    New batch available !

    After being frustrated with insanely high shipping costs and import taxes involved when trying to buy such RAM sticks from USA (where most of these can be bought it seems) I decided to make my own, of course plenty more got made than I need and the rest are up for grabs. If there's demand I will make more, it takes between 1 and 2 weeks to get new PCBs and chips.

    These are 4MByte 60ns 30pin SIMMs, *without parity*, You will need to configure your board not to need parity for normal operation.
    All of these sticks are tested at 40MHz bus speed with tightest timings on an OPTi 82C895 based board using Memtest86+ 4.10 to one flawless pass. Chips used are not NOS but there shouldn't be any sort of problems. 50MHz operation is now tested and works perfectly with 1 wait state on reads and none on writes on the same chipset !

    These sticks are available only in multiples of 4, size of one memory bank on a typical motherboard. I won't do other amounts. 4 sticks are 36€ (9€ per stick) and 8 sticks are 64€ (8€ per stick), higher quantities (12, 16, 20 ...) are 8€ per stick also.

    Shipping is 7.50€ to Austria, Belgium, Bulgaria, Spain, Holland, Iceland, Ireland, Italy, Greece, Latvia, Lithuania, Luxemburg, Malta, Moldova, Norway, Poland, Portugal, France, Sweden, Romania, Germany, Slovakia, Slovenia, Finland , Great Britain, Switzerland, Denmark, Czech Republic, Ukraine, Hungary, Belarus and Russia. For all other countries it is 8.45€ You'll get a tracking number when I have sent the package, it shouldn't take more than a week for the package to arrive within europe, not sure how long it might take for other countries.
    Within Estonia I'll use SmartPost XS size, cost is 2.59€. I can also use SmartPost to send things to Finland, cost is 10€ but it should be much faster than normal mail so this option is available if speed is a concern over cost.

    Payment is via PayPal, by means of me sending you an invoice to pay (I will need your PP address to do that). SEPA payment is also possible. Also provide your shipping address in the PM to make things smoother, alternatively I can use the address provided by PayPal.

      Great idea. Great work. Maybe I will need some in the short future. But sadly my A4000 is still under repair and I have some mixed SIMM setup that will have to be inspected thoroughly in respect of timing or other problems.

                      8 SIMMs are received and are absolutely beautiful Very good idea, now my 386DX-40 has 32 MB RAM instead of 8. The PCBs look very nice, dare I say even better than the original modules from back in the day.
