..and bonus ..a 1630 C2N Datassette ....plus all origin...

Re: Image display on non CRT

S video looks to be the best option ...
I will probably go down that route.

Image display on non CRT

I'm sure this question has been asked many times before.. ..We now live in a word of LCD dispay etc ...and sadly I dont own a CRT monitor.. So how do you guys display your VICs if you also dont own CRTs ? Is it best to try and locate an LCD with RF input ? or are there mods that can be done to the V...

Re: Anyone still have good 6561-101 chips ?

Thanks for that ... As I said .. not opened a VIC for over 15 years so brain a little foggy .. How much for a VIC anyway ..as I have 2 workers so it wouldn't hurt to have a spare chip.. ..even if I pin down the faulty ram .. I guess I'll have to fit a full set of bases and start swapping .. most lik...

Anyone still have good 6561-101 chips ?

I recently pulled out of the loft and old VIC20 unit ..which didn't power up on account the rocker switch was faulty .. I found one on an old board and switched it out .. The Vic20 now powers up to a cyan border with garbage on screen .. multicoloured and flickering .. From my previous repairs in th...

I would like to echo those sentiments if I may..
My brother was fortunate in going in to work late this morning ..and so was still at Finsbury park station at the time the the first incident took place ..
My thoughts go out to those who's loved ones are not so lucky.
