hold down option when you boot without a cart for self-test there is a keyboard test included

people who do motorcycle restoration of rubber parts recommend a soak in 50/50 alcohol and methyl-salicylate (oil of wintergreen) it worked on my inlet rubber but never tried it on belts

here is a link: the piggyback method is quicker and less involved but you need sapre RAM chips to do it. the user in the above link, tf_hh makes a device called "sys-check II" which diagnoses memory faults. it also has a 512kb upgrade and ROM 'slots'. a v.useful device ?

you may have an issue with the extended 64k bank. you can try the piggyback method or there is another mod you can do to make the 2 banks 'swap places' to diagnose this - it involves switching 2x resistors so that they cross over instead of side by side. the info will be in the forum here. then the second bank will be the primary one which is tested by the inbuilt tester. try to test RAM with software called XRAM or SHORTEST as they are compatible with the various extended memory banking schemes. good luck!

sys-check II is a solderless memory upgrade:

ah no probs ? if theyre pricey and selling then go for it. someone interested in an A3000 ought to know more than the average amiga dabbler so you shouldnt have to describe every meticulous detail. the different hardware options will vary the value and an enthusiast will appreciate this sort of thing. you might get some interest on the buy/sell section here but do check out amibay if you havent already as it has a lot of users who like to collect

i wasnt criticising you, i was just trying to be helpful to you and any other readers

on ebay be sure to click "sold listings" to get an idea of what people have really paid / are prepared to pay. many items are listed with a high price but never actually sell, they just sit there then get relisted over and over. these instances are not a useful reference. however, many buyers on there want something for nothing so it might be worth checking the amibay site. its a more realistic environment for retro buying/selling as the people are more knowledgeable.

nice work, 4 channel chiptunes are much better than 3 channel *cough-ommodore*

i believe at the time the price of RAM was the big issue

great success!

not an easy task, i cant find it neither but youre in the right place to request a scan. english software would often release games under licence. it is the same game but alas, it doesnt help your crusade. hopefully the synapse boxart is more appealing!!

screaming wings by red rat software had a winged logo loading screen but i dont think it was a skull. it might be worth a look in case your memory is fogged

at just under 14 quid it is very reasonably priced..

nice one, dont trim the atari - trim the card! ?

much appreciated! ?

is it still beneficial to remove the blurring cap even if you already have UAV installed?

800XLFs can be identified from the outside as they have a small cover (like the parallel port cover) between the power and monitor ports. altho this may only apply to PAL variants, as i havent seen an NTSC one

have you ever had to attach a donor leg when the break is very close to the chip body? i have a DRAM chip with a broken leg that has next to nothing exposed. does anyone know if can i 'dremel' the body to expose more contact?

ANTIC generates the characters for the GTIA to display on the screen so swap them out if you can

how rude!

sounds like you have a good session lined up hehe ? test with your favourite games but also try 64k games too. it should behave just like an 800XL after the RAM mod. the inbuilt RAM self-test should be booted with option held in order not to load basic. UAV is super-sharp compared to standard so any software will give pleasing results

1.2mb disks are labeled: "HD" and are not compatible you want: "DD" or "2D"

you need blank disks to experiment with. set 1050 to D2. use SIO2PC to load a copier (e.g. MyCopyR or Copy2000) copy an ATR file via SIO2PC D1 to the blank disk in D2. set 1050 to D1, boot the disk and see if it copied ok

600XLs dont have the RAM or keyboard issues of the XE models. XLs are generally more robust than XEs
